han-github

han-github is a plugin for Claude Code from testdouble/han. Its manifest loads nothing; the 3 skills it bundles cost 280 tokens per session together, scanned A, original, MIT.

A GitHub-focused extension for the Han plugin, adding skills for planning and coding work around GitHub. GitHub is a service for hosting code and managing changes through pull requests.

In plain words
What is it for?
Use it to post code reviews as pull-request comments and update pull-request descriptions with a consistent format.
Why use it?
It provides a consistent way to handle common GitHub collaboration tasks instead of setting up those workflows separately.

Security

Grade A, and why

han-github 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.

What it installs

The manifest is a name and a version. 3 skills travel with it, and installing the plugin installs all of them — 280 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
