Conciseness

The body is lean throughout: Scope, Method, Threshold, and Reporting each earn their tokens, no concept Claude already knows is re-explained, and even the edge-case paragraphs (external contracts, boundary with Skill Instruction Integrity) deliver non-obvious policy rather than padding. Matches anchor 5 ("every token earns its place") and sits above anchor 4 because there is nothing identifiable to trim.

Actionability

The Method gives concrete, executable probes for both artifact types — "resolve every expression ... and ask what the expression evaluates to when a field is absent" and "an unset variable, an empty match, and a path containing a space" — and Reporting specifies exact deliverables including "Give the corrected line". Per the rubric's code-vs-instruction note, the absence of code is not penalized because the guidance is fully actionable and covers the common cases.

Workflow Clarity

The flow (read blocks as runtime reads them → compare against prose → check for divergent copies → apply the Threshold gate → report) is unambiguous, and the Threshold section acts as an explicit include/exclude checkpoint with concrete exemptions. This is a read-only analysis skill, so the destructive/batch validation cap does not apply, and the simple-skill exception (under 50 lines, single task, clear) is satisfied.

Progressive Disclosure

The skill is under 50 lines with no external references needed (no references/, scripts/, or assets/ bundles exist), and its four well-organized sections keep everything navigable inline. Per the rubric guideline, this scores 5 with just well-organized sections for a short single-file skill.

Specificity

The description states a concrete action ("Review a change to a code block ... for whether it works as printed") and enumerates specific targets ("a workflow, command, config file, or manifest embedded in documentation"). It stops short of anchor 5 because the sub-checks the skill actually performs (divergent copies, unresolvable placeholders) are not surfaced, leaving minor gaps in coverage.

Completeness

The "what" is clear (review copyable embedded blocks for whether they work as printed) and an explicit use clause exists ("Use as one lens in a code review run"). Not 5 because the when-clause is terse and lacks concrete trigger phrases (e.g., when a change touches embedded commands or config blocks in docs); not 3 because an explicit use clause is present, so the missing-when cap does not apply.

Trigger Term Quality

Good natural keyword coverage: "code block", "copy", "documentation", "config file", "manifest", "command", "code review". It falls below anchor 5 because common synonyms a user would naturally say — "snippet", "example", "copy-paste" — are absent, but it is well above anchor 3's single-keyword level.

Distinctiveness Conflict Risk

Clear niche (copy-paste-able blocks embedded in documentation) that is largely distinct, but "Use as one lens in a code review run" overlaps with general code-review skills, creating minor conflict risk on generic "review my PR" triggers.
