chart-visualization-skills: Skill for Claude Code

.github/skills/antv-skills-maintainer/SKILL.md

antv-skills-maintainer is a skill for Claude Code from antvis/chart-visualization-skills. It costs 45 tokens per session (770 once invoked), scanned A, original, MIT.

A maintenance skill for the AntV chart-visualization skills repository. It updates the README and plugin marketplace configuration when user-facing skills are added, changed, or removed.

In plain words
What is it for?
Keeping the available-skills list, descriptions, icons, and marketplace entries aligned with the repository's skill folders, while excluding internal-only skills.
Why use it?
It prevents documentation and configuration from falling out of sync with the skills that are actually available.

Skill for Claude Code

Written for Claude Code: Claude Code plugin machinery.

This is antvis/chart-visualization-skills's own configuration. It tells Claude Code how to work on chart-visualization-skills itself, so it is not a mod to install elsewhere.

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

antv-skills-maintainer 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 11d 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.

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AntV Skills Maintainer

This skill ensures that all documentation and configuration files remain in sync whenever a skill is added or updated in this repository.

Important

The antv-skills-maintainer skill is internal-only — it is used solely for this repository's iteration workflow. Do not add it to README.md "Available Skills" or .claude-plugin/marketplace.json. Only user-facing skills should appear in those files.

When to Apply

Apply this skill automatically after every code change — especially when:

  • A new skill directory is added under skills/
  • An existing skill's SKILL.md is modified (name, description, capabilities)
  • A skill is removed or deprecated

What to Keep in Sync

1. README.md — "Available Skills" Section

The ## Available Skills section in README.md must list every skill under skills/ with:

  • An appropriate emoji icon
  • The skill name (bold, matching the directory name)
  • A one-line description matching the skill's SKILL.md frontmatter description field
  • A short paragraph elaborating on the skill's capabilities

Format:

- 🔧 **skill-name**: One-line description from SKILL.md frontmatter.

`Skill Display Name` elaboration paragraph...

Steps:

  1. Scan skills/ directory to list all available skills.
  2. Read each skill's SKILL.md frontmatter (name, description).
  3. Compare with the current ## Available Skills section in README.md.
  4. Add entries for new skills, update entries for changed skills, remove entries for deleted skills.
  5. Preserve the section's existing formatting style.

2. .claude-plugin/marketplace.json — Plugins Array

The plugins array in .claude-plugin/marketplace.json must contain an entry for every skill under skills/.

Entry format:

{
  "name": "skill-name",
  "description": "Description from SKILL.md frontmatter.",
  "source": "./",
  "strict": false,
  "skills": [
    "./skills/skill-name"
  ]
}

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.
