Quality

Content

87%

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

The body is concise, concrete, and well-structured with executable examples and clear behavioral guidance. The main gap is the absence of a validation/recovery checkpoint in the build workflow, which the rubric caps at 2 given SQLite data operations.

DimensionReasoningScore

Conciseness

The body is lean — short bullets, copy-paste snippets, and behavioral guidance — with no explanation of concepts Claude already knows; every section earns its place.

3 / 3

Actionability

It gives fully executable, copy-paste-ready guidance such as `int(os.environ.get('PORT', '8000'))` and `from flask import Flask, render_template, request, jsonify`, plus a concrete file layout and framework-selection rules.

3 / 3

Workflow Clarity

The numbered 1–4 workflow provides a clear sequence, but there are no validation/feedback checkpoints, and because persistence uses SQLite the rubric caps workflow_clarity at 2.

2 / 3

Progressive Disclosure

At under 50 lines with no bundle files and no need for external references, the well-organized sections (framework choice, constraints, layout, workflow, don'ts) satisfy the simple-skills allowance for a top score.

Description

57%

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 names a concrete niche (on-device Python web apps with Flask/Django/stdlib) but lacks an explicit "Use when…" trigger and leans on a single action verb. Adding trigger phrasing and natural keyword variations would lift the weakest dimensions.

Suggestions

Append a "Use when the user wants a Python backend, API, or web server on-device" clause to supply explicit trigger guidance (raises completeness).

Add natural variations users say — "Python backend", "API endpoint", "web server" — and drop or soften the jargon "on-device Python runtime" (raises trigger_term_quality).

List a second concrete action (e.g. "add endpoints", "wire SQLite persistence") so the description shows multiple specific actions rather than just "Build" (raises specificity).

DimensionReasoningScore

Specificity

"Build a Python web app (Flask, Django, or stdlib)" names the domain and three concrete framework options, but it offers a single action verb rather than multiple distinct concrete actions as the anchor-3 example does.

2 / 3

Completeness

It states what the skill does but contains no "Use when…" clause or equivalent explicit trigger guidance, which per the rubric caps completeness at 2.

2 / 3

Trigger Term Quality

"Python web app", "Flask", and "Django" are natural user terms, but "on the on-device Python runtime" is technical jargon and common variations like "Python backend", "API", or "web server" are missing.

2 / 3

Distinctiveness Conflict Risk

"on the on-device Python runtime" carves out a clear niche bounded by a specific runtime, making it unlikely to trigger for unrelated web-app or code skills.
