Sequential Monitoring
Author’s activation text, quoted as published
Always-valid sequential inference for honest peeking at running A/B tests. Applies mSPRT (mixture Sequential Probability Ratio Test) or confidence sequences so the false-positive rate stays at the nominal alpha even when the test is checked daily. Use this skill when the user asks if it's safe to call an A/B test early, or to peek-check a running test. Pairs with experiment-result-reader and bayesian-experiment-reader, and with analytics-diagnostic-method for the framing discipline. Triggers when Clamp MCP returns mid-experiment exposure and conversion counts, or when a user references peeking, early stopping, sequential testing, alpha-spending, mSPRT, or confidence sequences. …

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, says when not to, 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 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.
