Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.00332 |
| Opus 5.5 | $0.00008 | $0.00133 |
| Sonnet 5.5 | $0.00004 | $0.00066 |
| Haiku 4.5 | $0.00002 | $0.00033 |
Grade A, and why
chart-selection scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Chart Selection
Choosing the Right Chart
| Data Relationship | Best Chart |
|---|---|
| Change over time | Line chart, area chart |
| Comparison | Bar chart (horizontal for many categories) |
| Part of whole | Pie/donut (max 5 slices), stacked bar |
| Distribution | Histogram, box plot |
| Correlation | Scatter plot |
| Geographic | Map (choropleth, point map) |
| Flow/process | Sankey diagram, funnel |
| Hierarchy | Treemap, sunburst |
Chart Anatomy
- Title: States the insight, not the data ('Revenue grew 40% in Q3' not 'Revenue Q1-Q4')
- Axes: Labeled with units, starting at zero for bars (not for lines)
- Legend: Only when multiple series, positioned near the data
- Gridlines: Minimal, light gray, horizontal only
- Annotations: Call out key points directly on the chart
Common Mistakes
- Pie charts with more than 5 slices (unreadable)
- 3D charts (distort perception)
- Dual Y-axes (confusing, usually misleading)
- Truncated Y-axis on bar charts (exaggerates differences)
- Too many colors (use one hue with variations for most charts)
- Missing context (what's the benchmark? trend? target?)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

chart-selection is a skill published in the GitHub repository Dragoon0x/everything-design-taste (13 stars, last pushed 6mo ago), licensed MIT. It adds 20 tokens to every session and 332 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
