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()).
