HTTP/2 Client & Retry Recovery
Harden service clients across HTTP/2 GOAWAY, request-body replay, half-closed sockets, breaker races, timeout budgets, DNS changes, pool exhaustion, and retry storms. This bundle targets failures that appear during deploys, failovers, upstream restarts, slowdowns, and connection churn. Use it to make retries selective, bodies replay-safe, connection lifecycles bounded, and degraded dependency behavior recoverable.
Works with every agent that reads SKILL.md — Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Windsurf, OpenClaw, and more.

What's included
8 skills
Repair HTTP/2 GOAWAY drain bugs, stale pool reuse, unsafe stream retries, one-shot body replay, unknown outcomes, and replacement-connection herds.
Repair consumed request-body reuse, empty retry uploads, stream pre-consumption, unsafe replay, and unlimited buffering across HTTP retries and redirects.
Repair TCP half-close bugs that truncate responses, destroy both directions on EOF, omit FIN propagation, or leave writers hanging.
Repair circuit-breaker state races across closed, open, and half-open transitions without changing resilience policy.
Align end-to-end request deadlines, retries, cancellation, database work, and side-effect ownership so server work stops when its budget is gone.
Repair ignored DNS TTLs, startup-only resolution, stale endpoint reuse, retry-to-same-address loops, discovery refresh stampedes, and DNS/pool confusion.
Repair leaked or long-held connections, per-request client pools, fan-out saturation, retry amplification, and cleanup gaps without guessing pool sizes.
Repair retry loops that overload APIs, queues, and external services during outages.

Repair HTTP/2 GOAWAY Retry Bugs
Example session with this skill installed
Our Node/TypeScript API uses an HTTP/2 client pool to call an internal service. During rolling deploys the server sends GOAWAY. Our pool keeps the connection eligible for new requests until it actually closes, and the retry wrapper retries every failed request once on a fresh connection. We have concurrent GETs plus some POSTs with streaming bodies. Repair locally with an HTTP/2 test server that sends GOAWAY at controlled stream IDs. Do not call production, assume POSTs are idempotent, or buffer unlimited request bodies.

- Compiled the repair http 2
GOAWAY drain bug found. The pool keeps a draining session eligible for new streams and the retry wrapper ignores stream outcome, body replayability, and operation safety. The repair adds DRAINING state, stream-aware classification, bounded replacement creation, and deterministic GOAWAY tests. POST idempotency remains unverified.
