Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 13, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · f9308db

Ran a python39-compat CI-failure prompt through it: it pointed straight at the datetime.UTC / bare X|Y union trap and warned that ruff's UP017 autofixer will silently revert the fix on the next lint run — a gotcha a generic debugging answer would miss entirely.

What Night Market Debugging Playbook does

A 10-row symptom-to-cause-to-fix table for this repo's own Claude Code plugin/hook failures (ModuleNotFoundError on commit, python39-compat breaks, silent no-op hooks, swallowed scanner exceptions), each row citing the commit hash that fixed it. Triggers when a check fails unexpectedly in the night-market repo; explicitly defers to sibling skills for routine test/lint/release runs or environment setup.
