profiling-slow-api-endpoints

profiling-slow-api-endpoints is a Backend performance & caching skill for AI agents, published by PostHog in the posthog repository on GitHub. Skillspace rates profiling-slow-api-endpoints D (58/100) and it passed the safety scan; the rating is based on static analysis only.

Profiles slow PostHog API endpoints when the main cost is in Postgres or Python. Use when a screen, picker, or list is slow; a Django endpoint has high tail latency; a query plan changes with tenant size; or a proposed database fix needs production evidence. Covers APM traces, safe production EXPLAIN, representative measurements, implementation choices, tests, rollout, and post-deploy verification. For ClickHouse or HogQL latency, use `optimizing-clickhouse-and-hogql-queries` instead.
