Production Runtime Survival Suite
Strengthen production runtimes across async context, event-loop pressure, descriptor ownership, consumer rebalances, HTTP/2 retries, buffered output, child processes, and worker starvation. This bundle concentrates the newest repository-repair skills into one broad operational survival suite. Use it when failures cross networking, scheduling, I/O, messaging, and process boundaries and need coordinated fixes instead of isolated patches.
Works with every agent that reads SKILL.md — Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Windsurf, OpenClaw, and more.
One payment, lifetime access. 8 skills unlock instantly in your library.
What's included
8 skills
Repair lost or stale async context, cross-request/tenant contamination, ThreadLocal leaks, detached task inheritance, and over-broad context propagation.
Repair event-loop starvation from synchronous CPU work, blocking libraries, long callbacks, microtask monopolization, and unsafe offload boundaries.
Repair file descriptor and handle leaks from files, streams, watchers, pipes, subprocesses, early returns, retries, errors, and cancellations.
Repair stale consumer ownership, rebalance races, old-generation commits, lease-loss overlap, late callbacks, and ack/commit authority bugs.
Repair HTTP/2 GOAWAY drain bugs, stale pool reuse, unsafe stream retries, one-shot body replay, unknown outcomes, and replacement-connection herds.
Repair missing flushes, ignored finalization errors, close-order inversions, premature success, and buffered output lost before it reaches the intended sink.
Repair zombie children, kill-without-wait paths, double wait races, orphaned descendants, blocked subprocess pipes, and shutdown hangs.
Repair thread-pool starvation from nested waits, callback affinity, fan-out, or shutdown competition without adding capacity.

Repair Async Context Leakage
Example session with this skill installed
Our Node/TypeScript SaaS uses AsyncLocalStorage for requestId, tenantId, userId, and traceId. A webhook handler schedules work with setImmediate, one helper caches the current context object in module scope, and a background email task is started with void sendEmail(). Under concurrency we occasionally see a log line with the correct requestId but the wrong tenantId. One detached task also keeps userId after the HTTP response is finished. Repair the repository with synthetic tenants and deterministic concurrency tests. Do not access production logs/data, change auth policy, or copy tokens into context.
- Read your context and instructions
- Compiled the repair async context
Async context leakage found. A module-level cached context can outlive its request, detached work inherits request identity, and logging can combine mismatched ownership paths. The repair removes global context reuse, makes durable metadata explicit, restores/clears context at owned boundaries, and adds deterministic cross-tenant concurrency tests. Production isolation remains unverified.
How to use
Skills on Agensi run inside your AI agent. Copy the prompt, paste it into your agent, and it connects to Agensi and installs these skills for you. If a payment is needed, your agent shows it to you first.
