Quality

Content

61%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 a clean, well-structured router/overview with efficient tables, but it delegates nearly all executable guidance to referenced files and lacks validation checkpoints in its workflow example.

Suggestions

Add explicit validation/verification steps to the usage example workflow (e.g., confirm the scaffolded project builds before coordinating agents).

Include at least one concrete command or minimal code snippet in the body so it is actionable without the referenced files.

Ensure the referenced files (project-detection.md, tech-stack.md, templates/*) are actually bundled so the progressive-disclosure pointers resolve.

DimensionReasoningScore

Conciseness

Mostly lean table-based overview that assumes Claude's competence; only minor redundancy such as restating the selective-reading rule.

4 / 5

Actionability

Provides routing structure and an illustrative process example, but the executable guidance lives entirely in referenced files with no commands or code in the body itself.

3 / 5

Workflow Clarity

The usage example lists a clear 6-step sequence but validation checkpoints are absent, matching the anchor with sequence present but checkpoints missing.

3 / 5

Progressive Disclosure

Well-signaled one-level-deep references via a content map and template table give good navigation, though no bundle files are present to verify the referenced paths exist.

Description

58%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 conveys concrete capabilities and a clear niche, but lacks an explicit 'Use when...' trigger clause and natural user-facing trigger phrases, which caps completeness and trigger-term quality.

Suggestions

Add an explicit 'Use when...' clause naming natural user triggers (e.g., 'Use when the user asks to build, scaffold, or generate an app from a description').

Include common user synonyms like 'web app', 'mobile app', or 'build an application' to improve trigger-term coverage.

Mention scaffolding/deployment as concrete actions to push specificity toward comprehensive coverage.

DimensionReasoningScore

Specificity

Lists several concrete actions ('Determines project type, selects tech stack, coordinates agents') with minor coverage gaps (no mention of scaffolding or deployment).

4 / 5

Completeness

A clear 'what' is present but there is no 'Use when...' trigger clause, capping completeness at 3 per the rubric guideline.

3 / 5

Trigger Term Quality

Has 'natural language requests' and 'full-stack applications' but misses common user phrases like 'build an app', 'web app', or 'mobile app'.

3 / 5

Distinctiveness Conflict Risk

'Main application building orchestrator' names a fairly distinct niche with only minor overlap risk against other app-building skills.
