Conciseness

Mostly efficient — a ~40-line body with concrete steps and an example table — but includes unnecessary padding: the persona framing ('You are not a skill or an agent. You are a piece of software—a linter, called Dale') and two overlapping sections ('# Dale rules engine' vs '# Rules Engine') that restate where rules live. Not anchor 2 since there is no concept-teaching filler; not anchor 4 because the duplicated sections and persona talk could be trimmed.

Actionability

The procedure is concrete: per-rule loop with Todo tracking, explicit narration lines, 3a/3b branching, and a copy-ready example output table with columns (Line, Rule, Message, Offending Text). Minor gaps keep it from anchor 5: rule interpretation details are delegated to a schema file with no example rule, and the table example covers only one row.

Workflow Clarity

The sequence is clearly listed (read reason -> check document -> record violation or move on -> print table), but this is a batch operation (looping over every rule in ./rules) with no validation checkpoints — no handling of malformed rule files, no confirmation against the rule schema, and ambiguous handling of rule files that fail to parse. Per the guideline capping batch workflows without validation at 3, this cannot score 4.

Progressive Disclosure

The body has section headers and stays lean, but its references are problematic: it cites '/references/rule-schema.yml' and '/rules' with inconsistent path notation ('./rules' vs 'the skill /references/...'), and no such bundle files exist in this skill, so navigation to the detailed material is unclear. This matches anchor 3 ('references present but not clearly signaled') rather than anchor 4's 'references mostly clear'.

Specificity

The description names its domain ('a markdown file is edited in the docs/ directory') but states no action whatsoever — it never says what the skill does (lint, check rules, report violations). It sits above the entirely-vague anchor 1 ('pure abstract language') because it names a concrete target, but below anchor 3, which requires 1-2 concrete actions.

Completeness

Only the 'when' is present ('Any time a markdown file is edited in the docs/ directory') with no 'what' — the skill's actual function is never stated. This matches anchor 2 exactly ('only when is present without what'), and is not anchor 3, which requires a clear 'what'.

Trigger Term Quality

It includes some natural terms ('markdown file', 'edited', 'docs/ directory'), but misses common variations users would say — 'documentation', '.md', 'updated', 'changed', 'docs'. Not anchor 2 (only generic keywords like 'Works with files') because 'markdown' and 'docs/' are domain-specific; not anchor 4 because synonym coverage is thin.

Distinctiveness Conflict Risk

The trigger is scoped narrowly (markdown edits in docs/), making it mostly distinct with minor overlap risk against other docs-related skills. It does not fully reach anchor 5 because the unstated function leaves ambiguity about which doc-editing skill should fire.
