debugging SKILL.md skillA

debugging from sentimony/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add sentimony/skills/debugging@v1.1.2

Pins v1.1.2 in mdr.lock. Pin the fingerprint instead.

You MUST use this when investigating bugs, regressions, failing tests, build or integration failures, flaky behavior, performance anomalies, or other unexpected technical behavior.

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

# Debugging

`debugging` is the canonical root-cause-first methodology for unexpected technical
behavior. It answers:

```text
What evidence explains why this failure occurs,
where it originates, and what minimal change
removes the root cause?
```

## Scope and routing

Enter through `scope-triage` for a bug or failure request. Use this skill to explain WHY
the behavior is broken. Keep product redesign, new architecture, and materially changed
behavior in `scope-triage`, followed by `plan-crafting` when a plan is appropriate.

This skill owns:

```text
symptom -> reproduction or characterization -> evidence -> boundary
  -> falsifiable hypothesis -> discriminating test -> supported cause
  -> regression evidence -> causal fix -> targeted verification
```

It does not own browser automation, framework API instructions, implementation planning,
final completion verification, code review workflow, UI design, workspace setup, or agent
orchestration. Use the composition table below when one of those capabilities is needed.

## Root-cause invariant

```text
NO FIX WITHOUT SUFFICIENT ROOT-CAUSE EVIDENCE
```

How to install

The exact contents, by fingerprint
mdr add sentimony/skills/debugging@sha256:6611a74760d01c71

The line at the top of this page pins the label v1.1.2, 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.
