Conciseness

The body is pure instruction: a one-line purpose ("Validate the entire project (or a specific module) against docs/ARCHITECTURE.md"), a scope line ("Scope: $ARGUMENTS (if empty, validate all src/modules/)"), one executable script, and a table spec. No concept explanations, no padding; nothing to trim, so it exceeds anchor 4.

Actionability

The 12-check bash block is copy-paste ready with concrete grep/find/wc pipelines, --include filters, 2>/dev/null guards, and PASS fallbacks, plus an explicit output format ("| Check | Status | Occurrences |" and "Overall score: X/12 checks passing"). Fully executable with no gaps.

Workflow Clarity

The sequence run checks → produce summary table → report "X/12 checks passing" is clear, and the checks embed their own pass/fail output. Not 5: PASS/FAIL criteria for the count-based checks (8: any types, 11: debug artifacts) are implicit, and there is no guidance on presenting failures or next steps. Not 3: the checks are read-only validations with an explicit reporting structure, so no destructive-step feedback loop is missing.

Progressive Disclosure

Everything lives in one "## Automated Checks" section with no external references, which is appropriate for a single-script skill and makes navigation trivial. Not 5: the body runs ~59 lines — just past the compact-skill threshold — with no per-check manifest or PASS/FAIL criteria organizing the 12 checks, though no bundle files are needed.

Specificity

"checking if code follows ARCHITECTURE.md patterns" and "runs automated conformance checks" name the domain plus 1-2 actions, but they restate a single capability rather than listing several distinct ones (the 12 checks, summary table, and scoring appear only in the body). Fits anchor 3; not 4 because coverage of concrete actions is not several and comprehensive.

Completeness

Both elements are explicit: "Use when checking if code follows ARCHITECTURE.md patterns" answers when, and "runs automated conformance checks" answers what. Below 5 because the what is terse and the when offers only one trigger phrasing rather than concrete trigger phrases.

Trigger Term Quality

"ARCHITECTURE.md patterns" is a precise, literal trigger users would naturally say, and "conformance checks" adds a relevant keyword. Not 5 because common synonyms like "architecture review", "compliance", or "coding standards" are missing; better than anchor 3's single generic keyword.

Distinctiveness Conflict Risk

The description is anchored to a specific project artifact ("ARCHITECTURE.md patterns") and a niche activity ("conformance checks"), making it mostly distinct with only minor overlap risk against generic code-review skills. Not 5 because a plain "review my code" request could still plausibly trigger it.
