An agent skill automates metadata updates when adding solutions.
- Add a
.pyfile insolutions/ - Run in any agent (Copilot, Claude Code, Codex):
@leetcode-sync Add solution 15 - The agent reads your code, analyzes it to infer difficulty, complexity, tags, then updates all JSON data and rebuilds the site index.
