Do not treat this skill as a generic browsing default. Route from the evidence you need, not from tool preference.

Every task must be classified before you choose a route:

- `static-capable`: the evidence can be produced without live browser state, visible confirmation, or page interaction
- `browser-required`: the evidence depends on rendered state, interaction, live session behavior, or browser-only structures

Only `static-capable` tasks may fall back to static retrieval, `curl`, or other non-browser paths. Once a task is `browser-required`, stay on the browser path and mark missing capability as `blocked` instead of silently downgrading.

## Prerequisite check

This skill is for work inside the user's live browser session, not for launching a separate fresh automation browser.

Before doing browser automation, confirm that your environment already has access to a live browser stack that can provide the capabilities the task depends on.

## Treat as `browser-required` by default

- `localhost`, `127.0.0.1`, or benchmark-style local fixtures
- uploads, downloads, drag-and-drop, hover, keyboard-native entry, or visible confirmation states
- same-origin iframe inspection, Shadow DOM inspection, `details` / collapsed evidence, or lazy-loaded content
- any task where "what the page visibly shows" is itself the evidence

## Decision guide

1. Decide whether the task is `static-capable` or `browser-required`
2. If `static-capable`: stay on the cheapest route that still satisfies the evidence target
3. If `browser-required`: load the browser playbook reference
4. If browser-required capability is uncertain: check the browser capability matrix
5. If the user has an active browser debugging context: prefer handoff from that context

## Hard rules

- Use browser interaction only when live browser state is part of the evidence or required action
- Once a task is `browser-required`, do not silently downgrade
- Prefer site-generated DOM links over hand-built URLs
- Prefer MCP-native actions over script-driven interaction
- Only close pages you created
- Do not use `curl`, `Invoke-WebRequest`, or shell HTTP fetches for `browser-required` tasks
- Do not treat a generic page-opening tool as evidence that localhost deep interaction is available

## Experience loop

For `browser-required` work:
1. Check if a matching note exists under `references/site-patterns/` for the target domain
2. If a note exists, read it before the first meaningful browser mutation
3. During the run, watch for verified site-specific facts
4. Before finishing, decide whether the run produced a reusable fact and update the note
