Quality

Content

75%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 exceptionally lean and well-sectioned, with a sequenced workflow that includes real validation checkpoints. Its main weakness is actionability: tool and CLI names are given without any executable example, and key inputs are deferred to documentation that is neither linked nor included in the bundle.

Suggestions

Show one concrete invocation of the runtime/aas-core.cjs CLI (or link the file documenting the preview inputs) so the filesystem-planning step is executable from the skill alone.

Replace the meta-instruction Examples section with a concrete example: a sample user request and the expected manifest/evidence output shape.

Restructure the dense multi-action Workflow paragraphs into a short numbered sequence so the step order and validation checkpoints are explicit.

DimensionReasoningScore

Conciseness

The ~28-line body contains zero padding: every sentence is direct instruction or domain-specific caution (e.g. "The project ledger is an agent declaration and its checks do not prove semantic coverage"), with no explanation of concepts Claude already knows. Not 4 because no instance of over-explanation can be identified to trim.

5 / 5

Actionability

Exact tool names are given ("Call compose_stack", "Call inspect_stack", "use the bundled runtime/aas-core.cjs offline CLI") but no executable example, command line, or parameter shape appears anywhere; usage is deferred to "the documented preview inputs", which are neither linked nor bundled. Not 4 because the missing operational details (CLI invocation, preview input shape) are key details rather than minor gaps, and not 2 because tool names and their key parameters are concrete.

3 / 5

Workflow Clarity

A clear ordered sequence (inspect project → enumerate capabilities → search catalog → compose_stack → inspect_stack → optional evidence calls) is present with genuine checkpoints: "Resolve an ambiguous target with the user", "report error results without treating them as success", and "restart discovery and composition rather than inventing a trace". Not 5 because the sequence is embedded in dense prose rather than explicit numbered steps and there is no structured error-recovery loop; not 3 because the checkpoints are explicitly stated, not implicit.

4 / 5

Progressive Disclosure

The body is well organized into appropriately sized sections (When to Use, Workflow, Examples, Limitations) with no content that should be split out, fitting the good-structure anchor. Not 5 because references to bundled material ("runtime/aas-core.cjs", "the documented preview inputs") are not clearly signaled with paths, and no bundle file is present to navigate to; not 3 because the structure itself is good rather than merely adequate.

Description

53%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 states one specific, domain-relevant action but provides no trigger guidance and few natural keywords. It is distinguishable from unrelated skills mainly through its niche jargon rather than through explicit use-when phrasing.

Suggestions

Add an explicit trigger clause, e.g. "Use when the user explicitly asks to compose, validate, or preserve an AAS skill stack or export selection evidence."

Include natural keywords and synonyms users would actually say (e.g. "AAS stack", "compose a skill stack", "skill selection evidence") rather than only technical phrasings.

Enumerate the concrete actions performed (inspect the project, search the catalog, compose the stack, inspect the manifest, export evidence) instead of summarizing them into a single jargon-heavy clause.

DimensionReasoningScore

Specificity

Names the domain ("AAS skill selection") and one concrete action ("Preserve... as a validated stack and optional evidence"), matching the 1-2-concrete-actions anchor. It is not 4 because only a single action verb is listed rather than several specific actions, and not 2 because the action stated is specific rather than generic.

3 / 5

Completeness

It clearly states what the skill does ("Preserve the coding agent's explicit AAS skill selection as a validated stack and optional evidence") but has no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Not 4 because the 'when' is entirely missing rather than merely imprecise.

3 / 5

Trigger Term Quality

Keywords like "AAS skill selection", "validated stack", and "evidence" are relevant to the domain but are technical phrasings; natural trigger terms a user would say and their common variations are missing. Not 4 because natural user phrasings are absent, and not 2 because the terms are domain-relevant rather than generic.

3 / 5

Distinctiveness Conflict Risk

The niche (AAS stack composition/preservation) is highly specific, so overlap with unrelated skills is unlikely, but terms like "AAS", "skill", and "stack" overlap with other AAS-family skills and no distinct trigger phrase is provided. Not 5 because the anchor requires distinct triggers, which the description lacks.
