Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

git-precommit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to git-precommit — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Git 提交前工作流(編排器)

描述

協調多個 Skills 完成 Git 提交前的所有準備工作。這是一個「編排器」Skill,負責調用其他 Skills。

  • 「準備 commit」「GIT」「gc」
  • 「要提交了」「git commit」
  • 「推送」「push」

法規依據

  • 憲法:CONSTITUTION.md 第三章
  • 子法:.github/bylaws/git-workflow.md

🔧 操作步驟(編排流程)

Step 1: 收集變更資訊

git status --short
git diff --name-only --cached

使用工具:

get_changed_files()  # 取得變更清單

Step 2: 執行 memory-updater(必要)

呼叫條件:永遠執行

調用 memory-updater skill:
- 更新 activeContext.md(當前焦點)
- 更新 progress.md(移動 Done/Doing)

Step 3: 執行 readme-updater(條件)

呼叫條件

  • 新增功能(src/ 有新檔案)
  • 依賴變更(pyproject.toml/package.json 變更)
