message_queue.py DOX

Purpose

• Own the message_queue.py helper module.
• This module stores and drains queued user messages for a context.
• Keep this file-level DOX profile synchronized with message_queue.py because this directory is intentionally flat.

Ownership

• message_queue.py owns the runtime implementation.
• message_queue.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Top-level functions:
• get_queue(context: 'AgentContext') -> list: Get current queue from context.data.
• _get_next_seq(context: 'AgentContext') -> int: Get next sequence number.
• _sync_output(context: 'AgentContext'): Sync queue to output_data for frontend polling.
• add(context: 'AgentContext', text: str, attachments: list[str] | None=..., item_id: str | None=...) -> dict: Add message to queue. Attachments should be filenames, will be converted to full paths.
• remove(context: 'AgentContext', item_id: str | None=...) -> int: Remove item(s). If item_id is None, clears all. Returns remaining count.
• pop_first(context: 'AgentContext') -> dict | None: Remove and return first item.
• pop_item(context: 'AgentContext', item_id: str) -> dict | None: Remove and return specific item.
• has_queue(context: 'AgentContext') -> bool: Check if queue has items.
• log_user_message(context: 'AgentContext', message: str, attachment_paths: list[str], message_id: str | None=..., source: str=...): Log user message to console and UI. Used by message API and queue processing.
• send_message(context: 'AgentContext', item: dict, source: str=...): Send a single queued message (log + communicate).
• send_next(context: 'AgentContext') -> bool: Send next queued message. Returns True if sent, False if queue empty.
• send_all_aggregated(context: 'AgentContext') -> int: Aggregate and send all queued messages as one. Returns count of items sent.
• Notable constants/configuration names: QUEUE_KEY, QUEUE_SEQ_KEY, UPLOAD_FOLDER.

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Observed side-effect areas: filesystem reads, filesystem deletion, settings/state persistence.
• Imported dependency areas include: helpers, helpers.print_style, os, typing, uuid.

Key Concepts

• Important called helpers/classes observed in the source: context.set_data, get_queue, context.set_output_data, _sync_output, queue.pop, context.log.log, log_user_message, context.communicate, pop_first, has_queue, join, context.get_data, att.startswith, _get_next_seq, uuid.uuid4, UserMessage, send_message, guids.generate_id, os.path.basename, PrintStyle.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• No direct test reference was found by name search; choose the nearest behavioral test or perform a focused smoke check.
