Three new modules that wire Phases 0-4 into a runnable Strix scan:
- strix/agents/sdk_prompt.py: standalone Jinja-based system prompt
renderer. Reuses the existing strix/agents/StrixAgent/system_prompt.
jinja template (508 lines, the actual production prompt) so behavior
parity with the legacy LLM._load_system_prompt is byte-identical.
Skill resolution mirrors LLM._get_skills_to_load (caller skills →
scan_modes/<mode> → whitebox pair, deduped). Fail-soft: template
errors return empty string and log; agent construction must never
blow up on prompt load.
- strix/agents/sdk_factory.py: build_strix_agent(name, skills, is_root)
assembles an agents.Agent. Root carries finish_scan and stops there;
child carries agent_finish and stops there (C4). Caido tools come
from CaidoCapability automatically — we don't include them in
_BASE_TOOLS to avoid double-registration when the SDK runtime merges
capability tools. model=None so RunConfig drives the model alias
through MultiProvider rather than the SDK default. make_child_factory
returns a closure over scan-level config (scan_mode, is_whitebox,
interactive, scope context) for ctx.context['agent_factory'] — the
Phase 3 create_agent tool calls it with (name, skills) per child.
- strix/sdk_entry.py: run_strix_scan() — the top-level coroutine.
Builds the bus, brings up (or reuses) a sandbox session via
session_manager, builds the root Agent and the child factory, builds
the per-agent context dict, registers the root in the bus, builds
the RunConfig, calls Runner.run, and cleans up the session in a
finally. Cancels descendants before re-raising any exception (C9).
cleanup_on_exit toggle preserves the cached session for resume
scenarios. _build_root_task and _build_scope_context preserve the
legacy StrixAgent.execute_scan task formatting + scope context shape
so the prompt template sees identical inputs.
Tests: 21 new tests (10 for factory + prompt, 11 for entry point).
Factory: root vs child tool list parity, finish_scan/agent_finish
placement, tool_use_behavior dict shape, Caido absence (capability-
provided), make_child_factory closure semantics. Entry point (all
mocked, no real Docker/LLM): wiring shape verification — context dict
carries every field downstream consumers read, session manager called
with correct scan_id, cleanup runs even on Runner.run failure,
cleanup skipped when disabled, scan_id auto-generation, scan-level
config (scan_mode, is_whitebox) flows into the factory. Task and scope
builders verified against the same shape as legacy.
Per-file ruff ignores added: TC002 on sdk_factory (Tool used at
runtime in _BASE_TOOLS tuple), TC003 + PLR0912 on sdk_entry (Path
runtime-imported; _build_root_task's per-target-type branches are
intentional and well-bounded).
