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.

Use it to post code reviews as pull-request comments and update pull-request descriptions with a consistent format.

It provides a consistent way to handle common GitHub collaboration tasks instead of setting up those workflows separately.

han-github — Plugin for Claude Code by testdouble/han

Install

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.

Clone the repo

git clone --depth 1 https://github.com/testdouble/han

Made for: Claude Code.

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 1mo 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.

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.

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.
