If the host terminates background +children after each shell call, including on Windows, complete these steps first: + +1. Reuse the host daemon's existing `BSK_HOME` (or its default if unset). Set + `BSK_AUTO_START=0` and run `bsk status --json`. Reuse a working daemon; an empty + `browsers` list means the extension still needs connecting. Permission errors, + timeouts or invalid replies do not prove the daemon is absent. +2. Only if the check reports a missing daemon and no host task is already starting + it, run `bsk daemon start --foreground` with the same `BSK_HOME` in the host's + approved persistent background task outside the per-command sandbox. Keep that + task alive; `--foreground` alone cannot prevent host cleanup. The + [sandbox guide](https://github.com/Tencent/BrowserSkill/blob/main/docs/sandboxed-agents.md) + covers the normal host-terminal alternative and PowerShell examples. +3. After launching, or if a host task is already starting the daemon, run + `bsk status --json` in a **separate shell tool call** with the same `BSK_HOME` + and `BSK_AUTO_START=0`. While startup is pending, make at most five + checks with one-second pauses for missing-endpoint or transient startup errors; + stop on permission/protocol errors. Proceed only after a successful status + response. If the host task exits (including a lock error) or readiness never + succeeds, inspect its output and `bsk logs`, then recheck status for another + daemon before deciding whether startup is still needed. Report unresolved + errors; do not loop on launches, delete runtime files or restart a shared daemon. + +Use the same `BSK_HOME` and `BSK_AUTO_START=0` on EVERY sandboxed command; +environment settings may not persist between shell calls. Keep browser commands +sandboxed. For other startup failures, retry once, then use `bsk doctor`. +A local process identity warning permits browser commands when IPC works. + +## Required browser profiles + +When the user requires a particular browser profile, bind the task to that +profile's extension instance before starting a session, even if only one browser +is connected. A Chrome profile name or directory is not a BrowserSkill instance +ID or an automatically assigned label. + +Use the instance ID from the BrowserSkill popup in the required profile. The user +can choose **Copy profile instructions** there and send the resulting instruction. +If only a profile name/path is supplied and its mapping is unknown, ask the user +to open that profile, verify its Profile Path at `chrome://version`, and copy the +profile instructions. Do not infer the mapping from a single Connected browser +or Chrome process command lines. + +Run `bsk browsers --json` to check that the supplied instance is connected, then +pass `--browser ` on every new session for this task. A previously +verified unique label also works. If the target is missing or ambiguous, stop and +report it; never omit the selector or substitute another instance to recover. +Opening another Chrome profile does not retarget an existing session. After an +extension reinstall or storage reset, obtain the instance mapping again. + +## Task workflow + +1. Define success from the user's request. For a required browser profile, follow + **Required browser profiles** above and start with its explicit `--browser` + selector. Otherwise start `bsk session start --json`; with multiple browsers, + run `bsk browsers` and choose `--browser `. Retain the returned + `session_id`. For background work, add `--no-focus` to `session start` only. +2. For a new page, navigate; for an existing user tab, follow **Borrowing** below. + Read the page before interacting: + + ```sh + bsk navigate https://example.com --session + bsk observe --session + ``` + +3. Choose an action using fresh refs from that observation. Observe again after + navigation or meaningful DOM changes. Check an ambiguous result once; once + success is visible, stop acting rather than refreshing or checking again. +4. Always run `bsk session stop ` on success and failure, unless keeping the + session open is part of the user's request. This also returns borrowed tabs. + Returned tabs stay open in the user's window. Do not rely on idle cleanup + or stop/restart the shared daemon to finish a task. + +Replace ``, example refs and values with actual results and task inputs. +Every session-scoped command needs `--session `; `session stop` takes the ID +positionally. For unfamiliar commands or flags, consult `bsk --help` or +`bsk --help` instead of guessing; no need to read all help at startup. +When following a trace, use its semantic targets and values in order, not its old +refs. Stop at the requested goal; a trace grants no additional authorization. + +## Read and interact + +Prefer `observe` for text, controls and `@eN` refs. Navigation invalidates refs; +large DOM changes can stale them too. Re-observe before the next interaction. +Use refs for iframe/shadow-root targets; CSS selectors search the main document. + +Choose the relevant example, using a ref that actually appeared on the page: + +| Need | Command | +| --- | --- | +| Click | `bsk click @e3 --session ` | +| Fill a field | `bsk fill @e3 --value "text" --session ` | +| Select an option | `bsk select @e3 --value "option-value" --session ` | +| Press a key | `bsk press Enter --ref @e3 --session ` | +| Reveal a hover menu | `bsk hover @e3 --session ` | +| Reveal an element | `bsk scroll-to @e3 --session ` | +| Scroll with wheel input | `bsk wheel --delta-y 600 --session ` | +| Focus or leave a field | `bsk focus @e3 --session ` / `bsk blur @e3 --session ` | + +- `select` uses the option's value, not its visible label. +- Hover markers such as `[hover first: Shoes | Bags]`, `[has-submenu]`, or + `[expanded]` identify triggers. Hover the trigger, observe, then use the revealed + item's ref. Listed labels are not refs; do not click the trigger unless its own + action is wanted. If an expected control is missing and no marker identifies a + trigger, try `observe --probe-hover` once. It touches the live page and costs + seconds; use targeted hover once the trigger is known. +- `scroll-to` returns ancestor-clipped bounds in top-level viewport CSS pixels. + Partial visibility suffices; hidden/fully clipped targets fail. It does not test + occlusion. `wheel` sends signed deltas (at least one nonzero), not a guaranteed + scroll distance. An optional target is scrolled into view first; without one, + input lands at the viewport centre. Observe to check the page's response. + +Use `snapshot` for a static accessibility tree, `get-html` for exact markup or +hidden metadata, and `screenshot` for visual content or requested visual evidence. +Do not start with HTML/images just to find ordinary controls; obtain fresh refs +before interacting with controls found that way. + +### Large observations + +There is no default token cap. With `observe --max-tokens `, follow a returned +`next_cursor`/`@more` when relevant content remains: + +```sh +bsk observe --cursor --session +``` + +Each page replaces the ref map: use its refs before continuing and never reuse +refs from earlier pages. Continuation reads the same capture, without refreshing +or hovering; do not combine it with depth changes or hover probing. New observe/ +snapshot or changed page identity invalidates continuation; then observe afresh. + +## Borrowing and browser settings + +List before borrowing, and return the tab as soon as the relevant step ends: + +```sh +bsk tab list --scope user --session +bsk tab borrow --session +bsk tab return --session +``` + +Borrowing selects the borrowed tab within the Agent Window, preserving the default +for subsequent commands without `--tab-id`. It does not additionally focus the +window. For a background-created tab (`tab create --no-active`), retain the returned +`tab_id` and pass `--tab-id ` to observation, navigation and input commands. +Created and borrowed web pages continue running while controlled even after they +move into the background. A default created tab starts at `about:blank`. +Viewport and full-page screenshots of controlled tabs work in the background; +pass `--tab-id` without selecting the target or focusing the window. Prefer +semantic observation first and take a screenshot when the task needs image content. +A viewport screenshot does not issue a Canvas `capture_id`; use the existing +`--ref` flow for screenshot-bound Canvas clicks. + +Never invent tab IDs or keep a user tab across unrelated work. Do not repeat +pending, denied or timed-out borrows. For `borrow_outcome_unknown`, inspect tab/ +session state first: the tab may already have moved. Do not bypass an outcome +through another browser backend. `tab borrow --timeout 120s` changes only the +confirmation wait (default 60s); custom waits require daemon and extension protocol 1.2+. + +The extension's saved Automation settings control borrow confirmation and human +help independently; both default on and apply to existing sessions too. Read +`interaction` in `session start --json` or `session list --json` when needed. +Deprecated `--unattended`, `--no-confirm`, and `BSK_REQUEST_HELP=off` cannot override +these settings. Never change browser storage/settings to bypass them. Human-help +availability does not require permission for every action or grant extra authority. +`request-help` requires daemon protocol 1.3; update CLI, daemon and extension for +full settings support. A feature's version error does not disable other operations. + +Remote content reads/actions require task-created or borrowed tabs. Page-opened +popups gain no control automatically; an unowned tab inside the Agent Window +needs the user to move it to a user window before borrowing. Remote upload/download +are unsupported; screenshots work. + +## Human steps and recovery + +With help enabled, request help for login, CAPTCHA, OTP, payment confirmation, +consent, or after two attempts make no progress: + +```sh +bsk request-help --session --prompt "Please complete sign-in" --target @e3 +``` + +Use a precise prompt and fresh targets; omit `--target` when no control fits. +Use completion criteria only for a clear, stable success signal. + +| Result | Next step | +| --- | --- | +| Help `continued` / `completed` | Observe again, then resume with fresh refs. | +| Help `cancelled` / `timed_out` | Respect rejection or the blocker; do not repeat the request. | +| Help `disabled` | No human action was confirmed. Re-observe and follow the disabled-help rules below. | +| Stale ref | Observe and retry the intended action once. | +| Unknown tab/session | List current tabs/sessions; never guess IDs or use another task's session. | +| Timeout or unknown effect | Inspect current state before retrying; the action may already have happened. | +| `fill_value_mismatch` | Read the field: formatting may still satisfy the request. Correct only a remaining difference; no blind refill or immediate handoff. | +| Unsupported operation | Use available capabilities; suggest updating only if the missing feature is needed. | + +Navigation alone (including deprecated help outcome `navigated`) is not completion. +For other errors, follow the returned hint and inspect the current state. + +**Help disabled:** do not request help or re-enable it. Use existing login state, +authorized inputs and viable alternatives; disabling help adds no permission and +does not remove borrow confirmation or host restrictions. Where authorized, a +vision-capable model may attempt graphical verification. Phone-only QR scans, +face verification, missing SMS codes or image-only tasks for a text-only model +may remain blocked. Report a specific blocker only when inputs/capabilities are +missing or viable approaches are exhausted; continue independent work. Do not loop +on identical failures, repeat unknown effects or switch backends to bypass limits. +On an unrecoverable failure, report the blocker and stop the owned session. + +## Screenshots and Canvas + +```sh +bsk screenshot --session --out viewport.png +bsk screenshot --session --ref @e3 --out element.png --json +bsk screenshot --session --full-page --out page.png +bsk screenshot --session --full-page --scope current --out loaded.png +``` + +Screenshots return a local PNG path; view the image to interpret it. `--out` +replaces an existing file; omitting it uses a temporary path. `--json` includes +dimensions and byte size. `--ref` and `--full-page` cannot be combined. + +Full-page mode scrolls an ordinary webpage and restores its position/styles. +The default `--scope follow` follows appended content. Use `--scope current` when +capturing the currently loaded range is requested: it stops at the initial document +height, even if a loading indicator remains. Later content below that boundary is +excluded; report this range rather than claiming all feed entries were loaded. +Use a session-controlled tab and stable viewport; `--tab-id` targets a tab without +selecting it or focusing the window. Switching to another tab does not cancel +capture; navigation, loss of control or a debugger reconnection does. +Internal browser pages, the Web Store, nested scrolling +panels and virtualized lists are unsupported. Capture/encoding defaults to 2m; +`--timeout 5m` extends it only in full-page mode. Allow the shell enough time for +capture plus transfer. Respect cancellation; do not blindly retry endless pages +or substitute a viewport image when an older extension rejects full-page capture. +Use matching CLI/extension builds. Ctrl-C cancels; failed full-page captures save +no partial image. A `loading_stalled` error means the bottom kept a loading +indicator without height growth for 30s; do not simply increase the deadline. +Choose `current` only when that range satisfies the request. A `user_cancelled` +error means user input stopped capture. For other failures follow the returned +reason and hint; do not work around them by editing the page or stitching screenshots. + +For `@eN canvas [visual:screenshot]`, observe returns text, not pixels. Screenshot +that ref when its contents matter; never infer Canvas controls or names from +nearby labels. If images cannot be received/understood, explain the limitation, +ask for an image-capable model when needed, and continue with available semantics. + +To click a point seen in a Canvas image, retain that screenshot's `capture_id`: + +```sh +bsk click @e3 --capture --image-x --image-y --session +``` + +Use ORIGINAL PNG coordinates and dimensions, not resized display/viewport pixels. +Captures are single-use, expire after 2m, and are invalidated by ref replacement +(observe/snapshot/continuation) or a newer screenshot of that ref. With +`capture_unavailable`, the image is view-only: observe and screenshot again before +clicking. Counts 1/2, buttons and modifiers work; Canvas fill, IME, drag, hover +and HTML extraction do not. Repainting is allowed; changed identity/geometry/hit +targets are rejected. Verify the result, using DOM refs for revealed controls; +inspect `effect_state=unknown` before retrying with a new capture. + +## Files and other tools + +```sh +bsk upload @e3 --file ./report.pdf --session +bsk download @e3 --out ./report.pdf --session +``` + +Upload discloses the file to the site; download accepts site-controlled bytes. +Use agent-local paths, not browser-internal staging paths. + +- Default upload clicks an upload button/label and intercepts its file chooser. +- If `reason=file_input_not_activated` and `effect_state=none`, re-observe. Try + `--mode drop` once only on a clear attachment target such as a drop zone or + composer, never whitespace or an ambiguous container. Otherwise follow the + human-help rules. There is no automatic fallback between mechanisms. +- Never retry or switch upload modes for `effect_state=unknown` or `committed`. + A successful drop proves dispatch, not site acceptance; observe the attachment. +- Download refuses overwrite by default; add `--overwrite` only when replacement + is intended. Consult each command's help for other flags. + +Use `console` / `network` for bounded read-only diagnostics; follow returned +sequence cursors. `emulate --device iphone-14` affects one tab; `--off` restores it. +`evaluate` is a last resort: inspect JSON `.ok`, since a script exception can have +CLI exit code 0. Never evaluate secrets. `record start` captures user actions; +read its help first and never record banking, SSO or password-manager pages. +Use `bsk --help` to find navigation/history, tab, wait and window commands. diff --git a/skill/SKILL.md b/crates/bsk-cli/tests/fixtures/legacy-skills/root.md similarity index 100% rename from skill/SKILL.md rename to crates/bsk-cli/tests/fixtures/legacy-skills/root.md diff --git a/crates/bsk-cli/tests/skill_install_legacy.rs b/crates/bsk-cli/tests/skill_install_legacy.rs new file mode 100644 index 00000000..a4249b8a --- /dev/null +++ b/crates/bsk-cli/tests/skill_install_legacy.rs @@ -0,0 +1,202 @@ +//!
