Context Debugging

Check context first. It's the highest-ROI debugging target for agent failures.

The Boundary Rule

Agent failing, not an obvious code bug?         →  Use this skill.
Agent has never worked (greenfield)?            →  Use context-cartography.
Infrastructure error (API 500, timeout)?        →  Not a context problem.
Code bug in the harness (template, parsing)?    →  Use systematic-debugging.

The Triage Flow

Step 0 — VERIFY ACTUAL CONTEXT
