Async Iterator & Stream Cleanup
Stop async iterators and streaming adapters from leaking producers, cursors, descriptors, subscriptions, or buffered work after break, cancellation, failure, or shutdown. This bundle combines terminal-state ownership, backpressure, partial-read protection, orphan reconciliation, and observability. Use it when a consumer exits correctly but upstream tasks and resources continue running or publish late data.
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 async-generator cleanup leaks after early break, return, throw, timeout, cancellation, or pending-next races.
Repair lost cancellation signals, orphaned async work, retry-after-cancel bugs, stale completions, and unclear request-vs-durable task lifetimes.
Repair unbounded stream/queue pipelines, ignored backpressure, slow-consumer memory growth, retry amplification, and cancellation leaks.
Repair partial reads, truncated frames, stream-chunk/message confusion, early EOF acceptance, and stale decoder state.
Repair file descriptor and handle leaks from files, streams, watchers, pipes, subprocesses, early returns, retries, errors, and cancellations.
Safely detect, verify, quarantine, and clean up orphaned cloud resources after failed provisioning, deletions, or database drift.
Repair apps that lose jobs, events, or writes when containers restart, deployments roll, or processes receive termination signals.
Automatically add production-ready logging, metrics, health checks, and error monitoring to existing apps.

Repair Async Generator Cleanup Bugs
Example session with this skill installed
Our TypeScript service wraps a broker subscription in two async-generator adapters. Breaking from for-await closes the outer generator, but the inner subscription keeps receiving messages and its heartbeat timer survives. A pending next() can also resolve after cancellation and publish one more value. Repair locally with a fake subscription and controlled promises. Preserve message order, buffer size, retry behavior, and timeout values; do not connect to the broker.
- Read your context and instructions
- Compiled the repair async generator
Cleanup leak found. The adapter forwards next but not return, so breaking from for-await leaves the source producer and subscription alive. The repair forwards all terminal operations, makes finalization single-owner, cancels the pending read, preserves the original error, and verifies that no value or resource survives termination.
