Skill Stocktake is an agent skill from affaan-m/ECC. Claudeのスキルとコマンドの品質を監査するためのツール。変更されたスキルのみを対象とした高速スキャンと、順次サブエージェントバッチ評価を使用した完全棚卸しモードをサポートする。
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Skill management. It works with Bash. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4eb71d9. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
bashFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Skill Stocktake loads about 1.4k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 254 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/skill-stocktake/SKILL.md (or your agent's skills folder).品質チェックリスト + AI全体判断を使用して、すべてのClaudeスキルとコマンドを審査するスラッシュコマンド(/skill-stocktake)。2つのモードをサポートする:最近変更されたスキルの高速スキャンと、完全レビューのための完全棚卸し。
このコマンドは、コマンドを呼び出したディレクトリを基準とした以下のパスを対象とする:
| パス | 説明 |
|---|---|
~/.claude/skills/ | グローバルスキル(全プロジェクト) |
{cwd}/.claude/skills/ | プロジェクトレベルのスキル(ディレクトリが存在する場合) |
フェーズ1の開始時に、コマンドはどのパスが見つかりスキャンされたかを明示的にリストアップする。
プロジェクトレベルのスキルを含めるには、そのプロジェクトのルートから実行する:
cd ~/path/to/my-project
/skill-stocktakeプロジェクトに .claude/skills/ ディレクトリがない場合、グローバルスキルとコマンドのみが評価される。
| モード | トリガー条件 | 所要時間 |
|---|---|---|
| 高速スキャン | results.json が存在する(デフォルト) | 5〜10分 |
| 完全棚卸し | results.json が存在しない、または /skill-stocktake full | 20〜30分 |
結果キャッシュ: ~/.claude/skills/skill-stocktake/results.json
前回の実行以降に変更されたスキルのみを再評価する(5〜10分)。
~/.claude/skills/skill-stocktake/results.json を読み取るbash ~/.claude/skills/skill-stocktake/scripts/quick-diff.sh \ ~/.claude/skills/skill-stocktake/results.json
(プロジェクトディレクトリは $PWD/.claude/skills から自動検出。必要な場合のみ明示的に渡す)[] の場合:「前回の実行以降に変更なし。」とレポートして停止するbash ~/.claude/skills/skill-stocktake/scripts/save-results.sh \ ~/.claude/skills/skill-stocktake/results.json <<< "$EVAL_RESULTS"実行する:bash ~/.claude/skills/skill-stocktake/scripts/scan.sh
スクリプトはスキルファイルを列挙し、フロントマターを抽出し、UTC修正時刻を収集する。
プロジェクトディレクトリは $PWD/.claude/skills から自動検出。必要な場合のみ明示的に渡す。
スクリプト出力からスキャンサマリーとインベントリテーブルを表示する:
スキャン中:
✓ ~/.claude/skills/ (17 個のファイル)
✗ {cwd}/.claude/skills/ (見つからない — グローバルスキルのみ)| スキル | 7日間使用 | 30日間使用 | 説明 |

完全なインベントリとチェック項目を含む汎用エージェントツールのサブエージェントを起動する:

チェックリストに基づいて以下のスキルインベントリを評価してください。
[INVENTORY]
[CHECKLIST]
各スキルについてJSONを返してください:
{ \"verdict\": \"Keep\"|\"Improve\"|\"Update\"|\"Retire\"|\"Merge into [X]\", \"reason\": \"...\" }
"
)サブエージェントは各スキルを読み取り、チェック項目を適用し、各スキルのJSON結果を返す:
{ "verdict": "Keep"|"Improve"|"Update"|"Retire"|"Merge into [X]", "reason": "..." }
チャンク指針: 各サブエージェント呼び出しは約20個のスキルを処理し、コンテキストを管理可能に保つ。各チャンクの後、中間結果を results.json に保存する(status: "in_progress")。
全スキルの評価が完了したら:status: "completed" を設定し、フェーズ3に進む。
再開検出: 起動時に status: "in_progress" が見つかった場合、最初の未評価スキルから再開する。
各スキルはこのチェックリストに基づいて評価される:
- [ ] 他のスキルとの内容の重複を確認済み
- [ ] MEMORY.md / CLAUDE.md との重複を確認済み
- [ ] 技術的参照の時効性を確認済み(ツール名 / CLI引数 / APIが存在する場合、WebSearchで検証)
- [ ] 使用頻度を考慮済み判定基準:
| 判定 | 意味 |
|---|---|
| Keep | 有用かつ最新 |
| Improve | 保持する価値があるが、特定の改善が必要 |
| Update | 参照された技術が古い(WebSearchで検証) |
| Retire | 品質が低い、陳腐化、またはコストが非対称 |
| Merge into [X] | 別のスキルと大幅に重複している。マージターゲットを命名する |

Claudeのスキルとコマンドの品質を監査するためのツール。変更されたスキルのみを対象とした高速スキャンと、順次サブエージェントバッチ評価を使用した完全棚卸しモードをサポートする。. Skill Stocktake is an agent skill from affaan-m/ECC.
Skill Stocktake fits situations like: tasks that involve Skill management.
Run `npx skills add affaan-m/ECC --skill skill-stocktake -a claude-code`. Or copy the skill folder (docs/ja-JP/skills/skill-stocktake in affaan-m/ECC) into .claude/skills/skill-stocktake in your project. Claude Code loads it when a task matches its description.
Run `npx skills add affaan-m/ECC --skill skill-stocktake -a codex`. Or copy the skill folder (docs/ja-JP/skills/skill-stocktake in affaan-m/ECC) into .agents/skills/skill-stocktake in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add affaan-m/ECC --skill skill-stocktake -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/skill-stocktake, .gemini/skills/skill-stocktake, .github/skills/skill-stocktake and .opencode/skills/skill-stocktake in your project.
Going by SKILL.md and its folder, Skill Stocktake needs the command-line tools its instructions call (bash). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Skill Stocktake is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Skill Stocktake: Code Improver (trailofbits/skills, 7.5k stars), Skill Improver (trailofbits/skills, 7.5k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars) and Plugin Settings Pattern (anthropics/claude-plugins-official, 38k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
affaan-m (a GitHub user) maintains it in affaan-m/ECC, which has 276,111 GitHub stars. The repository holds 683 skills in this directory. The repository was last updated on October 10, 2026.
