Runtime Validation

skill

Catch the bugs a green test suite misses by observing REAL runtime behavior — tail application logs during test/server runs, validate API responses against their schema contracts, and assert data-integrity invariants (density ≤ 1.0, %≤100, referential integrity). Use when unit tests pass 100% but the running app still errors, when a Pydantic/Zod/serde validation error or schema drift shows up only at runtime, when reviewing whether a test suite actually exercises the running system, or when someone says "all tests pass but it's broken", "smoke test", "the mocks lied", or "verify it works live".

cp -r runtime-validation ~/.claude/skills/

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

Its own instructions

Its SKILL.md says when to use it, shows worked examples and covers setup.

Read from the capability’s own SKILL.md. This is not a grade and does not compare to the instruction-depth verdict on an MCP server — a skill has no tools to document, so that rubric does not apply to it.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

tashan Pro$6/mo

Pro adds the history to tashan doctor, so a run over your own config says which of yours gained an advisory, started running an install script, or lost its last maintainer — and what to move to.

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
