The body is lean and terse — short labeled bullets like 'OBSERVE: Gather error, logs, repro steps, recent diffs' with no padding and no explanation of concepts Claude already knows, so every token earns its place.

Each protocol step is a concrete, specific directive (gather named artifacts, change one variable, re-run regression checks) plus sharp decision rules like 'Remove all print/console.log before commit'; as an instruction-only skill the guidance is actionable and complete, not vague.

The Root-Cause Protocol is a clearly sequenced six-step process with an explicit VERIFY validation checkpoint and feedback loops via Red Flags ('Re-open root cause'), matching the clear-sequence-with-validation anchor.

The skill is under 50 lines with well-organized sections and a single one-level-deep, clearly signaled reference to an existing file (references/bug-report-template.md), keeping short content inline and externalizing only the template.

The description lists multiple concrete actions — 'debugging crashes, tracing errors, diagnosing unexpected behavior, or investigating exceptions' — rather than vague language, matching the multiple-specific-actions anchor.

It explicitly states both what the skill does ('Troubleshoot systematically using the Scientific Method') and when to use it via an explicit 'Use when...' clause with concrete triggers.

It uses natural terms users would actually say ('debugging', 'crashes', 'errors', 'exceptions', 'troubleshooting'), reinforced by metadata keywords including 'fix bug' and 'crash', giving good coverage of common variations.

The debugging/troubleshooting niche is reasonably distinct, but broad triggers like 'error' and 'unexpected behavior' could plausibly overlap with other code or data skills, so it does not reach the clear-niche level.
