tests - set up unit or browser testing

Context reuse: Reuse any required file already loaded in project instructions or the current session. Read it again only if absent, changed, or exact current bytes or line references are needed.

First action: Before project inspection, preflight, or any other tool call, publish running to blueprint/.state/run.json using the dashboard activity contract in AGENTS.md. Use tests as the command for either setup mode.

Select the setup

• /tests or /tests unit: set up stack-native unit testing. Read and follow reference/unit.md only.
• /tests browser: set up a repeatable browser harness. Read and follow reference/browser.md only.
• An explicit natural-language request to set up browser or end-to-end testing selects browser setup too. A runner name alone never selects browser setup. For example, /tests Playwright remains a unit request with a runner preference to clarify, not permission to install browser automation.
• If the user requests both modes, ask which to set up first. Complete one setup at a time. If the requested mode is unclear, clarify before editing.

Load only the selected reference. Do not read both references preemptively. Treat any remaining runner or stack arguments as preferences to verify against project files, never as permission to expand the selected setup.

Follow the selected reference's inspection, approval, verification, and report steps. Unit setup may add tests to an existing Verify command; browser setup must not add its slower gate to Verify or CI without a separate request or an existing project requirement. Neither mode creates CI just by being invoked. Do not commit, merge, push, publish, or begin product feature work.
