The body is information-dense and avoids explaining concepts Claude already knows, but at ~320 lines with a full worked example, an anti-pattern table, a limitations section, and a verbatim sample PR comment, several passages could be tightened without losing substance — the 'mostly efficient but could be tightened' anchor rather than the lean level 3. It does not rise to the verbose, concept-explaining level 1 because nearly every token concerns non-obvious domain specifics.

Provides executable, complete code (`dedupe`, `priority`, `validate_waiver`), a concrete CI-integration YAML with real `gh pr comment` flags and EPSS/KEV download commands, and a copy-paste report template — matching 'fully executable code/commands; specific examples; copy-paste ready' and clearly above the pseudocode level 2.

A clear 7-step sequence anchored by the `collect -> normalize -> dedupe -> enrich -> waive -> verdict -> report` diagram, with explicit validation checkpoints for a batch/gate operation — halt on `NO_SCANNER_OUTPUT`, halt when a configured scanner produced no artifact, and surfacing rejected waivers rather than silent no-ops — meeting the 'clear sequence with explicit validation steps' anchor and not the level 2 case with implicit checkpoints.

The body is a well-organized overview that links out one level deep to three real, verified bundle files — `references/finding-normalization.md`, `references/cve-enrichment.md`, and `references/waiver-schema.md` (all present) — each clearly signaled at the relevant step, matching 'clear overview with well-signaled one-level-deep references' and not the inline-heavy or poorly-signaled level 2.

Lists multiple concrete actions — "Merges two or more security scanner reports", "Normalizes each report into one common finding format", "deduplicates on a per-domain key", "validates a waiver ... file, rejecting any missing `expires:` / `approved_by:` / `reason:`", "enriches CVE findings with EPSS ... and CISA KEV", "applies a `fail_on` severity threshold to emit BLOCK or PASS plus a bucketed pull-request comment" — matching the 'lists multiple specific concrete actions' anchor rather than the partial level 2.

Explicitly answers both what (the full collect-through-report pipeline) and when via an explicit "Use when ..." clause, satisfying the 'clearly answers both what AND when with explicit triggers' anchor; not the level 2 case where the trigger is only implied.

Opens with a natural third-person "Use when you need a single BLOCK or PASS decision from multiple scanners instead of reading N separate reports", covering real phrasings a user would say; not merely jargon, and clearly above the 'some relevant keywords but missing common variations' level 2.

Carves a clear niche and actively de-conflicts by naming sibling skills — "To run a single scanner instead use semgrep-rules, codeql-queries, bandit-python, or gosec-go; this runs after them to merge output - the cross-scanner gate, not a single-scanner wrapper" — making overlap with those skills unlikely, matching the 'clear niche with distinct triggers' anchor.
