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 | $0.00224 | $0.05131 |
| Opus 5.5 | $0.00090 | $0.02052 |
| Sonnet 5.5 | $0.00045 | $0.01026 |
| Haiku 4.5 | $0.00022 | $0.00513 |
Grade A, and why
devexpress-wpf-charts 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 409 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevExpress WPF Chart Control
DevExpress.Xpf.Charts.ChartControl is the 2D charting control for WPF applications. A chart is composed of a Diagram (which determines the coordinate system — Cartesian, polar, radar, simple), one or more Series (the actual data plots: bar, line, area, pie, financial, etc.), Axes for Cartesian-like diagrams, plus optional Title, Legend, Annotations, Tooltip, and Crosshair Cursor. Series bind to data through DataSource + ArgumentDataMember / ValueDataMember, with automatic scale-type detection and built-in aggregation.
3D charting uses a separate control (
Chart3DControl) and is rarely needed. This skill coversChartControl(2D).
When to Use This Skill
Use this skill when you need to:
- Add a chart to a WPF window
- Bind a chart to an
IEnumerable/ObservableCollection/DataTable - Pick a series type (bar, line, area, pie, financial, point, bubble, polar, radar, funnel, box plot)
- Configure primary or secondary axes
- Pick an axis scale type (Numerical, DateTime, TimeSpan, Qualitative)
- Add axis titles, custom labels, format label text via patterns
- Aggregate data for performance or readability
- Add a legend, format legend items, enable check boxes for series visibility
- Show tooltips and the crosshair cursor; format their content
- Enable end-user selection (Single, Multiple, or Extended)

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.

devexpress-wpf-charts is a skill published in the GitHub repository DevExpress/agent-skills (66 stars, last pushed 4d ago), licensed MIT. It adds 224 tokens to every session and 5,131 once invoked, about $0.0009 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 2026-10-20.
