pi-delegate

npm · Pi package directory

Run focused coding tasks in separate Pi agents while the parent keeps working. Supports local and hosted models, background jobs, and one shared local worker across participating Pi sessions.

One child per call; no nested delegation.

Setup

Requires pi on PATH and configured model access. Choose one installation source:

pi install npm:@kvidzibo/pi-delegate
# Or a local checkout:
pi install /absolute/path/to/pi-delegate

Pi supplies the peer dependencies; no manual npm install is needed. Do not also add delegate to Pi's extensions setting. Published releases may lag behind this checkout.

Run /pi-delegate for the options menu. Esc from Models returns to this menu; Esc at the main menu closes it. Use /pi-delegate stats [session|today|all|rebuild] for a scrollable usage panel (Esc returns), or /pi-delegate models to choose each role's default model or reasoning level. Model choices match /model: scoped models when a scope is set, otherwise every available model. Select a role, then Model or Reasoning; changing reasoning leaves the model unchanged. Shipped model assignments are active defaults; unavailable models are not automatically replaced. Selections are saved in ~/.pi/agent/delegate.json and apply to new jobs in the current session.

Manual configuration edits, package updates and other open sessions need /reload or a restart. Reload stops outstanding children.

Use

Ask Pi:

Delegate a background recon to find this repo's test files and test commands.
Do not edit files. Collect the result when it finishes.

The parent can wait, peek, request wrap-up or cancel using the returned job ID. timeoutMs limits waiting, not runtime. Esc interrupting the parent also cancels its running and queued delegates, including background jobs. Active jobs appear above the editor; finished results appear in the transcript. Ctrl+O expands details.

Check receipts freeze elapsed runtime (or queue time) and the interval since the previous returned check; the first check omits the interval.

See configuration and job controls for manual settings and tool arguments.

Important constraints

• Shared local capacity requires Linux and /usr/bin/flock. All local providers share one slot per agent directory; hosted jobs bypass it. Reload older sessions to participate.
• No sandbox. Children have your system permissions; shipped roles include shell access. Read-only roles are prompt policy, not write protection. offline skips startup networking; it does not block tool network access.
• Children do not inherit the parent conversation or project instructions. Provide a self-contained task and avoid overlapping edits to shared files.
• Worker completion is not proof of task correctness. The parent must inspect and validate results.
• Archives under ~/.pi/agent/delegate/ are retained indefinitely and can contain sensitive prompts, code, thinking and tool output.

Development

Run from the repository root:

npm run test:unit       # no Pi required; also runs in CI
xvfb-run -a npm test    # includes offline CLI/UI checks; needs Pi and Xvfb

Tests make no model calls. Delegation guidance ships with the extension; do not duplicate role/model policy in AGENTS.md.

See child-runtime, opt-in benchmarks and the implementation contract when working on those areas.
