release/v1.5.10
release/v1.5.6
release/v1.6.1
| 1 | //! End-to-end headless (`sigit -p`) runs against the real binary. |
| 2 | //! |
| 3 | //! Same harness idea as `tests/acp_permissions.rs`: a scripted OpenAI-compatible |
| 4 | //! SSE endpoint stands in for the model via the `OPENAI_BASE_URL` override, and |
| 5 | //! the BUILT binary is driven like CI would drive it — one `-p` invocation, then |
| 6 | //! assertions on the exit code, stdout, and what the endpoint saw. |
| 7 | //! |
| 8 | //! 1. With `--allow-tool run_command`, the scripted tool call executes and its |
| 9 | //! output travels back to the endpoint as a `role: "tool"` result. |
| 10 | //! 2. Without `--allow-tool`, the ask-level tool is denied, the denial is fed |
| 11 | //! to the model, and the run still exits 0 (the turn completed). |
| 12 | //! 3. An unknown flag is a usage error: exit 2, nothing hits the endpoint. |
