Mostly lean and assumes Claude's competence, but a few explanatory asides ('Faster local feedback than CI-only scanning', 'fetch-depth: 0 is critical - without full git history...') and inline time-sensitive version pins (v8.24.2, v8.19.0+) that aren't isolated in a deprecated section keep it from a 3.

Executable bash, YAML, and TOML blocks throughout (install, scans, config, pre-commit, CI workflow) are copy-paste ready with specific flags and report formats, matching the fully-executable anchor.

An explicit 8-step sequence with validation emphasis — MANDATORY false-positive triage with Re-review-date, rotate-before-scrub, baseline gating — plus an anti-patterns table and a destructive-history rotation workflow with audit/feedback checkpoints.

SKILL.md is an overview that points one level deep to a real references/custom-rules-and-triage.md, clearly signaled at Step 4, Step 5, and the worked example; the referenced file exists and holds the deferred detail.

Lists multiple concrete actions — `gitleaks git`, `gitleaks dir`, `gitleaks stdin`, custom `[[rules]]` with regex/entropy/keywords, allowlists, pre-commit hook, GitHub Action, and baseline file — matching the 'multiple specific concrete actions' anchor.

Explicitly answers what (configures/runs gitleaks scanning with its modes, rules, and integrations) AND when via the 'Use when the team needs OSS secret scanning at commit time + CI gate' clause.

Natural terms a user would say ('secret scanning', 'commit time', 'CI gate', 'gitleaks') give good coverage; not below because the common variations are present rather than partially missing.

A clear gitleaks-specific niche with distinct triggers, explicitly distinguished from sister scanners (trufflehog) and the rotation runner, so unlikely to fire for the wrong skill.
