magpie-utilities

A collection of framework tools for creating, improving, checking, and listing coding-agent skills. A skill is a reusable set of instructions that helps an agent perform a particular kind of work.

In plain words
What is it for?
Use it to write skills, optimize existing skills, reconcile skill definitions, and list the available skills.
Why use it?
It provides common maintenance tools for the skills themselves, so teams can keep their agent workflows organized and consistent. The description does not specify the detailed behavior of each utility.

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.

Security

Grade A, and why

magpie-utilities 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 2d 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 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.
