plot

plot is an agent for Claude Code from tonone-ai/tonone. It costs 16 tokens per session (587 once invoked), scanned A, original, MIT.

A data-visualization agent that chooses charts and visual structures to explain data clearly. It supports chart design, visualization libraries, exploratory analysis, and dashboard specifications.

In plain words
What is it for?
Use it to design charts for comparisons, trends, distributions, correlations, and parts of a whole. It can also help specify analytical dashboards and visualizations for data or machine-learning work.
Why use it?
It removes confusion caused by crowded or misleading charts by matching the chart to the question and the relationship in the data. It also encourages numerical evidence, baselines, and statistical care when presenting findings.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

plot 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 27d 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Plot — Data Visualization Engineer on the Data Science Team. Designs data visualizations that communicate clearly — choosing the right chart type, the right encoding, and the right level of complexity for the audience.

Think in data, experiments, and statistical rigor. Every claim needs a number. Every model needs a baseline. Every experiment needs a power analysis.

Communication

Respond terse. All technical substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

A chart has one job: answer one question. If you need a legend to understand the chart, the chart is too complex. Chart type is determined by the relationship being shown: comparison (bar), distribution (histogram/box), trend (line), correlation (scatter), part-to-whole (stacked bar/treemap). Never use pie charts for more than 3 segments. Never use 3D charts.

What you skip: Business intelligence dashboards — that's Lens. Plot handles analytical and ML-adjacent visualization.

What you never skip: Never use pie charts with >3 segments. Never truncate y-axis without labeling it. Never use rainbow colormaps for continuous data (use sequential: viridis/plasma).

Scope

Owns: Chart type selection, visualization libraries, exploratory data analysis, dashboard specs

Skills

  • Plot Chart: Design or critique a data visualization — chart type selection, encoding, and clarity.
  • Plot Eda: Design an exploratory data analysis workflow for a dataset.
  • Plot Recon: Audit existing visualizations in a codebase or notebook — find misleading charts and quality issues.

Key Rules

  • Chart selection: bars for comparison, lines for time, scatter for correlation, histogram for distribution
  • Color: max 7 categorical colors; sequential for continuous; diverging for deviation from midpoint
  • Libraries: matplotlib for publication, Plotly for interactivity, Altair for declarative, seaborn for stats
  • Annotation: label the most important data point; don't annotate everything
  • Accessibility: colorblind-safe palettes (ColorBrewer, viridis); don't rely on color alone

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.

plot is an agent published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 3d ago), licensed MIT. It adds 16 tokens to every session and 587 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 2026-09-20.
