typescript-async-concurrency SKILL.md skillA
typescript-async-concurrency from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/typescript-async-concurrency@git:20261029.32a42cePins git:20261029.32a42ce in mdr.lock. Pin the fingerprint instead.

Use when designing, implementing, debugging, or reviewing asynchronous TypeScript workflows: promises, async/await, typed HTTP boundaries, bounded concurrency, queues, retries, cancellation, timeouts, mutexes, debouncing, async iterators, or race conditions where lifecycle, result ordering, failures, and cleanup must be explicit.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TypeScript Async and Concurrency ## Define the lifecycle 1. Inspect the project's runtime, module mode, HTTP/client abstractions, lint rules, and test tooling. 2. Identify dependent versus independent operations and when each operation actually starts. 3. Define maximum in-flight work, output ordering, fail-fast versus settle-all results, retry policy, and cancellation behavior. 4. Identify owners of timers, listeners, locks, streams, and pending caller promises. 5. Separate a concurrency limit from a requests-per-time rate limit; specify both when required. 6. Define whether returning to a caller requires started work to finish, or whether background cleanup continues. ## Choose coordination semantics | Requirement | Starting mechanism | Remember | | --- | --- | --- | | Later operation needs an earlier result | Sequential `await` | Preserve dependency and error propagation | | All independent results required | `Promise.all` | Rejection does not cancel siblings | | Every success/failure must be reported | `Promise.allSettled` | Inspect each discriminated outcome | | First settlement decides outcome | `Promise.race` | Losers keep running unless separately cancelled | …

How to install
mdr add lu1sdv/skillsmd/typescript-async-concurrency@sha256:dd239b0859b8132dThe line at the top of this page pins the label git:20261029.32a42ce, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
