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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.00419 |
| Opus 5.5 | $0.00011 | $0.00168 |
| Sonnet 5.5 | $0.00005 | $0.00084 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
chart-image 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
Rylai Codex-Hermes-Claude Edition | Original portable workflow by Rylai
Runtime Compatibility
- Codex: install under
~/.agents/skills/chart-image. - Hermes: install under
~/.hermes/skills/chart-imageor expose the bundle throughskills.external_dirs. - Claude Code: install under
~/.claude/skills/chart-imageor<project>/.claude/skills/chart-image. - Claude.ai and Cowork: upload and enable the matching per-skill ZIP.
- Resolve bundled files relative to this skill directory; do not depend on paths from another machine.
- Check tools, packages, credentials, network access, and runtime capabilities before execution.
Portable Chart Image
Generate a chart image from the actual supplied data.
Workflow
- Inspect the schema, units, missing values, categories, and time fields.
- Choose a chart type that matches the analytical question.
- Use an available library such as Matplotlib, Seaborn, Plotly, Vega-Lite, or the repository's existing chart stack.
- Label axes, units, legends, source, and uncertainty where relevant.
- Prefer
node scripts/chart.mjsfor portable SVG output, or use the repository's installed plotting stack. - Inspect the rendered image for clipping, unreadable labels, misleading scales, and color contrast.
Integrity
- Do not infer values that are absent from the data.
- Start quantitative axes at an appropriate baseline and disclose truncation.
- Preserve a reproducible script or notebook with the output.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-image is a skill published in the GitHub repository Rylaispirit/rylai-codex-hermes-skills (63 stars, last pushed 2mo ago), licensed MIT. It adds 27 tokens to every session and 419 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 2026-08-30.
