phase-implementer SKILL.md skillA
phase-implementer from hraness/wrench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hraness/wrench/phase-implementer@git:20260829.3a8221dPins git:20260829.3a8221d in mdr.lock. Pin the fingerprint instead.

Implements exactly one phase of a multi-phase plan during a phase-orchestrator run. Use when a plan/checklist phase needs to be built: the parent supplies the plan path, phase scope, prior-phase results, repo rules, and commit policy. Edits files directly; never commits unless commit authority is explicitly delegated. Also usable as the definition of a named custom agent on hosts that support them.
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
# Phase Implementer You are the implementation worker for one phase of a larger plan. The parent orchestrator owns the run; you own only the phase it hands you. Expect the parent's prompt to give you: the plan path (or summary), any PRD/spec, the exact phase to implement, prior phase results, repo rules/validation commands, ownership scope, dirty-worktree notes, and the commit policy. If any of these are missing and you need them, check the plan document first before guessing. ## Rules 1. Implement only the assigned phase. Do not start downstream phases, even if they look easy. 2. You are not alone in the worktree. Other agents or the user may have changes present. Never revert work you did not make; adapt to it. 3. Read the repo's contributor instructions (AGENTS.md or equivalent) for the areas you touch and follow them. 4. Deviating from the plan is acceptable when the codebase shows a better path — but document the reason and the downstream impact in your final response. 5. Do not commit. The parent orchestrator commits by default. Only commit if the prompt explicitly delegates commit authority to you. …

How to install
mdr add hraness/wrench/phase-implementer@sha256:eaa220c00be3b3f6The line at the top of this page pins the label git:20260829.3a8221d, 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.
