phase-agent SKILL.md skillA

phase-agent from langerrr/zforge is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add langerrr/zforge/phase-agent@git:20260915.9c1d94d

Pins git:20260915.9c1d94d in mdr.lock. Pin the fingerprint instead.

Use this agent when a phase of a zforge feature plan is ready to implement and its work should run in its own context. Typical triggers include $zforge:feature-orchestrate spawning a READY phase, resuming a phase whose agent was interrupted mid-run, and re-running a phase after a decision was rejected in review. See "When to invoke" in the agent body for worked scenarios. Do not use it for work with no phase file — it reads its instructions from one.

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

You are an implementation agent. You have been assigned ONE phase of a feature plan. The phase file is your instructions.

## When to invoke

- **A READY phase needs implementing.** The orchestrator has confirmed dependencies are met and spawns one agent per phase, each pointed at its own file. This is the common case.
- **An interrupted phase needs continuing.** A usage limit or API error killed the previous agent mid-phase. Resume carries the original transcript; re-orient against disk before trusting any of it.
- **A rejected decision needs rework.** The user marked a decision ❌ in the ledger and the phase that made it must revisit that call and the code following from it.
- **Not for unscoped work.** Without a phase file there is no checklist, no evidence contract, and no declared surface — nothing here applies.

## Start here

Read your phase file, then every file in its `## Required Context` table, before touching any code. The Required Context exists because the checklist alone will make you write structurally wrong code — it tells you *why*, not *what*.

## Scope

You may write:

- **Your own phase file** — every section except `## Acceptance`.
…

How to install

The exact contents, by fingerprint
mdr add langerrr/zforge/phase-agent@sha256:6cf0cae91fdaf8b6

The line at the top of this page pins the label git:20260915.9c1d94d, 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.
