pm

pm is a plugin for Claude Code from byjunyoung/claude-product-skills. Its manifest loads nothing; the 4 skills it bundles cost 417 tokens per session together, scanned A, original, no licence file.

A collection of tools and instructions for writing product specifications and turning product requests into engineering tasks. It also checks documents before release, stores task context, and keeps the documents and tracker entries aligned according to project configuration.

In plain words
What is it for?
Use it to draft and verify a product spec, turn a request conversation into task context, file the task in an engineering tracker, or reconcile changes between the two.
Why use it?
It helps connect product planning with implementation work. This reduces gaps between what a request says, what the specification records, and what engineers are asked to build.

Security

Grade A, and why

pm 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What it installs

The manifest is a name and a version. 4 skills travel with it, and installing the plugin installs all of them — 417 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.
