pi-aim0.0.2

pi-aim

Codex-style goals for pi, where completion is checked by an evaluator model instead of trusted from the worker.

Install

pi install npm:pi-aim

How it works

• /goal <objective> resolves the evaluator model, saves the goal in the session and starts working.
• While the goal is active, every finished run is followed by a continuation prompt, so the agent keeps going across turns.
• The agent calls the update_goal tool:
  • complete: the evaluator judges the objective against the tool calls and outputs recorded since the goal started (not the agent's own summary). verified completes the goal; incomplete or inconclusive is returned to the agent as an error and work continues. If the evaluation itself fails, the goal is blocked; it is never marked complete without a verdict.
  • blocked: the agent is stuck on the same blocker for three turns.
• After compaction, an active goal's objective is restated before the next model call, so it cannot be summarized away.
• Escape pauses the goal. Three consecutive runs without any tool work also pause it.
• The footer shows the status and the start of the objective (goal: active · Migrate the billing service…). Press alt+g to show or hide the full goal above the editor (on macOS the terminal must send Option as Meta).

Commands

• /goal <objective> starts (or replaces) a goal.
• /goal status shows the goal and re-checks that the saved evaluator is still available (it is never re-selected).
• /goal resume resumes a paused or blocked goal.
• /goal clear removes the goal.

Goal: Implement authentication
Status: Active
Worker: openai/gpt-6-luna
Evaluator: openai/gpt-6-luna
Evaluator selection: worker
Evaluator reason: same model as worker
Verification: hybrid

Configuration

Optional ~/.pi/agent/pi-aim.json (or under PI_CODING_AGENT_DIR). Defaults:

{
  "verification": {
    "mode": "hybrid",
    "model": "worker",
    "thinkingLevel": "low",
    "timeoutMs": 60000,
    "maxAttempts": 2,
    "failClosed": true
  }
}

• model: "worker" (the model active when the goal starts) or an explicit "provider/modelId". Either must be authenticated, accept text and have a 32k+ context window; otherwise the goal is blocked. The choice is saved and never changes for that goal.
• mode: "deterministic" never selects or calls an LLM. Deterministic checks are not implemented yet, so such goals start blocked rather than trusting the agent. hybrid and llm currently behave the same.
• Invalid settings block the goal instead of falling back to defaults.

Checking the evaluator prompt against real models

PI_AIM_LIVE=1 PI_AIM_MODELS=provider/model-id,... bun run test:live

Development

bun install
bun fmt --check && bun run lint && bun run typecheck && bun run test

Release

Publishing runs from .github/workflows/publish.yml with npm trusted publishing (OIDC, no token, automatic provenance).

First release (0.0.1):

1. Run the checks above and npm pack --dry-run. In a local checkout, temporarily set version in package.json to 0.0.1-stage.0 and run npm publish --tag stage from an authenticated terminal. Restore 0.0.1 without committing the change.
2. On npmjs.com, configure a GitHub Actions trusted publisher with owner mkusaka, repository pi-aim and workflow filename publish.yml. Allow direct npm publish.
3. Push tag v0.0.1 for the release commit within two days of step 2.

The placeholder lets npm create the package before trusted publishing can be configured; it stays on the stage dist-tag, so latest starts at 0.0.1.

Later releases: bump version, run bun install and the checks, commit, and push the matching vX.Y.Z tag. The workflow reruns the checks, verifies that the tag matches package.json, and skips versions already on npm.
