Async Pipeline Ownership & Backpressure
Control asynchronous work from producer pressure through cancellation, retries, worker ownership, shutdown, and cleanup. This bundle repairs cancellation propagation and stream backpressure, stuck job leases, shutdown data loss, queue retry contracts, partial batches, background-job implementation, and orphaned-resource reconciliation. Use it when work survives too long, multiplies under pressure, or disappears during partial failure and restart.
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 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 workers that leave jobs stuck, process the same task twice, or let expired owners write results.
Repair apps that lose jobs, events, or writes when containers restart, deployments roll, or processes receive termination signals.
Repair background-job retry drift in a repository using Cursor.
Repair bulk APIs, imports, and workers where one failed item hides successful work or triggers unsafe full retries.
Automatically add background jobs, queues, and scheduled tasks to existing apps.
Safely detect, verify, quarantine, and clean up orphaned cloud resources after failed provisioning, deletions, or database drift.

Repair Cancellation Propagation
Example session with this skill installed
Our Next.js/TypeScript API uses AbortController at the route layer, but the signal is not passed through the service to our fetch-based vendor client or Prisma wrapper. When a browser cancels a long export request, the vendor call and database aggregation continue for 20–40 seconds. Promise.all starts four child operations; if one fails, two others keep running. A retry helper can start another vendor request even after the route was cancelled. Repair cancellation propagation locally with deterministic tests. Do not call the live vendor, query production data, kill production jobs, or assume an already accepted vendor request was undone by local cancellation.
- Read your context and instructions
- Compiled the repair cancellation propagation
Cancellation propagation gaps found. The request AbortSignal is lost at service boundaries, vendor calls ignore it, sibling work can outlive failure, and retry may start after cancellation. The repair forwards cancellation through request-owned work, adds structured cleanup and retry suppression, protects durable handoff boundaries, and adds deterministic cancellation tests. Remote provider and production DB cancellation remain unverified.
