The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
doppel_batch ~159
Apply a SEQUENCE of actions (click/type/press_key/hover) in ONE call, in order. PREFER THIS over separate click/type calls whenever you can already see the targets in the current snapshot - e.g. filling a form, ticking several checkboxes, or 'pick an option then click Continue'. Each separate tool call costs a full model round-trip; a batch is one. Refs come from the latest snapshot, so all targets must exist on the SAME page (a batch can't span a navigation). Stops at the first failed op and reports which one. Returns one snapshot at the end.
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a snapshot after the batch. Default true. |
| ops | array | yes | Ordered list of actions. |
No output schema declared.
No examples provided.
doppel_cleanup_tabs ~92
Close leftover Doppel automation tabs. By default only the generic 'Doppel' / 'Doppel Test' groups (debris from past sessions), leaving purpose-named task groups alone. Pass all:true to also close every purpose-named Doppel task group. Non-Doppel tabs and groups are never touched.
| Name | Type | Req | Description |
|---|---|---|---|
| all | boolean | – | Also close purpose-named Doppel task groups, not just the generic ones. |
No output schema declared.
No examples provided.
doppel_click ~87
Click an element by its [ref] from the latest snapshot. Waits until it's actionable, then uses trusted native input. If you already know several actions from this snapshot, prefer doppel_batch to run them in one call.
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a fresh snapshot after clicking. Default true. |
| ref | integer | yes | The [ref] number from a snapshot |
No output schema declared.
No examples provided.
doppel_close_tab ~36
Close a tab Doppel controls and drop its session.
| Name | Type | Req | Description |
|---|---|---|---|
| tabId | integer | yes | The tab id from doppel_list_tabs |
No output schema declared.
No examples provided.
doppel_console ~221
See the page's console output + JS errors, captured read-only. By default shows browser-level problems (errors, warnings, failed network/CSP/deprecation), which is fully stealthy. Page console.log/info is NOT captured unless you set `pageConsole:true`, which enables the CDP Runtime domain (detectable by a hostile page while on, so off by default; captures from that point forward). Uncaught JS exceptions are merged in as errors; consecutive duplicates collapse with [xN].
| Name | Type | Req | Description |
|---|---|---|---|
| grep | string | – | Keep messages whose text matches this substring or regex. |
| includeStack | boolean | – | Include stack traces (capped ~50 frames). |
| level | string | – | Minimum severity to show. Default 'warn' (warnings + errors + failures). |
| limit | integer | – | Max messages. Default 50. |
| offset | integer | – | Skip the first N matching messages (paginate). |
| pageConsole | boolean | – | Capture page console.log/info too (enables Runtime; detectable while on). Set false to turn it back off. |
No output schema declared.
No examples provided.
doppel_hover ~64
Hover the mouse over an element by its [ref] (reveals menus/tooltips). Waits until it's actionable.
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a fresh snapshot after hovering. Default true. |
| ref | integer | yes | The [ref] from a snapshot |
No output schema declared.
No examples provided.
doppel_list_tabs ~27
List the tabs Doppel controls (its tab group), with URLs and which is active.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
doppel_navigate ~92
Navigate the active tab: go to a URL, or go back/forward/reload. Waits for load. Returns the final URL plus a fresh page snapshot (by default).
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a fresh snapshot after navigating. Default true. |
| type | string | – | Navigation type. Default 'url'. |
| url | string | – | Absolute URL (required when type is 'url'). |
No output schema declared.
No examples provided.
doppel_network ~424
See the page's network activity, captured read-only from the moment the tab attaches. Without `reqid`, returns a compact one-line-per-request list; pass `reqid` for full detail plus the response body. Successful static assets (images/fonts/scripts/css) are hidden unless `includeStatic`. Filter with `grep` (URL), `status`, `method`, `resourceType`, `failedOnly`, `xhrOnly` (just API calls), or `sinceLastAction` (only what the last click/type/navigate triggered).
| Name | Type | Req | Description |
|---|---|---|---|
| body | string | – | With reqid: which body to include. Default 'response'. |
| failedOnly | boolean | – | Only failed requests (transport error or status >= 400). |
| grep | string | – | Keep requests whose URL matches this substring or regex (case-insensitive). |
| includeStatic | boolean | – | Include successful images/fonts/scripts/css (hidden by default). |
| limit | integer | – | Max requests in the list. Default 50. |
| maxBytes | integer | – | With reqid: truncate inlined bodies to N bytes (default 10000). |
| method | string | – | HTTP method, e.g. GET, POST. |
| offset | integer | – | Skip the first N matching requests (paginate). |
| reqid | integer | – | Drill into one request by its [id] from the list (full detail + body). |
| resourceType | string | – | doc | css | img | script | font | xhr | fetch | ws | media | other. |
| saveToFile | string | – | With reqid: write the FULL response body to a file (filename only) in the Doppel captures dir (~/.doppel/captures or $DOPPEL_CAPTURE_DIR), instead of inlining it. |
| sinceLastAction | boolean | – | Only requests triggered since the last click/type/navigate. |
| status | string | – | Status filter: "404", "5xx", ">=400". |
| xhrOnly | boolean | – | Only XHR/fetch requests (the API-call case). |
No output schema declared.
No examples provided.
doppel_new_tab ~125
Open a new tab (background, no focus stealing) and make it active. Optionally load a URL. Pass `group` to name the tab group by the task's purpose (e.g. '27in Monitor'); tabs sharing a group cluster together.
| Name | Type | Req | Description |
|---|---|---|---|
| group | string | – | Short purpose label for the tab group, e.g. '27in Monitor', 'Job Apply'. Defaults to 'Doppel'. |
| includeSnapshot | boolean | – | Return a snapshot after opening. Default true. |
| url | string | – | URL to load. Default about:blank. |
No output schema declared.
No examples provided.
doppel_press_key ~72
Press a special key (Enter, Tab, Backspace, Delete, Escape, Arrow keys) via trusted native input.
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a fresh snapshot after the keypress. Default true. |
| key | string | yes | Key name, e.g. Enter, Tab, ArrowDown |
No output schema declared.
No examples provided.
doppel_screenshot ~91
Screenshot the current page (PNG by default). Returns the image. Prefer doppel_snapshot (text) when possible; use this only when you need to SEE pixels.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | – | Image format. Default png. |
| fullPage | boolean | – | Capture the full scrollable page, not just the viewport. |
| quality | integer | – | Quality 0-100 (jpeg/webp only). |
No output schema declared.
No examples provided.
doppel_scroll ~120
Scroll an element into view by its [ref] - e.g. to scroll to the last item of a list to trigger lazy-loading / infinite scroll, then re-snapshot. The snapshot already captures the whole page (all elements, on- or off-screen) and clicks auto-scroll into view, so use this only to trigger scroll-driven loading, not to 'see more'.
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a fresh snapshot after scrolling. Default true. |
| ref | integer | yes | The [ref] of the element to scroll into view. |
No output schema declared.
No examples provided.
doppel_select_tab ~63
Switch the active tab to another tab Doppel controls (tabId from doppel_list_tabs).
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a snapshot of the newly active tab. Default true. |
| tabId | integer | yes | The tab id from doppel_list_tabs |
No output schema declared.
No examples provided.
doppel_set_group ~79
Name the current tab's group by the task's PURPOSE (e.g. '27in Monitor', 'Job Apply'), not the site. Call this at the start of a task so the group chip reads as what you're doing instead of 'Doppel'.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | Short purpose label, e.g. '27in Monitor'. |
No output schema declared.
No examples provided.
doppel_snapshot ~244
Capture a structured accessibility snapshot of the current page. Elements are tagged with a [ref] for doppel_click/doppel_type; refs stay stable across grep/offset within a snapshot. Fast: no screenshot. On dense pages (search results, shopping) use interactive:true and/or grep to cut noise, and offset to page through results.
| Name | Type | Req | Description |
|---|---|---|---|
| grep | string | – | Keep only elements whose printed line matches this text or regex (case-insensitive), e.g. 'Dell', 'button', or 'button "S"'. |
| interactive | boolean | – | Only actionable elements (links/buttons/inputs); skips headings/static text/lists. Best for dense pages. |
| limit | integer | – | Max elements to return. Default 500; 300-1000 is a good range. Prefer interactive/grep over a huge limit. |
| offset | integer | – | Skip the first N matching elements (paginate a long page). |
| within | – | – | Serialize only part of the page: a [ref] to scope to that element's subtree, or a container role like "dialog", "form", or "navigation" to scope to that region. Ignores the rest. |
No output schema declared.
No examples provided.
doppel_status ~27
Check whether the Doppel browser extension is connected. Call this first if other tools error out.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
doppel_type ~86
Type text into an element by its [ref]. Waits until actionable, focuses it, and inserts trusted text (works with React/controlled inputs).
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a fresh snapshot after typing. Default true. |
| ref | integer | yes | The [ref] of the input/textarea from a snapshot |
| text | string | yes | The text to type |
No output schema declared.
No examples provided.
doppel_upload ~184
Upload local file(s) to a file input WITHOUT opening the native OS file dialog. Point `ref` at the upload control from a snapshot - the file input itself, or the button/label that opens it (Doppel finds the underlying <input type=file>). `path` is an absolute path on this machine; pass an array for a multi-file input. Fires the real change event, so the page reacts exactly as if a human picked the file.
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a fresh snapshot after uploading. Default true. |
| path | – | yes | Absolute path to a local file (must be under Downloads/Documents/Desktop/Pictures/temp or $DOPPEL_UPLOAD_DIRS), or an array for a multi-file input. |
| ref | integer | yes | The [ref] of the upload control (the file input, or the button/label that opens it). |
No output schema declared.
No examples provided.
doppel_wait_for ~105
Wait until specific text appears on the page, or for a fixed time. Use after an action that loads content.
| Name | Type | Req | Description |
|---|---|---|---|
| includeSnapshot | boolean | – | Return a snapshot after waiting. Default true. |
| text | string | – | Text to wait for (case-insensitive substring). |
| timeMs | integer | – | Or wait a fixed number of milliseconds (max 60000). |
| timeoutMs | integer | – | Max wait when using 'text' (default 10000). |
No output schema declared.
