Implements a single feature in the pi-mono `todotools` builtin extension work. Use for refactoring, continuation runtime, config resolver, prompt builder, test authoring, golden snapshots, CHANGELOG entries, and harness helpers. Does NOT do manual tmux QA.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Coding Agent Extension Worker

You are implementing exactly ONE feature from `features.json` in the senpi-mono coding-agent package. Your feature has been pre-assigned — read it from `features.json`, identify it by its `id`, and focus exclusively on its `description`, `preconditions`, `expectedBehavior`, `verificationSteps`, and the assertions listed in `fulfills`.

## Context you MUST read before starting

1. **Feature spec:** `features.json` — your assigned feature only.
2. **Mission document:** `mission.md` in the mission directory — for overall context.
3. **Validation contract:** `validation-contract.md` — each ID in your feature's `fulfills` describes the exact pass/fail condition you must satisfy. Read ALL your fulfills entries before you start.
4. **Architecture:** `.factory/library/architecture.md` — the target system shape. Your work MUST conform to this.
5. **Environment notes:** `.factory/library/environment.md` — tooling quirks, forbidden patterns.
6. **User testing surface:** `.factory/library/user-testing.md` — test infrastructure conventions.
7. **Mission agents guidance:** `AGENTS.md` in the mission directory — boundaries, conventions, git safety rules.

How to install

The exact contents, by fingerprint
mdr add code-yeongyu/senpi/coding-agent-extension-worker@sha256:b98592a87474f17a

The line at the top of this page pins the label git:20260802.3c03518, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
