description: Drive Chrome with OpenCLI to inspect pages, interact with logged-in sites, capture API evidence, and manage native tabs, groups and windows. For reusable adapters, see opencli-adapter-author.

Browser tools for agents

Use the capability that fits the task. Discover commands with `opencli list <query>`; read exact arguments with `opencli browser <command> --help -f json`. Run `opencli doctor` when diagnosing a connection problem.

Scope and results

Page commands require `--session <name>`. Reuse that name across a task; different sessions isolate page work. `--profile <name>` selects a Chrome profile when needed. Options can follow command arguments:

opencli browser open https://example.com --session research
opencli browser state --session research
opencli browser click --role button --name Search --session research
opencli browser close --session research

Default output is one JSON value: `{ "ok": true, "data": ... }`. Failures return `{ "ok": false, "error": { "code": "...", "message": "...", "hint": "..." } }` and a nonzero exit code. Diagnostic logs go to stderr. `network --follow` and `console --follow` stream one envelope per line. Help, version and shell completion are inspection/export surfaces; structured help uses `--help -f json`.

Read the returned data and error fields. When `error.outcome` is `unknown`, inspect the affected state before retrying a write.

Page targets and interaction

• `state` returns URL and interactive element refs. `--diagnostics` also reports

page title and available initial-state globals; `--source ax` selects the AX tree.

• `find` locates elements. Interaction targets accept a ref, CSS selector, or

semantic flags such as `--role`, `--name`, `--label`, `--text`, `--testid`.

• Use `--nth` to resolve deliberate multiple matches. On stale refs, read fresh

state or locate the element again; refs describe the observed page.

• `fill` replaces a field and verifies its value; `type` types text. Other actions

include `click`, `select`, `check`, `upload`, `drag`, `keys` and `dialog`.

• `get text|value|attributes|html`, `extract`, `screenshot` and `eval` expose page data.

`eval` executes JavaScript in the page and can mutate state.

• `wait xhr|selector|text|download` observes an expected condition. Consult help for

timeouts and matching rules.

• `tab list|new|select|close` manages session tabs. `--tab` accepts the page identity

returned by these commands; these are different from numeric native Chrome IDs.

• `frames` lists frame targets; `eval --frame` evaluates in a selected frame.

`bind --session research` attaches the current user tab. Bound sessions permit navigation but block tab creation, selection and closure. `unbind` releases the binding without closing the user tab. Owned sessions keep leased tabs until `close` or idle expiry. `--window foreground|background` controls owned windows.

Network and scripts

opencli browser network --session research
opencli browser network --detail RequestKey --session research
opencli browser network --static --session research

`network` returns captured request keys and response shapes. `--detail` reads a cached request; `--filter` selects shapes; `--raw` exposes response bodies. `--static` adds Acorn AST candidates from loaded scripts, with source locations, methods, query/body parameter names and observed request evidence. `EXPR` means an unresolved expression. Static candidates are not executed or proven APIs. Check `analysisComplete`, script errors, omitted scripts and `networkSource`. An empty live capture can reuse a recent cache; reported provenance distinguishes it.

Native Chrome management

Native calls need no session and do not attach a page:

opencli browser chrome describe
opencli browser chrome describe tabs.group
opencli browser chrome call tabs.query '[{}]'
opencli browser chrome call tabs.group '[{"tabIds":[123,456],"createProperties":{"windowId":10}}]'
opencli browser chrome call tabGroups.update '[789,{"title":"Research","color":"blue"}]'

Use numeric IDs returned by Chrome, replacing the example IDs. `describe` lists supported methods, signatures, live permissions and official documentation. Native-created tabs/windows persist. Mutations touching active OpenCLI session tabs or managed groups return `managed_resource_conflict`; ordinary groups can be created, renamed, recolored, moved and dissolved with `tabs.ungroup`.
