Agent Introspection Debugging

Use this skill when an agent run is failing repeatedly, consuming tokens without progress, looping on the same tools, or drifting away from the intended task.

This is a workflow skill, not a hidden runtime. It teaches the agent to debug itself systematically before escalating to a human.

When to Activate

• Maximum tool call / loop-limit failures
• Repeated retries with no forward progress
• Context growth or prompt drift that starts degrading output quality
• File-system or environment state mismatch between expectation and reality
• Tool failures that are likely recoverable with diagnosis and a smaller corrective action

Scope Boundaries

Activate this skill for:

• capturing failure state before retrying blindly
• diagnosing common agent-specific failure patterns
• applying contained recovery actions
• producing a structured human-readable debug report

Do not use this skill as the primary source for:

• feature verification after code changes; use verification-loop
• framework-specific debugging when a narrower ECC skill already exists
• runtime promises the current harness cannot enforce automatically

Four-Phase Loop

Phase 1: Failure Capture

Before trying to recover, record the failure precisely.

Capture:

• error type, message, and stack trace when available
• last meaningful tool call sequence
• what the agent was trying to do
• current context pressure: repeated prompts, oversized pasted logs, duplicated plans, or runaway notes

Phase 2: Root-Cause Diagnosis

Phase 3: Contained Recovery
