Cursor's **rules** engine reliably injects `alwaysApply` rules, so +`recall.ts` writes the recalled notes into `/.cursor/rules/atlaso-recall.mdc`. +Rewritten each session; safe to `.gitignore`. + +### Capture is automatic + scrubbed +`stop` / `sessionEnd` pull the exchange from the documented payload fields +(`afterAgentResponse.text` / `beforeSubmitPrompt.prompt`) or, as a fallback, the +`transcript_path` file (parsed defensively — its on-disk format is undocumented). +A commodity worth-keeping gate skips chatter; **secrets are scrubbed client-side** +before anything leaves the machine (the server re-scrubs too). Scope (personal vs +project) + a project key are inferred and tagged, preserving the dual-memory model. + +### First-run authorize +On the first session with no `~/.atlaso/auth.json`, `recall.ts` kicks a detached +browser-authorize flow (`hooks/connect.ts`, an RFC-8628 device flow) that writes +the **shared** auth.json every connector uses. One device token → the whole plugin +is one device (fits the free 1-device cap). + +### Cloud agents +Cursor cloud / background agents don't run `sessionStart` / `stop` / `sessionEnd`, +so there's no automatic loop there — interactive desktop Cursor gets the full loop. + +## v1 scope (online-first) +**Per-tool credentials landed** — the plugin mints and holds its OWN token at +`~/.atlaso/tools/cursor.json` (a kernel-locked exchange from the shared bearer; +`lib/credential.ts` + `lib/lock.ts`), so "remove Cursor" revokes only Cursor and a +verified server verdict is the ONLY thing that can take it offline (never-brick). +Still deferred (flagged, not hidden) vs the Python thin client: the **offline cache ++ outbox/sync**. v1 talks to the brain directly; with no token it simply no-ops +(memory never breaks a turn).
