Event Producer & Consumer Ownership
Make event pipelines release producers, transfer consumer ownership, preserve ordering, retry safely, and recover abandoned work. This bundle combines async-generator finalization with rebalance races, outbox delivery, lost and out-of-order events, queue retries, poison messages, and stuck leases. Use it when cancellation or reassignment can leave duplicate, missing, late, or permanently owned event work.
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 stale consumer ownership, rebalance races, old-generation commits, lease-loss overlap, late callbacks, and ack/commit authority bugs.
Repair systems that commit database changes but lose or duplicate the events that should follow.
Trace and repair events that disappear between producers, outboxes, brokers, consumers, retries, checkpoints, and databases.
Repair systems where delayed or out-of-order events overwrite newer data or move workflows backward.
Repair background-job retry drift in a repository using Cursor.
Repair queue consumers where one bad message loops forever, blocks healthy traffic, or repeatedly crashes the same partition.
Repair workers that leave jobs stuck, process the same task twice, or let expired owners write results.

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.
