To extend scope mid-work, file an additional +`in_progress` task (its globs union into the active scope) or re-issue +`dkg_add_task` for the same `taskUri` with the extended `scopedToPath`. + +When the work is done: + +```ts +dkg_update_task_status({ + taskUri: 'urn:dkg:task:peer-sync-auth', + status: 'done', +}) +``` + +The next scope read drops its globs automatically. + +### Hardcoded protected paths + +Always denied unless bootstrap mode is active: + +``` +.cursor/hooks/** .cursor/hooks.json .cursor/rules/agent-scope.mdc +.claude/hooks/** .claude/settings.json +agent-scope/lib/** agent-scope/.bootstrap-token +AGENTS.md GEMINI.md .cursorrules +``` + +Bootstrap mode is enabled by either `AGENT_SCOPE_BOOTSTRAP=1` in the +environment or `agent-scope/.bootstrap-token` existing on disk. **Both +must be set by the human, not by you.** If you need to modify a +protected file, STOP and ask the user to: + +``` +touch agent-scope/.bootstrap-token +``` + +…then remind them to `rm agent-scope/.bootstrap-token` when the +protected work is done. + +### Plan-mode denial protocol — MANDATORY when a write is blocked + +The denial message starts with an `agent-scope:` summary line and +contains a fenced JSON block: + +``` + +{ humanSummary, simpleOptions, recommendedOptionId, options, ... } + +``` + +When you see this, STOP.

The flow is: + +1. **Plan first.** When the user starts a new piece of work, propose the scope as a single short question ("I'd like to refactor X — scope to `packages/agent/**`, `packages/core/**`, inherit the standard build-artefact exemptions. Sound good?"). Use `AskQuestion` with two options: `go` (recommended) and `custom_instruction` (free text). Don't write any files yet. +2. **On `go`, file the task in the DKG.** Call `dkg_add_task` with: + - `title` — imperative summary of the work + - `status: "in_progress"` — this flips the scope live immediately + - `scopedToPath: ["packages/agent/**", "packages/core/**", "!**/secrets.*"]` — the operational allow-list + - `touches: []` — for human readability / cross-referencing (NOT what the guard evaluates; that's `scopedToPath`) +3. **Label your turns.** On every substantive turn while the task is in progress, include `worksOn: ` in `dkg_annotate_turn` (or emit `chat:worksOn` directly). This is pure observability — it's how a teammate later runs "what did Claude discuss while working on the peer-sync refactor" as a single SPARQL. +4. **Flip status when you ship.** Call `dkg_update_task_status({ taskUri, status: "done" })`. The scope is retracted automatically — the guard now blocks writes to those globs again until a new task goes `in_progress`. + +The guard's SPARQL, for reference: it queries for every `tasks:Task` where the most recent `tasks:status` (by `dcterms:modified`) is `"in_progress"` AND `prov:wasAttributedTo = `, then takes the **union** of their `tasks:scopedToPath` literals as the live allow-list. So: + +- One in-progress task → that task's globs are your scope. +- Multiple in-progress tasks (e.g. you spun up two parallel work items) → union of all their globs. Both scopes apply simultaneously. +- Zero in-progress tasks → nothing the agent writes is in scope (default-deny).
