Individual skill
go-cli-process-control
Execute and supervise external programs safely from Go CLIs with explicit arguments, typed failure classification, working directories, environments, bounded streams, deadlock-safe pipes, contexts, timeouts, signals, platform adapters, descendant cleanup, runner seams, and lifecycle tests. Use when wrapping a command, diagnosing start or exit failures, hangs, deadlocks, or orphan processes, or implementing cancellable cross-platform CLI workflows.

# Go CLI Process Control
Treat child-process lifecycle as correctness. Observe the terminal result,
propagate cancellation, and clean up every process, pipe, and temporary resource.
## Core Workflow
1. Define the child executable, argv, environment, directory, streams, and success contract.
2. Use an explicit shell only when shell semantics are actually required.
3. Inject a runner boundary and propagate the caller's context.
4. Observe startup and completion; preserve status and useful redacted stderr.
5. Bound captured output, cancellation, and shutdown time.
6. Account for descendants and wait for every pipeline stage.
7. Test missing tools, bad exits, malformed output, cancellation, signals, and cleanup.
