Read-only | Idempotent | Open world | ||
|---|---|---|---|---|
writ_browser_actRuns one batch of actions on an open session and returns the fresh page. Each action is an object, e.g. {"action":"click","selector":"#go"}. DRIVE: navigate, click, fill, type_text, select, check, hover, submit, press_key, scroll, back, wait, wait_for. SEE: query_dom, find_text, read_text, count, get_attributes, inspect, list_candidates, get_dom, get_screenshot. NETWORK: capture_network, get_request, rotate_exit. CODE: evaluate_js, search_scripts, read_script. RECORD: extract {variable,script}, api_call (a flow is built step by step with writ_browser_compose add_flow_step), login_post, probe_write, confirm_write. 2FA: twofa {challenge_method}. A value written {{name}} with its real value in `inputs` becomes a workflow input. Each action's arguments: the session's start answer, or writ_help('writ_browser_act'). | Yes | No | No | Yes |
writ_browser_ask_userHands an open session to the Writ user: kind='captcha' (they complete a security check in the live browser), 'twofa' (they supply the one-time code and Writ types it; the code never reaches this conversation), 'sign_in' (they sign in on the live page; no persona applies) or 'question' (their text answer). The call that opens the ask returns at once with user_link + tell_user to relay; later calls hold up to 60 s and answer answered, waiting_for_user (the same call again) or expired. Their answer is kept if your turn ends first. | No | No | No | Yes |
writ_browser_cancelCloses an open browser session (an open cloud browser bills until it is closed). Unsaved work that did more than visit pages is auto-saved first and the reply names it; discard=true keeps nothing. | Yes | No | Yes | No |
writ_browser_composeAuthors the workflow in an open session beyond a recording: named API functions (define_function with a `flow`, preferred in an API build, or a captured call's index or a lists payload; live-tested as defined; compile_function for an authenticated request), set_inputs, add_steps, test_function, remove_function, remove_step, list. A flow is built in small calls: define_function with its first request, then add_flow_step {function, step, at?} per step, each tested and answered with the step list; a set step's value is read as {ref:'vars.<name>'}. Shapes: writ_help('writ_browser_compose'). | Yes | No | No | Yes |
writ_browser_contextRe-reads an open session: section=page (url, fields, buttons, cleaned DOM), lists (the page's repeating rows with a live-tested define_function payload for writ_browser_compose), map (the evidence of the build the session is bound to). | No | Yes | Yes | No |
writ_browser_live_viewThe live browser card's own access: the card ChatGPT and Claude show under writ_browser_use and writ_record_website calls it to read the session's state and get one-time passes for the session's screencast and its take-over channel. The user watches the page in the card and can take it over there. It is not part of a conversation's work. | No | No | Yes | No |
writ_browser_networkSearches (operation=search, query, method) or reads in full (operation=detail, index) the backend requests the page made after capture_network: the site's real API. writ_browser_act api_call probes one with other values (a `flow`: several requests); an index feeds writ_browser_compose define_function from_index. | No | Yes | Yes | No |
writ_browser_saveSaves the open session as a replayable workflow and closes the browser, in the place its browser ran: the user's desktop library or Writ Cloud. Composed functions become callable API functions, declared inputs become its parameters. The answer carries the steps, the inputs and a run_example; the workflow runs at zero AI cost through writ_run_workflow. A save that references something no run could resolve is refused with the reasons, and the browser stays open. | Yes | No | No | Yes |
writ_browser_sessionsLists the account's open cloud browser sessions (each resumable by its session_id). | No | Yes | Yes | No |
writ_browser_useA REAL CLOUD BROWSER FOR A TASK ON A SITE: the user's signed-in account (a persona_id from writ_personas: the password stays sealed in Writ, and sessions never ask for a password), a click, form, submit or search inside an app, or a page a plain fetch cannot open (login wall, 403, CAPTCHA). Opens the browser and returns the first page; writ_browser_act drives it (Writ runs no model here). Recording is always on: writ_browser_save turns the session into a workflow that replays without a browser, writ_browser_cancel closes it (an open browser bills). The start answer carries the action vocabulary, the recording rules and, with a persona, the 2FA rules. NOT FOR: reading pages (writ_scrape). An API: writ_website_to_api opens this same browser, bound to a build. | Yes | No | No | Yes |
writ_crawl_filesThe original files (PDFs, office documents, images, CSVs) a crawl captured, with short-lived download URLs. | No | Yes | Yes | No |
writ_crawl_siteCOLLECTS a site or a section into a queryable, change-tracked dataset (one row per page). Scope: intent (a section, in plain words), rank_cap=N (the top N items of a listing), seed_urls (known pages), or the whole site capped by page_budget. Modes: markdown (default, no AI), extract_mode='schema' (uniform records), executor='ai' + extract_prompt (per-page understanding, 5x the page rate). A bounded crawl answers with its rows; an open one returns a crawl_id for writ_crawl_status wait=true. NOT FOR: reading a few pages now (writ_scrape). Every option: writ_help('writ_crawl_site'). | Yes | No | No | Yes |
writ_crawl_statusStatus of a crawl by crawl_id; wait=true holds up to 75 s and returns the collected rows when it converges. | No | Yes | Yes | No |
writ_create_automationCreates an automation: on an event (a workflow or crawl completed, a monitor change, a webhook, a schedule) it runs a workflow, sends a notification templated over the event's data, and/or wakes an AI agent. Event, template and webhook options: writ_help('writ_create_automation'). | No | No | No | Yes |
writ_create_http_extractionDrafts or revises a multi-request browserless HTTP extraction (loops, GraphQL, cursor pagination) from captured requests and a plain-language goal. Every option: writ_help('writ_create_http_extraction'). | Yes | No | No | Yes |
writ_create_monitorWATCHES a page for changes: Writ checks it on a schedule and fires change_detected when the page, a CSS selector's text, a value read by `extract`, or a visual zone changes. Returns the monitor_id that writ_wire_monitor connects to an alert, a workflow or an AI task (a price watch takes a threshold there). Without `interval` the answer is needs_input: this plan's options and a tell_user for the user, nothing created. The page is read first: a sign-in answers needs_persona, a bot check offers use_residential. | No | No | No | Yes |
writ_devicesThe user's linked Writ desktops: list, use (scope this connection to one: runs, browsers, personas and monitors then target it), clear, monitors, datasets. | No | No | Yes | No |
writ_diagnose_http_workflowExplains why a saved workflow's run returned nothing or failed: HTTP-lane readiness and, with task_id, the run's requests and responses. | No | Yes | Yes | No |
writ_discovery_statusStatus of a website-to-API build (a guided one, or one started in the Writ app). wait=true is one held call (up to 75 s) that follows the build to its newest rung and returns when it is done or parked. Answers: succeeded (workflow_id, functions, run_example), failed, cancelled, or needs_guidance (the build is the caller's to finish with writ_website_to_api build_id=<id>; its map comes with it). | No | Yes | Yes | No |
writ_export_dataExports a workflow's full data table as CSV or JSON. | No | Yes | Yes | No |
writ_expose_workflow_apiPublishes a saved workflow as a REST endpoint (a POST URL that waits and returns its JSON). Repeated calls reuse it. | No | No | Yes | Yes |
writ_helpThe full reference of any Writ tool (every parameter and its rules) and the complete guide. topic = a tool name (e.g. 'writ_browser_compose', a 'run_<workflow>' tool), 'guide' for the manual (recurring digests, HTTP flow building, buying on a price, crawl modes), 'actions' / 'recording' / '2fa' for the browser rules, 'http_flows' / 'flow_operators' for writing an HTTP flow, or empty for the list of topics. | No | Yes | Yes | No |
writ_list_webhooksThe account's inbound webhook URLs and the automations they fire. | No | Yes | Yes | No |
writ_list_workflowsLists the workflows saved in the Writ account; each runs on demand without live browsing. Returns id, name, declared inputs (with `input_rules`: the values and format an input accepts), schedule, whether it is pinned as its own run_<name> tool, and, for an API with several functions, their names (`functions`, `write_functions`): call one with function_name. | No | Yes | Yes | No |
writ_paymentPays on a site with one of the user's cards; card numbers never reach this conversation. request (site, max_amount, purpose) returns a tell_user and an open_url where the user approves; wait (grant_id or confirmation_id); checkout pauses at the order button for the user's confirmation, then Writ places the order; fill; list (card handles only). Details: writ_help('writ_payment'). | Yes | No | No | Yes |
writ_personasThe user's own accounts on websites (personas): how Writ signs in as them. No password passes through this tool or the conversation, and its answers never ask for one: credentials are typed only into a Writ window. action='list' domain=<site> shows the personas usable there; with none it answers persona_needed: a tell_user for the user, a create_url (a small Writ window with only the sign-in form, pre-filled for the site) and a link_id. action='wait' link_id=<id> is one held call that answers when the user saves it, with its persona_id. Also get, request (a link for another account), sign_in (refresh the session) and record_login. A persona_id works on writ_scrape, writ_crawl_site, writ_browser_use and writ_run_workflow; a desktop persona ('device:...') signs in on that desktop, from its own vault. | No | No | No | Yes |
writ_pin_workflow_toolPins (or unpins) a saved workflow as its own run_<name> tool on this server. | No | No | Yes | No |
writ_record_websiteRecords a repeatable task on a site as a workflow (goal + start url): the same session as writ_browser_use, labelled with its goal, driven with writ_browser_act and saved with writ_browser_save. A goal that asks for an API opens as a writ_website_to_api build instead: the same browser, bound to the build. | Yes | No | No | Yes |
writ_run_saved_crawlRuns a saved crawl; max_age returns its recent data at no cost instead of re-crawling. | No | No | No | Yes |
writ_run_workflowRuns a saved workflow by workflow_id or name and returns its extracted data (it waits by default). The answer's `data` is what the run returned and `records_path` names its records; pass `output` with only the fields the question needs (fields: ['price', 'data.date as date']) for a far smaller answer. Inputs go as top-level fields or under `inputs`; function_name runs one function of a multi-function API (with the sign-in it needs). max_age reuses a recent result at no cost. A write function previews with mutation_mode='dry_run'. Runs sign in as the workflow's persona or persona_id; no password is ever passed. Venue, network, files and output shape: writ_help('writ_run_workflow'). | Yes | No | No | Yes |
writ_saved_crawl_dataReads the data a saved crawl collected on its last completed run, without crawling. | No | Yes | Yes | No |
writ_saved_crawlsLists the crawls saved for re-running, with their scope. | No | Yes | Yes | No |
writ_scrapeREAD PAGES NOW, no browser session: one page (url), up to 20 pages in parallel (urls, on one site or several), or a listing plus its top N item pages (url + top_n). Returns clean markdown in 2-10 s, including pages a plain fetch cannot read: rendered by JavaScript (render_mode='browser'; a read that only got the page's shell says so and gives the retry), behind a bot wall or 403 (an automatic residential retry; render_mode='http' opens no browser, so it never passes a check), or behind the user's sign-in (persona_id). Discussion threads keep their comments. format='html' returns the raw HTML for selectors, for one page or a batch. A page that cannot be read says why (error.code, e.g. scrape_not_found: the URL does not exist on the site) and gives retry_with when another read can help. NOT FOR: a site-wide dataset (writ_crawl_site) or clicking and typing (writ_browser_use). | No | No | No | Yes |
writ_search_dataSearches everything the account's workflows already collected for a term, without running anything. | No | Yes | Yes | No |
writ_set_scheduleSchedules a saved workflow: every_minutes, or kind='daily'/'weekly' with time (HH:MM) and days. functions + inputs schedule chosen functions of a multi-function API. | Yes | No | Yes | No |
writ_update_saved_crawlInspects or changes a saved crawl's settings in place. | Yes | No | Yes | No |
writ_update_workflowInspects or edits a saved workflow: an outline, one function's source, targeted function or step edits, a settings patch. copy_to keeps a linked copy on Writ Cloud or the user's desktop. Every option: writ_help('writ_update_workflow'). | Yes | No | No | No |
writ_website_to_apiTURNS A WEBSITE INTO A CALLABLE API (named functions with inputs, returning JSON), built by the caller in a real browser. url = the page that already shows the rows (search results or a listing, not the home page); goal = the inputs and fields wanted. The call first proposes the user's matching saved workflows and marketplace APIs (skip_existing / skip_marketplace build fresh), then opens a cloud browser bound to the build: capture_network records the site's own calls, writ_browser_network reads them, api_call probes them; a failed probe is evidence, not the end. Functions: HTTP flows first (writ_browser_compose define_function `flow`; writ_help('http_flows')), single requests (from_index) mixed in, DOM extraction last. writ_browser_save, then run_example on two inputs. | Yes | No | No | Yes |
writ_wire_monitorConnects a monitor's change_detected event to an action: action='notify' (channels and recipients the account has configured), 'workflow' (runs a saved workflow), or 'ai_task' (an AI agent opens the page and works `prompt`). A price watch takes `threshold` (+ threshold_op): the action then runs once, when a check reads a price at or below it. Buying at a price (`buy`): writ_help('writ_wire_monitor'). | No | No | No | Yes |
writ_workflow_dataReads a saved workflow's collected data as a table: q filters, run_id picks one run, refs returns full records. | No | Yes | Yes | No |
writ_workflow_runsRun history (status, timing, errors, venue) of one workflow or all of them. | No | Yes | Yes | No |
