mthines-agent-skills

mthines-agent-skills is a plugin for Claude Code from mthines/agent-skills. Its manifest loads nothing; the 48 skills, 5 agents it bundles cost 9,512 tokens per session together, scanned A, original, MIT.

A collection of agent skills and helpers for reviewing code, improving developer and user workflows, writing tests first, and analysing problems from several perspectives. TDD means test-driven development: writing a test before the code that makes it pass.

In plain words
What is it for?
Use it for code reviews, developer-experience and user-experience checks, test-driven development, broad problem analysis, and productivity work.
Why use it?
It provides reusable guidance for common development tasks instead of handling every review, test, or analysis process from scratch.

Security

Grade A, and why

mthines-agent-skills 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. 48 skills, 5 agents travel with it, and installing the plugin installs all of them — 9,512 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
