Conciseness

The body is a lean operational router — a dense routing table plus a 7-step workflow — with no explanation of concepts Claude already knows and every line actionable ('Run python3 scripts/detect_stack.py --root .'); not 4 because no section could be trimmed without losing operational content.

Actionability

Commands are concrete and verified against the bundle ('python3 scripts/detect_stack.py --root .', 'scripts/upsert_section.py --file <path> --content-file <ref> --hash --substitute pm=<pm>', the exact marker pair) with a manual fallback for missing python3. Not 5: step 3's '--dry-run', refresh, and '--remove' modes are not attributed to any script — they exist only on upsert_section.py, not detect_stack.py — and the source of the '<pm>' substitution value is unstated.

Workflow Clarity

Clear 7-step sequence with safety checkpoints: git-status inspection ('Never overwrite uncommitted user changes'), a confirmation gate ('Never write before confirmation'), marker confinement ('Never alter text outside the markers'), and idempotency ('Re-running on unchanged code is byte-identical'). Not 5: no explicit post-write validate-and-retry feedback loop for these multi-file batch writes, though dry-run support and hash reporting partially cover verification — enough to stay above the cap-at-3 case.

Progressive Disclosure

The routing table signals one-level-deep references clearly, and every referenced path (14 reference files, both scripts, both assets) verified to exist on disk. Not 5: three bundle files — references/apply-plan.md, references/repository-workflow.md, and scripts/apply_guidelines.py — are never referenced from the body; repository-workflow.md even self-describes as 'Read this during every setup or refresh' yet is unreachable via SKILL.md navigation.

Specificity

Names four concrete actions spanning the full pipeline — 'detects tech stack layers, confirms with the user, generates tailored guidelines from modular references, and links them from AGENTS.md without overwriting user content' — matching the comprehensive anchor, but the first-person trigger phrase 'detect my stack' incurs the rubric's mandated 1-point voice penalty (base 5, adjusted to 4).

Completeness

Explicitly answers both: 'what' (detect, confirm, generate, link, 'without overwriting user content') and 'when' ('Use when asked to generate or set up coding guidelines... on first use in a codebase') with six concrete trigger phrases, mirroring the anchor-5 example structure.

Trigger Term Quality

Covers natural user phrasing comprehensively — 'generate or set up coding guidelines', 'detect my stack', 'generate AGENTS.md rules', 'create stack-specific conventions', 'set up agent guidelines', 'configure coding guidelines for this repo' — including synonyms (guidelines/rules/conventions) and the concrete artifact name AGENTS.md; not 4 because no common variation is obviously missing.

Distinctiveness Conflict Risk

'Excludes general code review, linter/formatter configuration, or CI pipeline setup' draws explicit boundaries, and triggers center on the niche AGENTS.md / stack-specific conventions artifact, so overlap with adjacent skills is minimal.
