Debug+

debug+ — Systematic Debugging with Scout Context

Wraps superpowers:systematic-debugging. Requires superpowers to be installed.

No phase prerequisite — invoke from any skill chain phase when you encounter a bug, test failure, or unexpected behavior.

Before You Begin

This skill adds scout-mandated context harvesting on top of the base debugging skill:

1. Scout context — always map the affected code area via the scout agent before debugging
2. Environment awareness — detects test infrastructure, dependencies, and recent changes
3. Constitutional awareness — loads active enforcement rules from session context

Procedure

Phase A: Harvest Context

1. Reproduce the issue — run the failing command or test and capture the exact output.

2. Invoke the scout agent to map the affected area:

   Agent(subagent_type="scout", prompt="Map the codebase around [affected files/modules]. Focus on: related functions, callers, test files, and recent changes.")
   

3. Identify:

   • The exact failure symptom (error message, wrong output, crash)
   • The code path that produces the symptom
   • Recent changes that may have introduced the issue
   • Related test coverage
   • Active enforcement rules from session context (see session-start output)

Phase B: Investigate (delegate to superpowers:systematic-debugging)

1. Invoke superpowers:systematic-debugging with the gathered context.

2. Follow the systematic debugging process:

   • State the hypothesis before investigating
   • Verify the hypothesis with evidence (command output, file reads)
   • If the hypothesis is wrong, state why and form a new one
   • Show the evidence at each step

Phase C: Report Findings

1. Produce a finding summary:

   ## Investigation Report
   
   ### Symptom
   [Exact failure description]
   
   ### Root Cause
   [What caused the issue]
   
   ### Evidence
   - [Evidence 1: command output or file content]
   - [Evidence 2: ...]
   
   ### Fix
   [Specific change needed to resolve the issue]
   

2. If the fix is straightforward, implement it and run the relevant tests. If the fix requires a larger change, return to the current phase with the finding.

Skill Chain

/debug+ has no phase prerequisite — invoke it from any phase when you need to debug a bug or investigate unexpected behavior. After resolving the investigation, return to your current phase.

Completion

Report one of these states when the skill finishes:

• DONE — Root cause identified and fix applied with passing tests.
• DONE_WITH_CONCERNS — Root cause identified but fix has side effects or needs review.
• BLOCKED — Cannot reproduce the issue or insufficient context to diagnose.
• NEEDS_CONTEXT — Need user input to reproduce the issue or understand expected behavior.
