--- summary: 'Execute .peekaboo.json scripts via peekaboo run' read_when: - 'batching multiple CLI steps into a reusable automation script' - 'capturing structured execution results for regression tests' --- # `peekaboo run` `peekaboo run` loads a `.peekaboo.json` (PeekabooScript) file, executes every step via `ProcessService`, and reports the aggregated result. It’s the same engine the agent runtime uses for scripted flows, which makes it ideal for regression suites or reproducing agent traces. ## Key options | Flag | Description | | --- | --- | | `<scriptPath>` | Positional argument pointing at a `.peekaboo.json` file. | | `--output <file>` | Write the JSON execution report to disk instead of stdout. | | `--no-fail-fast` | Continue executing the remaining steps even if one fails (default behavior is fail-fast). | | `--json-output` | Stream the final `ScriptExecutionResult` JSON to stdout (same schema as the saved file). | ## Implementation notes - Scripts are parsed on the main actor via `services.process.loadScript`, so relative paths (`~/`, `./`) resolve exactly as they do when agents run scripts. - Execution delegates to `services.process.executeScript`, which returns a `[StepResult]` containing individual timings, success flags, and error strings; the command wraps those in a summary with total durations and counts. - `--output` writes via `JSONEncoder().encode` + atomic file replacement; if the write succeeds but the script fails, you still get the partial data for debugging. - When any step fails and `--no-fail-fast` is **not** set, the command throws `ExitCode.failure` after printing the summary so CI can register the run as failed. ## Examples ```bash # Run a script and view the JSON summary inline polter peekaboo -- run scripts/safari-login.peekaboo.json --json-output # Capture results for later inspection but keep executing even if a step flakes polter peekaboo -- run ./flows/regression.peekaboo.json --no-fail-fast --output /tmp/regression-results.json ``` ## Troubleshooting - Verify Screen Recording + Accessibility permissions (`peekaboo permissions status`). - Confirm your target (app/window/selector) with `peekaboo list`/`peekaboo see` before rerunning. - Re-run with `--json-output` or `--verbose` to surface detailed errors.
