   - The experimental `cursor` engine is available through `imports: [shared/cursor.md]`; see [`smoke-cursor.md`](../workflows/smoke-cursor.md) for an example. Requires the `CURSOR_API_KEY` secret. Cursor reads project rules from `.cursor/rules/*.mdc` and respects the root-level `.cursorignore` and `AGENTS.md`; both are protected in the manifest. Use `model: cursor/auto` or a specific model such as `cursor/claude-3-7-sonnet`.
   - The experimental `kiro` engine is available through `imports: [shared/kiro.md]`; see [`smoke-kiro.md`](../workflows/smoke-kiro.md) for an example. Requires the `KIRO_API_KEY` secret. Kiro reads steering documents from `.kiro/steering/` and hook definitions from `.kiro/hooks/`; these directories and `AGENTS.md` are protected in the manifest. Model must use `kiro/` prefix, e.g. `model: kiro/claude-sonnet-4-5`.
   - The `pydantic-ai` engine is available through `imports: [pydantic/pydantic-ai/src/pydantic_ai_harness/gh-aw/pydantic.md@main]`; see [`smoke-pydantic.md`](../workflows/smoke-pydantic.md) for an example. It runs the Pydantic AI `pai` CLI with the `pydantic-ai-harness` coder agent and uses `provider/model` syntax.
-  - The experimental `crush`, `aider`, `goose`, and `custom` (GenAIScript) engines are also available through `imports: [shared/<engine>.md]`; see [`smoke-crush.md`](../workflows/smoke-crush.md), [`smoke-aider.md`](../workflows/smoke-aider.md), and [`smoke-goose.md`](../workflows/smoke-goose.md) for examples. Full list of import-based engines: see `.github/aw/engines.json`.

+Aider is single-turn: implement the imported probes in a small JavaScript file
+at `/tmp/gh-aw/agent/engine-conformance/run-probes.cjs` using SEARCH/REPLACE blocks,
+then execute it with one `node` command in a bash block. The program must read
+the fixture, run the supplied shell probe, invoke
+`mcpscripts` with `spawnSync` and an argument array, and write `result.json` with
+the actual returned values. Preserve nonzero child exit codes. Do not guess
+nonces or replace the supplied probe. Emit the final staged noop in a bash block.
