Ln 652 Transaction Correctness Auditor

levnikolaevich/claude-code-skills
370 installs533 stars
Summary

This is a specialized auditor that hunts down database transaction bugs before they bite you in production. It checks for the stuff that code review misses: missing commits that break real-time notifications when pg_notify events get deferred, transactions held open during HTTP calls that starve your connection pool, and rollback handling that assumes the happy path. The two-layer detection approach (candidate scan then context verification) is smart, especially for tracing whether updates to trigger-affected tables actually have intermediate commits for progress tracking. It calculates a compliance score and writes structured findings with severity ratings. Best used when you're running Postgres with triggers and asyncio, or when you've had "why didn't the webhook fire" incidents that turned out to be transaction scope issues.

paper-planning

evoscientist/evoskills

Guides pre-writing planning for academic papers with 4 structured steps: story design (task-challenge-insight-contribution-advantage), experiment planning (comparisons + ablations), figure design (pipeline + teaser), and 4-week timeline management. Includes counterintuitive planning tactics (write a mock rejection letter to identify weaknesses before writing, narrow before broad claims, design ablations first). Use when: user wants to plan a paper before writing, design story/contributions, plan experiments, create figure sketches, set a writing timeline, or write a pre-emptive rejection letter for planning purposes. Do NOT use for actual writing (use paper-writing), running experiments (use experiment-pipeline), self-reviewing a finished draft (use paper-review), or finding research problems (use research-ideation).
