Chinese Calendar with Lunar-Solar Conversion
Browser automation via Chrome/Chromium CDP — open, snapshot, click, screenshot. For testing web apps, mobile layouts, and automated interactions without Playwright/Puppeteer.
Lovable MCP tool usage — deploy projects, message agent, test with agent-browser. Minimize credits by delegating to local repo.
Typed knowledge graph via TSV append-only log — entity CRUD, directed relations, schema validation, multi-hop reasoning. CLI via `x ondb`, protocol readable by AWK/Python/JS/SQLite.
Prompt engineering conventions for x-cmd — reuse via template variables, structure rules, safety enforcement patterns.
Root index of x-cmd skill0 sub-skills. Defines the OKR-style agent workflow (goal → rule-verified results → execute), skill discovery, and agent tooling preferences. Style: principle-first, concise, delegate specifics to authoritative external sources.
Writing conventions for skill0 documents — pyramid structure, line limits, and layout rules.
