Quality

Content

58%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The skill body is maximally concise and appropriately self-contained for its size, but it provides almost nothing actionable: the steps are vague hints, the validation requirement is stated as a goal with no mechanism, and the single code sample ('echo crlf') does not exercise CRLF parsing at all. Its main value is the constraint line ('MUST handle CRLF. MUST NOT assume LF only.'), which is clear but unsupported by execution detail.

Suggestions

Replace the placeholder 'echo crlf' with a real, meaningful command or script that actually tests CRLF behavior (e.g., creating a fixture file with \r\n endings and running the frontmatter parser against it).

Make each numbered step executable: specify which tests to run on Windows and the exact command, and how frontmatter parsing is verified (e.g., a concrete parser invocation and expected output).

Add an explicit validation checkpoint with a feedback loop: show the command to run, the expected result, and what to do when it fails, rather than the bare instruction 'Ensure parsing works.'

DimensionReasoningScore

Conciseness

The body is roughly 10 lines with zero padding and no explanation of concepts Claude already knows ('1. Run tests on Windows', 'MUST handle CRLF. MUST NOT assume LF only.'). Every token earns its place, matching the 'lean and efficient' anchor.

5 / 5

Actionability

'Run tests on Windows' and 'Verify frontmatter parsing' are high-level hints with no specifics (which tests, how to run them, how to verify), and the only command, 'echo crlf', is executable but does nothing relevant to CRLF parsing. This matches the 'minimal concrete guidance; high-level hints but missing the specific steps to execute' anchor rather than level 3, which requires some genuinely concrete (if incomplete) guidance.

2 / 5

Workflow Clarity

A rough two-step sequence exists ('1. Run tests on Windows' '2. Verify frontmatter parsing') but the steps are poorly defined and validation is absent — 'Ensure parsing works' states a goal without any checkpoint mechanism. This matches the anchor-2 example ('1. Open the document / 2. Make changes / 3. Save and close') rather than level 3, whose listed steps carry real, actionable content; the simple-skill exception does not apply because the single action is ambiguous.

2 / 5

Progressive Disclosure

This is a sub-50-line, single-purpose skill with no external references needed (no references/, scripts/, or assets/ bundle exists), and the content is well organized as heading, numbered steps, constraints, and a command block. The rubric's simple-skill scoring note allows a 5 here.

Description

47%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is a clean, specific trigger clause in third person with no fluff, but it is only half a description: it says when to use the skill and nothing about what the skill does. Adding a one-clause capability statement in third person would lift both completeness and specificity without costing token efficiency.

Suggestions

Add a third-person 'what' clause before the trigger, e.g., 'Runs and validates tests for Windows CRLF (\r\n) line-ending handling. Use when testing Windows CRLF line endings.'

Include natural trigger synonyms such as 'carriage return', 'newline characters', or '\r\n' so users phrasing the need differently still match.

State the concrete capability (verifying frontmatter/SKILL.md parsing under CRLF) so the description is distinguishable from generic Windows or text-processing skills.

DimensionReasoningScore

Specificity

The description names the domain concretely ('testing Windows CRLF line endings') but states no capability or action whatsoever — it is all trigger, no 'what'. This matches anchor 2 ('Names the domain but actions are minimal or generic'); it is not level 1 because the domain is specific rather than vague, and not level 3 because no concrete action is listed.

2 / 5

Completeness

Only the 'when' is present ('Use when testing Windows CRLF line endings') with no 'what' — exactly anchor 2's 'only when is present without what' case (cf. 'Use when working with documents'). The explicit, specific 'when' clause rules out level 1; the missing 'what' blocks level 3 and above.

2 / 5

Trigger Term Quality

'Windows', 'CRLF', 'line endings', and 'testing' are natural terms a user would say when needing this skill — good keyword coverage with only a few common variants missing (carriage return, newline, \r\n). Not level 5 because those synonyms/extensions are absent; not level 3 because coverage exceeds the single-generic-keyword pattern of 'Works with PDF files'.

4 / 5

Distinctiveness Conflict Risk

'CRLF line endings' is a distinct niche with clear triggers, giving minor conflict risk with closely related skills (general Windows testing, text/whitespace processing). Not level 5 because the absence of any capability statement leaves it less sharply distinguished than the anchor-5 examples; not level 3 because it is more specific than 'Works with document files'.
