skill

Write, review, fix, optimize, and test code in any language or framework — HTML, CSS, JavaScript, React, Python and the rest — returned as complete copy-pasteable blocks. Also generates a B12 web app or website when someone wants the thing built rather than the source. Use when someone asks for code to be written, explained, reviewed, refactored, commented, or covered by unit tests, including asks like "create a website in HTML and CSS" or "write me a React counter". Do NOT use for work on the user's existing codebase or repository — editing project files, debugging a failing build, running a test suite — the host does that directly. …

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, 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.

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.
