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 | $0.00676 | $0.00676 |
| Opus 5.5 | $0.00270 | $0.00270 |
| Sonnet 5.5 | $0.00135 | $0.00135 |
| Haiku 4.5 | $0.00068 | $0.00068 |
Grade A, and why
chart-visualization-skills AGENTS.md 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.
How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file defines the maintenance principles and constraints for agents modifying this repository. It is not a project introduction or a setup guide.
Principles
skills/is the single source of truth for chart generation knowledge. All changes to chart usage, best practices, and constraints belong in skill documents, not scattered across code or other docs.- Keep it simple. Prefer editing existing files; do not add new files or abstraction layers unless necessary.
- Keep code and docs in sync. When changing skill content or retrieval logic, update the affected indexes, tests, and docs in the same change.
- Write for retrieval quality. Skill frontmatter fields (
title,description,tags,use_cases,anti_patterns) are retrieval fields — write them so the skill can be found accurately, not just read by humans.
Constraints
- After modifying skill documents under
src/content/, rebuild the index (npm run build:index) and run tests (npm test). - Do not introduce new runtime dependencies unless strictly necessary; prefer existing dependencies (
@antv/context,commander,gray-matter). - Do not change the zvec index field structure or embedding dimension (512d) unless the build script, retriever, and all tests are updated accordingly.
- Write commit messages in English.
Keeping Docs and Config in Sync
Whenever a skill is added, modified, or removed under skills/, keep the following in sync in the same change:
1. README.md — "Available Skills" section
- Every skill directory under
skills/must be listed under## Available Skills. - Each entry must include an emoji icon, the skill name in bold (matching the directory name), a one-line description matching the skill's
SKILL.mdfrontmatterdescription, and a short paragraph elaborating on its capabilities. - Add entries for new skills, update entries for changed skills, and remove entries for deleted skills. Preserve the section's existing formatting style.
2. .claude-plugin/marketplace.json — plugins array
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.
