Quality

Content

40%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 token-efficient and appropriately small for a test skill, but its sole instruction ('Do the nested thing.') is too vague to be actionable or to define a clear workflow. Structure is minimal but adequate given the tiny scope and absence of bundle files.

Suggestions

Replace 'Do the nested thing.' with a concrete, executable instruction or code example.

If the skill genuinely has multiple sub-steps, enumerate them explicitly with clear verbs.

Clarify what 'the nested thing' refers to so the single action is unambiguous.

DimensionReasoningScore

Conciseness

The body is maximally brief with no padding or over-explanation of concepts Claude already knows; it is efficient, though the lone instruction is too vague to be fully clear, keeping it just below a 5.

4 / 5

Actionability

'Do the nested thing.' is entirely abstract with no concrete code, commands, or specific steps, matching the 'Entirely vague or abstract; only describes rather than instructs' anchor.

1 / 5

Workflow Clarity

A single numbered step exists but it is poorly defined and ambiguous ('the nested thing'), fitting 'Rough sequence present but many gaps; steps poorly defined.'

2 / 5

Progressive Disclosure

The skill is under 50 lines with no bundle files and no need for external references, and the single heading plus one step is reasonably organized for its size, with only minor organization gaps keeping it below 5.

Description

17%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 reads as an internal test/scaffolding label rather than a capability description: it states the skill's role in testing recursive discovery but provides no concrete actions, no natural trigger terms, and no usage guidance. It would not help a user or Claude decide when to invoke it.

Suggestions

Rewrite the description to state concrete capabilities in third person (e.g., 'Performs X and Y on Z').

Add an explicit 'Use when...' clause with natural keywords a user would actually say.

Replace internal jargon ('packages/x/skills', 'recursive discovery') with user-facing trigger terms.

DimensionReasoningScore

Specificity

The phrase 'Nested skill under packages/x/skills, used to test recursive discovery' names a domain (recursive discovery testing) but offers no concrete user-facing actions, matching the anchor 'Names the domain but actions are minimal or generic.'

2 / 5

Completeness

It gives only a vague meta 'what' (a test artifact) and entirely lacks a 'when to use' trigger clause, fitting the 'vague what and no when' anchor.

2 / 5

Trigger Term Quality

It relies on internal/technical jargon ('recursive discovery', 'packages/x/skills') that no user would naturally say when needing this skill, matching the 'No natural keywords; only technical jargon' anchor.

1 / 5

Distinctiveness Conflict Risk

As a functional capability description it is very broad and generic with high overlap risk, since 'nested skill... used to test recursive discovery' does not carve out a distinguishable user-facing niche.
