What the skill teaches
A skill from Slack's official plugin for checking that a Slack app the developer has built actually works. It has the agent set up a safe place to test, a developer sandbox or a Free Team and never a workspace with real users, run health checks with slack doctor and slack manifest validate, start the app with slack run (or a plain Bolt app without the CLI on a best-effort basis), then read the app's source to list its commands, shortcuts, events and modals and turn each into a step to try in Slack and confirm.
Capabilities
- Run slack doctor and manifest validation checks
- Start an app in a developer sandbox with slack run
- Derive test steps from an app's listeners
- Confirm commands, events and modals respond in Slack
