What is github-helper?

A local helper for finding, downloading, updating, and inspecting GitHub repositories. It also maintains a searchable local index of repositories and their locations.

Use it when you need to locate a repository, clone or sync it, inspect issues or pull requests, or update the local repository knowledge base.

It gives repository work a consistent starting point and checks local copies before searching GitHub again.

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.

agentmods

npx agentmods add skills/zrtch/awesome-skills/github-helper

Any agent

npx skills add zrtch/awesome-skills --skill github-helper

Clone the repo

git clone --depth 1 https://github.com/zrtch/awesome-skills

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5	$0.00060	$0.00697
Opus 5	$0.00030	$0.00349
Sonnet 5	$0.00012	$0.00139
Haiku 4.5	$0.00006	$0.00070

Security

Grade A, and why

github-helper 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 3d 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.

GitHub Helper

Overview

管理本地 GitHub 仓库目录，维护可检索知识库，并为仓库检索、克隆、Issue/PR 跟踪提供统一流程。

Local Repository Directory

Default path: /Users/liuchen/Documents/github

This path is referenced in the knowledge base file: @/Users/liuchen/Documents/github/CLAUDE.md

Core Workflows

1. Initialize or Update Knowledge Base

When first using this skill or when user requests an update:

Check if the github directory exists.
If not found, ask user for the correct path.
Scan the directory using scripts/scan_repos.py.
Update CLAUDE.md using scripts/update_kb.py.

Example:

# Scan repositories
python3 scripts/scan_repos.py /Users/liuchen/Documents/github

# Update knowledge base (pass repos as JSON)
python3 scripts/update_kb.py /Users/liuchen/Documents/github '[{"name":"repo1","path":"/path","summary":"desc"}]'

2. Search for Repository

When user mentions a repository name:

Check local first: Read @/Users/liuchen/Documents/github/CLAUDE.md.
If found locally: Use local path to analyze and answer.
If not found: Search GitHub using gh or GitHub MCP tools.
Offer to download: Ask user whether to clone.

3. Download Repository

When user requests to download/clone:

Clone to the github directory:

cd /Users/liuchen/Documents/github
git clone <repo-url>

After successful clone, update knowledge base:
- Run scripts/scan_repos.py to get repo info.
- Run scripts/update_kb.py to update CLAUDE.md.

4. GitHub Search Integration

Use gh CLI first, then fall back to GitHub MCP:

Search repositories

gh search repos <query> --limit 10

Search issues

gh issue list --repo <owner/repo> --state all --limit 20

Search PRs

gh pr list --repo <owner/repo> --state all --limit 20

Answering Repository Questions

Check whether repository exists in local knowledge base.
If local, prioritize local code inspection.
If information is insufficient, query GitHub issues/PRs/releases.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
