skill-create

A command that examines a repository's Git history and creates a SKILL.md file describing recurring coding patterns and team practices.

In plain words
What is it for?
Use it to study recent commits, detect commit and file-change conventions, document repeated workflows, and optionally create instincts for a continuous-learning system.
Why use it?
It turns patterns spread across commits and file changes into written guidance that an AI coding agent can follow.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 32 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

skill-create 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 yesterday.

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.

/skill-create - 本地技能生成(Local Skill Generation)

分析你仓库的 Git 历史记录以提取编码模式,并生成 SKILL.md 文件,以便让 Claude 学习你团队的工程实践。

用法(Usage)

/skill-create                    # 分析当前仓库
/skill-create --commits 100      # 分析最近 100 条提交
/skill-create --output ./skills  # 指定自定义输出目录
/skill-create --instincts        # 同时为 continuous-learning-v2 生成直觉(instincts)

功能说明(What It Does)

  1. 解析 Git 历史 - 分析提交(commits)、文件变更和模式。
  2. 检测模式 - 识别循环出现的工作流(Workflow)和约定。
  3. 生成 SKILL.md - 创建有效的 Claude Code 技能(Skill)文件。
  4. 可选生成直觉(Instincts) - 用于 continuous-learning-v2 系统。

分析步骤(Analysis Steps)

第 1 步:收集 Git 数据

# 获取带有文件变更的近期提交
git log --oneline -n ${COMMITS:-200} --name-only --pretty=format:"%H|%s|%ad" --date=short

# 获取按文件统计的提交频率
git log --oneline -n 200 --name-only | grep -v "^$" | grep -v "^[a-f0-9]" | sort | uniq -c | sort -rn | head -20

# 获取提交信息模式
git log --oneline -n 200 | cut -d' ' -f2- | head -50

第 2 步:检测模式

寻找以下模式类型:

模式 (Pattern) 检测方法 (Detection Method)
提交规范 (Commit conventions) 对提交信息使用正则匹配 (feat:, fix:, chore:)
文件关联变更 (File co-changes) 总是同时发生变化的文件
工作流序列 (Workflow sequences) 重复出现的文件变更模式
架构 (Architecture) 文件夹结构和命名规范
测试模式 (Testing patterns) 测试文件位置、命名、覆盖率

第 3 步:生成 SKILL.md

输出格式:

---
name: {repo-name}-patterns
description: Coding patterns extracted from {repo-name}
version: 1.0.0
source: local-git-analysis
analyzed_commits: {count}
---

# {Repo Name} 模式

## 提交规范
{检测到的提交信息模式}

## 代码架构
{检测到的文件夹结构和组织方式}

## 工作流
{检测到的重复文件变更模式}

## 测试模式
{检测到的测试约定}

第 4 步:生成直觉 (如果使用了 --instincts)

用于 continuous-learning-v2 集成:

---
id: {repo}-commit-convention
trigger: "when writing a commit message"
confidence: 0.8
domain: git
source: local-repo-analysis
---

# 使用约定式提交 (Conventional Commits)

## 操作 (Action)
在提交信息前添加前缀:feat:, fix:, chore:, docs:, test:, refactor:

## 证据 (Evidence)
- 已分析 {n} 条提交
- {percentage}% 遵循约定式提交格式

输出示例

在 TypeScript 项目上运行 /skill-create 可能会产生:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

skill-create is a command published in the GitHub repository codelably/harmony-claude-code (42 stars, last pushed 6mo ago), licensed MIT. It adds 32 tokens to every session and 1,372 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
