- Restore the `refs` dictionary in `--json` snapshot output, matching the documented API contract
- The `refs` field was silently dropped during the Node.js to Rust rewrite (v0.20), causing consumers parsing `data.refs` for programmatic element interaction to receive no structured ref data
Fixes#785
* fix: use VP9 codec for webm recording output
The recording command hardcoded libx264 (H.264) which is incompatible
with the WebM container format. WebM only supports VP8/VP9/AV1 codecs,
causing ffmpeg to fail when users specify a .webm output file.
Select codec based on output file extension: libvpx-vp9 for .webm,
libx264 for other formats.

* refactor: use CRF mode for VP9 webm encoding
Switch from bitrate target (-b:v 2M) to constant quality mode (-crf 30),
which is the standard approach for screen recording (used by Puppeteer
and recommended by ffmpeg VP9 guide). CRF adapts bitrate to scene
complexity for more consistent quality.

* fix: add -b:v 0 for true constant quality VP9 encoding
Without -b:v 0, libvpx-vp9 uses its default bitrate target alongside
-crf, resulting in constrained quality mode instead of true constant
quality mode.

* fix: pad video dimensions to even numbers for h264 compatibility
libx264 requires width and height to be divisible by 2, but CDP
screencast can capture frames with odd dimensions (e.g. 1280x577).
Add pad filter to ensure even dimensions for all codecs.

The comment said "Ignore SIGPIPE" but the code actually resets SIGPIPE
to SIG_DFL (default behavior = process termination), not SIG_IGN (ignore).
Updated the comment to accurately describe what the code does and why.

Regenerate pnpm-lock.yaml to match the cleaned-up package.json (only
@changesets/cli remains). Add CI environment detection to
should_disable_sandbox() so Chrome launches with --no-sandbox on GitHub
Actions runners where AppArmor blocks unprivileged user namespaces.
The test was reading AGENT_BROWSER_HEADED without holding ENV_MUTEX,
causing a race with test_launch_options_from_env_headed_flag when
tests run in parallel.
Three issues prevented --engine lightpanda from working with official
Lightpanda release builds:
1. Missing --log_level info: Lightpanda release builds default to
log_level=warn, which suppresses the info-level "server running"
startup message. wait_for_address() blocks forever reading an empty
stderr pipe. Pass --log_level info explicitly.
2. --timeout 0 means instant disconnect: Lightpanda interprets 0 as
"timeout after 0ms", not "no timeout". Use 604800 (1 week, the
documented maximum) instead.
3. extract_address only matched pretty format: Release builds use
logfmt (address=HOST:PORT without spaces), but the parser only
matched the pretty format (address = HOST:PORT with spaces). Handle
both formats.
* fix: narrow "not found" pattern in to_ai_friendly_error to avoid catching
non-element errors
Change `contains("not found")` to `contains("element not found")` so that
connection/state errors like "Browser not found" pass through unchanged
instead of being incorrectly mapped to "Element not found" message.
* remove comment
* fmt
* test: use real project error message in non-element not found test
When user explicitly sets --headed false, the CLI was ignoring this
flag because the launch condition only checked if flags.headed was
true. This meant that --headed false would not trigger a launch
command, and subsequent commands would auto-launch with default
headless=true.
The fix adds a cli_headed flag to track when the user explicitly
sets --headed (regardless of value), and includes this in the
launch condition check.
Fixes#743
This PR fixes CI build failures by addressing code formatting and linting issues that were causing the builds to fail.
**Changes made:**
1. **Rust formatting fixes in `cli/src/commands.rs`:**
- Removed unnecessary multi-line formatting for clipboard operations
- Applied consistent single-line formatting for return statements
- Fixed line length and formatting for the `test_wait_text_with_timeout` test function
2. **TypeScript fixes in `src/actions.ts`:**
- Fixed `waitForFunction` usage in the `handleWait` function by replacing the function parameter approach with a string-based implementation
- Properly escaped the text parameter using `JSON.stringify` to prevent potential injection issues
These changes ensure the code passes linting checks (clippy for Rust, ESLint for TypeScript) and formatting validation (rustfmt, prettier) that are enforced in the CI pipeline.
Fixes#751
* feat: add screenshot output config, clipboard CLI commands, and fix wait --text native path
## Summary
- Add `--screenshot-dir`, `--screenshot-quality`, and `--screenshot-format` CLI flags (with corresponding `AGENT_BROWSER_SCREENSHOT_DIR`, `AGENT_BROWSER_SCREENSHOT_QUALITY`, `AGENT_BROWSER_SCREENSHOT_FORMAT` env vars) so users can configure where and how screenshots are saved without specifying a full path every time
- Add `clipboard read`, `clipboard write <text>`, `clipboard copy`, and `clipboard paste` CLI commands, exposing the existing protocol-level clipboard handlers that were previously only accessible via JSON-RPC
- Fix `wait --text` in native mode: the CLI was emitting `selector: "text=..."` (a Playwright-style locator) which native's `querySelector` can't handle. Now emits a `text` field that correctly hits the native `wait_for_text` polling path
- Add native clipboard `copy` and `paste` support via CDP `Input.dispatchKeyEvent`, and a `write` operation to the Node.js handler
* fix: resolve CI failures in Rust formatting and TypeScript typecheck
Use string-based page.evaluate for clipboard writeText to avoid
referencing `navigator` in Node.js compilation context. Run cargo fmt
to fix formatting in commands.rs and screenshot.rs.
* fix: clipboard write captures full multi-word text
Use rest[1..].join(" ") instead of rest.get(1) so unquoted multi-word
input like `clipboard write hello world` sends the full string rather
than silently dropping everything after the first word.

Fix issue where Chrome extensions specified in the `extensions` field of `config.json` were not being loaded when launching the browser.
## Problem
Extensions configured via the `extensions` field in `config.json` were not being passed to the Chrome browser launch command, causing them to be ignored.
## Changes
- Added `!flags.extensions.is_empty()` to the launch trigger condition to ensure browser launch is triggered when extensions are configured
- Added extensions to the launch command JSON payload so they are properly passed to the browser
Fixes#726
* feat: add browserless provider integration to native browser implementation
This PR adds support for the Browserless provider to the native browser implementation, expanding the available remote browser providers from 3 to 4.
## Changes Made
- **Added `connect_browserless()` function**: Implements session creation with Browserless API using environment variables for configuration
- **Updated provider routing**: Added "browserless" case to the main provider switch statement
- **Added session cleanup**: Implemented proper session termination using the stop URL returned by Browserless
- **Updated documentation**: Modified comments and error messages to include Browserless in the supported provider list
- **Environment variable support**: Added support for configurable Browserless settings including API key, URL, browser type, TTL, and stealth mode
## Implementation Details
- Uses standard Browserless session API with POST to create sessions and DELETE to terminate
- Supports both chromium and chrome browser types with validation
- Includes proper error handling for API failures and missing configuration
- Stores the stop URL as session_id for cleanup purposes
- Follows the existing provider pattern for consistency
Fixes#744
* fix: URL-encode API key in browserless session request
Use reqwest's .query() method instead of string-formatting the token
directly into the URL, matching the Node.js implementation's use of
encodeURIComponent. Prevents malformed URLs if the API key contains
special characters.

The client (connection.rs) and native daemon (native/daemon.rs) used
different get_port_for_session() implementations on Windows:
- Client: i32, .chars(), djb2 — (hash << 5) - hash + c
- Daemon: i64, .bytes(), Java hashCode — hash * 31 + b
For session name "default", client computes port 50838 while the
daemon binds on 51174, causing a 5-second timeout and startup failure.
Fix: align native/daemon.rs to use the identical djb2 algorithm from
connection.rs (i32, chars, djb2), so both sides agree on the port.
Unix is unaffected (uses Unix domain sockets, no port hashing).
Tests: add port hash regression tests to all three implementations
(native/daemon.rs, connection.rs, daemon.ts) to prevent future drift.
Fixes#705
* Remove BROWSERBASE_PROJECT_ID requirement
The Browserbase API no longer requires a project ID to create sessions —
it is inferred from the API key. Remove the env var requirement from both
the TypeScript daemon and Rust CLI, and update docs accordingly.
* Remove unnecessary Content-Type header since no body is sent
Browserbase has no DELETE endpoint for sessions. The correct API is
POST /v1/sessions/:id with body { status: "REQUEST_RELEASE" }. The old
DELETE call returned an error that was silently swallowed, causing every
session to leak until the 30-min idle timeout.
Fixed in both Node.js (src/browser.ts) and native Rust
(cli/src/native/providers.rs) paths.

* Make KERNEL_API_KEY optional for external credential injection
When running inside environments with external credential injection
(e.g. Vercel Sandbox credentials brokering), the KERNEL_API_KEY env
var can be omitted. The network layer injects the Authorization header
on outbound requests to api.onkernel.com, so the API key never needs
to exist inside the sandbox.
If KERNEL_API_KEY is set, it's used as before. If not, requests are
sent without an Authorization header, allowing external injection.
Without either, the Kernel API returns 401.

* Make KERNEL_API_KEY optional in native Rust daemon too
Applies the same change to the native Rust connect_kernel() function
so both the Node.js and native code paths support external credential
injection.
Made-with: Cursor
* Address review feedback: fix type errors, cargo fmt, always send cleanup DELETE
- Fix kernelApiKey assignment: use ?? null for undefined -> null
- Fix closeKernelSession signature: accept string | undefined
- Always send DELETE on cleanup even without local API key (external
injection covers it)
- Run cargo fmt on Rust code
Made-with: Cursor

TypeScript CI has prettier --check but Rust CI only runs cargo test.
Add cargo fmt --check to catch formatting issues early, and fix the
8 pre-existing formatting violations on main.
reqwest_get_string() was hand-rolling HTTP/1.1 over raw TCP despite reqwest
being an existing dependency. The hand-rolled implementation had two bugs:
1. URL path parsing: url.find('/') matched the first '/' in 'http://',
producing path '//127.0.0.1:9222/json/version' instead of '/json/version'
2. read_to_end() hangs: Chrome's DevTools HTTP server ignores Connection: close
and keeps the socket open, so read_to_end() waits for EOF that never comes
This caused 'agent-browser --cdp <port>' to always timeout when AGENT_BROWSER_NATIVE=1.
Fix: replace 49 lines of broken TCP code with reqwest::get(), which was
already in Cargo.toml.
When the daemon process crashes during startup (e.g., missing
Playwright), stderr was discarded via Stdio::null(), so users only
saw "Daemon failed to start (port: ...)" with no diagnostic info.
Now captures daemon stderr via Stdio::piped() and detects early process
exit with try_wait() during the startup polling loop. If the daemon
crashes, the actual error from stderr is shown to the user.
Also forwards --debug flag to the daemon process as AGENT_BROWSER_DEBUG
so debug logging works end-to-end.
Closes#56
* fix: suppress spurious --native warning when set via env var
When AGENT_BROWSER_NATIVE=1 is set via environment variable, every
command after the first would warn:
⚠ --native ignored: daemon already running.
This is a false positive — the daemon was already spawned in native
mode and inherited the env var. The warning should only fire when
--native is explicitly passed on the CLI to an already-running daemon.
Add cli_native flag (consistent with existing cli_* pattern) to
distinguish CLI origin from env var origin.
* fix: add flag to test cfg
* fix: cli_native should track flag presence, not value
--native false on CLI should still warn when daemon is already
running, since the user is explicitly trying to change the mode.
