github-explorer

A method for investigating GitHub projects by examining their code repository, issues, commits, community activity, and related sources.

In plain words
What is it for?
Use it to identify a repository, collect project details, review reported problems and changes, assess community health, and compare the project with alternatives.
Why use it?
It helps you judge how a project is built, maintained, and used instead of relying only on its README, which is its introductory project page.

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.

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

github-explorer scanned grade A with 1 finding 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

GitHub Explorer — 项目深度分析

Philosophy: README 只是门面,真正的价值藏在 Issues、Commits 和社区讨论里。

Workflow

[项目名] → [1. 定位 Repo] → [2. 多源采集] → [3. 分析研判] → [4. 结构化输出]

Phase 1: 定位 Repo

  • web_search 搜索 site:github.com <project_name> 确认完整 org/repo
  • search-layer(Deep 模式 + 意图感知)补充获取社区链接和非 GitHub 资源:
    python3 skills/search-layer/scripts/search.py \
      --queries "<project_name> review" "<project_name> 评测 使用体验" \
      --mode deep --intent exploratory --num 5
    
  • web_fetch 抓取 repo 主页获取基础信息(README、Stars、Forks、License、最近更新)

Phase 2: 多源采集(并行)

⚠️ GitHub 页面抓取规则(强制):GitHub repo 页面是 SPA(客户端渲染),web_fetch 只能拿到导航栏壳子,禁止用 web_fetch 抓 github.com 的 repo 页面。一律使用 GitHub API:

  • README: curl -s -H "Authorization: token {PAT}" -H "Accept: application/vnd.github.v3.raw" "https://api.github.com/repos/{owner}/{repo}/readme"
  • Repo 元数据: curl -s -H "Authorization: token {PAT}" "https://api.github.com/repos/{owner}/{repo}"
  • Issues: curl -s -H "Authorization: token {PAT}" "https://api.github.com/repos/{owner}/{repo}/issues?state=all&sort=comments&per_page=10"
  • Commits: curl -s -H "Authorization: token {PAT}" "https://api.github.com/repos/{owner}/{repo}/commits?per_page=10"
  • File tree: curl -s -H "Authorization: token {PAT}" "https://api.github.com/repos/{owner}/{repo}/git/trees/{branch}?recursive=1"

PAT 见 TOOLS.md。

以下来源按需检查,有则采集,无则跳过:

来源 URL 模式 采集内容 建议工具
GitHub Repo github.com/{org}/{repo} README、About、Contributors web_fetch
GitHub Issues github.com/{org}/{repo}/issues?q=sort:comments Top 3-5 高质量 Issue browser
中文社区 微信/知乎/小红书 深度评测、使用经验 content-extract

search-layer 调用规范

search-layer v2 支持意图感知评分。github-explorer 场景下的推荐用法:

场景 命令 说明
项目调研(默认) python3 skills/search-layer/scripts/search.py --queries "<project> review" "<project> 评测" --mode deep --intent exploratory --num 5 多查询并行,按权威性排序
最新动态 python3 skills/search-layer/scripts/search.py "<project> latest release" --mode deep --intent status --freshness pw --num 5 优先新鲜度,过滤一周内
竞品对比 python3 skills/search-layer/scripts/search.py --queries "<project> vs <competitor>" "<project> alternatives" --mode deep --intent comparison --num 5 对比意图,关键词+权威双权重
快速查链接 python3 skills/search-layer/scripts/search.py "<project> official docs" --mode fast --intent resource --num 3 精确匹配,最快

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.
