context_utils.py DOX

Purpose

Own the context_utils.py helper module.
This module provides context managers/utilities for current context binding.
Keep this file-level DOX profile synchronized with context_utils.py because this directory is intentionally flat.

context_utils.py owns the runtime implementation.
context_utils.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
Top-level functions:
use_context(lock: ThreadLockType, ctxid: str, create_if_not_exists: bool=...)

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: WebSocket state, settings/state persistence.
Imported dependency areas include: threading, typing.

Newly constructed contexts reconcile their active profile against Global availability before returning. Existing context lookups return the stored context unchanged; explicit profile and project transitions own any repair.
Important called helpers/classes observed in the source: AgentContext.use, AgentContext.first, AgentContext, Exception, initialize_agent, projects.get_context_project_name, projects.reconcile_agent_profile.
Keep request/response, tool, or helper semantics documented here at the same time as source changes.

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.

Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
tests/test_projects.py verifies that lookup is read-only while context creation reconciles once.

No child DOX files.
