github-kb

A local index of GitHub repositories and technology topics. GitHub is a service where developers store and share code; the index can also gather project discoveries from web and social-media sources.

In plain words
What is it for?
Use it to search indexed repositories, sync the index with local Git folders, and discover GitHub projects related to a topic.
Why use it?
It helps you find repositories in a local collection and keep that collection up to date without searching through folders or websites manually.

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-kb 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/fetch_tweet.py, scripts/fetch_tweets.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Knowledge Base

Unified skill for local repo management + social media hot topic tracking.

Configuration

KB_PATH: Default ~/github. Customize in project CLAUDE.md:

KB_PATH: /your/path

Commands

/github-kb search <keyword>

Search local knowledge base.

  1. Read KB_PATH/CLAUDE.md index
  2. Match keyword against names, descriptions, tags
  3. Display matches with paths
  4. Offer to explore repo details

/github-kb update

Sync index with filesystem.

  1. Scan KB_PATH for .git directories
  2. Extract: name, README first line, tech stack tags
  3. Diff against existing CLAUDE.md
  4. Show changes, ask confirmation, write update

Index format (keep under 100 lines):

# GitHub Knowledge Base

| Name | Description | Path | Tags |
|------|-------------|------|------|
| repo | One-line desc | ./repo | tag1, tag2 |

/github-kb discover <topic>

Find trending repos from multiple sources.

  1. Gather (parallel):

  2. Extract GitHub URLs from results

  3. Enrich via gh repo view owner/repo --json name,description,stargazerCount

  4. Present candidates with source attribution

  5. Clone user-selected repos: gh repo clone owner/repo

  6. Update index automatically

/github-kb xiaohongshu <keyword>

Direct Xiaohongshu search. See references/xiaohongshu.md.

/github-kb twitter <url>

Fetch Twitter/X content. See references/twitter.md.

Files

What ships with it

5 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.
