plain saves passed actions from a coding agent’s app exploration as editable, plain-language YAML, then replays the flow from a terminal.
- For
- Developers turning exploratory agent runs into regression tests
- Worth noticing
- The sample YAML keeps target descriptions and assertions readable, while desktop and mobile setup remain platform-specific.
Field notes
The example spec names an app URL and represents actions with readable targets, values, and expectations; the page offers it as a downloadable file. The integrations are not presented as one portable setup: desktop requires native accessibility permissions, while mobile requires a configured Appium server and an installed app on a device or simulator. The homepage also links to trial results and agent traces, though the supplied extract omits the comparison outcome.
