Silent Failure Review
Detection
| ID | Pattern | Fix |
| --- | -------------------------------- | --------------------------------------- |
| SF1 | catch (e) {} | catch (e) { logger.error(e); throw } |
| SF1 | catch (e) { console.log(e) } | Show user feedback + log context |
| SF2 | .then(fn) without .catch() | Add .catch() or use try/catch |
| SF2 | async () => { await fn() } | Wrap in try/catch, handle error |
| SF3 | No error UI states | Add error boundary, feedback component |
| SF4 | value ?? defaultValue silently | Log when using fallback |
| SF4 | data?.nested?.value | Check and report if unexpected null |
| SF5 | catch { return defaultValue } | Log root cause before returning default |
| SF5 | config.x \|\| fallback | Validate config, warn on missing keys |

Judge a SKILL.md against craft axes (single responsibility, description distinctiveness, imperative voice, verifiable completion, calibration, progressive disclosure) and apply the fixes the audit surfaces. Do not use for format-presence-only checks (use reviewer-prompt) or reproducibility loops (use /tuning).

Extract repository spec while detecting bugs, spec gaps, and consistency drift via dual-purpose documentation. OUTCOME.md-axis question-driven exploration with ephemeral output. Do NOT use for code review (use /audit or /polish), feature implementation (use /code), planning only (use /think), or single-bug fix (use /fix).
