v0.1.2 — Agent Skills support

v0.1.2 — Agent Skills support (.agents/skills standard)

Ship one skill that every major AI tool auto-discovers.

What's new

• Canonical Agent Skills file at .agents/skills/echarts/SKILL.md — the cross-tool standard location (agentskills.io) scanned by Claude Code, OpenCode, Codex, Antigravity, Cursor, and others.
• install-skills command — npx @ryuk3nd0/echarts-mcp install-skills copies the skill into each tool's personal discovery directory:
  • Claude Code: ~/.claude/skills/echarts/
  • OpenCode: ~/.config/opencode/skills/echarts/
  • Codex / Antigravity / Cursor: ~/.agents/skills/echarts/ (shared standard)
• Skill arrives inside the npm package (.agents/skills/ in the tarball) and is committed to the repo for project-level discovery.
• SKILL.md frontmatter fixed (name: echarts, proper 'use when' description) and documents the portable-option workflow: the returned option JSON can be dropped directly into a browser echarts.init(dom) build for live charts.

Research-backed

Cross-tool discovery conventions were verified against primary sources (code.claude.com, opencode.ai, developers.openai.com, antigravity.google, cursor.com, agentskills.io). Full reference: agent-skills-discovery-reference.md.

Verification

• 23 tests pass (5 suites), typecheck/lint/build clean.
• Skills auto-discovery proven live: the harness itself picked up .agents/skills/echarts/SKILL.md as a loadable echarts skill.

Note

• npm publish is 2FA-gated and handled by the maintainer manually, not automation.
• After npm i -g @ryuk3nd0/echarts-mcp, run echarts-mcp install-skills to install the skill into your tools.
