workflow-environment-ready — Preflight the Working Environment

Degree of freedom: MIXED. READY/BLOCKED verdict [HIGH freedom]; executed probes and never echoing secrets [LOW freedom — run exactly].

Long autonomous runs fail most expensively at the end — the work is done, then the build won't run, a service is down, or a key is missing. This skill front- loads that risk: prove the environment can build, test, and reach its dependencies before implementation starts.

Verify the environment can run the task, don't assume it. Every check is an executed command with observed output, not an inference from a config file.

How to reason

1. Detect — required runtimes, services, env names, gate commands
2. Probe — run each check; record observed output
3. Classify — cannot-run (env) vs runs-and-fails (code)
4. Verdict — READY / READY WITH NOTES / BLOCKED
