Lists specific concrete actions: 'Install a pre-commit hook that scans .specstory/history for secrets before commits' - describes exactly what it does with technical precision.

Clearly answers both what ('Install a pre-commit hook that scans .specstory/history for secrets') and when ('Run when user says...' with explicit trigger phrases).

Includes natural trigger phrases users would say: 'set up secret scanning', 'install specstory guard', 'protect my history', 'check for secrets' - covers multiple natural variations.

Highly distinctive with specific niche: targets .specstory/history specifically, mentions 'specstory guard' as a unique identifier, and focuses on pre-commit secret scanning - unlikely to conflict with generic security or git skills.

The skill includes some unnecessary explanation (e.g., 'Why Use Guard?' section explaining what AI sessions might capture, which Claude already understands). The content is mostly efficient but could be tightened by removing explanatory sections.

Provides fully executable bash commands, clear slash command table, and specific script paths. All examples are copy-paste ready with concrete flags and arguments.

Clear remediation workflow with explicit steps: open file → redact → re-run scan → commit. The 'How It Works' section provides clear sequencing, and the output examples show exactly what to expect at each stage.

Content is well-organized with clear sections, but everything is inline in one file. The detected patterns table and allowlist tuning could be separate reference files for a cleaner overview. However, the skill is moderately sized so this is acceptable.
