Diagnose the current OMC session or repo state using logs, traces, state, and focused reproduction

NewUpdated Oct 2, 2026

Debug

Use this skill when the user wants help diagnosing a current OMC/Claude-Code session problem, workflow breakage, or confusing runtime behavior.

Goal

Find the real failure signal quickly and explain the next corrective step.

Workflow

  1. Read the user’s issue description carefully.
  2. Inspect the most relevant local evidence first:
    • trace tools
    • state tools
    • notepad / project memory when relevant
    • failing tests or commands
  3. Reproduce the issue narrowly if possible.
  4. Distinguish symptoms from root cause.
  5. Recommend the smallest next fix or verification step.

Rules

  • Prefer real evidence over guesses.
  • Use the trace/state surfaces when the issue involves orchestration, hooks, or agent flow.
  • If the issue is actually a product/runtime bug rather than app code, say so plainly.
  • Do not prescribe broad rewrites before isolating the failure.
  • Tag temporary debug output [DEBUG-<4hex>]; cleanup is then a single grep.
  • Redact secrets from logs and traces before they leave the session.
  • If the failure traces to a missing or wrong seam, say so as the finding and point at refit or architecture-survey — the environment lesson outlives the fix.

Output

  • Observed failure
  • Root-cause hypothesis
  • Evidence for that hypothesis
  • Smallest next action

Summary

This skill guides an AI agent to diagnose OMC/Claude-Code session problems by inspecting logs, traces, state tools, and reproducing issues narrowly. It emphasizes finding root causes through evidence-driven investigation rather than speculation, with clear rules for redacting secrets, avoiding broad rewrites, and pointing to architectural issues when appropriate.

Use Cases

  • Diagnose Claude-Code session failures
  • Investigate workflow breakage in OMC
  • Isolate root cause from logs and traces
  • Reproduce and debug runtime behavior issues
  • Distinguish symptoms from root causes in agent flow

Quality Notes

  • Clear workflow with numbered steps (inspect, reproduce, distinguish, recommend)
  • Strong emphasis on evidence-driven diagnosis and avoiding speculation
  • Practical rules for managing debug output (tagged cleanup) and secret redaction
  • Explicitly acknowledges when issues are product bugs vs. app code problems
  • References related skills (refit, architecture-survey) for appropriate escalation
  • Output format well-defined (failure, hypothesis, evidence, next action)
  • Good guidance on scope — avoids broad rewrites before isolation
