Janus
Check a contract hook at the threshold it controls: what it may observe and change before a host action, what it may change after, and what it must never touch. Use when someone has a host protocol that calls hooks and wants to state and enforce the permitted effects, when reviewing a new hook against a host's economic contract rather than only its ABI, or when a hook must be shown safe on its exit and revert paths, not only its entry. Do not use it to fuzz one repository for generic Solidity defects; that is fizz. Never report a hook as conformant on a delta the recorder did not fully capture.

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, covers setup and states a limitation.
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 doctorReads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.
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.
