Browser commands control the browser panel embedded in each task's detail view. All commands require $SLAYZONE_TASK_ID to be set (automatic in task terminals).

Global flags

  • --panel <state> — visible or hidden. navigate defaults to visible (auto-opens the panel); all other commands default to hidden (operate without showing the panel).
  • --tab <idOrIdx> — target a specific tab. Accepts a 0-based index (e.g. --tab 1) or an opaque tab id (e.g. --tab default). Pure-digit values are treated as indices and resolved via slay tasks browser tabs. Without --tab, commands target the currently active tab.

Commands

  • slay tasks browser tabs [--json] — list browser tabs for the current task.

    • Output columns: active | idx | id | title | url. The active tab is marked with *.
    • Tabs that haven't been loaded yet are marked (not loaded) — they exist in the task's saved state but their WebContentsView hasn't mounted (typically because the panel is closed).

  • slay tasks browser new [url] [--panel <state>] [--background] [--json] — create a new browser tab.

    • Defaults to --panel visible (auto-opens the panel) and switches to the new tab.
    • --background adds the tab without switching focus away from the active tab.
    • Without url, the tab opens about:blank.
    • Prints <idx>: <tabId> <url> (or full JSON with --json). Use the returned id with --tab for follow-up commands.

  • slay tasks browser navigate <url> [--panel <state>] [--tab <idOrIdx>] — navigate the targeted tab to a URL.

    • The only command that auto-shows the browser panel.
    • With --tab, the panel auto-opens and switches to that tab before loading the URL.

  • slay tasks browser url [--panel <state>] [--tab <idOrIdx>] — print the targeted tab's current URL.

  • slay tasks browser screenshot [-o <path>] [--panel <state>] [--tab <idOrIdx>] — capture a screenshot of the targeted tab.

    • Returns the file path of the saved image.
    • -o copies the screenshot to a specific path; without it, prints the temp file path.

  • slay tasks browser content [--json] [--panel <state>] [--tab <idOrIdx>] — get the targeted tab's text content and interactive elements as JSON.

    • Text content truncated to 10k characters.
    • Interactive elements include links, buttons, and inputs.

  • slay tasks browser click <selector> [--panel <state>] [--tab <idOrIdx>] — click an element on the targeted tab by CSS selector.

    • Returns the tag name and text of the clicked element.

  • slay tasks browser type <selector> <text> [--panel <state>] [--tab <idOrIdx>] — type text into an input on the targeted tab by CSS selector.

  • slay tasks browser eval <code> [--panel <state>] [--tab <idOrIdx>] — execute JavaScript in the targeted tab's context and print the result.

    • Strings are printed as-is.
    • Other values are pretty-printed as JSON.

Targeting notes

  • Default target = the currently active tab. Existing scripts without --tab keep working.
  • When a --tab value cannot be resolved, the server returns 404 with the available tabs listed for discovery. The CLI also prints the available tabs when an index lookup fails.
  • A --tab reference by index can shift if the user reorders or closes tabs. For long-lived scripts that need a stable reference, use the opaque tab id (printed by slay tasks browser tabs).

Workflow tips

A typical browser verification flow:

  1. navigate to the URL
  2. content to inspect the page and find selectors
  3. click or type to interact
  4. screenshot to capture the result

For multi-tab flows, use slay tasks browser new <url> to spawn additional tabs, then pass the printed tab id (or the index from tabs) via --tab to subsequent commands.
