app_errors
App errors
Grouped errors for an app, read live from its box: uncaught exceptions (with stack traces), silent 5xx responses and container crashes, grouped by fingerprint with count, first/last seen, the releases they occurred in and a sample route. Call with `error_id` to get one group with up to 3 sample events (message, stack, request). `since` is "1h", "24h" (default) or "7d". A group is resolved automatically once it stops occurring after a newer deploy. The fix loop: app_errors → app_errors(error_id) → read_file → write_files → deploy → status → app_errors again. Builders only.

app_metrics
App metrics
Request, resource and profiling metrics for an app from its box: request count, status mix (2xx/4xx/5xx), error rate, p50/p95/p99 latency, top routes by traffic, slowest and erroring routes, public vs signed-in traffic, cpu / memory / restarts / OOM, app.db + WAL size, healthy %, the last scheduled runs — and, for apps running with the Croft runtime, where the time goes: `breakdown` (average ms per request in the database, external calls and the app's own code), `top_routes_by_time`, `top_external` (hosts / connectors), `top_db` (statements — builders only) and `slowest` (traces; spans for builders). `window` is "1h", "24h" (default) or "7d"; `route` narrows to one route's breakdown and its slowest traces. Use it to answer "is the app healthy / slow / erroring?", "why is it slow?", and to check a fix after deploying.

deploy
Deploy
Commits, builds (Nixpacks), and deploys the app. Include a `message` — a short summary of what changed — which becomes this deploy's entry in the app's changelog (shown to the owner in the panel). Returns a deploy job id; the build runs in the background and its deploy_state moves through queued and running before it ends in succeeded or failed. The app is live only once the deploy has succeeded.

grant_connector
Grant connector to app
Gives one of your apps access to a connector. The app can then call the connector's operations. Note: this lets the app's code, and everyone the app is shared with, use the connector's credential. A connector an admin has marked admins-only can only be granted by an admin. Some connectors require admin approval: when a creator grants one of those, the grant is created as 'requested' and an owner/admin must approve it (they're emailed) before the app can use it — owners/admins granting it are approved automatically.

List the apps in this workspace whose data you can query read-only — the ones enabled for assistant access in the panel that you also have access to. Use describe_app_data to see an app's tables, then query_app_data to read it. This is how you answer questions about data held inside the workspace's apps — e.g. 'what stocks are in my portfolio app'.

Filter with `since` (e.g. "1h", "24h", "7d" or an RFC3339 time; default 24h), `grep` (case-insensitive regex or substring) and `level="error"` (stderr + error-looking lines).

propose_connector
Propose connector
Creates a new API connector as a DRAFT from the vendor's API docs: you supply the base URL, auth style, and an operations manifest. A workspace member (owner, admin, or creator) then opens the panel and adds the credential to activate it — the credential never passes through you. auth_style is bearer|header|query|basic; for header/query also give auth_param (the header/param name).

query_app_data
Query app data
Run a single READ-ONLY SQL query (SELECT/WITH only) against a queryable app's live SQLite database and get the rows back. Use describe_app_data first to learn the schema. Parameterise values via `params` with ? placeholders. Results are row-limited (max 500). Writes, PRAGMA and ATTACH are rejected. The app must be enabled for assistant access (in its settings) and you must have access to it; every query is audited.

request_public_data_access
Request public data access
For an app that has PUBLIC routes: request permission for it to use protected resources (its granted connectors AND other apps' shared data). Public apps are blocked from these by default so a public page can't leak workspace data. If you (the caller) are an owner or admin, this is granted immediately; if you're a creator it creates a request that an owner/admin approves (they're emailed). Call this when building a public app that also needs a connector or shared data.

set_app_icon
Set app icon
Set the app's icon, shown next to it in the Croft panel. Provide `svg`: complete, self-contained SVG markup for a simple, recognisable icon on a square canvas (use viewBox '0 0 64 64', bold shapes and a filled background, no <script>/<image>/external refs). It's stored and rendered as an image. Optional — without one the panel shows a generated fallback (a gradient tile + the app's initial), so only set an icon when you can make a genuinely representative one.

set_database_sharing
Set database sharing
Turns this app's database sharing on or off. Off by default (the database is private). When on, other apps in the same workspace may read AND write this app's SQLite database through Croft's internal broker at http://croft-data:8080/q/<this-app-name> (send {"sql":"…","params":[…]}), and this app is listed to other apps as reusable shared data. Pass read_only: true when this app's tables are maintained by a job (e.g. a sync from an external system) so other apps get a READ-ONLY handle and can't write rows the next run would overwrite. By default apps that have PUBLIC routes cannot read this shared data (a leak guard); an owner/admin can pass allow_public: true to let public apps read it too. Turn sharing on for an app whose data other apps should reuse — e.g. a CRM's contacts list that an invoicing app also needs.

set_public_paths
Set public paths
Sets which of an app's paths are reachable WITHOUT login. By default an app is fully private (workspace login required everywhere). Pass the complete desired list of specific paths (e.g. ["/survey"]); each listed path and everything under it becomes public, everything else stays private. An empty list makes the app fully private again. The whole app cannot be made public — root or wildcard paths are rejected.

set_schedules
Set scheduled tasks
Sets the app's scheduled tasks. Each is { name, cron, path }: on the cron (standard 5-field, UTC) Croft makes an internal POST to the app's path, and the app does the work (e.g. send a daily email, sync an API). Use this for anything recurring instead of writing your own cron — it survives deploys and reboots and is shown in the panel. Also implement the endpoint (e.g. a POST route at that path). Pass the full desired list; an empty list clears all schedules.

status
App status
Reports an app's deploy and health status. `live` is true only when the latest deploy has fully succeeded; `deploy_state` gives the current stage (queued, running, succeeded, or failed). Read-only and safe to call repeatedly — each call returns the current stage, so it can be polled to follow a deploy's progress.

write_files
Write files
Writes files into an app's git repo and commits them (as 'Claude via Croft'). files is a list of {path, content}. Committed files are staged in the repo; they are not built or published until the app is deployed.
