messages.py DOX

Purpose

• Own the messages.py helper module.
• This module truncates message payloads for display and storage safety.
• Keep this file-level DOX profile synchronized with messages.py because this directory is intentionally flat.

Ownership

• messages.py owns the runtime implementation.
• messages.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Top-level functions:
• truncate_text(agent, output, threshold=...)
• truncate_dict_by_ratio(agent, data: dict | list | str, threshold_chars: int, truncate_to: int)

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 writes, settings/state persistence.
• Imported dependency areas include: json.

Key Concepts

• Important called helpers/classes observed in the source: agent.read_prompt, process_item, json.dumps, truncate_text.
• 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.
• Related tests observed by source search:
  • tests/email_parser_test.py
  • tests/test_browser_agent_regressions.py
  • tests/test_chat_compaction.py
  • tests/test_document_query_fallback.py
  • tests/test_download_toast_regressions.py
  • tests/test_fasta2a_client.py
  • tests/test_mcp_handler_multimodal.py
  • tests/test_oauth_codex.py
