Quality

Content

86%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 lean, well-structured, and actionable with concrete tool calls and a clear sequenced workflow. The main gap is a missing validation/feedback loop for the outward-facing GCS publish step.

Suggestions

Add an explicit validation step after publishing (e.g., verify the returned https URL is publicly accessible / image loads before embedding it in the HTML).

Fully specify tool signatures and return values so the guidance is copy-paste ready, raising actionability to 5.

Add a brief error-recovery path for when publish_file fails or the URL is unreachable.

DimensionReasoningScore

Conciseness

The ~22-line body is lean and procedural, assuming Claude's competence without explaining what HTML or GCS is; every line earns its place.

5 / 5

Actionability

Provides concrete tool calls with signatures (publish_file(content, filename, 'image/png'), render_html, load_artifacts) and a real HTML snippet, but the calls are internal/agent-tool names with partial signatures rather than fully copy-paste-ready code.

4 / 5

Workflow Clarity

A clear 6-step numbered sequence with an explicit ordering checkpoint ('MUST publish the image bytes FIRST'), but no validate-then-retry feedback loop confirming the public URL is accessible before embedding—an outward-facing publish failure mode.

4 / 5

Progressive Disclosure

Under 50 lines with no external bundle files needed; content is organized into clear sections (Objective, Execution Steps, Final Delivery Options), satisfying the simple-skill exception.

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 is concrete and reasonably specific but is missing an explicit 'Use when...' trigger clause, which caps its completeness. Adding natural user-facing trigger phrases would raise both completeness and trigger-term quality.

Suggestions

Add an explicit 'Use when...' clause with natural trigger phrases (e.g., 'Use when the user wants to publish or share a report, create charts from metrics, or upload results to Google Cloud Storage').

Include common synonyms and formats users mention ('bar chart', 'dashboard', 'shareable link', 'PNG') to broaden natural keyword coverage.

Optionally enumerate concrete chart/report types to strengthen specificity beyond 1-2 actions.

DimensionReasoningScore

Specificity

Names the visualization/reporting domain with several concrete actions (charts, published shareable HTML reports, Google Cloud Storage), placing it just above the 1-2 action anchor but short of comprehensive multi-action coverage.

4 / 5

Completeness

Clearly states the 'what' but has no 'Use when...' or equivalent trigger clause, which per guidelines caps completeness at 3 rather than 4.

3 / 5

Trigger Term Quality

Contains relevant domain keywords ('visual charts', 'HTML reports', 'Google Cloud Storage', 'metrics') but omits the natural phrasings a user would say ('make a chart', 'publish a report', 'share a dashboard'), keeping it at the some-keywords anchor.

3 / 5

Distinctiveness Conflict Risk

The GCS-publishing and HTML-report niche is mostly distinct from generic skills with only minor overlap risk against general charting/reporting skills.
