Sizes database connection pools for Postgres/MySQL apps from a short JSON of services, pods, workers, threads and pool settings - worst-case connections at autoscale max and during deploy surges vs max_connections, busy connections from rps x hold time, per-process wait odds (Erlang C), CPU and memory limits, PgBouncer client and server limits. Recommends pool sizes or proxy settings. Includes an offline stdlib Python calculator with --self-test. 来源：https://prompts.chat/prompts/cmvxi8kpe0008l508b4ttzkaq
Checks pip requirements and constraints files offline before they break a build - unpinned and lower-bound-only packages, PEP 440 specifier conflicts across files and markers, git refs without a commit hash, editable and local paths, partial hash mode, pre-releases, --extra-index-url dependency confusion, http indexes, stdlib backports, dev tools in runtime files and pip freeze drift. Includes a stdlib Python checker with --self-test. 来源：https://prompts.chat/prompts/cmvyxzied0001k108wkm9h02b
