message.py DOX

Purpose

• Own the message.py API endpoint.
• This module submits a user message and runs agent processing synchronously through the UI API.
• Keep this file-level DOX profile synchronized with message.py because this directory is intentionally flat.

Ownership

• message.py owns the runtime implementation.
• message.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• Message (ApiHandler)
  • async process(self, input: dict, request: Request) -> dict | Response
  • async respond(self, task: DeferredTask, context: AgentContext)
  • async communicate(self, input: dict, request: Request)

Runtime Contracts

• HTTP handlers must derive from helpers.api.ApiHandler; WebSocket handlers must derive from helpers.ws.WsHandler.
• Update this file whenever request payloads, authentication or CSRF requirements, response shapes, route side effects, or WebSocket event contracts change.
• Message is an ApiHandler.
• Message defines process(...).
• Observed side-effect areas: filesystem reads, filesystem writes, settings/state persistence, scheduler state.
• Imported dependency areas include: agent, helpers, helpers.api, helpers.defer, helpers.security, os.

Key Concepts

• Important called helpers/classes observed in the source: request.content_type.startswith, self.use_context, mq.log_user_message, self.communicate, self.respond, task.result, request.files.getlist, files.get_abs_path, request.get_json, extension.call_extensions_async, context.communicate, os.makedirs, UserMessage, safe_filename, attachment.save, context.get_agent, os.path.join.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve authentication, CSRF, loopback, and API-key checks unless the endpoint contract explicitly changes.
• Update frontend callers, plugin callers, and tests together when payload shape changes.
• Use helpers.api.Response for non-JSON responses, files, redirects, or status-specific replies.

Verification

• Run endpoint-specific or API/WebSocket tests for changed behavior; smoke-test browser callers when no focused test exists.
• Related tests observed by source search:
  • tests/email_parser_test.py
  • tests/rate_limiter_test.py
  • tests/test_api_chat_lifetime.py
  • tests/test_browser_agent_regressions.py
  • tests/test_chat_compaction.py
  • tests/test_docker_release_plan.py
  • tests/test_document_query_fallback.py
  • tests/test_download_toast_regressions.py
