A plugin that tells a codebase's story in product language, with a short overview, an importance-weighted file tree, file summaries, and release-note-style explanations of code changes.

It is used to explore a repository, explain important files, understand pull requests and diffs, and learn basic engineering concepts.

It helps product-minded readers understand how software is organised and what changed without reading every line of code.

Security

Grade C, and why

decode scanned grade C with 1 finding 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

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.
