python-concurrency SKILL.md skillA
python-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/python-concurrency@git:20261103.8277e03Pins git:20261103.8277e03 in mdr.lock. Pin the fingerprint instead.

Use when choosing or debugging Python threads, process pools, asyncio tasks, TaskGroup cancellation or early termination, timeouts, bounded queues, worker shutdown, deadlocks, GIL assumptions, free-threaded CPython, multiple interpreters, or AnyIO/Trio cancellation differences. Targets the latest stable CPython baseline.
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
# Python Concurrency ## Route the work | Situation | Default and reference | |---|---| | Blocking calls, CPU work, shared state, executor hangs | Start sequential; use bounded threads for blocking I/O and consider processes for substantial GIL-bound CPU work. [Execution and coordination](references/execution-and-coordination.md) | | Async-compatible I/O, task failure, group early exit, deadlines or growing backlog | Use the existing loop, structured task ownership and bounded admission. [Async lifecycle](references/asyncio-lifecycle.md) | | Runtime upgrade, free threading or multiple interpreters | Check the actual build, start method and dependency compatibility. [Runtime versions](references/runtime-versions.md) | Load the relevant reference before changing its mechanism. Target **CPython 3.15.2** (stable baseline checked 2026-11-03); recheck Python.org on a future refresh. When applying this skill to an older project, preserve its declared support policy. ## Workflow 1. **Classify and measure.** Identify blocking I/O, async-compatible I/O, pure-Python CPU work and native code that releases the GIL. Include startup, …

How to install
mdr add lu1sdv/skillsmd/python-concurrency@sha256:c9e531c8c7945396The line at the top of this page pins the label git:20261103.8277e03, 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.
