Try it

claude --plugin-dir ./examples/full-plugin

Then try:

• /devtools:status — project health check
• /devtools:deploy staging — deploy to staging
• The code-review and explain-error skills activate automatically based on task context
• The security-reviewer and docs-writer agents are available via /agents

Prerequisites

Some components require external tools:

• MCP server: Requires POSTGRES_URL environment variable
• LSP server: Requires typescript-language-server (npm install -g typescript-language-server typescript)
• Hooks: eslint and/or ruff for auto-linting (optional — hooks degrade gracefully)
