# Assistant
Administrators can configure the instance-wide AI assistant from **Management → Assistant**.
It is available to signed-in users from the user menu, with `Shift + A`, and from the
`Cmd/Ctrl + K` command menu. **Ask Homarr Assistant** is always available as a local result in the default
search. Selecting it with an existing query sends that query in the background; selecting it without a
query turns the command-menu search field into a prompt composer. Press
`Enter` to send the prompt in the background without opening the conversation. The search field receives
focus whenever the command menu opens, including when it is opened by an assistant tool. Sending from the
command menu preserves any draft in the expanded conversation. The local result is temporarily disabled while
the assistant is responding or waiting for an approval.
While a response is running, a compact activity bar appears at the bottom of the page and the user-menu
avatar shows a thinking indicator. The activity bar can be opened to follow the response. Completed
responses add an unread count to the user menu until they are opened or dismissed. The expanded
conversation has a minimize action that returns it to the activity bar without interrupting a response.
Its adjacent close action hides the panel without leaving an activity bar behind. Both window actions use
subtle buttons with an icon, tooltip, and accessible label.
The transcript follows streamed output while it is already at the bottom, including fast responses. Scrolling
up releases that follow state until **Scroll to latest** is selected or the user returns to the bottom.
`Shift + A` opens the compact conversation panel directly. The shortcut is ignored while typing in text
fields, selectors, and editable content.
The **Assistant** board widget embeds the same persisted conversation and full interaction surface directly
on a dashboard. By default it follows the current conversation. Widget settings can instead pin a specific
conversation; the conversation picker stays hidden until **Pinned conversation** is selected.
The Shift+A panel is non-modal: opening it focuses its composer, but it does not capture focus from the board.
Users can continue typing in an Assistant widget or interacting with other dashboard controls while the panel
is open. Every visible assistant surface keeps its own draft, attachment list, selection, and focus while sharing
the same persisted conversation. Switching conversations restores the draft that belongs to that surface and
conversation instead of copying text into another widget or the floating panel.
When the assistant is unavailable, its command-menu result remains visible but disabled and explains that
an administrator must configure and enable it.
The assistant uses the assistant-ui runtime for **AI SDK v7**. Homarr tracks the newest mutually compatible
package set permitted by its supply-chain release-age policy. Persisted message rows can still report the upstream
codec name `ai-sdk/v6`; assistant-ui's current v7 adapter deliberately retains that identifier for its compatible
UI-message wire format. It does not mean the application is running AI SDK v6.
## Configure a model provider
Homarr includes presets for OpenRouter, OpenAI, Anthropic Claude, Google Gemini, xAI, Groq, Mistral AI,
DeepSeek, Together AI, Ollama, and LM Studio. Provider icons make the presets easy to identify. A custom
preset connects any other service that implements the OpenAI Chat Completions API.
The provider list also shows **Homarr — Coming soon** as a disabled option.
The management page presents setup as three compact sections: provider and endpoint, credentials, then
model and availability. A status summary at the top shows whether the connection is ready, whether a key
is protected, and which model is selected. Redundant active-state badges are omitted when the setup is ready.
1. Choose a provider preset or **Custom endpoint**, then confirm the API base URL. It usually ends in `/v1`.
2. Add an API key if the service requires bearer authentication. Additional authentication or routing
headers are available in the collapsed advanced section.
3. Save the provider connection.
4. Refresh the model list and select a discovered model. Homarr displays the friendly model name but
stores and sends the provider's exact model ID. Context-window sizes use compact labels such as `1M`.
5. Enable the assistant and save the configuration.
The model discovery path defaults to `/models` and is appended to the API base URL. Leave it blank when
the service does not expose model discovery. A manual model ID can still be used when discovery is
disabled, unavailable, or returns no models.
API keys and additional header values are encrypted in the Homarr database. They are decrypted only on
the server for discovery and model requests, and they are never returned to the browser. Changing the
provider or base URL clears existing credentials. This prevents credentials for one service from being sent
to another endpoint.
When a key is already stored, the page shows its protected state instead of an ambiguous empty password
field. Removing the API key requires explicit confirmation. Save that removal before entering and saving a
different key.
:::info Container networking
For a containerized Homarr installation, `localhost` refers to the Homarr container. Use a resolvable
container name, internal DNS name, or host gateway address to reach Ollama, LM Studio, or another local
model server.
:::
The configured endpoint must support streaming Chat Completions and structured tool calls for the full
assistant experience. Model discovery alone does not guarantee tool support, except when OpenRouter
explicitly advertises the model's `tools` capability.
OpenRouter web search is an opt-in option in the model section. It registers OpenRouter's model-callable
[`openrouter:web_search` server tool](https://openrouter.ai/docs/guides/features/server-tools/web-search)
alongside Homarr's tools, so OpenRouter performs each search without
exposing the stored credential to the browser. The model decides when live research is needed and can use the
grounded results and source links in responses or dashboard notes. Homarr limits each assistant request to
three searches with five results per search. OpenRouter charges web-search usage separately from model tokens.
Completed responses show a compact web-search activity card when OpenRouter reports search usage. OpenRouter
does not expose these server-side searches as ordinary client-executed tool calls, so Homarr shows the reported
search count and the safe title and URL from each returned `url_citation` annotation instead. Citation excerpts
stay in the provider response and are not persisted in the activity card.
The option is also available for custom endpoints that forward OpenRouter's server-tools request format. This
supports OpenRouter proxies, including the future Homarr Router provider. Leave it disabled for ordinary
OpenAI-compatible endpoints because the `openrouter:*` tool type is not part of the standard OpenAI API.
The Claude preset uses Anthropic's OpenAI SDK compatibility layer. Anthropic describes that layer as
suited to testing and comparison rather than as its full native API; unsupported OpenAI fields may be
ignored. Streaming responses and tool calls are supported, which are the capabilities Homarr Assistant
uses. Choose OpenRouter or another provider when you prefer a provider-neutral production endpoint.
## Conversations and tools
Conversations and messages are stored per user in the Homarr database. The assistant stays out of the
page layout until it is opened. Users can start, revisit, and delete conversations from the
conversation menu in the floating panel.
Messages support copy, edit-and-resend, response regeneration and branch navigation, Markdown export,
and helpful/not-helpful feedback. The conversation menu also provides a compact export action beside delete for
each conversation. Its debugging-oriented Markdown includes every stored user, assistant, reasoning, tool, error,
branch-parent, and server-metadata record while redacting secret-looking fields and embedded attachment data.
The per-response export uses the same tool-aware format instead of assistant-ui's text-only copy representation.
Selecting text in a message exposes a quote action that carries the selected passage into the next prompt.
Files returned by a compatible model can be downloaded directly from the message.
Assistant responses render GitHub-flavored Markdown, including headings, links, lists, task lists, tables,
quotes, inline code, and fenced code blocks. Line breaks are preserved, and Homarr repairs common streamed
responses where a provider returns escaped line breaks or places a bold-label list on one line.
Completed fenced code blocks use language-aware syntax highlighting; a streaming block stays plain until its
content is stable. Safe same-origin links are prefetched and use client-side navigation, so opening a returned
preview, editor, board, or other Homarr item does not unload the assistant. External links keep their normal
external-browser behavior.
Fenced `mermaid` blocks render as diagrams in the current color scheme using Mermaid's strict security mode;
invalid diagrams fall back to their source instead of breaking the response.
When Homarr's icon search returns an image URL, visual result tables render that actual icon in a compact
image column instead of substituting an emoji. Assistant-provided Markdown images accept safe relative,
HTTP, and HTTPS sources and load without forwarding the Homarr page as the referrer. Image message parts
render through assistant-ui's image primitive in a bounded responsive preview with an accessible loading state,
a filename caption when available, and an in-place retry when the source fails.
Images up to 1 MB and text, Markdown, CSV, HTML, XML, or JSON documents up to 350 KB can be attached by
using the paperclip, dropping files onto the composer, or pasting an image with `Cmd/Ctrl + V`. Attachment
previews stay local to the composer where they were added and show upload state, file type, and a removable image
thumbnail or document tile. A request can contain up to five attachments.
Image understanding depends on the selected model; document text is extracted locally by Homarr and sent
as part of the prompt.
Type `@` in the composer to add permission-checked context. The nested menu contains apps, integrations,
boards, widgets, and tools available to the current user. Homarr validates every referenced ID again on
the server before adding it to the model context. Selected references appear as compact, typed pills in the
composer and sent message, while preserving assistant-ui's underlying directive syntax for the model. When the
assistant cites one of those references in its own response, Homarr renders the same typed pill and uses the
stored app or integration icon when one is available. Type `/`
for common prompt shortcuts. Both menus support keyboard navigation and keep the active result visible while
moving through long lists. The selector below the composer combines searchable, provider-grouped models with
their description, context size and image-input capability, plus the thinking-level control. Model selection is
stored on the conversation after a completed request. Thinking mode can be left on **Auto**, disabled, or set
from minimal through high; explicit levels are sent using the AI SDK's provider-neutral reasoning setting and
still depend on support from the chosen model and endpoint. Reasoning text is shown live when the provider streams
it through assistant-ui's grouped-parts and chain-of-thought primitives. The compact **Thinking** trace groups
adjacent reasoning with ordinary tool calls, shows each tool's status, duration and safe human-readable target,
and expands raw input, output and result previews only on request. Approval and question tools remain full-width
outside the trace. The disclosure renders Markdown, can be opened or closed without interrupting the response,
and keeps the user's collapsed state when another message starts. A compact dot matrix distinguishes an initial
thinking pass from response streaming and settles into waiting, success, or error states in the minimized activity
bar. The state always keeps its text label, and the animation is disabled when the operating system requests
reduced motion.
A circular context ring beside the model selector gives a quick glance at cumulative conversation usage without
expanding the composer toolbar. Its accessible label includes cumulative tokens and cost when available, while
its popover keeps the latest complete context reading as a new response starts and lists every request
turn with its model, provider, input, output, cached-input and reasoning tokens, context use, duration, speed,
agent steps, routing details, and cost when reported. Before usage is available, the control remains a compact
ring instead of showing a redundant missing-data label. Closing and reopening the popover reads persisted
conversation metadata instead of resetting the display to zero. A larger ring inside the popover breaks the latest
reported context into used, remaining and total capacity plus input, cached-input, output and reasoning tokens.
Each assistant response places a small provider logo in the same stable action toolbar as copy, export,
feedback, and regenerate. Hovering the logo shows the provider, exact model, timing, throughput, and cost without
adding another metadata row to the transcript. Branch navigation occupies its own adjacent group, so switching
between response versions never pushes the response actions off-screen.
OpenRouter responses request inline usage and routing metadata. Opening detailed turn data also loads the
server-side generation record for its model steps and briefly polls while OpenRouter finishes processing it.
The details separate Homarr's end-to-end timing from OpenRouter's provider latency, generation time, and provider
throughput, and can include normalized and native token counts, moderation latency, cache discount, fallback count,
service tier, data region, BYOK status, routed provider, generation identifier, exact cost, and upstream inference
cost. Provider credentials remain server-side; the browser can request only generation identifiers already stored
on a conversation owned by the signed-in user and signed by the Homarr server for that user and conversation.
Successful generation lookups are cached briefly so polling and multi-step requests do not repeatedly query
OpenRouter for the same record.
When a provider omits cost but model discovery includes prompt and completion pricing, Homarr labels the
calculated value as estimated. Missing provider data is shown as not reported rather than inferred.
The assistant can use the same internal tool definitions as the [Homarr MCP server](./mcp).
Each tool call runs as the signed-in user, so normal Homarr permission checks still apply. Read-only
procedures can run during the agent loop. Mutating procedures require an explicit approval in the
conversation before they execute. The approval appears as a large **Approve and run** or **Deny** action;
the assistant does not require a second typed confirmation first. Tool cards expose their status, timing,
validated input, result, and error state without flooding the conversation with raw JSON by default.
Common collection and widget results are summarized inline as compact responsive cards, while the full
structured result remains available in the tool card details. Icon searches show the returned image variants,
file formats, and repositories instead of the size of the complete icon catalog. Their trace uses a readable
activity such as **Looking for “homarr” icons** instead of exposing the internal MCP procedure name.
Large tool-driven requests can use up to 32 agent steps and a larger response budget within one request, so
multi-item dashboard changes normally finish without requiring a follow-up “Continue” message. OpenRouter calls
Homarr tools sequentially to prevent routed models from interleaving or truncating parallel JSON arguments, while
every mutation still pauses for its normal approval. A safely recoverable truncated icon-search object is repaired
before validation; incomplete search strings and all mutation inputs are never guessed.
Homarr also normalizes internal tool results to the model's JSON-compatible message format before continuing an
agent loop. Rich server values such as dates cannot invalidate the next model step, and an interrupted tool call
without a result is omitted when the conversation resumes instead of making the entire prompt fail.
The assistant can create a formatted dashboard note by adding a **Notebook** widget. Ask it for a note with
headings, lists, tasks, links, emphasis, tables, or images; it generates compatible rich-text content, shows
the native widget configuration form and standard mutation approval, then places the widget in the next
available dashboard position. The generated content is retained even though the Notebook content field is
normally hidden from widget settings.
Automatic placement checks every responsive layout and treats both widgets and complete container footprints
as occupied. New assistant-created items use the first free position in the main canvas instead of overlapping
existing content or being placed in a gutter.
Every assistant-created dashboard widget now passes through Homarr's native widget editor before it is added.
The form fills widget defaults, validates widget-specific options, and only offers compatible integrations that
the current user can use. Required integrations cannot be left empty, single-integration widgets cannot receive
multiple integrations, and the reviewed values are passed unchanged into the final approval-gated mutation.
Custom-widget tools let an administrator list, inspect, create, and update definitions. The custom-widget
form's **Design with AI** action sends a focused request into the current conversation, where the assistant
can propose the matching mutation and use the same approval controls. Existing stored secret values are
reported only as configured/not configured and are preserved on update unless replacements are explicitly
provided. For Custom Widget requests, Homarr lazily adds the complete installed skill, all bundled schema,
runtime and security references, and the current JSON Schema to the trusted authoring context. This avoids an
extra provider round trip for the large `customWidget_getSkill` and `customWidget_schema` results. If the model
discovers the Custom Widget workflow mid-response, Homarr promotes the same resources before its next step and
removes the now-redundant resource calls from provider history. Multiline JSX uses `templateLines` to avoid fragile
streamed JSON escaping. Custom Widget authoring tools are mandatory: the assistant validates the complete candidate,
creates a preview from that exact version, executes every returned preview query, checks the actual HTTP status and
response shape, and repeats the entire validation and preview sequence after any material JSX, request, source, option,
or binding change. It only reports a widget as validated, working, created, or placed when the corresponding tool result
proves that checkpoint. Large widgets are saved from the exact final tested preview session, so the approved create step
does not stream the complete JSX a second time. When the request already names a board, that board is carried into the
create result and placement continues without asking the user to select it again. Preview and saved-definition results
include safe Homarr paths that open in the assistant without a page reload. When placement is still a choice, the
assistant uses the structured question UI instead of ending with a prose question.
The authoring phase limits broad component-document retrieval and then moves into validation with the smallest useful
reference set. Supplied samples and successful preview responses are treated as binding contracts: the assistant is
instructed to render the requested fields, guard optional nested data, preserve every returned item, expose freshness
when timestamps are available, and provide a refresh path for recoverable empty or error states.
The shield control in the conversation header can enable automatic approvals for the current conversation.
While enabled, Homarr accepts every affirmative approval step as it arrives: protected mutations are approved,
presented app details and board changes are used, and structured questions with an explicitly categorized
**Confirm** answer choose that answer. Neutral choices such as selecting a board still wait for input because
they do not have a safe affirmative default. Automatic approvals turn off when you switch conversations, and
the shared approval tracker prevents the same call from being handled twice when both a board widget and the
floating assistant are visible.
When the assistant genuinely needs missing information or a choice, it can pause with a structured
question. Each proposed answer is visibly categorized as **Confirm**, **Decline**, or **Option**, so the effect
of automatic approval is unambiguous. Users can select one of the proposed answers or choose **Other** and
enter their own response. While a question is unanswered, its controls stay in a dedicated area immediately
above the composer instead of requiring the user to find the tool call in the transcript. The question temporarily
uses the available conversation body, with its own scrolling when necessary, rather than squeezing a long option
list into a short dock beside part of the transcript. The answered choice then remains in the conversation history.
Submitting the answer resumes the same agent run automatically. The minimized activity bar shows the
question or approval that needs attention and opens directly back to the request. While an answer, app
form, or mutation approval is pending, the composer preserves its draft but does not replace the pending
tool call with a new message. If the provider stops before an interactive tool supplies complete arguments,
Homarr replaces the loading state with an explicit error and confirms that no change was made.
App creation uses Homarr's native app form inside the conversation. The form reuses the local icon picker,
including automatic matching and searches through the `icon.findIcons` procedure, before the final
`app.create` approval is requested. App fields are filled only after the complete tool input has arrived, so
streaming partial arguments cannot replace the proposed values with empty fields. The model is instructed not
to invent external icon CDN URLs.
Board appearance changes use a similar review flow. The assistant first reads the board's current settings,
including its complete custom stylesheet, and then opens an editable form with Custom CSS, Appearance,
Background, and General tabs. The form highlights how many fields were proposed, preserves settings the
assistant did not change, and returns only values that differ from the current board. Custom CSS can be
copied or restored before continuing, and Homarr warns when it contains an imported stylesheet or remote
resource URL. Continuing from the form opens the normal mutation approval before anything is saved.
Ask for changes such as “make the cards denser on my Home board,” “add a mobile CSS rule without removing
my existing styles,” or “change the board colors and disable app status checks.” The current user must have
modify permission on the selected board. The empty conversation includes an **Improve a dashboard** starter,
and `/style` prepares the same guided workflow from the composer.
Homarr also exposes a small set of browser-only actions to the assistant. These actions can navigate to
safe internal routes, refresh the current view, and open Homarr interfaces such as the command menu and media request search.
They never receive provider credentials and cannot navigate to arbitrary external URLs.
After an approved mutation completes, Homarr automatically refetches active page and dashboard data so
board items, settings, custom CSS, apps, and other visible results update without a full browser reload.
The refresh action in the conversation header performs the same safe refetch manually. It keeps the
conversation open while refreshing both client queries and server-rendered route data.

1. Get the prompt, live schema, and component catalog.
2. Read the external API documentation.
3. Build one definition.

5. Create a preview session.
6. Test the queries and actions.
7. Open the preview URL with browser tools.
8. Inspect the redacted journal and revise the local candidate until it is valid.
9. Create the widget, including any source URLs and credentials the user already supplied.
10. Otherwise, ask the user to configure the saved definition with the ten-minute Homarr source-setup URL.
11. Create a final preview with the saved definition ID so Homarr loads its stored credentials, then test it again.
12. Update the saved definition if the final verification finds a problem.
13. Repeat the procedure for the next widget.
1. Load `customWidget_getSkill`, then get the prompt and live schema.
2. Call `customWidget_getComponentCatalog`, followed by `customWidget_getComponent` for only the relevant installed
components and `customWidget_getExample` when one catalog example matches the interaction pattern. If shared props
are needed, collect their catalog names and call `customWidget_getSharedProps` once for that set.
3. Read the external API documentation.
4. Build one definition, using `templateLines` for multiline JSX tool input.
5. Validate the definition without saving it and repair every reported issue.
6. Create a preview session.
7. Run `customWidget_previewQuery` for every query returned by the preview and inspect its actual status and data shape.
8. Test relevant actions in simulation mode.
9. Open the returned preview path with browser tools.
10. Inspect the redacted journal and revise the local candidate until validation, data, and rendering all work.
11. Create the widget, including any source URLs and credentials the user already supplied.
12. Open its returned management path, and use a structured question when the user must choose whether to place it on a board.
13. Otherwise, ask the user to configure the saved definition with the ten-minute Homarr source-setup URL.
14. Create a final preview with the saved definition ID so Homarr loads its stored credentials, then test it again.
15. Update the saved definition if the final verification finds a problem. `customWidget_update` also accepts
`templateLines` for multiline JSX without resetting omitted options.
16. Repeat the procedure for the next widget.
Successful validation returns a compact summary instead of echoing the full widget and template. Preview creation
returns its session, links, and query checklist without repeating the submitted definition. Keep the candidate locally

### Design with AI
The **Design with AI** action is available while creating or editing a custom widget. Describe what the widget should show and, when [Homarr Assistant](../assistant) is enabled, send the request directly from the form. The assistant receives the widget schema, current non-secret configuration, and latest test response, then proposes the matching create or update tool for your approval.
Run **Test** first when possible so the prompt includes the endpoint's real response shape. Saved secrets are never added to the prompt. **Copy to clipboard** remains available when the Assistant is disabled or when you prefer another AI service.

Homarr exposes a [Model Context Protocol](https://modelcontextprotocol.io) server at `/api/mcp/mcp`, enabling AI assistants like Claude, Cursor, VS Code Copilot, and Claude Code to interact with your Homarr instance using natural language.
Homarr exposes a [Model Context Protocol](https://modelcontextprotocol.io) server at `/api/mcp`, enabling AI assistants like Claude, Cursor, VS Code Copilot, and Claude Code to interact with your Homarr instance using natural language.
The endpoint implements the stateless MCP 2026-07-28 protocol and accepts 2025 Streamable HTTP clients through a
stateless compatibility path. It does not create protocol sessions or require sticky sessions. Homarr creates the
server and extracts its tools only after an authenticated request reaches the route. The previous `/api/mcp/mcp` URL
remains available as a compatibility alias, but new clients should always use `/api/mcp`.
With MCP, you can ask your AI assistant to manage apps, integrations, users, boards, Docker containers, media servers, DNS settings, and more - all through Homarr's existing tRPC API, now exposed as 50+ AI-callable tools.
The optional [Homarr Assistant](./assistant) uses these same tool definitions internally.
Unlike external MCP clients, it uses the current Homarr session directly and asks for in-conversation
approval before running mutating procedures.

import { AddingWidget } from "@site/src/components/widgets/adding";
import { WidgetConfig } from "@site/src/components/widgets/configuration";
import { WidgetHeader } from "@site/src/components/widgets/header";
import { assistantWidget } from ".";
<WidgetHeader widget={assistantWidget} categories={["Productivity"]} />
The Assistant widget brings the same conversation available from the user menu and command menu onto a
board. Messages, conversations, tool calls, approvals, files, mentions, model controls, reasoning controls,
usage details, and response actions remain synchronized with the app-wide assistant.
The assistant must be enabled by an administrator in **Management → Assistant**. Signed-out users and users
on an instance without an enabled model see an unavailable state instead of a broken composer.
### Adding the widget
<AddingWidget />
The default widget size is ten columns by four rows and automatically fits boards with fewer columns. Controls
and labels condense as the widget becomes narrower, while the conversation remains scrollable and usable on
touch devices. When a board layout does not provide enough height for conversation controls, the widget shows
a compact **Open assistant** action instead of squeezing an unusable composer into the card. Increase its height
in that layout to keep the complete conversation inline.
### Configuration
<WidgetConfig configuration={assistantWidget.configuration} />
**Current conversation** follows whichever conversation is active in the user-menu panel, `Shift + A`, or
the command menu. This is the default and keeps every assistant entry point synchronized.
**Pinned conversation** reveals a searchable conversation selector. A pinned widget never changes the
active conversation silently: select **Open conversation** inside the widget before continuing that thread.
### Conversation features
- Create, switch, rename, and delete conversations.
- Send text and supported file or image attachments by picker, drag and drop, or image paste.
- Mention permitted apps, integrations, boards, widgets, and tools with `@`.
- Use `/` shortcuts for common dashboard tasks.
- Review tool calls, approve mutations, and answer structured assistant questions inline.
- Answer pending structured questions from the dock above the composer without scrolling through the conversation.
- Enable conversation-scoped automatic approvals from the shield control to approve protected mutations, use presented form details, and choose answers categorized as affirmative without individual clicks.
- Edit user messages and copy, regenerate, branch, quote, export, or rate responses.
- Inspect syntax-highlighted Markdown, sources, generated files, tool results, streaming chain-of-thought,
cumulative conversation usage, per-turn token and context use, timing, speed, provider routing, and cost.
- Change the model and reasoning effort for the active conversation.
- Refresh the current board from the conversation header. Approved mutations also refresh visible board data automatically.
The expanded assistant and board widget use the same persisted thread runtime. A response continues in the
background when the widget leaves the viewport or the expanded panel is minimized. Each visible surface keeps an
independent draft, attachments, selection, and focus, so typing in a board widget cannot move or overwrite the
floating panel composer.

"This action is protected by Homarr's native approval UI. When the user's request and the required inputs are clear, call this tool immediately. The tool call only requests approval; it does not execute until the user selects Approve and run. Never ask for confirmation in prose before calling it.";
export const customWidgetAssistantInstructions = `
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.`;

const assistantInstructions = `You are Homarr Assistant, embedded in the user's self-hosted Homarr dashboard.
Use the available Homarr tools whenever live instance data is needed. Never invent integrations, boards, apps, users, media, system status, or action results.
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.
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 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 call configure_board_settings with only the requested proposed changes. The user can edit the complete CSS and settings in Homarr's native form. Use its 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.
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.
## Key Concepts
**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 container IDs.
**"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.`;

**"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 container IDs.
**"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.`;
