Health Check Command

Perform a comprehensive session health audit across all six failure dimensions.

Execution

1. Load skill and heuristics:

   • Read ${CLAUDE_PLUGIN_ROOT}/skills/failure-detection/SKILL.md for the failure pattern overview.
   • Read ${CLAUDE_PLUGIN_ROOT}/skills/failure-detection/references/detection_heuristics.md for the specific signals to evaluate.
   • Read ${CLAUDE_PLUGIN_ROOT}/skills/failure-detection/references/severity_schema.md for severity levels and report format.

2. Load previous report (if exists):

   • Read .claude/watchdog-report.md if it exists. Note any previously flagged issues to check if they are resolved or worsening.

3. Evaluate all six dimensions:

   Spec Drift: If artifacts/ directory or any spec file exists, compare recent code changes against spec requirements. Look for files with no spec coverage and requirements with no code. Assign healthy/warning/critical.

   Sycophantic Confirmation: Review the current session for claims of success. For each claim, verify a corresponding Bash command ran the actual test/build/lint. Check for agreement with contradictory requirements. Assign severity.

   Silent Failures: Review recent Bash command outputs for error indicators that may have been overlooked — errors in passing builds, zero-test runs, permission issues. Assign severity.

   Tool Selection: Check recent tool usage for suboptimal patterns — Bash used for tasks that have dedicated tools, Write used where Edit would suffice. Assign severity.

   Agentic Loops: Check for repeated edits to the same file (3+ times), repeated Bash commands, or alternating approaches. Assign severity.

   Context Degradation: Test your own recall of the original requirements or task. Can you list all requirements? Have you contradicted any earlier decisions? Assign severity.

4. Write report:

   • Create .claude/ directory if it does not exist.
   • Write the health report to .claude/watchdog-report.md following the template in severity_schema.md.
   • Set the trigger to /health-check.

5. Present summary:

   • Display the dimension ratings table.
   • If any dimension is critical, present it prominently with recommended actions.
   • If all dimensions are healthy, confirm the session is on track.

Output

A summary of the health check results with per-dimension severity ratings, followed by specific recommendations for any warning or critical findings. The full report is persisted at .claude/watchdog-report.md.
