improve: enhance debugger agent

[davila7]

Automated Component Improvement

Changes

• Add model: claude-sonnet-4-5 — Production debugging requires capable reasoning; previously relied on inherited default which could resolve to Haiku.
• Remove fictional JSON blocks — Deleted the "Communication Protocol / Debugging Context" JSON block and the "Progress tracking" JSON block. These described an inter-agent messaging bus that does not exist in Claude Code's subagent model, teaching the model to emit JSON instead of using tools.
• Replace generic 3-phase workflow with 6-step fault-localization decision tree — Steps now encode the scientific debugging method: reproduce → confirm observed vs expected → generate ranked hypotheses → falsify most likely hypothesis → fix + regression test → document root cause. Each step has a concrete action.
• Add Observability-Driven Debugging section — Actionable guidance for the three pillars (distributed traces, correlated logs with ±2 min window and correlation ID, change correlation via git log --since) that applies directly to all three production examples in the description.
• Trim description — Reduced from ~2300 chars to ~1200 chars by tightening each <commentary> to a single trigger-condition sentence. Reduces token cost at agent-selection evaluation time.
• Remove rubber duck debugging — Human metacognitive technique; not executable by an LLM agent.

Research Summary

The component had correct tooling and good multi-shot examples, but included fictional inter-agent JSON communication blocks that could cause the model to emit JSON instead of using tools, a generic 3-phase workflow indistinguishable from other agents, and no observability-driven guidance despite all examples being production incidents. The description was also 2x the recommended token ceiling.

Validation

• component-reviewer: PASSED
  • Valid YAML frontmatter with all required fields (name, description, tools, model)
  • Name is kebab-case: debugger
  • No hardcoded secrets or absolute paths
  • No fictional JSON blocks present
  • Fault-localization decision tree present
  • Observability-Driven Debugging section present
  • Description within target length

Summary by cubic

Enhances the debugger agent for clearer, faster production debugging. Adds a 6-step fault‑localization flow, observability-first guidance, and standardizes the model to claude-sonnet-4-5.

• Refactors
  • Replaced generic workflow with a 6-step fault-localization decision tree and added observability-driven debugging (traces, correlated logs, change correlation).
  • Set model: claude-sonnet-4-5 in frontmatter and trimmed description ~50% to reduce token cost and improve consistency.
  • Removed fictional JSON protocol/progress blocks and non-executable “rubber duck” content to prevent JSON emission and encourage proper tool use.
  • Area: components (cli-tool/components/agents/development-tools/debugger.md). No new components; no docs/components.json regeneration needed. No new environment variables or secrets.
