The SDK harness is the only path now; legacy host-side code is gone.
File names no longer carry the ``sdk_`` distinction.
Deleted legacy host-side modules:
- strix/agents/StrixAgent/ (template moved to strix/agents/prompts/)
- strix/agents/base_agent.py, state.py
- strix/llm/llm.py, config.py
- strix/runtime/docker_runtime.py, runtime.py
- strix/tools/executor.py, agents_graph/agents_graph_actions.py
- strix/interface/sdk_dispatch.py + the env-flag dispatch in cli.py
Renamed (drop ``sdk_`` prefix):
- strix/sdk_entry.py → strix/entry.py
- strix/agents/sdk_factory.py → strix/agents/factory.py
- strix/agents/sdk_prompt.py → strix/agents/prompt.py
- strix/tools/<x>/<x>_sdk_tool[s].py → strix/tools/<x>/tool[s].py
- strix/tools/_legacy_adapter.py → strix/tools/_state_adapter.py
- ``_legacy`` aliases inside the wrappers → ``_impl``
CLI + TUI now call ``run_strix_scan`` directly — they build the
sandbox image / sources_path locally and rely on
``session_manager.cleanup`` (called inside ``run_strix_scan``'s finally)
for teardown. Three TUI handlers that reached into legacy multi-agent
globals (``_agent_instances``, ``send_user_message_to_agent``,
``stop_agent``) are now no-ops with a TODO; reconnecting them to the
``AgentMessageBus`` is a follow-up.
Tracer.get_total_llm_stats no longer reaches into the deleted
``agents_graph_actions`` globals — the orchestration hooks now feed the
tracer via ``Tracer.record_llm_usage`` (live + completed buckets).
finish_scan's ``_check_active_agents`` and load_skill's runtime
``_agent_instances`` reach-in are no-op stubs; the
``AgentMessageBus`` is the source of truth post-migration.
llm/utils.py rewritten to keep only the streaming-parser helpers
(``normalize_tool_format``, ``parse_tool_invocations``,
``fix_incomplete_tool_call``, ``format_tool_call``, ``clean_content``).
``STRIX_MODEL_MAP`` moved to ``llm/multi_provider_setup.py`` (its only
remaining caller).
Per-file ruff ignores added for legacy interface modules (TUI / main /
CLI / utils / streaming_parser / tool_components) and tracer.py —
pre-existing PLC0415/BLE001/PLR0915 patterns are out of scope.
Tests: 287/287 passing. Renamed test files to drop ``sdk_`` prefix.
``test_tracer.py::test_get_total_llm_stats_aggregates_live_and_completed``
rewritten to feed ``Tracer.record_llm_usage`` instead of legacy globals.
Test file annotations added so pre-commit's strict mypy passes.
Phase 2.1 — sandbox dispatch helper:
- strix/tools/_sandbox_dispatch.py: post_to_sandbox() centralizes the
host->container HTTP wire format. Connect=10s, read=150s timeouts mirror
legacy executor.py. 50 MB response cap (C18) prevents OOM from a runaway
tool. All errors surface as {"error": str} so the model can recover
instead of the run dying.
Phase 2.2 — C6 lock-protected JSONL writes:
- strix/tools/notes/notes_actions.py: notes.jsonl appends are now wrapped
in _notes_lock so concurrent agents can't interleave half-written lines.
Regression test in test_notes_jsonl_concurrency.py verifies 1000 parallel
writes produce exactly 1000 valid JSON lines.
Phase 2.3 — thin-slice SDK wrappers (think + todo + notes):
- strix/tools/_legacy_adapter.py: LegacyAgentStateAdapter shim — exposes
just enough surface (.agent_id) for legacy tools that close over
agent_state, sourced from ctx.context['agent_id'].
- strix/tools/thinking/thinking_sdk_tools.py: 1 tool (think).
- strix/tools/todo/todo_sdk_tools.py: 6 tools (create/list/update/done/
pending/delete) with bulk-form preserved.
- strix/tools/notes/notes_sdk_tools.py: 5 tools (create/list/get/update/
delete) with asyncio.to_thread around the lock-protected file I/O.
Tests: 22 new tests pass (10 sandbox dispatch + 2 concurrency + 10 SDK
local). Full suite still green.
Per-file ruff ignores added for SDK wrapper files: TC002 (RunContextWrapper
must be runtime-importable because the SDK calls get_type_hints() to
derive the JSON schema) and PLR0911 (sandbox dispatch's 10 short-circuit
returns are intentional, each a distinct documented failure mode).
