Quality

Content

45%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 body is perfectly lean but content-free: 'Do the thing.' gives Claude no actionable or workflow-level guidance, making the skill unusable in practice. Only its trivially clean structure avoids a floor score on every dimension.

Suggestions

Replace 'Do the thing.' with concrete, executable guidance — actual commands, code, or specific instructions for the task.

If the task involves multiple steps, sequence them explicitly with a validation checkpoint; even a single-step skill must state its one action unambiguously.

State expected inputs and outputs so Claude can verify it performed the task correctly.

DimensionReasoningScore

Conciseness

The body is two lines with zero padding or explanation of concepts Claude already knows; nothing present is unnecessary, matching the 'lean and efficient' anchor.

5 / 5

Actionability

The only instruction is 'Do the thing.', which is entirely vague — it describes rather than instructs, with no concrete code, commands, or specific steps.

1 / 5

Workflow Clarity

No steps or sequence are given, and the single action is maximally ambiguous, so the simple-skill exception (which requires an unambiguous single action) does not apply.

1 / 5

Progressive Disclosure

The skill is under 50 lines, needs no external references (none exist in the bundle), and the minimal content is trivially well-organized under a single matching header, satisfying the rubric's simple-skill provision.

Description

0%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 fails on every dimension: it states no concrete capabilities, includes no trigger terms, answers neither 'what' nor 'when', and is indistinguishable from any generic placeholder. It reads as a scaffold rather than a usable skill description.

Suggestions

State 2-3 concrete actions the skill performs (e.g., what 'the thing' actually is), such as 'Validates X and generates Y'.

Add an explicit trigger clause, e.g., 'Use when the user mentions ...' with natural keywords and synonyms users would actually say.

Name a specific niche or domain so the skill cannot be confused with unrelated ones.

DimensionReasoningScore

Specificity

The description 'A minimal skill for testing' contains no concrete actions whatsoever, only abstract language; it is even thinner than the anchor-2 example 'Processes PDF files', which at least names a domain with a generic action.

1 / 5

Completeness

Neither a clear 'what' (no capabilities described) nor a 'when' (no 'Use when...' clause or equivalent trigger guidance) is present; both are extremely vague, matching the lowest anchor.

1 / 5

Trigger Term Quality

There are no natural keywords or phrases a user would say when needing this skill; 'minimal skill for testing' provides no domain terms, synonyms, or file extensions to trigger on.

1 / 5

Distinctiveness Conflict Risk

'A minimal skill for testing' is entirely generic and names no concrete domain or niche, so it would conflict with virtually any other skill at trigger time.
