implementation-chain SKILL.md skillA
implementation-chain from shimo4228/claude-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add shimo4228/claude-harness/implementation-chain@git:20261008.b63e5f1Pins git:20261008.b63e5f1 in mdr.lock. Pin the fingerprint instead.

Decide the task type (feat / fix / refactor / chore / prototype / writing) and front-load its review chain and gates into the plan. Use when starting to implement, fix, refactor or write something (これから実装する), or when deciding which reviews to run.
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
# Implementation Chain 実装に着手する前にタスク種別を判定し、対応する chain を **plan に front-load** する。 実装中は判定をやり直さず、定義済みの chain をそのまま実行する。 commit / push / 公開の権限は task request と substrate が持つ。この skill は追加の人間 gate を作らない。 ## タスク種別判定（最初の plan ステップ） | 種別 | 判定基準 | 例 | |------|---------|-----| | `feat` | 新規機能・新規モジュール追加 | API 追加, 新ページ | | `fix` | バグ修正（再現可能な不具合） | crash, 誤動作 | | `refactor` | 振る舞いを変えない構造変更 | 抽出, 改名, 整理 | | `chore` | 設定 / 依存更新 / コード付随の docs 追従 | settings, CI | | `prototype` | 学習・スパイク・本番外コード | 検証スクリプト | | `writing` | 文書自体が一次成果物 | README 改稿, 記事, 論文, llms.txt | `prototype` を選ぶ場合は **「prototype として扱う理由」を plan に必須記載**（fix/feat の悪用防止）。 **harness 自体の変更**: 対象が `~/.claude` の rules / skills / hooks / agents / settings なら、種別に関わらず Plan で skill: `harness-boundary` を 1 回通す（どの層に置くか・モデルに任せられないか・runtime 交換後も残すか。1 行の判断で足りる）。 **README の種別判定**: README 自体の改善・書き直しが目的なら `writing`（Writing Chain → readme-writer）。コード変更に付随する README 追従更新はコードチェーンの Doc Sync で、readme-writer の Incremental モードを使う。 **大きい feat の Plan の補助**: 探索が互いに独立した複数の領域にまたがるときは Explore agent を並列で使い、 各 agent に「主ループが読むべきファイル 5〜10」を返させて読む。設計代替は主ループが並べて比較し、推奨を 添えてユーザーに選ばせる（収束の所在は Matrix の Plan 行）。 **実行者の決定**（Plan の最後、必須）: plan が固まったら …

How to install
mdr add shimo4228/claude-harness/implementation-chain@sha256:a149a69c0a6ca105The line at the top of this page pins the label git:20261008.b63e5f1, 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.
