fork-and-pr

fork-and-pr is a plugin for Claude Code from j-256/agent-skills. Its manifest loads nothing; the 1 skill it bundles cost 61 tokens per session together, scanned A, original, MIT.

A guide for contributing to someone else’s GitHub repository, a shared code project, by making a fork and one pull request. A fork is your own copy, and a pull request asks the original project to review your changes.

In plain words
What is it for?
Use it to prepare a branch, commit changes, push them to your fork, and open one pull request against the upstream repository.
Why use it?
It removes the uncertainty around contributing when you cannot write directly to the original repository. It covers the usual steps from copying the project through requesting review.

Security

Grade A, and why

fork-and-pr 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.

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 61 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.
