errors.py DOX

Purpose

• Own the errors.py helper module.
• This module defines framework exceptions and safe error formatting.
• Keep this file-level DOX profile synchronized with errors.py because this directory is intentionally flat.

Ownership

• errors.py owns the runtime implementation.
• errors.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• RepairableException (Exception)
• InterventionException (Exception)
• HandledException (Exception)
• Top-level functions:
• handle_error(e: Exception)
• error_text(e: Exception)
• format_error(e: Exception, start_entries=..., end_entries=..., error_message_position: Literal['top', 'bottom', 'none']=...)

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.
• Imported dependency areas include: asyncio, re, traceback, typing.

Key Concepts

• Important called helpers/classes observed in the source: join, traceback_text.split, traceback.format_exception, re.match, type, line.strip.startswith, trimmed_lines.strip, error_message.strip, line.strip.
• 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/test_browser_agent_regressions.py
  • tests/test_fasta2a_client.py
  • tests/test_host_browser_connector.py
  • tests/test_office_desktop_state.py
  • tests/test_office_document_store.py
  • tests/test_skills_runtime.py
  • tests/test_speech_plugin_split.py
  • tests/test_time_travel.py
