Diagnose one bug with hypotheses and runtime evidence before fixing. Use when "debug this error" or behavior is unexpected. FE↔BE mismatch → debug-fe-be-integration. Bug to PR → workflow-fix-and-ship. Sentry backlog → debug-sentry-monitor.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Debug Error Skill **Degree of freedom: MIXED.** Root-cause judgment `[HIGH freedom]`; the red feedback loop and verify-green re-run `[LOW freedom — run exactly]`. Systematic approach to debugging errors and unexpected behavior. Works with any project. ## How to reason 1. **Observe** — exact symptom, stack, environment, first-seen 2. **Interpret** — crash site vs producer; FE / BE / integration / data 3. **Classify** — null-access / contract / env / race / unknown 4. **Severity** — prod-wide auth break outranks a single-user edge ## Worked example > **Observe:** `TypeError: Cannot read property 'email' of undefined` on `/account` after signup. > **Interpret:** crash is in the profile card; API returns `null` for incomplete onboarding. > **Classify:** data bug — producer returns null, consumer assumes an object. > **Fix:** handle the onboarding-null at the producer contract + UI empty state; do not `?.` the crash site only. ## Self-critique before reporting - **Red loop first** — a failing command existed before the hypothesis - **Root, not symptom** — no `?.` / swallowed catch as the sole fix - **Green loop** — the same command was re-run and passed …

How to install
mdr add kensaurus/cursor-kenji/debug-error@sha256:88c2e76521f2d6f4The line at the top of this page pins the label git:20260926.c7354ac, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
