2026-10-13-temporal-agent-harness-0-5-0-adds-inspectable-agent-dag-scripts-and-code-mode-preflight-checks
0.5.0 adds inspectable agent DAG scripts and Code Mode preflight checks. A model writes or revises a Python flow in the browser editor; a separate execute handler runs it after the user presses Run. Each run_agent starts a fresh subagent with per-step name, instructions, tools and model; asyncio.gather permits parallel steps. The packaged code_mode_type_check API reports syntax/type errors against host signatures without dispatching host tools. At T6 it briefly starts a clean script until first suspension or a short limit and discards it; checking does not mean no script instructions execute. The example uses simulated step tools and defaults its step agent to skip-all.
Channel: preview-or-beta (DAG Studio is a repository example; preflight API is packaged). Half: capability. Date: 2026-09-30.
Operator consequence: Try this when the useful review unit is the generated plan before execution. Inspect the script and per-step tool/model configuration, and set real tool authorization before replacing simulated tools. Preflight validates the executable contract, not the plan’s correctness or authority.
