Main's load_skill tool was deleted during the SDK migration along
with the prompt-mutation pattern it relied on. Re-add the capability
without the mutation: load_skill(skills=[...]) now returns the skill
markdown bodies as a tool result, so the content lands in conversation
history as in-context reference rather than as patched-in system
prompt content. Same source of truth (load_skills + skill files),
same validation (validate_requested_skills) as create_agent.
Tool result format is plain markdown (## Skill: <name> headers joined
with ---), not the <specialized_knowledge> XML wrapping used at
agent-build time. The XML framing was deliberately reserved for
prompt-level privileged context; tool-loaded skills are honestly
labelled as just-fetched reference material.
Close the discovery loop by surfacing the full skill catalog in the
system prompt. Without it the model could only guess skill names —
discovering them via validation errors on misses. Now every agent
sees a categorised <available_skills> block right after the
<specialized_knowledge> block with a short hint pointing at
create_agent / load_skill.
Skills module: factored _iter_user_skill_files() so get_all_skill_names
(set, for validation) and get_available_skills (dict by category,
for the prompt) share one source of truth on what counts as
user-selectable. Internal categories (scan_modes, coordination) stay
excluded from both.

Critical fixes:
- ``StrixOrchestrationHooks.on_agent_start`` now finds the
``CaidoCapability`` via ``ctx.context['caido_capability']`` instead
of ``agent.capabilities`` (we use plain ``Agent``, not
``SandboxAgent``, so the latter never existed). The session
manager's bundle already exposes the capability; ``run_strix_scan``
threads it through ``make_agent_context`` and ``create_agent``
forwards it to children.
- ``run_strix_scan`` registers the ``StrixTracingProcessor`` with the
SDK's tracing provider via ``add_trace_processor`` so SDK trace
spans hit ``run_dir/events.jsonl`` (was previously a parallel stream
the SDK ignored).
- ``on_llm_end`` now writes to ``Tracer.record_llm_usage`` in
addition to ``bus.record_usage`` so the CLI/TUI stats panel sees
real numbers instead of zeros.
- ``run_strix_scan`` accepts an externally-built ``AgentMessageBus``
+ an explicit ``model`` arg. The TUI pre-creates the bus so its
stop and chat-input handlers can submit ``bus.send`` /
``bus.cancel_descendants`` coroutines onto the scan thread's loop
via ``asyncio.run_coroutine_threadsafe`` — replacing the
TODO-stub no-ops.
- ``model`` config now propagates root → context → child agents in
``create_agent`` (was hardcoded fallback).
Dead-code removal:
- Deleted the ``load_skill`` tool entirely (host module, sandbox
module, TUI renderer, tests). The legacy implementation reached
into a global ``_agent_instances`` registry that no longer exists;
the post-migration stub returned ``success=True`` without
injecting anything — pure theater. Skills are still preloaded via
the system prompt at scan-bring-up.
- Dropped ``tenacity`` and ``xmltodict`` from
``[project.dependencies]`` — neither is imported anywhere
post-migration.
- Stripped the system prompt's "use the load_skill tool" lines.
Tests: 278/278 passing. Removed two ``load_skill`` test cases and a
``test_tool_registration_modes::test_load_skill_import_...`` assertion
that exercised the deleted module.

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.

Five tool families ported to SDK function tools using the proven
delegation pattern from Phase 2.3:
- web_search (1 tool): asyncio.to_thread around the synchronous
Perplexity request so the 300s API call doesn't block the SDK
event loop.
- file_edit (3 tools — str_replace_editor, list_files, search_files):
these run *inside* the sandbox container in the legacy harness
(sandbox_execution=True), so the SDK wrappers route through
post_to_sandbox rather than importing the legacy module on the
host (which pulls in openhands_aci, a sandbox-only dependency).
- reporting (1 tool — create_vulnerability_report): asyncio.to_thread
around the legacy function, which itself runs CVSS XML parsing,
LLM-based dedup against existing findings, and tracer persistence.
- load_skill (1 tool): legacy adapter passes ctx.context['agent_id']
through. The legacy implementation reaches into _agent_instances,
a global Phase 3 will replace; until then the call degrades to a
structured error rather than crashing.
- finish_scan (1 tool): legacy adapter pattern. Validates non-empty
fields, checks no other agents are still active (via legacy
_agent_graph), persists the four executive sections through the
global tracer.
Tests: 12 new tests in test_sdk_remaining_local_tools.py — registration
checks, web_search delegation + missing-key path, file_edit dispatch
shape verification, vuln-report validation + delegation, load_skill
adapter passthrough, finish_scan validation + delegation. The two
finish_scan tests use a fixture that snapshots/clears the legacy
_agent_graph['nodes'] dict so cross-test pollution from legacy
multi-agent tests doesn't mask the validation path.
Per-file ruff TC002 ignores added for the five new wrapper modules
(same reason as Phase 2.3 — RunContextWrapper must be runtime-importable
for SDK function_schema().get_type_hints()).
