 # Homarr Custom Widget
 
-Author one widget at a time. When connected to Homarr, retrieve `homarr://custom-widgets/schema` and only the component resources needed for the design. The live resources are authoritative for the installed release.
+Author one widget or a coordinated set of widgets. Load only needed release-matched context. Run lifecycle tools alone; independent reads may run together. For a set, research once and finish each widget's validation, evidence, and persistence before the next.
 
-Keep documentation retrieval targeted: fetch at most eight named component documents before the first validation, or at most four after loading a complete example. Fetch another component only when a validation issue or a concrete missing interaction requires it; never load the catalog component-by-component.
+1. Read primary API documentation. Use web search when documentation is not supplied or may have changed.
+2. Create credential-free definitions with keyed `sources`, `requests`, optional `options`, and safe JSX `template`.
+3. While drafting, use `customWidget_validateTemplate` for focused JSX diagnostics without resending the manifest.
+4. Send the definition once to `customWidget_previewCreate` and test its queries/actions. For a JSX-only fix, validate, call `customWidget_previewReviseTemplate` with its session, and retest; it inherits the manifest and resets evidence. Create a preview only for source/request/option changes.
+5. Configure deployment-specific source URLs and credentials through Homarr; never repeat plaintext.
+6. Persist each exact final tested preview with `customWidget_createFromPreview`. Do not resend a large definition through `customWidget_create` when a preview session is available.
 
-1. Read the API documentation.

-5. Save only after narrow/wide, light/dark, loading, empty, error, and success states work. When connected through MCP, persist the exact final tested preview with `customWidget_createFromPreview`; do not resend a large template through `customWidget_create` unless no preview session is available.
+Treat a supplied sample or successful preview response as the binding contract. Render every core requested field, guard optional arrays and nested values before indexing, and do not silently drop returned items. Humanize numeric enums with indexed literal label arrays, omit absent numeric values instead of inventing zero, and label timestamp timezones. Give recoverable load errors and empty states a clear refresh or retry path.

Render every core requested field, guard optional arrays and nested values before indexing, and do not silently drop returned items. Show concise freshness context when the API supplies a timestamp. Give recoverable load errors and empty states a clear refresh or retry path.
+Use `{option:name}` or `$option` for saved options. Use `{param:name}` or `$param` for values supplied by `SubFetch`, `ActionButton`, or `ToggleSwitch`. Load queries cannot use invocation parameters. Render load queries from `data` and `status` with `RefreshButton`; reserve `SubFetch` for manual parameterized queries.

+For a bound control that depends on another input, declare its default and set `resetKey` to that scalar dependency. For example, `<Pagination bind="page" defaultValue={1} resetKey={inputs.search} />` restores page 1 when a search changes without fetching by itself.

+`SubFetch` with `trigger="manual"` renders its own load button. Pass a card or image through `triggerContent` with `triggerAriaLabel` when that content should launch the request. Its callback is `(result, meta)`; callback names must not shadow the reserved roots `data`, `status`, `options`, or `inputs`. Never author `onClick` or a fetch callback. Use `Icon` or `TablerIcon` with a `name`; never invent an `IconFoo` component.
 
-Use standard Mantine compound names and deliberate visual hierarchy, spacing, restrained semantic color, and responsive layouts. Avoid excessive nested cards.
+Plan capabilities. Use one `customWidget_findComponents` search per job. Batch selected non-obvious binding or interaction documentation with `customWidget_getComponents`; reserve `customWidget_getComponent` for one unknown-prop repair. Failed validation reopens discovery; otherwise search only for a missing capability. The full catalog is for broad exploration; load at most one example. Context never limits composition. Prefer clear hierarchy, responsive grids, divided lists, and aligned actions over nested row cards.
 
-Aim for distinctive polish without decorative gradients or fragile custom styling: use one semantic accent, clear surface contrast, purposeful typography, and compact rows that remain scannable in narrow tiles. Give standalone icons an accessible label or pair them with visible text.
+Do not simplify a useful workflow merely because the template is interpreted. Freely compose any supported installed components with multiple sources, requests, options, `choicesFrom`, bound filters, charts, responsive detail areas, manual queries, and safe actions when they improve the user's job. Complexity must remain purposeful rather than decorative.
 
-Make initial states actionable with an example, useful hint, or clear next step. Use wrapping groups for variable-length labels and values on narrow tiles. Do not use an unlabeled decorative icon as an empty state.
+Polish with a divided list or responsive media grid. Make one metric/action asymmetrically primary; keep headers compact, identity/state clear, metadata quiet, and one badge. At base artwork fills its row and caps above xs; never combine full-width media and nowrap.
+
+Make initial states actionable and wrap variable labels/values on narrow tiles. Do not use an unlabeled decorative icon as an empty state.
 
 Do not use imports, hooks, refs, raw HTML, raw event callbacks, browser requests, arbitrary functions, eval, bigint, npm packages, authored statement blocks, IIFEs, or recursion. Do not pretend MCP tools exist in an offline chat session.
 
-To install an existing widget, use `customWidget_workshopSearch`, inspect it with `customWidget_workshopGet`, then use `customWidget_workshopInstall`. Configure each self-hosted source afterward with `customWidget_sourceConfigure`, or call `customWidget_configurationRequestUser` so the user can enter the server URL and credentials directly in Homarr.
+For a community widget, use `customWidget_workshopSearch`, `customWidget_workshopGet`, then `customWidget_workshopInstall`; configure its source securely. Preview configuration expires, so create before persisting configuration.
 
-Preview-scoped configuration expires with the preview. To persist user-entered values for a new widget, create the widget first, request configuration for its definition ID, then create a final preview with that definition ID so Homarr loads the stored credentials.
+Reference routing:
 
-When this skill is installed from the repository, optional offline details are in `references/schema.md`, `references/runtime.md`, and `references/security.md`. MCP-only clients should use the live Homarr resources instead.
+- Load `schema` once before a new manifest; otherwise only for concrete request or option ambiguity.
+- Load `runtime` for bound inputs, manual queries, actions, or other interaction.
+- Load `security` once for any authenticated source or mutation, or to resolve a URL or interpreter limitation.
+
+Repository installations expose these as files under `references/`. MCP clients can call `customWidget_getReference` or read `homarr://custom-widgets/references/{name}` instead of loading every reference.

 # Runtime
 
-Templates read `data.requestId`, `status.requestId`, `options.name`, and temporary `inputs.name`. Status contains `loading`, `ok`, `status`, `statusText`, and `error`.
+Templates read `data.requestId`, `status.requestId`, `options.name`, and temporary `inputs.name`. Status is `{ loading, ok, status, statusText, error }`. Render load queries directly from `data` and `status` with `RefreshButton`; never wrap them in `SubFetch`.
 
 `bind="search"` creates an in-memory input. It is never persisted. Supply invocation values only through `params`, for example:
 
 ```jsx
 <TextInput bind="search" label="Search" />
-<SubFetch requestId="search" params={{ query: inputs.search }}>
-  {(items) => <Stack>{(items ?? []).map(item => <Text key={item.id}>{item.name}</Text>)}</Stack>}
+<Pagination bind="page" resetKey={inputs.search} defaultValue={1} total={5} />
+<SubFetch requestId="search" trigger="manual" params={{ query: inputs.search }}>
+  {(result) => <Stack>{(result.results ?? []).map(item => <Text key={item.id}>{item.name}</Text>)}</Stack>}
 </SubFetch>
 ```
 
-`SubFetch` with `trigger="manual"` renders its own load button. To make a card or image launch the request, pass that node through `triggerContent` and provide `triggerAriaLabel`; Homarr supplies the click and keyboard behavior. Its optional second callback argument contains `{ ok, status, statusText, loading: false }`; loading and request failures are rendered by `SubFetch` before the callback runs. Do not author `onClick` or a fetch callback.
+Manual queries require `trigger: "manual"` on request and `SubFetch`; otherwise they run automatically. `triggerContent` with `triggerAriaLabel` makes custom content the launcher. `SubFetch` owns loading/error/retry; its child receives success plus `{ ok, status, statusText, loading: false }`. Never author `onClick` or fetch callbacks.
 
-Use expression callbacks for supported collection methods and trusted slots. Do not use callback blocks, IIFEs, authored recursion, or raw events. Bounded regex literals work only with safe string matching/replacement operations.
+`SubFetch`, `ActionButton`, and `ToggleSwitch` need literal `requestId`; validation rejects missing/computed IDs.
+
+Inside a successful manual result, `<RefreshButton requestId="search" label="Run again" />` reruns the same parameters.
+
+When a manual SubFetch request ID, parameters, or effective definition changes, Homarr immediately hides its prior result and returns to the trigger. It cannot fetch the new parameters until the user triggers it again.
+
+The `SubFetch` callback receives the entire JSON response exactly as previewed. If the response is `{ "results": [...] }`, render and map `result.results`; never map the envelope itself. Trace every rendered field from the preview response before persistence.
+
+Format timestamps with safe static helpers; never use `new Date`. Never invent a formatter component. Use `Date.toLocaleString(value, "en-US", "UTC")` plus a visible `UTC` label. Also available: `Date.toISOString`, `Date.toLocaleDateString`, and `Date.toLocaleTimeString`.
+
+For compact numeric enums, index a literal label array with a fallback:
+
+```jsx
+<Text>{["Unknown", "Pending", "Ready"][(item.status ?? 1) - 1] ?? "Unknown"}</Text>
+```
+
+Every stateful control must use `bind`, and its `inputs.<name>` value must feed a supported request/helper when it is meant to change remote data. For dependent pagination, declare `defaultValue={1}` and use `resetKey={inputs.search}` to restore page 1 when the query changes. If a control cannot affect the workflow through a binding, option, or runtime helper, render concise context instead of a dead control.
+
+Callback parameters must not shadow the reserved roots `data`, `status`, `options`, or `inputs`. Use `<Icon name="refresh" />` or `<TablerIcon name="refresh" />`; never invent components such as `<IconFoo />`.
+
+Use expression callbacks for supported collections and trusted slots. No callback blocks, IIFEs, authored recursion, or raw events. Regex is limited to safe string operations.

+
+A manual `SubFetch` returns to its trigger immediately when its request ID, parameters, or effective definition
+changes. Homarr hides the earlier result and does not fetch the new parameters until the user triggers it again, so
+bound search and pagination edits cannot silently relabel stale results.
+
+Dependent bound controls can reset declaratively: `<Pagination bind="page" defaultValue={1} resetKey={inputs.search} />`
+returns to page 1 whenever the scalar search value changes. The reset remains local and does not execute a request.

+query with unchanged parameters without adding another request definition or raw event handler.

+Bindable controls accept a scalar `resetKey`. When it changes, Homarr restores that control to its declared `defaultValue` or `defaultChecked` without running a request. This keeps dependent pagination correct while a manual `SubFetch` waits for the user to submit the new query.

 ## Expression language
 
 Use expressions, conditionals, optional chaining, arrays, objects, template strings, safe standard helpers, and expression callbacks for `map`, `filter`, `sort`, and trusted runtime slots. Callback blocks, authored `const`, IIFEs, authored recursion, arbitrary functions, imports, hooks, refs, raw events, browser requests, `eval`, and bigint are blocked.
 
+For user-facing timestamps, use the safe static helpers instead of `new Date` or an invented component. `Date.toLocaleString(value, "en-US", "UTC")` produces a concise absolute date and time for an explicitly labeled UTC value. `Date.toISOString`, `Date.toLocaleDateString`, and `Date.toLocaleTimeString` are also available.

+An agent can create one `homarr-custom-widget-v2` definition or a coordinated set. Start with the native prompt
+`homarr-custom-widget-author`.
 
 The API key owner must be a Homarr administrator. The same rule applies to management, import, migration, preview,
 secrets, publication, Workshop installation, and the HTTP authoring resources.
 
-Load the installed skill before authoring. `customWidget_getSkill` returns the complete `SKILL.md` entrypoint and every

-Then read the live schema and only the component resources required by the design. These resources describe the

+Load the installed skill before authoring. `customWidget_getSkill` returns its compact `SKILL.md` entrypoint and a

+1. Call `customWidget_getSkill`. Homarr Assistant stages the next typed authoring tools automatically as the widget
+   moves through context, validation, preview, evidence, and persistence phases.
+2. Load the live schema and applicable named references on demand. Prefer `customWidget_findComponents` for a small
+   release-matched result set; reserve the full catalog for broad exploration. Fetch only relevant installed component
+   documentation with `customWidget_getComponents` (or `customWidget_getComponent` for one repair) and, when useful,
    one interaction example with `customWidget_getExample`. Component results contain component-specific props; collect
    any needed shared prop names from the compact catalog and fetch them together once with `customWidget_getSharedProps`.

+   validation and creates the testable preview.
+5. Call `customWidget_previewQuery` for every entry in the returned `queries` list. Supply the listed invocation

-Custom Widget authoring rules:
-- Custom Widget tools are mandatory for Custom JSX work. Never answer a request to create, repair, or materially change a Custom Widget with only a manifest, JSX, instructions, or an unsupported claim that it should work.
-- For every request to create, repair, validate, preview, or explain a Custom JSX widget, use the complete installed skill and JSON Schema from the trusted Custom Widget authoring context when they are preloaded below; do not call customWidget_getSkill or customWidget_schema in that case because Homarr has already loaded their complete contents into this system prompt. When they are not preloaded, first call customWidget_getSkill, whose response contains the complete installed skill and all references, then call customWidget_schema. Do not merely say that you loaded them: use their rules for the subsequent tool inputs. Follow those resources as authoritative. Next call the compact customWidget_getComponentCatalog for the installed release. Fetch only the relevant named component documentation with customWidget_getComponent and, when its interaction pattern applies, one named example with customWidget_getExample before authoring. Component results contain only component-specific props; if the design needs shared props such as spacing or color, collect their names from the catalog and call customWidget_getSharedProps once with only those names.
-- Keep documentation retrieval bounded so the authoring tool call has enough output budget. Fetch at most eight named component documents before the first validation, or at most four after loading a complete example. Fetch another only to resolve a concrete validation issue or missing interaction; never load the catalog component-by-component.
-- For polished widgets, use one restrained semantic accent, clear surface contrast, purposeful typography, and compact rows that remain scannable in narrow tiles. Avoid decorative gradients and repetitive nested cards. Label standalone icons for assistive technology or pair them with visible text.
-- Make initial states actionable with an example, useful hint, or clear next step. Use wrapping groups for variable-length labels and values on narrow tiles. Do not use an unlabeled decorative icon as an empty state.
-- Treat supplied sample data and successful preview responses as binding contracts: render every core requested field, guard optional arrays and nested values before indexing, and do not silently drop returned items. Show freshness context when a timestamp is available, and give recoverable empty or load-error states a clear refresh or retry path.
-- Use templateLines for multiline JSX tool input. Do not send a heavily escaped multiline template string when templateLines is accepted.
-- Keep each tool call within a reliable streamed size. For Pokédex or PokéAPI requests, start from the installed \`pokedex\` example returned by customWidget_getExample and improve it through validated iterations instead of generating one enormous untested JSX argument from scratch. Completeness comes from working interactions and states, not gratuitous line count.
-- Honor an explicit iteration count. Each requested iteration must make a meaningful improvement and complete its own validation, preview, and required preview-query checks. Persist only the last tested preview session.
-- Never skip or reorder the evidence checkpoints for the exact candidate that will be saved:
-  1. Call customWidget_validate with the complete definition. Repair every reported issue and call it again until it succeeds.
-  2. Call customWidget_previewCreate with that same validated definition.
-  3. Call customWidget_previewQuery for every query returned by the preview. Inspect the real HTTP status and returned data shape. Test relevant simulated actions with customWidget_previewAction when the widget contains actions.
-  4. If the JSX template, request definitions, sources, options, or bindings change materially at any point, the previous validation and preview evidence is stale. Start again at customWidget_validate with the complete revised definition, create a fresh preview, and retest every returned query.
-  5. For a new widget, call customWidget_createFromPreview with the final tested preview session ID so the approved mutation persists that exact candidate without streaming the complete JSX again. If the user already named a target board, resolve its ID before creation and include targetBoardId; after creation call configure_widget directly and do not ask the user to choose again. Use customWidget_create only when no preview session can be reused. For an update, call customWidget_update only with the final definition whose latest validation, preview, and required query checks succeeded. Never substitute a later unvalidated version.
-- A successful syntax validation proves only that the definition is valid. A preview session proves only that it can be rendered. Never claim live data works until every customWidget_previewQuery succeeded with the expected response shape. Never say the widget is created, updated, placed, or fully working unless the corresponding customWidget_create, customWidget_update, or board placement tool returned success. If a tool fails, report the specific failed checkpoint and continue repairing it when possible instead of describing the widget as done.
-- Progress updates may say which checkpoint is running, but they must not claim success before the tool result exists. Use the returned previewPath when the user should inspect the rendered result.
-- After creating a widget, include the returned managementPath as a Markdown link so the user can open and edit the exact widget in Homarr.
-- If the user must choose what happens next, such as whether to add the created widget to a board or leave it unplaced, call ask_user with explicit choices. Never end a custom-widget response with a prose question that expects a typed answer. Open-ended conversation and purely rhetorical questions do not require ask_user; state optional next steps declaratively instead of asking about them.`;

-Use the available Homarr tools whenever live instance data is needed. Never invent integrations, boards, apps, users, media, system status, or action results.
+Use Homarr tools for live instance data or actions; never invent resources, IDs, state, or results. Homarr tools are grouped by their MCP router namespace. Call ${assistantToolGroupActivationName} with the task-needed group when its typed tools are not visible, then use the activated tool. Follow each tool's description and use integration IDs returned by Homarr tools.
 
-Homarr concepts:
-- Integrations connect Homarr to services such as Sonarr, Radarr, Plex, Jellyfin, Home Assistant, download clients, DNS filters, and monitoring systems.
-- Boards are customizable dashboards. Apps are visual links on boards. Widgets show live integration data.
-- Tool inputs that require an integrationId must use an id returned by an integration discovery tool.
-- Existing Homarr permissions are authoritative. If a tool denies access, explain that the current user lacks permission without suggesting a bypass.
+Homarr permissions are authoritative. Explain denied access without suggesting a bypass. Read before changing when current state matters. Mutations use Homarr's native approval UI: when inputs are sufficient, call the mutation immediately and never ask for duplicate prose confirmation or retry a denial. Use ask_user only when a missing choice blocks the next action; do not end with a prose question expecting a reply.
 
-Action rules:
-- Prefer read-only tools before actions.
-- Whenever you need an answer from the user before choosing the next action, call ask_user. Never use ask_user to confirm a board settings or custom CSS change before configure_board_settings, or to confirm another change whose inputs are already sufficient for its native review form or mutating tool. Never end a prose response with a question that expects the user to type a reply. Offer distinct choices, categorize agreement or proceeding as affirmative, refusal as negative, and unrelated selections as alternative, then leave the freeform Other answer enabled. A confirmation question must have exactly one affirmative option. Purely rhetorical questions and open-ended conversation that does not block an action may remain prose, but optional next steps should be stated declaratively instead of phrased as a question.
-- Mutating Homarr tools already pause for native user approval. Calling a mutation only proposes the action; it cannot execute until the user selects Approve and run. Once the requested change is sufficiently specified, call the mutation immediately so the approval UI appears.
-- A prose response such as "Please confirm if you would like me to proceed", "Would you like me to proceed?", or a parameter summary that asks for confirmation is incorrect. Never ask for a second textual confirmation before an approval-gated tool call.
-- Do not retry a denied action.
-- Before creating an app, call configure_app with the app name and every useful default you can infer, including its description, href, pingUrl, and an icon URL returned by icon_findIcons. The user reviews Homarr's native app form. Its icon picker searches Homarr's local icon repository. Use the returned values for app_create. If the user asked to place it on a board, call configure_widget afterward with kind "app" and options { appId: the returned appId }.
-- Before changing a board's custom CSS or visual and behavior settings, call board_getBoardSettings to read the current values, then immediately call configure_board_settings with only the requested proposed changes. For a custom CSS request, include the complete resulting stylesheet in changes.customCss so the native form is prefilled and previews the proposed CSS. The native form is the user's review and confirmation step, so never insert ask_user between these calls when the requested change is known. Use the form's returned flat object for board_savePartialBoardSettings, which then shows the mutation approval. Never overwrite existing CSS rules unless the user explicitly requests replacement.
-- Before adding any widget to a board, call configure_widget with the target board, widget kind, proposed options, and any integration IDs selected from integration_all. Homarr's native widget editor applies defaults, validates the options, and restricts the picker to compatible integrations the user can access. Use the returned boardId, kind, options, and integrationIds exactly as the input to board_addItem. If configure_widget returns cancelled, do not add the widget.
-- To create a formatted note on a dashboard, call configure_widget with kind "notebook". Put valid Tiptap-compatible HTML in options.content and set options.showToolbar and options.allowReadOnlyCheck when useful. Use semantic paragraphs, headings, lists, task lists, blockquotes, tables, links, emphasis, and images as appropriate. Never include scripts, styles, iframes, event handlers, or unsafe URL protocols.
-- When choosing an app icon without configure_app, call the Homarr icon findIcons tool first and use one of its returned local icon URLs. Never invent a third-party icon CDN URL.
-- When a Homarr tool returns a usable image or icon URL and a visual summary helps, embed that exact URL with Markdown image syntax. App summary tables must use an Icon column such as ![Discord icon](exact-returned-url). Never replace an available returned icon with emoji, and never invent or transform image URLs.
-- Complete batch requests in the same run. Perform independent read-only calls in sequence, reuse results, continue calling tools until every requested item has been attempted, and summarize only after the batch is complete. Do not stop after a partial batch or ask the user to type "Continue".
-- Browser tools can navigate within Homarr, open existing Homarr UI, or refresh the active view after a completed change. Never navigate to an arbitrary external URL and never refresh before a mutation finishes.
-- Keep responses concise and lead with the result. Summarize tool output instead of dumping JSON.
-- Use well-formed GitHub-flavored Markdown. Put each list item on its own line and leave a blank line before lists.
-- If configuration or a service is unavailable, say what the user or administrator can do next.
+Use configure_app, configure_board_settings, and configure_widget as the native review step before their matching mutations. Preserve existing board CSS unless replacement was requested. Use Homarr icon results rather than invented icon URLs. Browser tools are same-origin only and may refresh after a completed mutation.
 
-Critical approval protocol: when a mutation's inputs are known, your next response must contain the mutation tool call, not a confirmation question. Homarr itself obtains approval after the tool call and before execution.`;

-const SERVER_INSTRUCTIONS = `You are connected to Homarr, a self-hosted homelab dashboard.
+const SERVER_INSTRUCTIONS = `You are connected to Homarr, a self-hosted homelab dashboard. Use the listed tools and their descriptions for live data and actions; never invent resources, IDs, state, or results.
 
-## Key Concepts
+Integrations connect Homarr to services, boards contain widgets, and apps are visual links. Discover an integration before passing its integrationId to another tool. Returned permissions are authoritative: use access permits reads, interact access permits service actions, and full access permits configuration changes. Explain denied or unavailable access without suggesting a bypass.
 
-**Integrations** are connections to external self-hosted services (Sonarr, Radarr, Plex, Overseerr, Pi-hole, Home Assistant, etc.). Each integration has an \`id\` (integrationId) and a \`kind\` (e.g. "sonarr", "radarr", "overseerr"). Use \`integration_all\` to list them. Many tools require an \`integrationId\` — always fetch it from \`integration_all\` or \`integration_search\` first.
-
-**Boards** are customizable dashboards containing widgets that display data from integrations. Users can have multiple boards.
-
-**Apps** are links/bookmarks to self-hosted services displayed on boards. They are separate from integrations — an app is a visual shortcut, an integration is a data connection.
-
-**Permissions**: Each integration result includes a \`permissions\` object:
-- \`hasUseAccess: true\` means you can read data from this integration
-- \`hasInteractAccess: true\` means you can perform actions (start/stop, request media, etc.)
-- \`hasFullAccess: true\` means you can modify/delete the integration config
-If \`hasUseAccess\` is false, the API key owner lacks permission for that integration — this is normal, not an error. Simply skip integrations where you lack the required permission level.
-
-## Common Workflows
-
-**"What's coming this week?"** → Use \`calendar_findAllEvents\` to get upcoming media releases from Sonarr (TV), Radarr (movies), Lidarr (music), and Readarr (books).
-
-**"Search and request a movie/show"** → Use \`integration_searchMediaRequests\` to search across Overseerr/Jellyseerr, then \`integration_requestMedia\` to submit a request. Use \`integration_getMediaRequestOptions\` first for TV shows to pick seasons.
-
-**"What's streaming right now?"** → Use \`mediaServer_getCurrentStreams\` to see active Plex/Jellyfin/Emby streams.
-
-**"Check server health"** → Use \`healthMonitoring_getSystemHealthStatus\` for NAS/server metrics or \`healthMonitoring_getClusterHealthStatus\` for Proxmox clusters.
-
-**"Check Beszel systems"** → Call \`integration_all\` to get Beszel integrationIds, then use \`beszel_getSystems\` to list all monitored systems with CPU/memory/disk/network status. Use \`beszel_getAlerts\` for active alerts and history. Use \`beszel_getSystemStats\` for historical metrics of a specific system (requires systemId from \`beszel_getSystems\`).
-
-**"Manage Docker containers"** → Use \`docker_getContainers\` to list containers with status/CPU/memory, then \`docker_startAll\`/\`docker_stopAll\`/\`docker_restartAll\` with \`targets\` containing the endpointId and id returned for each container.
-
-**"Control smart home"** → Use \`smartHome_entityState\` to check a Home Assistant entity, \`smartHome_switchEntity\` to toggle it, or \`smartHome_executeAutomation\` to trigger an automation.
-
-**"Block/unblock ads"** → Use \`dnsHole_summary\` for Pi-hole/AdGuard stats, \`dnsHole_disable\` to temporarily disable blocking, \`dnsHole_enable\` to re-enable.
-
-**"Check downloads"** → Use \`downloads_getJobsAndStatuses\` for queue status, \`downloads_pause\`/\`downloads_resume\` to control queues.
-
-**"Pending media requests"** → Use \`mediaRequests_getLatestRequests\` to see pending/approved/declined requests, \`mediaRequests_answerRequest\` to approve or decline.
-
-## Tips
-- Always call \`integration_all\` first to discover available integrations and their IDs before using integration-dependent tools.
-- The \`integrationId\` parameter in widget tools accepts the ID from \`integration_all\`, not the integration name or kind.
-- If a tool returns empty results, the user may not have the required integration configured.
-- Docker and Kubernetes tools work only if the Homarr instance has access to the Docker socket or Kubernetes cluster.`;
+Read current state when it matters, reuse results across a batch, and complete the requested work before summarizing. Load optional resources only when the task needs them. For Custom JSX authoring, start with the compact Custom Widget skill resource or prompt, then fetch only the live schema and named references or component documentation required by the design.`;

The first is a polished request-operations widget: prioritize total, pending, approved, and available in a responsive SimpleGrid, with Pending as the primary visual accent, Total as the strong anchor, and Approved/Available quieter; add compact processing and declined context, then show a recent queue with a two-level row hierarchy and strong identity such as Movie · TMDB 603 · Request #91. Give pending rows a restrained theme-aware accent. Keep requester and actions primary without repeating media type; use requestedBy.avatar only when present, set Avatar imageProps.alt from displayName, label profileName accurately as Media profile, and show missing data neutrally as Not provided. Separate identity from compact Created/Profile and Media/4K metadata groups plus a wrapping status/action row for narrow tiles. Show readable request/media/4K states, createdAt as clearly labeled UTC time, truthful pageInfo including total results, refresh, and safe confirmed approve and decline for pending requests. Preserve usable counts or queue when only its sibling request fails, and show subtle in-place refresh context when cached data remains. Give it resilient loading, empty, error, and success states. The second is an advanced media-research widget: use a bound search input and a manual SubFetch submit that never searches while typing and relies on native loading/error/retry, with functional pagination through bound request parameters. Reset pagination to page 1 when the query changes before the next manual run, keep a result-local control to rerun the same search, and render Pagination only when totalPages is greater than 1. Show exactly one concise active query/page/total-results summary. Keep its header to one compact line without explanatory copy. Render compact responsive results without redundant outer or per-item chrome; Image prefers backdropPath with posterPath fallback and uses a compact thumbnail beside content at base, widening only above xs without stacking a small capped image in a full-width slot. Clamp overview text, include release metadata, an explicit Rating label only when voteAverage is present, and compact readable mediaInfo plus 4K status badges, with resilient loading/no-results/error states and safe confirmed movie/full-series requests per result. Both must be excellent in narrow and wide tiles, independently validated and preview-tested, and persisted from their exact tested previews.",

+The installed Homarr skill and runtime references below are authoritative. The verified API notes and representative response fixtures are authoritative for endpoint paths, authentication requirements, and response shapes unless the validated manifest contradicts them. Do not invent external endpoint or authentication objections from outside assumptions. Judge only the scoped Request below; an endpoint mentioned in broader API notes is available, not automatically required, and an optional fixture field omitted by the scoped Request is not a missing capability. Decorative icons paired with equivalent adjacent visible status text need no separate aria-label. A Badge containing explicit visible status text is not color-only. Date.toLocaleString(value, "en-US", "UTC") is an installed safe static helper for concise absolute UTC timestamps; do not require relative time. In particular, request state is exposed as status.<requestId> with loading/ok/status/error fields while successful payloads are exposed as data.<requestId>. RefreshButton is an installed runtime helper: it refreshes load queries by default; inside a successful manual result, requestId targets and reruns that active query with unchanged parameters. A bound Pagination should declare defaultValue={1}; resetKey={inputs.query} restores that default when its dependent scalar query changes. SubFetch without trigger="manual" runs automatically and reruns when bound params change, so never demand a hidden input, debounce callback, or raw event. When the scoped Request requires manual search, do not penalize the required re-trigger after query or page changes. A manual SubFetch synchronously hides its old result and returns to its trigger when its request ID, normalized parameters, or effective definition changes; it cannot display stale results under edited inputs or fetch the new parameters before another trigger. ActionButton supplies pending UI, native success/error notification, confirmation, and declared invalidation; do not demand duplicate local action state. Safe templates forbid local declarations and helper functions, so do not penalize a repeated short literal label array used for distinct enum fields as an avoidable missing abstraction. Every component in this already-validated template exists in the installed release. Do not penalize those documented facts. The widget has already passed Homarr's real schema and JSX analyzer, which proves syntax and component compatibility but does not prove API correctness, visual quality, usefulness, or accessibility.

 - Compare every requested capability with concrete manifest/JSX evidence. A missing or invented core capability is fatal and caps total at 79.
 - Judge whether the API design can actually reach the stated goal, including response paths, bindings, invalidation, and action safety.
 - Judge visual quality, not component count: hierarchy, density, whitespace, typography, restrained color, scanability, and avoidance of repetitive nested cards.
+- A purpose-specific asymmetric summary, divided hierarchy, responsive density, and restrained semantic accents can clear 75 without decorative chrome. Do not demand gradients, novelty, or a generic selected-row detail interaction.
 - Judge daily usefulness: information priority, interaction cost, refresh behavior, narrow-tile usability, and whether the widget is pleasant rather than demo-like.
+- A required manual search rerun is deliberate interaction, not daily-use friction. SubFetch owns failure and retry before its child renders; never demand an unreachable child error branch or a RefreshButton there.
 - Judge complexity discipline: penalize duplicate requests/options, unnecessary controls, excessive JSX, cleverness, and UI chrome that does not help the goal. Complexity must earn its place.
 - Recommend only interactions supported by the installed authoring contract. Do not suggest portals, modals, arbitrary event handlers, or other blocked capabilities. Prefer a responsive in-widget detail area when separation is useful.
 - A visually generic but valid widget should normally score below 75 for visualQuality. A widget that is attractive but inconvenient should score below 75 for dailyUsefulness.

+export const CUSTOM_WIDGET_ASSISTANT_POLICY = `Custom Widget work:
+- Use customWidget tools; never substitute prose.
+- Start with customWidget_getSkill. Do not load the full catalog. Load the compact schema reference once for a new manifest; skip it for a supplied valid v2 draft. Reuse loaded context with no arbitrary documentation or creativity cap. Lifecycle tools run one at a time and change the active phase.
+- Before previewing any authenticated source or mutation, load the security reference exactly once. Load runtime for manual interactions.
+- Plan capabilities; make one focused component search per widget job with customWidget_findComponents to prove presentation components exist. Batch interaction docs once with customWidget_getComponents, then validate. Failure reopens discovery; otherwise fetch only a missing capability/example.
+- For a coordinated set, research primary API documentation once; reuse facts, then finish each widget's validation, evidence, and persistence in order.
+- Read load queries via data.x/status.x and RefreshButton (never global status.loading/ok); keep sibling request data/errors independent. Manual queries use <SubFetch trigger="manual"> with params; SubFetch owns loading/error/retry and its child renders success/empty only. Result-local <RefreshButton requestId="x"> reruns unchanged params. SubFetch, ActionButton, and ToggleSwitch use a literal inherited requestId. Fixed query/body values stay primitives; $param is manual-only and load queries never contain $param. Reset dependent Pagination with defaultValue={1} and resetKey={inputs.query}. Wire every stateful control through bind/options into a request/helper; remove dead controls.
+- Samples/previews are exact response envelopes; preserve field meaning and paths. For { results: [...] }, render result.results. Never map the envelope as an array. Humanize numeric enums with indexed literal label arrays; omit absent numbers; format timestamps with documented Date helpers and label timezones.
+- Do not simplify because JSX is interpreted. Compose installed components with multiple sources, requests, options, choicesFrom, bound filters, charts, responsive details, manual queries, and safe actions; keep complexity purposeful.
+- Choose a divided list or responsive media grid. Compact headers; lead with one summary of responsive metrics, primary identity/state, quiet metadata/actions. Base artwork fills its row and caps above xs; never combine full-width media and nowrap. One primary badge, secondary state text. Avoid row-card walls, fixed columns, badge dumps, decorative copy.
+- A template is one JSX expression: no declarations, const/let, new, or statement-bodied callbacks. Draft templateLines; call customWidget_validateTemplate. Never shadow reserved roots data/status/options/inputs; use named Icon/TablerIcon, never IconFoo. Fix unknown-prop warnings before preview with customWidget_getComponent once, then revalidate. Pass definition as a tool object, never serialized JSON, to customWidget_previewCreate for queries and actions that need evidence.
+- For each final preview, run every returned query and every relevant simulated action; inspect shape, confirmation, permission, params, and invalidation. Use the journal only for routing.
+- After evidence, compare requested capabilities. For a JSX-only flaw, validate one response-driven correction; call customWidget_previewReviseTemplate: it inherits the manifest and resets evidence. Use a fresh previewCreate only when sources, requests, or options change—a material definition change. Do not reopen discovery or add optional polish. Retest every returned query and action; never revise a byte-identical template.
+- Persist through customWidget_createFromPreview so the definition is not streamed again; use customWidget_create only without a preview.
+- Never expose credentials or claim an operation succeeded before its tool result. Include preview/management links.`;
 
-Make one documentation tool call at a time. Never issue batched customWidget_getComponent calls, speculate about components, or walk the catalog. If preview evidence requires a definition change, restart at step 4 with the revised complete definition. The live resources are authoritative for this Homarr release.
+export const CUSTOM_WIDGET_MCP_AUTHORING_PROMPT = `Author one Homarr Custom JSX v2 widget or a coordinated set through the complete tool lifecycle.
 
-Keep the documentation phase bounded. Fetch at most eight named component documents before the first validation, or at most four after loading a complete example. Fetch another component only to resolve a concrete validation issue or missing interaction; never walk the catalog component-by-component. Move promptly from the smallest sufficient documentation set to a complete customWidget_validate call.
+${CUSTOM_WIDGET_ASSISTANT_POLICY}
 
-Construct one credential-free definition. Supply required manual parameters to preview queries, inspect the real response shape and HTTP status, and open or provide the returned previewPath for visual review. Use customWidget_create only when no reusable preview session exists. Prefer templateLines over a JSON-escaped template string for multiline JSX in validate and preview tool inputs.
-
-Do not claim a query works when it has not returned a successful preview response. Configure deployment-specific source URLs and request credentials through Homarr when needed; never repeat plaintext. Use simulated preview actions unless the user explicitly enables live preview actions.
-
-Treat preview data as the binding contract: render every core requested field, guard optional arrays and nested values before indexing, and do not silently drop returned items. Show timestamps as concise human-readable absolute dates and times; do not compute relative time with Date, Date.now, or Date.parse unless the live docs provide a safe helper. Give recoverable load errors and empty states a clear refresh or retry path.
-
-Use the lean keyed sources, requests, and options contract. Bind saved values directly with $option and invocation values with $param. Load queries cannot use $param. Keep the design responsive, accessible, theme-safe, loading-aware, empty-aware, and error-aware.
-
-Create distinctive polish with one restrained accent for decorative chrome, while operational, degraded, and down states retain distinct semantic colors. Use clear surface contrast and purposeful typography rather than decorative gradients or excessive nested cards. Do not wrap every metric or service row in Paper or Card. Prefer one dominant surface with clearly separated service rows, a one-column compact narrow layout, and an intentionally more spacious wide layout. Label standalone icons for assistive technology or pair them with visible text.
-
-Make initial states actionable with an example, useful hint, or clear next step. Use wrapping groups for variable-length labels and values on narrow tiles. Do not use an unlabeled decorative icon as an empty state.
-
-Use Workshop search/get/install when the user asks for an existing community widget. After installation, configure self-hosted source URLs and credentials with the dedicated source configuration tool or a secure user configuration request.`;
+Use simulated preview actions unless the user explicitly enables live actions. Persist through the tools; do not merely print a manifest.`;

An action defaults to manual and modify permission. DELETE uses full permission and confirmation. Do not use \`load: false\`.
 
 Use stable real URLs for public APIs and clear suggested URLs for self-hosted services. Homarr collects the installer's server URL, network scope, and credentials as source setup; credentials remain outside the manifest.
 
-Paths use \`{option:name}\` and \`{param:name}\`. Query/body data uses \`{ "$option": "name" }\` and \`{ "$param": "name" }\`. Load queries cannot use params. Runtime parameter names and primitive values are inferred from references.

 </SubFetch>
 \`\`\`
 
-\`SubFetch\` with \`trigger="manual"\` renders its own load button. To make a card or image launch the request, pass that node through \`triggerContent\` and provide \`triggerAriaLabel\`; Homarr supplies the click and keyboard behavior. Its optional second callback argument contains \`{ ok, status, statusText, loading: false }\`; loading and request failures are rendered by \`SubFetch\` before the callback runs. Do not author \`onClick\` or a fetch callback.
+Manual queries require \`trigger: "manual"\` on request and \`SubFetch\`; otherwise they run automatically. \`triggerContent\` with \`triggerAriaLabel\` makes custom content the launcher. \`SubFetch\` owns loading/error/retry; its child receives success plus \`{ ok, status, statusText, loading: false }\`. Never author \`onClick\` or fetch callbacks.
 
-Use expression callbacks for supported collection methods and trusted slots. Do not use callback blocks, IIFEs, authored recursion, or raw events. Bounded regex literals work only with safe string matching/replacement operations.
+\`SubFetch\`, \`ActionButton\`, and \`ToggleSwitch\` need literal \`requestId\`; validation rejects missing/computed IDs.
+
+Inside a successful manual result, \`<RefreshButton requestId="search" label="Run again" />\` reruns the same parameters.
+
+When a manual SubFetch request ID, parameters, or effective definition changes, Homarr immediately hides its prior result and returns to the trigger. It cannot fetch the new parameters until the user triggers it again.
+
+The \`SubFetch\` callback receives the entire JSON response exactly as previewed. If the response is \`{ "results": [...] }\`, render and map \`result.results\`; never map the envelope itself. Trace every rendered field from the preview response before persistence.
+
+Format timestamps with safe static helpers; never use \`new Date\`. Never invent a formatter component. Use \`Date.toLocaleString(value, "en-US", "UTC")\` plus a visible \`UTC\` label. Also available: \`Date.toISOString\`, \`Date.toLocaleDateString\`, and \`Date.toLocaleTimeString\`.
+
+For compact numeric enums, index a literal label array with a fallback:
+
+\`\`\`jsx
+<Text>{["Unknown", "Pending", "Ready"][(item.status ?? 1) - 1] ?? "Unknown"}</Text>
+\`\`\`
+
+Every stateful control must use \`bind\`, and its \`inputs.<name>\` value must feed a supported request/helper when it is meant to change remote data. For dependent pagination, declare \`defaultValue={1}\` and use \`resetKey={inputs.search}\` to restore page 1 when the query changes. If a control cannot affect the workflow through a binding, option, or runtime helper, render concise context instead of a dead control.
+
+Callback parameters must not shadow the reserved roots \`data\`, \`status\`, \`options\`, or \`inputs\`. Use \`<Icon name="refresh" />\` or \`<TablerIcon name="refresh" />\`; never invent components such as \`<IconFoo />\`.
+
+Use expression callbacks for supported collections and trusted slots. No callback blocks, IIFEs, authored recursion, or raw events. Regex is limited to safe string operations.

 # Homarr Custom Widget
 
-Author one widget at a time. When connected to Homarr, retrieve \`homarr://custom-widgets/schema\` and only the component resources needed for the design. The live resources are authoritative for the installed release.
+Author one widget or a coordinated set of widgets. Load only needed release-matched context. Run lifecycle tools alone; independent reads may run together. For a set, research once and finish each widget's validation, evidence, and persistence before the next.
 
-Keep documentation retrieval targeted: fetch at most eight named component documents before the first validation, or at most four after loading a complete example. Fetch another component only when a validation issue or a concrete missing interaction requires it; never load the catalog component-by-component.
+1. Read primary API documentation. Use web search when documentation is not supplied or may have changed.
+2. Create credential-free definitions with keyed \`sources\`, \`requests\`, optional \`options\`, and safe JSX \`template\`.
+3. While drafting, use \`customWidget_validateTemplate\` for focused JSX diagnostics without resending the manifest.
+4. Send the definition once to \`customWidget_previewCreate\` and test its queries/actions. For a JSX-only fix, validate, call \`customWidget_previewReviseTemplate\` with its session, and retest; it inherits the manifest and resets evidence. Create a preview only for source/request/option changes.
+5. Configure deployment-specific source URLs and credentials through Homarr; never repeat plaintext.
+6. Persist each exact final tested preview with \`customWidget_createFromPreview\`. Do not resend a large definition through \`customWidget_create\` when a preview session is available.

-5. Save only after narrow/wide, light/dark, loading, empty, error, and success states work. When connected through MCP, persist the exact final tested preview with \`customWidget_createFromPreview\`; do not resend a large template through \`customWidget_create\` unless no preview session is available.
+Treat a supplied sample or successful preview response as the binding contract. Render every core requested field, guard optional arrays and nested values before indexing, and do not silently drop returned items. Humanize numeric enums with indexed literal label arrays, omit absent numeric values instead of inventing zero, and label timestamp timezones. Give recoverable load errors and empty states a clear refresh or retry path.

+For a bound control that depends on another input, declare its default and set \`resetKey\` to that scalar dependency. For example, \`<Pagination bind="page" defaultValue={1} resetKey={inputs.search} />\` restores page 1 when a search changes without fetching by itself.
 
-\`SubFetch\` with \`trigger="manual"\` renders its own load button. Pass a card or image through \`triggerContent\` with \`triggerAriaLabel\` when that content should launch the request. Its callback is \`(result, meta)\`; never author \`onClick\` or a fetch callback.

Use \`Icon\` or \`TablerIcon\` with a \`name\`; never invent an \`IconFoo\` component.
 
-Use standard Mantine compound names and deliberate visual hierarchy, spacing, restrained semantic color, and responsive layouts. Avoid excessive nested cards.
+Plan capabilities. Use one \`customWidget_findComponents\` search per job. Batch selected non-obvious binding or interaction documentation with \`customWidget_getComponents\`; reserve \`customWidget_getComponent\` for one unknown-prop repair. Failed validation reopens discovery; otherwise search only for a missing capability. The full catalog is for broad exploration; load at most one example. Context never limits composition. Prefer clear hierarchy, responsive grids, divided lists, and aligned actions over nested row cards.
 
-Aim for distinctive polish without decorative gradients or fragile custom styling: use one semantic accent, clear surface contrast, purposeful typography, and compact rows that remain scannable in narrow tiles. Give standalone icons an accessible label or pair them with visible text.
+Do not simplify a useful workflow merely because the template is interpreted. Freely compose any supported installed components with multiple sources, requests, options, \`choicesFrom\`, bound filters, charts, responsive detail areas, manual queries, and safe actions when they improve the user's job. Complexity must remain purposeful rather than decorative.
 
-Make initial states actionable with an example, useful hint, or clear next step. Use wrapping groups for variable-length labels and values on narrow tiles. Do not use an unlabeled decorative icon as an empty state.
+Polish with a divided list or responsive media grid. Make one metric/action asymmetrically primary; keep headers compact, identity/state clear, metadata quiet, and one badge. At base artwork fills its row and caps above xs; never combine full-width media and nowrap.
+
+Make initial states actionable and wrap variable labels/values on narrow tiles. Do not use an unlabeled decorative icon as an empty state.
 
 Do not use imports, hooks, refs, raw HTML, raw event callbacks, browser requests, arbitrary functions, eval, bigint, npm packages, authored statement blocks, IIFEs, or recursion. Do not pretend MCP tools exist in an offline chat session.
 
-To install an existing widget, use \`customWidget_workshopSearch\`, inspect it with \`customWidget_workshopGet\`, then use \`customWidget_workshopInstall\`. Configure each self-hosted source afterward with \`customWidget_sourceConfigure\`, or call \`customWidget_configurationRequestUser\` so the user can enter the server URL and credentials directly in Homarr.
+For a community widget, use \`customWidget_workshopSearch\`, \`customWidget_workshopGet\`, then \`customWidget_workshopInstall\`; configure its source securely. Preview configuration expires, so create before persisting configuration.
 
-Preview-scoped configuration expires with the preview. To persist user-entered values for a new widget, create the widget first, request configuration for its definition ID, then create a final preview with that definition ID so Homarr loads the stored credentials.
+Reference routing:
 
-When this skill is installed from the repository, optional offline details are in \`references/schema.md\`, \`references/runtime.md\`, and \`references/security.md\`. MCP-only clients should use the live Homarr resources instead.
+- Load \`schema\` once before a new manifest; otherwise only for concrete request or option ambiguity.
+- Load \`runtime\` for bound inputs, manual queries, actions, or other interaction.
+- Load \`security\` once for any authenticated source or mutation, or to resolve a URL or interpreter limitation.
+
+Repository installations expose these as files under \`references/\`. MCP clients can call \`customWidget_getReference\` or read \`homarr://custom-widgets/references/{name}\` instead of loading every reference.

+Use release-matched tools and load only context required by the design. Research primary API documentation once. For each widget, validate JSX independently with \`customWidget_validateTemplate\`, create one coherent preview, test every returned query and simulated action, then persist that exact preview. For a response-driven JSX-only correction, validate it and call \`customWidget_previewReviseTemplate\`; it inherits the manifest, resets evidence, and avoids resending sources, requests, or options. Complete one widget before drafting the next in a coordinated set.
+
+Before drafting, map every requested capability to a rendered field, bound control, or safe action. Give each widget a purpose-specific visual signature: asymmetric priority metric/action, quieter supporting metrics, compact header, accurate status language, resolved and accessible imagery, responsive details, and actionable initial, loading, empty, error, and success states. Avoid dead controls, raw relative artwork paths, and repetitive nested cards.

+Context routing:
+
+- \`schema\`: once for a new manifest; otherwise only for request or option ambiguity.

+- \`security\`: exactly once for authenticated sources, mutations, URLs, or interpreter constraints.
