chart-rendering

Visualise the result of an analysis as a chart (line, bar, area, scatter, etc.). Use when the user asks to "plot...", "chart...", "show me the trend of...", "visualise...", or when a numerical result has more than ~10 rows and would be easier to read as a picture. Produces an image file plus the script that generated it.

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.

A concise, well-structured rendering SOP with concrete conventions and clear sequencing. Its main gap is the absence of a complete executable script template and an explicit render-verification checkpoint.

Suggestions

Include a minimal copy-paste matplotlib script template under step 3 so the skill is fully executable out of the box.

Add an explicit verification checkpoint (e.g., confirm the PNG was written and re-run the script on tweak requests) to strengthen the workflow feedback loop.

Dimension	Reasoning	Score
Conciseness	Lean SOP with a decision table and tight conventions; assumes Claude knows matplotlib/pandas and avoids any padding or elementary explanation.	5 / 5
Actionability	Concrete paths, pandas verbs, and matplotlib params (bbox_inches='tight', dpi=150) are specified, but no complete copy-paste starter script template is provided.	4 / 5
Workflow Clarity	Five clearly sequenced steps with a soft caveat checkpoint in the interpretation step, but no explicit render-verification or error-recovery feedback loop.	4 / 5
Progressive Disclosure	Well-organized sections with one-level-deep cross-references ([[sql-analysis]], report-writer sub-agent), no nesting, and a self-contained body that is easy to navigate.	5 / 5

Description

87%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.

A strong, well-scoped description that clearly answers what the skill does and when to trigger it, with natural user phrasing and minimal overlap risk. It could be tightened only by adding a couple of chart synonyms.

Suggestions

Add synonyms like 'graph' or 'draw' to the trigger list for broader natural-language coverage.

Consider mentioning supported output formats explicitly (e.g., PNG) to round out the capability list.

Dimension	Reasoning	Score
Specificity	Names the domain and several concrete actions ('Visualise the result of an analysis as a chart (line, bar, area, scatter, etc.)', 'Produces an image file plus the script that generated it'), with only minor coverage gaps.	4 / 5
Completeness	Explicitly states both what it does (visualise analysis results as a chart, emit image + script) and when to use it with concrete trigger phrases, matching the top anchor.	5 / 5
Trigger Term Quality	Strong natural trigger phrases ('plot...', 'chart...', 'show me the trend of...', 'visualise...') plus a >10-row heuristic, but missing common synonyms such as 'graph' or 'draw'.	4 / 5
Distinctiveness Conflict Risk	A clear chart-rendering niche with specific triggers and explicit delegation of dashboards to the report-writer sub-agent, giving minimal conflict risk.	5 / 5
