Closes the "click @e20 hits the sibling element" bug. Real-world
example: snapshot shows @e20=[button "Add post"] next to
@e17=[button "Post all"]. By the time you click @e20, React has
re-rendered — and React often re-uses the same <button> DOM node
across renders, just updating its accessible name. The cached
backendNodeId still resolves to a real, well-positioned node, so
the click lands cleanly. It just lands on what is now the "Post all"
button, silently submitting the entire thread instead of adding a
draft row.
Before every ref-based interaction (click / fill / type / hover /
select / drag — anything routing through resolve_element_center or
resolve_element_object_id), call Accessibility.getPartialAXTree for
the cached backendNodeId and check role + name still match the
snapshot entry. On mismatch, abort with an error that names both
labels:
Ref @e20 no longer matches its snapshot. Was [button "Add post"],
now [button "Post all"].
...Take a fresh snapshot, then re-target.
If the node is gone (CDP fails / no AX node), we silently fall
through to the existing "find by role+name" recovery path, so this
guard never makes a working flow worse.
Adds one CDP roundtrip per ref interaction (~5–20ms). Disable with
AGENT_BROWSER_VERIFY_REF=0 if you control the page lifecycle and
need the latency back.
Pairs with the click paint-settle fix: even with that, a thread builder
that clicks "Add post" can race a misbehaving handler that closes the
parent modal instead of mounting the next textbox. To make that case
observable instead of silently corrupting the next inserttext, you can
now write:
click @add-post
wait .modal --gone --timeout 2000 # asserts modal stays mounted
inserttext "tweet 3"
If the modal vanished, `wait --gone` succeeds — flip the assertion to
`wait .modal` (default visible) to fail-fast on disappearance.
Implementation just sets `state: "detached"` (or "hidden") on the wait
command — daemon-side `wait_for_selector` already supported these
states; only the CLI parser was missing the user-facing flag.
Also accepts `--detached` as alias for `--gone` to match the daemon's
internal vocabulary.
Closes a real-world race that broke X multi-tweet thread composition
(and similar SPA flows): clicking "Add post" returned immediately,
inserttext fired before React had committed the new textarea, the
keystroke landed on the dialog wrapper, and X interpreted the stray
input as a request to dismiss the modal.
After mouseReleased we now wait for two requestAnimationFrame ticks
plus a microtask boundary (~33ms at 60fps, bounded). That's enough
for React/Vue/Svelte to commit any state update scheduled by the
click handler. Errors during the wait are swallowed — a click never
fails because of post-processing.
Opt out for perf-sensitive scripts that don't drive SPA UIs:
AGENT_BROWSER_CLICK_WAIT_STABLE=0
The previous lockfile had ~11k lines of transitive deps for
packages/dashboard which we deleted in 86c4cff. Re-running pnpm install
shrinks it to ~24 lines (just husky for git hooks).
Before: after `npm i -g` upgrade, the next agent-browser command would
detect daemon version mismatch, kill the old daemon, spawn a fresh one,
and connect to a brand-new about:blank tab. The user's previous
navigation state was silently lost — `get url` returned about:blank
even though the user's Chrome was still on the same page.
Now: before killing the old daemon, the CLI synchronously asks it for
its current URL via the existing socket. If non-empty and not
about:blank, it's persisted to a `.restore-url` sidecar in the socket
dir. After the new daemon spawns and auto-connects, it reads the
sidecar (read-and-delete), navigates the fresh tab to the saved URL,
and prints `⚠ Restored previous URL: <url>`.
Manual `agent-browser close` does NOT write the sidecar, so a clean
shutdown won't trigger surprise navigation. The sidecar is consumed on
read regardless of whether navigation succeeded, so a stale entry
can't haunt later auto-launches.
Before, `agent-browser find role button --name Submit` errored at the
daemon side with the cryptic `Unknown subaction: --name`. Now it errors
at parse time with the offending flag echoed back, the list of valid
actions (click, fill, check, hover, text), and a "Did you mean" hint
showing where to put the action verb.
Backwards compat: `find role button` (no flags, no action) still
defaults to click — only `--xxx` in action position errors.
npm 10+ strips bin paths starting with ./ as invalid, leaving the
package with no executable entries (so `npm i -g` doesn't put any
binary on PATH). Match the upstream form `bin/agent-browser.js`.
- Add fork binary names (agent-browser-stealth, abs) to allowed-tools
in all 6 SKILL.md files so installs into Claude Code / Cursor don't
prompt for permission on every command
- Document `npx skills add leeguooooo/agent-browser-stealth` in README
- Bump README upstream-base mention from v0.24.0 to v0.27.0
These directories are TypeScript-side tooling that the fork dropped at
v0.24.0 to keep the repo focused on the stealth CLI binary. Upstream
either kept evolving them (docs, packages/dashboard) or added new ones
(evals/) — they came back during the v0.27.0 rebase, so prune again.
Also include skill-data/ in package.json `files` so the specialized
skills (electron, slack, dogfood, etc.) that upstream relocated from
skills/ to skill-data/ still ship in the npm tarball.
Key insight: ANY JS-level modification to navigator.webdriver is detectable
by creepjs's lieProps system. The only undetectable approach is
Emulation.setAutomationOverride at the CDP protocol level, which tells
Chrome to natively return false for navigator.webdriver.
In CdpAttach mode, we now inject ZERO JavaScript patches — the browser's
real fingerprint is already perfect. Only the CDP protocol command is needed.
CreepJS results now match manual Chrome exactly:
- 0% headless (was 33%)
- 0% stealth (unchanged)
- 25% like headless (Chrome baseline, same as manual)

CreepJS detects three things for webDriverIsOn:
1. Property deletion (navigator.webdriver === undefined)
2. Value check (!!navigator.webdriver)
3. Lie detection (descriptor tampering via lieProps)
Changed from delete/defineProperty-value approach to replacing the CDP
getter with a getter returning false, matching the native descriptor shape.
Note: 33% headless in CreepJS is a CDP-inherent signal (lieProps detects
the getter replacement). This cannot be eliminated at the JS layer since
CDP sets the webdriver getter before init scripts run. Real-world impact
is minimal — Cloudflare Turnstile passes successfully.
Also confirmed: Chrome's remote_debugging preference in Local State
persists across restarts, so users only need to enable CDP once via
chrome://inspect/#remote-debugging.

- CdpAttach mode: only removes navigator.webdriver (user's real Chrome
already has genuine fingerprint, heavy patches create detectable lies)
- FullLaunch mode: applies all 32 patches (new Chrome needs full coverage)
- Improved webdriver removal: uses Object.defineProperty to override CDP
getter on Navigator.prototype, not just delete
- CreepJS results: 0% stealth (was 20%), hasIframeProxy: gone

* feat(react): first-class React introspection, Web Vitals, and nextjs skill
Add React-general and web-universal features as first-class agent-browser verbs
(react tree/inspect/renders/suspense, vitals, pushstate). Genuinely Next.js-specific
workflows (PPR cookie protocol, /_next/mcp bridge, dev-server endpoints) ship as
a new `nextjs` skill that composes the primitives. No new runtime dependencies -
the React DevTools installHook.js is vendored (MIT) and include_str!'d into the
binary.
New commands:
react tree Full React component tree (depth id parent name)
react inspect <fiberId> Props, hooks, state, source for one fiber
react renders start|stop Fiber profiler with Insts/Mounts/Re-renders/Self/DOM
+ prev->next change details
react suspense Suspense boundaries + classifier (client-hook,
request-api, server-fetch, cache, stream, framework)
+ root-cause grouping + recommendations
vitals [url] LCP/CLS/TTFB/FCP/INP + React hydration phases
pushstate <url> Generic SPA client-side navigation
removeinitscript <id> Remove a script registered via addinitscript
New launch flags:
--init-script <path> Register init scripts before first navigation
(repeatable; env AGENT_BROWSER_INIT_SCRIPTS)
--enable <feature> Built-in init scripts; currently react-devtools
(repeatable; env AGENT_BROWSER_ENABLE)
Other primitives:
network route ... --resource-type <csv> Filter by CDP resource type
cookies set --curl <file> Auto-detects JSON/cURL/Cookie-header

Before this change, the main skill served by the CLI (`agent-browser
skills get agent-browser`) was a ~40-line discovery stub whose content
was essentially "run `agent-browser skills get <name>` before doing
anything." Agents already inside the CLI got no signal from it — the
content they needed to actually use the tool lived only in the `--full`
references.
Split the two jobs apart:
- **`skill-data/core/`** (new) — the runtime usage guide. 420-line
`SKILL.md` covering the snapshot-and-ref loop, common workflows
(login, extract, screenshot, multi-tab, sessions, iframes, dialogs),
waiting strategies, element selection strategies, troubleshooting,
and when to load a specialized skill. Supplementary `references/` and
`templates/` (moved from `skills/agent-browser/`) provide the full
command reference under `--full`.
- **`skills/agent-browser/SKILL.md`** — still the discovery stub that
`npx skills add` installs, now marked `hidden: true` so it stays out
of `skills list` inside the CLI. Body is a clean pointer to
`agent-browser skills get core` and the specialized skills.
The `hidden: true` frontmatter flag is a new, general mechanism: skills
marked hidden are omitted from `skills list` and `skills get --all` but
can still be fetched by explicit name. This keeps the stub reachable
for anyone who installed via `npx skills add` without polluting the
CLI-side skill listing.
## Behavior
```
$ agent-browser skills list
agentcore Run agent-browser on AWS Bedrock AgentCore cloud browsers...
core Core agent-browser usage guide. Read this before running...
dogfood Systematically explore and test a web application...
electron Automate Electron desktop apps (VS Code, Slack, Discord...)
slack Interact with Slack workspaces using browser automation...
vercel-sandbox Run agent-browser + Chrome inside Vercel Sandbox microVMs...
$ agent-browser skills get core # the actual usage guide
# ~420 lines of workflows, patterns, troubleshooting
$ agent-browser skills get agent-browser # still works if called explicitly
# the thin stub, now pointing at `core`
```
External `npx skills add vercel-labs/agent-browser` behavior is
unchanged: it finds and installs the thin `agent-browser` stub, which
tells the agent to run `agent-browser skills get core` for real
content. Version drift protection is preserved — the stub is the only
thing that gets copied; the real content is always runtime-fetched.
## Updated
- `cli/src/skills.rs` — `SkillInfo.hidden: bool`, parsed from
frontmatter; `run_list` and `run_get --all` filter it. 3 new unit
tests for the frontmatter parser.
- `cli/src/output.rs` — top-level `--help` and `skills` subcommand help
reference `skills get core` / `skills get core --full`.
- `AGENTS.md` — "update these files for user-facing features" now
points at `skill-data/core/` instead of the stub, with a note that
the stub is not the right place for feature content.
- `README.md`, `docs/src/app/skills/page.mdx` — describe the new
split and `skills get core --full` as the recommended entry point.
- `evals/cases/{command-usage,skill-selection}.ts` — expect
`skills get core` in agent output instead of `skills get
agent-browser`. Eval lib still reads `skills/agent-browser/SKILL.md`
(simulating what an agent sees after `npx skills add`).
All 11 skills unit tests pass. `cargo clippy -- -D warnings` and
`cargo fmt --check` clean. Verified end-to-end: `skills list` shows
`core` + specialized (no stub), `skills get core` returns the new
content, `skills get agent-browser` still returns the stub on explicit
request.
The `Skills:` section was buried between `Setup:` and `Snapshot Options:` in
the top-level `--help`, where an agent skimming the output would pass over it
on the way to flag docs. Move it to a prominent "Start here (for AI agents)"
block directly below `Usage:` so it's the first thing an agent sees, and
reframe the copy so it conveys what skills *are* (workflow patterns, ref
usage, copy-paste examples) rather than just listing subcommand flags.
Skills are the intended entry point for agents. They ship with the CLI,
always version-match the installed binary, and cover both `agent-browser`
core usage and specialized workflows (Electron, Slack, exploratory testing,
cloud browser providers). Surfacing them up front prevents agents from
guessing commands out of flag docs when a hand-written workflow guide is
one command away.
No functional change. Only the ordering and wording of `--help` output.
* fix(tabs): preserve refs across --tab peek and cover outer-tab-closed path
Follow-up to #1249 so `--tab <id>` is actually useful for agents:
- Save and restore the outer tab's `ref_map`, `iframe_sessions`, and
`active_frame_id` across a scoped command instead of clearing them.
`snapshot` → `--tab N <cmd>` → `click @e1` now keeps the outer tab's
refs intact. Scoped commands still see a clean slate so outer refs
can't resolve against the scoped tab's DOM.
- Close the coverage gap the Vercel review bot flagged on #1249: the
previous `e2e_tab_scoped_command_handles_outer_tab_closed` test used
`tab_close`, which is in the scoped-dispatch exclusion list, so it
never exercised the restore-skip branch it claimed to test. Renamed
to `e2e_tab_close_with_tab_id_closes_active_tab` with an honest
docstring, and added `e2e_tab_scoped_command_outer_tab_closed_mid_dispatch`
that actually hits the branch via `window.opener.close()` on a
script-opened intermediate tab.
- Add `e2e_tab_scoped_command_isolates_refs_from_outer_tab` pinning
that outer refs don't bleed into the scoped tab's DOM resolution.
- Rewrite `e2e_tab_scoped_command_clears_state_on_switch` as
`e2e_tab_scoped_command_preserves_outer_tab_state`, verifying the
restored @e1 still clicks end-to-end.
- Update the 52 `--help` entries for `--tab <id>` to describe peek /
restore semantics instead of a vague "Target specific tab ID".
- Update README, docs site, config schema, and the agent-facing
skills reference with working examples (refs survive the peek) and
a "when to use \`--tab <id>\` vs \`tab <id>\`" guide so agents pick
the right flag for their workflow.
* fix(tabs): use t<N> prefix for tab ids, add --label for named tabs
Follow-on to the tab work in #1249 and the prior commit, redesigning the
tab handle surface before release since nothing ships these features yet.
## Why
Incrementing integer tab ids (`1`, `2`, `3`) look indistinguishable from
positional indices in command output, LLM-generated scripts, and docs. In
the common single-agent case where position and id coincide, readers have
no visual cue for which mental model they're using. Positional indices
silently shift when unrelated tabs open/close, so misreading a handle as
an index is a correctness hazard.
## Changes
**Tab ids are now `t1`, `t2`, `t3` (strings).** Bare integer `tabId`
values are rejected with a teaching message rather than silently accepted.
The `t` prefix matches the `@e1` element-ref convention and makes ids
unmistakably non-positional at a glance.
**Labels.** Tabs can be created with a user-assigned label (e.g. `docs`,
`app`) via `tab new --label <name> [url]`. Labels are interchangeable
with `t<N>` ids everywhere a tab ref is accepted. They're never
auto-generated, never rewritten on navigation, and must be unique within
a session.
**Dashboard fix.** `packages/dashboard/src/types.ts` declared
`TabInfo.index: number` but the daemon has been sending `tabId` (not
`index`) since #892, making `tab.index` `undefined` and breaking the
dashboard's close/switch buttons silently. Updated the TS types and
usages to consume `tabId` (string) and optional `label`, restoring the
dashboard's tab interactions.
## Surface
- `cli/src/native/browser.rs`: `TabRef::parse` / `format_tab_id` /
`is_valid_label` / `PageInfo.label` / `BrowserManager::resolve_tab_ref`
/ `BrowserManager::has_label`. `tab_new` gains an optional label
argument with duplicate rejection. All JSON responses use the string
form and include the label.
- `cli/src/native/actions.rs`: scoped-command pre-dispatch and
`handle_tab_{switch,close,new}` parse string refs and resolve to
stable ids.
- `cli/src/{flags,commands,main,output}.rs`: `--tab` / config `tab`
are `String`; `tab` subcommand accepts `t<N>` or a label and supports
`tab new --label <name> [url]`. All 52 `--help` entries updated.
- `agent-browser.schema.json`: `tab` property type is now `string` with
a pattern matching `t<N>` or label form.
- `packages/dashboard`: `TabInfo.tabId: string` / `label?: string | null`;
`closeTabAtom`/`switchTabAtom` take `tabRef: string`; component props
updated.
- Docs: README, docs site (`commands/` and `configuration/`), and the
agent-facing skills reference rewritten with the new examples.
## Tests
- Added `TabRef::parse` / `format_tab_id` / `is_valid_label` unit tests
pinning the bare-integer rejection, the teaching error, label rules,
and round-tripping.
- Added `test_tab_switch_by_id` / `_by_label` / `test_tab_new_with_label`
/ `_with_label_and_url` / `_with_url_then_label` in `commands.rs`;
rewrote `test_tab_unknown_subcommand_errors` since labels make
`tab select` a legitimate ref.
- Added `e2e_tab_new_with_label_can_be_switched_and_peeked`,
`e2e_tab_new_with_duplicate_label_errors`,
`e2e_tab_scoped_command_rejects_bare_integer`.
- Migrated every existing tab e2e test (and one unit test) from
integer `tabId` to the string form.
`cargo fmt`, `cargo clippy -- -D warnings`, all 30 non-ignored tab unit
tests, all 13 tab e2e tests, and `tsc --noEmit` on the dashboard all
pass.
* refactor(tabs): drop --tab scoped peek flag; keep t<N> ids and labels
After fleshing out `--tab <id|label>` in the previous commits (scoped
pre/post-dispatch save/restore, ref preservation, outer-tab-closed edge
case, full e2e coverage), the machinery-to-value ratio makes the feature
hard to justify. Nixing it now while nothing has shipped.
## Why
- Every new daemon feature touching per-tab state has to reason about
scoped-dispatch interleaving. `ScopedRestore`, pre/post-dispatch hooks,
and the exclusion list add ongoing maintenance tax.
- Three separate PRs (#892, #1249, and this one pre-nix) were needed to
reach "works correctly." That's a smell.
- `tab <id|label>` switch + labels already cover the legible multi-tab
workflow case.
- `--tab` vs `tab <id>` have opposite lifecycle semantics but look
identical, teaching every agent two things where one would do.
- "Non-disruptive peek" isn't actually race-free: the daemon does swap
active tab during execution, so a concurrent client between pre- and
post-dispatch sees the scoped tab as active.
- Ref-based interaction with scoped tabs never worked ergonomically —
refs are per-tab, so `--tab N click @e1` requires `@e1` to already be
on tab N, which means a prior switch, which negates the peek.
- Adding a feature back is easy; removing shipped API is hard.
If per-tab caching (`HashMap<tab_id, RefMap>`) lands later, `--tab` can
be reintroduced essentially for free. That's the right time.
## Removed
- `--tab <id|label>` global flag (`cli/src/flags.rs`, `cli/src/main.rs`,
all 52 `--help` entries in `cli/src/output.rs`).
- `tab` property in `agent-browser.schema.json` and the config-options
row in `docs/src/app/configuration/page.mdx`.
- `ScopedRestore` struct, pre/post-dispatch save/restore in
`execute_command` (`cli/src/native/actions.rs`).
- `impl Default for RefMap` in `cli/src/native/element.rs` (only added
for `mem::take` in the scoped machinery).
- `e2e_tab_global_targeting`, `_snapshot`, `_snapshot_non_contiguous`,
`e2e_tab_scoped_command_preserves_outer_tab_state`,
`_isolates_refs_from_outer_tab`, `_restores_active_tab`,
`_outer_tab_closed_mid_dispatch`. 590 lines.
- The "When to use `--tab` vs `tab <id|label>`" sections in README,
docs site, and skills reference.
## Kept
- Stable tab ids (`t1`, `t2`, `t3`) with bare-integer rejection.
- User-assigned labels (`tab new --label docs [url]`), with duplicate
rejection and interchangeable use everywhere a tab ref is accepted.
- `BrowserManager::{active_tab_id, has_tab_id, resolve_tab_ref, has_label}`
accessors (still used by the remaining tab handlers).
- `TabRef::parse`, `format_tab_id`, `is_valid_label` and their unit
tests.
- Dashboard TS fix (`TabInfo.tabId` + `label`).
- `e2e_tab_close_with_tab_id_closes_active_tab` (renamed docstring to
drop the gone exclusion-list reference).
- `e2e_tab_new_with_label_can_be_switched_and_closed` (rewrite of the
previous `_and_peeked` test — now exercises only switch and close).
- `e2e_tab_switch_rejects_bare_integer` (rewrite targeting the
`tab_switch` daemon handler rather than the removed scoped path).
net: -900 lines across 12 files. `cargo fmt`, `cargo clippy -D warnings`,
all 25 non-ignored tab unit tests, all 6 tab e2e tests, and
`tsc --noEmit` on the dashboard all pass.
* fix(tabs): initialize tab_id on missing PageInfo sites
PR #892 added a required `tab_id: u32` field to `PageInfo` but missed two
initializer sites, which broke the build on the PR branch. CI never caught
this because the external-contributor workflow status was `action_required`
and never ran.
- `cli/src/native/browser.rs:395` — the `direct_page` branch of
`connect_cdp_inner` used by the cloud providers (Browserbase, Browserless,
Browser Use, Kernel, AgentCore). Use `assign_tab_id()` to get a fresh id.
- `cli/src/native/browser.rs:1580` — a unit test initializer. Use `tab_id: 1`
since the test doesn't exercise id assignment.
* feat(tabs): restore active tab and clear per-tab state for scoped --tab
Follow-up on PR #892's `--tab <id>` flag.
The original implementation called `tab_switch_by_id` directly from the
pre-dispatch block in `execute_command` but didn't touch the daemon's
per-tab state, and never restored the previously-active tab. Two concrete
issues this fixes:
1. `state.ref_map`, `state.iframe_sessions`, and `state.active_frame_id`
were left intact across the pre-dispatch switch, so `--tab N click @e1`
would try to resolve `@e1` against the scoped tab's DOM using a
backend-node id from the outer tab. In practice the click handler's
role+name fallback hid this as "element not found" errors, but on pages
where both tabs have similarly-labelled elements it could click the
wrong one.
2. The PR description promised scoped routing would "restore the previous
active tab", but the implementation permanently switched. `--tab 3
snapshot` would leave tab 3 as the active tab even after the command
returned, surprising subsequent non-scoped commands.
This change:
- Saves the current tab's stable `tab_id` (not its array index, which
would shift if the scoped command closed other tabs) before switching.
- Clears per-tab daemon state before the switch so refs/iframes/frame
context can't leak between tabs.
- After the action runs, restores the original active tab (also via
stable id) unless that tab was closed during the scoped command, in
which case we leave the scoped tab active.
- Adds `BrowserManager::active_tab_id()` and `has_tab_id()` accessors
to support the above without exposing the internal `pages` vector.
* test(tabs): regression tests for scoped --tab state clearing and restoration
Three new `#[ignore]` e2e tests pinning the fixed behavior:
- `e2e_tab_scoped_command_clears_state_on_switch` — populates `ref_map` on
tab 1, runs a `tabId: 2`-scoped command, asserts `ref_map`,
`iframe_sessions`, and `active_frame_id` are all cleared.
- `e2e_tab_scoped_command_restores_active_tab` — sets up two tabs, runs
a scoped command against the non-active one, asserts a subsequent
unscoped command reflects the originally-active tab.
- `e2e_tab_scoped_command_handles_outer_tab_closed` — runs a scoped
`tab_close` that kills the outer tab itself, asserts no error and the
scoped tab becomes active.
Also updates two misleading comments in the PR's existing
`e2e_tab_global_targeting*` tests to reflect restoration semantics; the
assertions themselves were already consistent with restoration.
* docs(tabs): document stable tab IDs and --tab scoped-command flag
Per AGENTS.md, changes that users or agents would need to know about must
land in every doc surface. Fills the gaps PR #892 left:
- `README.md` — new `--tab <id>` row in the Options table, rewrite the
tab command examples to use `<id>` instead of `<n>`, add a paragraph
explaining stable tab IDs and `--tab` peek semantics.
- `docs/src/app/commands/page.mdx` — same command-example rewrite plus a
new "Stable tab IDs and `--tab`" subsection.
- `docs/src/app/configuration/page.mdx` — add `tab` row to the config
options table so JSON config users can discover it.
- `agent-browser.schema.json` — add `tab` property with description,
matching the config schema.
- `skills/agent-browser/references/commands.md` — same command-example
rewrite plus a short paragraph for agents on when to use `--tab`.
Introduces stable per-tab IDs and a global `--tab <id>` flag for scoping individual commands to a specific tab.
Breaking change: response payloads for `tab_list`, `tab_new`, `tab_switch`, `tab_close`, and `window_new` now use `tabId` instead of `index`. `tab_close` returns `{tabId, closed: true}` instead of `{closed, activeIndex}`. `agent-browser tab <unknown>` now errors instead of silently listing tabs.
Follow-up PR to land immediately after this fixes a compile error on the provider direct-page path, clears per-tab daemon state around scoped switches, and implements active-tab restoration so `--tab N` is non-intrusive as intended.
Fix idleTimeout description to document human-friendly formats (30s,
5m, 1h) alongside raw milliseconds. Add trailing newline. Serve the
schema from the docs app at agent-browser.dev/schema.json via a
prebuild copy step, and update all $schema URLs to use the stable
docs-hosted URL instead of raw GitHub.
* feat: add JSON Schema for agent-browser config files
Adds agent-browser.schema.json describing all config options with
types and descriptions. Enables IDE autocomplete and validation when
referenced via $schema in agent-browser.json or
~/.agent-browser/config.json.
README and docs site updated to document the schema reference.
* fix(schema): use integer type for maxOutput to match usize deserialization

* fix: load storage state at launch when --state / AGENT_BROWSER_STATE is set
The `--state` flag and `AGENT_BROWSER_STATE` env var were documented as
restoring saved browser state (cookies + localStorage) at launch, but
`load_state()` was never called after the browser started. The feature
has been broken since it was introduced.
Adds `try_load_storage_state()` and calls it from every early-return
path in `auto_launch()` (lazy launch triggered by commands like
`navigate`) and from `handle_launch()` (explicit `launch` command).
Also adds 4 e2e tests covering all state-persistence paths:
- Explicit launch with `storageState` field
- Auto-launch via `AGENT_BROWSER_STATE` env var
- Session-name auto-restore via `try_auto_restore_state`
- Explicit `state_load` command (baseline sanity check)
Fixes#1164.
* style: apply cargo fmt to e2e_tests.rs
Reformats a single long format\! call to satisfy CI's rustfmt check.
No behavior change.
* fix: call try_load_storage_state in all handle_launch branches
The CDP URL, CDP port, auto-connect, and provider early-return branches
were skipping storage state loading because try_load_storage_state was
only called in the normal BrowserManager::launch() path at the bottom
of handle_launch().
Also compute storage_state_owned once and reuse it across all branches
rather than borrowing storage_state (a &str tied to cmd) in a helper
that needs an owned Option<String>.
* Fix storage state reload on reused launches
* Fix storage-state launch errors
* Fix storage state replay ordering
* Align storage-state errors across launch paths
* Fix storageState launch cleanup
* fix(test): tolerate stale screencast frames in viewport e2e test
Chrome's `Page.startScreencast` `maxWidth`/`maxHeight` are upper bounds,
and early frames can arrive before the viewport resize fully takes effect.
Instead of asserting exact JPEG dimensions on the first frame, skip frames
with stale dimensions and wait for one that matches.
* Prepare v0.25.5
Chrome's `Page.startScreencast` `maxWidth`/`maxHeight` are upper bounds,
and early frames can arrive before the viewport resize fully takes effect.
Instead of asserting exact JPEG dimensions on the first frame, skip frames
with stale dimensions and wait for one that matches.
The `e2e_recording_inherits_viewport` test added in #1208 requires
ffmpeg on the CI runner. Without it, `recording_start` fails with
"ffmpeg not found".
* fix: prefer DevToolsActivePort websocket path over HTTP discovery in --auto-connect
Reverses the discovery order in `auto_connect_cdp()` so the exact
WebSocket path from DevToolsActivePort is tried first, falling back
to legacy HTTP endpoints (`/json/version`, `/json/list`) only when
the direct path fails. This eliminates the duplicate remote-debugging
permission prompts caused by unnecessary HTTP probes on Chrome M144+.
Also adds `verify_ws_endpoint()` to validate the WebSocket URL is a
live CDP server before returning it, preventing stale URLs from being
handed to callers.

* fix: inherit viewport dimensions in recording context
When `record start` creates a new browser context, it now re-applies the
current viewport settings (from `set viewport` or `set device`) so the
recording resolution matches what the user configured instead of falling
back to the default 1280×720.

The text-mode output formatter had branches for most `get` subcommand
response shapes but was missing handlers for `boundingbox` and `styles`.
Both commands fell through to the default "Done" message instead of
printing the returned data.
Closes#1231
Adjust tab-removal bookkeeping so closing or losing a page before the active tab keeps the session pointed at the same logical page instead of silently shifting to the next one.
Add regression coverage for earlier-tab removal, later-tab removal, last-tab clamping, and the empty-page case.

The skills CLI metadata.internal flag was never implemented (PRs #587
and #652 were both closed). All 6 skills were showing in the installer.
Move the 5 specialized skills (dogfood, electron, slack, vercel-sandbox,
agentcore) from skills/ to skill-data/, which the skills CLI does not
search. The bootstrap skill stays in skills/ for discovery. The Rust CLI
searches both directories so agent-browser skills list/get still serves
all 6.
