* fix: prevent system package removal during Ubuntu dependency install
This PR fixes a critical issue where installing agent-browser dependencies on Ubuntu 24.04+ could trigger removal of hundreds of system packages due to library naming conflicts during the 64-bit time_t transition.
**Problem:**
On Ubuntu 24.04+, many core libraries were renamed with a "t64" suffix as part of the 64-bit time_t transition. The installer was trying to install old library names, causing apt to propose removing 400+ essential system packages to resolve conflicts.
**Changes:**
- Added comprehensive t64 variant detection for all apt dependencies
- Implemented pre-install simulation check to detect potential package removals
- Added safety abort mechanism when removals are detected (>0 packages)
- Enhanced error messaging to explain the issue and provide manual installation guidance
- Improved logging and user feedback during the installation process
**Implementation Details:**
- Uses `apt-get install --simulate` to safely check for conflicts before proceeding
- Checks for t64 variants first, falls back to original names if t64 versions don't exist
- Provides detailed output showing which packages would be removed
- Maintains compatibility with older Ubuntu versions that don't have t64 packages

* Add iframe support for CLI interactions and snapshots
This PR adds comprehensive iframe support to the agent browser CLI, allowing users to interact with elements inside iframes seamlessly.
## Problem
Users couldn't interact with elements inside iframes via the command line. The existing `frame` command was non-functional as it set `active_frame_id` but no other code read this value.
## Changes Made
### Enhanced Frame Context Tracking
- Added `frame_id` field to `RefEntry` to track which frame each element reference belongs to
- Updated `RefMap::add` and related methods to accept and store frame context
- Modified element resolution functions to use frame context from ref entries
### Improved Frame Command
- Fixed the existing `frame` command to actually work by threading `active_frame_id` through snapshot operations
- Added support for iframe element references (e.g., `frame @e2`) in addition to CSS selectors
- Enhanced frame detection to work with both named frames and iframe elements
### Updated Snapshot Behavior
- Modified `take_snapshot` to accept optional frame context parameter
- Updated all snapshot call sites to pass appropriate frame context
- Maintained backward compatibility while enabling frame-scoped operations
### Element Resolution Updates
- Updated `resolve_element_center` and `resolve_element_object_id` to use frame context from ref entries
- Modified `find_node_id_by_role_name` to support frame-specific element lookup
- Ensured all interaction functions work correctly within iframe contexts
## Implementation Details
- Frame context is now properly propagated through the entire element interaction pipeline
- The `frame` command can accept both CSS selectors and element references
- All existing functionality remains intact while adding iframe capabilities
- Added `Iframe` to interactive roles for better element discovery
Fixes#863
* docs: add iframe support documentation
Document the new iframe capabilities across all documentation surfaces:
- Auto-inlining of iframe content in snapshots
- Direct interaction with iframe element refs
- frame command support for element refs (@e3)
- Scoped snapshots via frame switching
* fix: pass active frame context to diff snapshots and fix nameless iframe lookup
- handle_diff_snapshot now respects active_frame_id instead of always
passing None, so diff snapshots work correctly inside iframes
- Nameless/id-less iframes now fall back to src URL (or null) instead of
the literal string 'frame' which never matched any frame in the tree
* fix: resolve iframe frame ID via DOM.describeNode and reduce code duplication
- handle_frame: Use DOM.describeNode + contentDocument.frameId to resolve
iframe frame IDs directly, fixing failures for nameless iframes that
lack name/id/src attributes
- element.rs: Deduplicate add() by delegating to add_with_frame()
- snapshot.rs: Guard against out-of-bounds insert_str when iframe marker
is on the last line without a trailing newline

* refactor: make --full/-f a command-level flag instead of global
Move --full/-f from global flags (parsed in flags.rs) to command-level
parsing in commands.rs, scoped to the three commands that actually use
it: `screenshot`, `diff screenshot`, and `diff url`.
This frees up `-f` for other commands (e.g. `--follow` on
`console`/`errors`, see #867) and better reflects that full-page
capture is not a global concern.
Changes:
- Remove `full` from Flags struct, Config struct, and global flag parsing
- Remove `--full`/`-f` from clean_args global boolean flags list
- Parse `--full`/`-f` inline in `screenshot` command handler
- Accept `-f` shorthand in `diff screenshot` and `diff url` (previously
only `--full` was accepted at command level)
- Remove fallback from global `flags.full` in diff subcommands
- Update tests to pass --full as a command argument rather than a global flag
Fixes#876
* fix: remove stale AGENT_BROWSER_FULL env var from help and add -f shorthand tests
- Remove AGENT_BROWSER_FULL from help text in output.rs since the env
var is no longer read after moving --full to command-level parsing
- Add test_screenshot_full_page_shorthand to verify screenshot -f works
- Add test_diff_screenshot_command_full_flag_shorthand to verify
diff screenshot -f works

Expose HAR recording as a CLI subcommand under the existing `network`
command so users can capture and export network traffic without a
separate tool or opening the browser twice.
- Parse `network har start` and `network har stop [path]` in commands.rs
- Enrich HarEntry with request/response headers, timestamps, status text,
resource type, HTTP version, and body sizes from CDP events
- Produce HAR 1.2 output with creator/browser metadata, query strings,
and proper header arrays compatible with Chrome DevTools HAR viewer
- Auto-generate output path under ~/.agent-browser/tmp/har/ when omitted
- Add har_stop to skip_launch list so export works without a live browser
- Update help text, README, docs site, SKILL.md, and security policy docs
- Add unit tests for parsing, HAR entry serialization, and stop behavior

* fix: fall back to /json/list when /json/version is unavailable
Chrome's UI-based remote debugging mode (the permission dialog flow)

* fix: Windows auto-connect profiling (#835)
Fix three interrelated bugs causing `--auto-connect` to fail on Windows,
plus a UX issue where auto-connect hijacked existing tabs:
1. Stale DevToolsActivePort — add TCP port liveness check before returning
M144+ WebSocket URL; remove stale files when port is dead.
2. Missing Windows error codes — add os error 10061 (WSAECONNREFUSED) and
10054 (WSAECONNRESET) to is_transient_error() so daemon startup races
are retried on Windows.
3. --auto-connect not propagated to daemon — add auto_connect to
DaemonOptions, set AGENT_BROWSER_AUTO_CONNECT env var via
apply_daemon_env(), and guard the headed launch block so it doesn't
send a second launch that overrides the auto-connect.
4. Auto-connect opens a fresh tab — after connecting to an existing
Chrome, create a new about:blank tab and bring it to front so
navigations don't hijack the user's existing tabs.
Made-with: Cursor
* fix: address review feedback — cargo fmt, shared helper, Windows tests
- Run cargo fmt on is_port_reachable() formatting
- Extract duplicated auto-connect-with-fresh-tab logic into
connect_auto_with_fresh_tab() helper used by both handle_launch()
and auto_launch()
- Add unit tests for Windows WSAECONNREFUSED (os error 10061) and
WSAECONNRESET (os error 10054) in is_transient_error()

* fix: propagate --cdp flag to daemon via AGENT_BROWSER_CDP env var
The --cdp flag was not being passed to the daemon process as an environment
variable, causing auto-reconnection to fail. The daemon's auto_launch()
function checks for AGENT_BROWSER_CDP, but this was never set when spawning
the daemon.
This commit adds:
- cdp field to DaemonOptions struct
- AGENT_BROWSER_CDP env var setting in apply_daemon_env()
- flags.cdp propagation in main.rs
This ensures reliable CDP connection recovery when using --cdp with external
browsers like Lightpanda, Electron apps, or remote Chrome instances.
Fixes reconnection issues with --cdp flag after connection drops.

`discover_cdp_url` now accepts a host parameter instead of hardcoding
127.0.0.1, allowing `connect "http://<remote-ip>:<port>"` to query the

The `wait --load networkidle` command was incorrectly returning immediately when pages were served from cache, causing subsequent commands to fail. This happened because the network idle logic would return instantly when no network requests were pending, without observing any idle period.
## Changes Made
- Extract network idle polling logic into a separate `poll_network_idle` function for better testability
- Fix the timeout handling to start a 500ms idle timer when no requests are pending, instead of returning immediately
- Add comprehensive unit tests covering the regression case and normal network request flows
- Ensure the function always observes at least 500ms of network inactivity before resolving, even for cached pages
## Key Fix
The critical change is in the timeout branch: when no CDP events arrive within 600ms, we now start the idle timer if no requests are pending, rather than returning `Ok(())` immediately. This prevents false-positive idle detection for pages that load entirely from cache.
Fixes#846
* fix: resolve snapshot -C and screenshot --annotate hang over WSS (#841)
Root cause: sequential CDP round-trips per element in
find_cursor_interactive_elements() and collect_annotations() caused
timeouts over high-latency WSS connections (~200ms × 200+ elements
exceeds the 30s CDP timeout).
Fix:
- snapshot -C: Replace per-element CDP calls with a single JS eval
that detects cursor:pointer/onclick/tabindex elements in-browser,
then batch-resolve via DOM.querySelectorAll + concurrent
DOM.describeNode calls using join_all
- screenshot --annotate: Replace sequential DOM.resolveNode +
getRect calls with concurrent join_all, matching v0.19.0's
Promise.all() pattern
Behavioral parity with v0.19.0 (Node.js/Playwright):
- cursor:pointer detection via getComputedStyle
- Inherited cursor:pointer dedup (skip children of pointer parents)
- interactiveTags and interactive ARIA roles exclusion
- Role differentiation: clickable vs focusable
- Text dedup against ARIA tree ref names and quoted strings
- Edge case: -i -C shows cursor elements even when ARIA tree is empty
Tests:
- 5 unit tests for build_dedup_set() helper
- 3 e2e regression tests: cursor-interactive detection, annotation
scaling to 50 elements, cursor scaling to 100 elements
* fix: add hidden/aria-hidden filtering, contentEditable support, and cleanup robustness
- Restore hidden/aria-hidden element filtering in cursor-interactive JS
(was present in old code, dropped during rewrite)
- Add contentEditable detection with 'editable' role and hint
- Replace fire-and-forget cleanup with warning on failure
- Simplify build_dedup_set to use ref_map only (eliminates fragile
tree-text quote parsing; ref_map already has all ref-bearing names)

* fix: use correct Windows virtual-key codes for punctuation in type command
The `type` command was dropping punctuation characters like `.`, `'`, and
`#` because `char_to_key_info()` used raw ASCII codes as the
`windowsVirtualKeyCode` in CDP `Input.dispatchKeyEvent` calls. For
punctuation the ASCII value collides with unrelated VK codes — most
critically '.' (ASCII 46) equals VK_DELETE (0x2E), causing Chrome to
interpret periods as Delete key presses.
Changes:
- Add `punctuation_key_info()` with correct VK_OEM_* codes matching
Playwright's USKeyboardLayout (e.g. Period=190, Slash=191, Semicolon=186)
- Fall back to `Input.insertText` for characters without a US keyboard
mapping (emoji, CJK, etc.), matching Playwright's `keyboard.type()`
- Update e2e test to use `type` instead of `fill` workaround for email
- Add unit tests verifying VK code parity with Playwright's layout

The v0.20.0 migration from Playwright to the native Rust daemon introduced
two regressions in checkbox/radio handling:
1. `is_element_checked` only read `this.checked`, which is undefined on
non-input elements. Material Design and ARIA controls use wrapper divs
with `role="checkbox"` and `aria-checked`, or hide the native input
off-screen inside a label. The function now mirrors Playwright's
`getChecked()` with follow-label retargeting: native `.checked`,
`aria-checked` for ARIA roles, `label.control` traversal, and nested
input lookup.
2. `check`/`uncheck` accepted the coordinate-based CDP click result
without verifying the state actually changed. When the AX tree's
`backendDOMNodeId` points to a hidden off-screen input (common in
Material Design), `Input.dispatchMouseEvent` hits nothing. The actions
now re-check state after clicking and fall back to a JS `.click()` on
the resolved input — matching Playwright's `_setChecked` verify step.
Adds e2e regression test covering Material Design (hidden input + ripple
overlay), ARIA-only, and native checkbox patterns.

When using --auto-connect, discover_and_attach_targets() was selecting
Chrome internal pages (chrome://, chrome-extension://, devtools://) as
the active target. Follow-up commands like `get url` and `snapshot`
would then return data from targets like chrome://omnibox-popup.top-chrome/
instead of the actual application tab.
Add is_internal_chrome_target() filter to exclude internal Chrome targets
from the discovery results. If no user-facing targets remain after
filtering, the existing "create a new tab" fallback handles it.

* fix: restore WebSocket streaming in native daemon
The v0.20.0 Rust rewrite broke WebSocket streaming — connections opened
but received zero messages before closing. Multiple issues contributed:
1. StreamServer was dropped immediately after creation in daemon.rs,
closing the broadcast channel and killing all WS connections.
2. Screencast frames were only processed during command polling
(drain_cdp_events) instead of in real-time, unlike the 0.19.0
TypeScript cdp.on('Page.screencastFrame') callback.
3. Auto-start/stop screencast on WS client connect/disconnect was
missing from the Rust implementation.
4. Screencast CDP commands used the wrong session ID (daemon session
name instead of the CDP page session from Target.attachToTarget).
5. Broadcast channel Lagged errors killed WS connections instead of
being handled gracefully.
The fix adds a background CDP event loop in StreamServer that subscribes
to Chrome events and broadcasts screencast frames in real-time, properly
tracks the CDP page session ID, restores auto-screencast lifecycle, and
keeps the StreamServer alive in DaemonState.
Fixes#820
* fix: use actual CDP session ID for input dispatch in stream WebSocket
Pass the real cdp_session_id (from Target.attachToTarget) through to
handle_ws_client instead of an empty string. Previously, input commands
(mouse, keyboard, touch) were sent with `"sessionId": ""` which Chrome
silently rejects. Now the correct page session ID is read at dispatch
time, and when no session ID is set yet (before browser launch),
the field is omitted entirely via `None` so Chrome uses browser-level
dispatch.

* fix: snapshot --selector scopes to the matched element subtree
The native Rust daemon accepted the --selector flag but never used it —
the full accessibility tree was always returned regardless of the
selector. This restores the 0.19.0 behaviour where snapshot --selector
returns only the subtree rooted at the matched CSS selector.
The implementation resolves the selector via Runtime.evaluate, fetches
the full DOM subtree with DOM.describeNode(depth: -1) to collect all
descendant backendNodeIds, then filters the AX tree to render only the
nodes whose backendDOMNodeId falls within that set. This correctly
handles elements like <body> that don't map to a direct AX node.
Also fixes handle_snapshot reading "depth" instead of "maxDepth" from
the command JSON, which caused --depth to be silently ignored.

* fix: add appium: vendor prefix to iOS capabilities for Appium v3
Appium v3 enforces the W3C WebDriver spec strictly, requiring
non-standard capabilities to use vendor prefixes. The iOS provider
was sending capabilities like `automationName`, `noReset`, `deviceName`,
`platformVersion`, and `udid` without the required `appium:` prefix,
causing session creation to fail with InvalidArgumentError.
This change prefixes all non-standard capabilities with `appium:` while
leaving standard W3C capabilities (`platformName`, `browserName`)
unprefixed. Backwards-compatible with Appium v2, which accepts both
formats.

* fix: replace screenshot polling with screencast-based piped ffmpeg recording
Recording previously used Page.captureScreenshot polling at 10fps,
which was CPU-heavy and produced inconsistent results. Now uses
Page.startScreencast with throttled acks (35ms interval) to receive
frames event-driven from Chrome, and pipes JPEG data directly to
ffmpeg stdin in real-time instead of saving temp files.
- Spawn ffmpeg at recording start with piped stdin (image2pipe)
- Background task receives screencast frames, interpolates gaps by
repeating the last frame based on timestamps, targets 25fps
- Ack throttling controls Chrome's frame push rate
- Fix: current frame was never written after the first one
- Fix: frame count was read before task finished padding
- Remove tokio-util dependency (replaced CancellationToken with oneshot)
- Add tokio "process" feature for async child process stdin pipe
- Extract start/stop_recording_task helpers on DaemonState
- Add tests for restart, ffmpeg codec selection, and stop without task

* fix: add kill_on_drop to ffmpeg process to prevent zombie on task panic

Screencast only pushes frames on visual changes, producing short videos

regardless of page activity, guaranteeing duration matches wall-clock time.

* Improve postinstall message to detect existing Chrome installations
Previously, the npm postinstall script always recommended running `agent-browser install` to download Chrome for Testing, even when users already had a working Chrome installation on their system.
This change adds Chrome detection logic to the postinstall script that mirrors the runtime behavior:
- Checks for system Chrome installations on macOS, Linux, and Windows
- Shows a success message when Chrome is found, indicating it will be used automatically
- Only shows the `agent-browser install` warning when no Chrome is detected
- Provides platform-specific guidance (Linux `--with-deps` flag, `--executable-path` alternative)
The detection logic matches the existing Rust `find_chrome()` implementation to ensure consistency between postinstall messaging and runtime behavior.

* fix: gracefully fall back to role/name lookup when backend_node_id is stale
When the DOM changes between snapshot and click (common with SPAs and
dynamic UIs), the stored backend_node_id becomes invalid. Previously,
DOM.getBoxModel and DOM.resolveNode failures propagated as hard errors,
bypassing the role/name fallback path entirely. Now these failures are
caught and the code falls through to a JS-based element lookup.
Also adds resolve_object_id_by_role_name so that resolve_element_object_id
has a fallback for ref-based lookups (previously it had none), and
improves the role matching JS to correctly map implicit ARIA roles
(e.g. <input type="submit"> → "button", <a href> → "link").
Closes#805
* test: add e2e regression test for stale ref click fallback (#805)
Verifies that clicking a ref whose backend_node_id has become stale
(because the DOM was replaced by JavaScript) falls back to role/name
lookup instead of failing with "Could not compute box model".
* fix: use accessibility tree for stale ref fallback instead of JS heuristic
Replace the hand-rolled JS role/name matching (getImplicitRole,
getAccessibleName) with a re-query of Accessibility.getFullAXTree —
the same data source that built the ref map during snapshot. This
guarantees role/name matching is identical to what was stored,
preventing silent wrong-element clicks from name computation
divergence (e.g. aria-labelledby, <label for>, alt text).
Matches v0.19.0 (Playwright) behavior where getByRole always
re-queried the live accessibility tree.
