guides on formatting and linting code inside automation platforms. each one covers why standard formatters fail on a platform's wrapped runtime, and how to get clean, working code back.

## for agents (added to every page twin, not part of the page)

- format API: POST https://codefmt.dev/api/format (OpenAPI: https://codefmt.dev/api/openapi.json, code up to 51,200 characters, 50KB of ASCII (400 above it), request body up to 100KB, counted in bytes (413 above it), no authentication)
- MCP server: POST https://codefmt.dev/api/mcp (tools: format_code, format_json, ask_codefmt; manifest: https://codefmt.dev/.well-known/mcp.json)
- rate limit: 60 requests per minute per ip across format api calls, mcp and a2a tool calls, and /ask (mcp handshakes and listings are not counted). the count is kept per server instance, so treat it as a ceiling to stay under rather than an exact budget. the format api reports where you stand in RateLimit headers and its 429 carries Retry-After; /ask answers a 429 with the message in answer, and an mcp tool call over the limit returns a tool result saying to try again in a minute
- auth statement: https://codefmt.dev/auth.md (no accounts, api keys or oauth; send no authorization header)
- site index for agents: https://codefmt.dev/llms.txt
- full reference (request bodies for every language, a copy-paste curl command, platform globals, troubleshooting): https://codefmt.dev/llms-full.txt
