Adds `keyboard type` and `keyboard insertText` subcommands that
operate on the currently focused element without requiring a selector.
Essential for contenteditable editors (Lexical, ProseMirror, CodeMirror,
Monaco) where `type <selector>` doesn't trigger the editor's internal
event pipeline (beforeinput/DOM mutation).
- `keyboard type <text>` — page.keyboard.type() with real keystrokes
- `keyboard insertText <text>` — page.keyboard.insertText()
Note: `keyboard press` intentionally omitted — the existing top-level
`press` command already operates on current focus.

The warning "⚠ --annotate only applies to the screenshot command" fires
on every non-screenshot command when annotate is set in config. This is
noisy for users who set it as a persistent default.
Add cli_annotate tracking (matching the existing cli_* pattern) so the
warning only fires when --annotate is passed as a CLI flag.
Fixes#519. Playwright defaults `colorScheme` to `light` on all new contexts, overriding the browser/OS dark mode setting. This is especially disruptive in CDP mode, where every reconnection resets the scheme. The `set media dark` command also didn't persist its choice to new tabs or pages.
- Add `--color-scheme <dark|light|no-preference>` flag, config key (`colorScheme`), and env var (`AGENT_BROWSER_COLOR_SCHEME`)
- Store the preference in `BrowserManager` and automatically apply it to all new contexts (via Playwright's context option) and all new pages (via `page.emulateMedia` in `setupPageTracking`)
- `set media dark/light` now also persists its choice for subsequent pages and tabs
* feat: Enable capture of profiling data
Adding a new set of commands:
```
agent-browser profiler start
agent-browser profiler stop trace.json
```
With this, agents can start a profiling trace, perform a set of actions, and then extract the profiling data for analysis.
**Note:** I was originally going to call it `agent-browser profile` but I realized that might cause confusion with the `--profile` flag
CDP supports a couple commands for starting/stopping a trace.
When a trace is running, it emits events that need to be picked up.
We store these locally in the daemon until the trace is completed.
When the final event is received, we dump all of them into an output file.
That file can be loaded directly into chrome devtools or another analysis tool to visualize what happened during the agentic run.
Added some basic rust tests for parsing the commands (since they have some optional / required args)
TS daemon adds ~6 tests to make sure the profiling lifecycle (including saving the output file) works as intended

## Summary
- Return a `ParseError` when `--headers` receives invalid JSON instead of silently dropping the headers and proceeding
- Reject `frame` commands that provide no `selector`, `name`, or `url` (previously returned `{ switched: true }` without doing anything)
- Add missing mutual exclusion check for `--cdp` + `--extension` (extensions require a local browser, not a CDP connection)
## Summary
- Fix `allowFileAccess` being silently stripped from launch commands by adding it to the Zod schema in `protocol.ts` (the `--allow-file-access` CLI flag was not reaching the browser)
- Fix `trace stop` requiring a path argument despite help text documenting it as optional -- now works with or without a path
- Fix `addscript`/`addstyle` silently succeeding when neither `content` nor `url` is provided -- now returns a validation error
- Replace hardcoded ANSI escape code with `color::error_indicator()` in `main.rs` to respect `NO_COLOR`
- Fix double-parse pattern and add descriptive expect messages in `commands.rs`
- Fix incomplete string escaping in `snapshot.ts` `buildSelector` (use `JSON.stringify` instead of manual quote escaping)
- Simplify redundant ternary in `snapshot.ts` cursor-interactive role assignment
- Sync docs changelog with CHANGELOG.md (v0.8.1 through v0.10.0)
* docs: fix 6 documentation issues (#303, #245, #186, #134, #61, #73)
Addresses six open documentation issues in a single pass:
- **#303** -- Add `npx agent-browser` usage across README, SKILL.md, docs site, and `--help` output for zero-install experience. Global install is recommended as the fastest path (native Rust CLI vs Node.js indirection with npx).
- **#245** -- Document Claude Code skill installation with `npx skills add vercel-labs/agent-browser`
- **#186** -- Split installation instructions into Global (recommended), Quick Start (npx), and Project (local dependency) sections with clear guidance on when to use each
- **#134** -- Add "Why agent-browser over playwright-mcp?" comparison table to README covering output format, element selection, protocol, sessions, performance, mobile, cloud, and streaming
- **#61** -- Add "Timeouts and Slow Pages" section to SKILL.md documenting the 60s default timeout, all `wait` variants, and guidance for slow websites
- **#73** -- Replace stale `cp node_modules/...` advice with `npx skills add`, add warning against copying SKILL.md manually, add "Session Management and Cleanup" section to SKILL.md
* remove section
* fix doc
Rebased and fixed implementation of PR #184 features on current main:
Session persistence:
- --session-name flag and AGENT_BROWSER_SESSION_NAME env var auto-save/restore
cookies and localStorage across browser restarts
- State files stored in ~/.agent-browser/sessions/ with owner-only permissions
- AES-256-GCM encryption via AGENT_BROWSER_ENCRYPTION_KEY env var
- Auto-expiration of old state files (AGENT_BROWSER_STATE_EXPIRE_DAYS, default 30)
State management commands:
- state list: list saved state files with metadata
- state show <file>: display state summary (cookies, origins, domains)
- state rename <old> <new>: rename state files
- state clear [name] [--all]: clear saved states
- state clean --older-than <days>: delete expired states
New --new-tab flag for click command:
- Opens link href in a new tab instead of navigating the current tab
Security hardening:
- Session name validation prevents path traversal (CLI + daemon)
- safeHeaderMerge prevents prototype pollution in header merging
- WebSocket stream server binds to 127.0.0.1 only
- State files written with 0o600 permissions
Fixes applied over the original PR:
- Use color.rs module instead of hardcoded ANSI escape codes
- Align CLI output field names with daemon response format
- Add CLI-level --session-name validation (not just daemon-side)
- Avoid adding "DOM" to tsconfig.json lib (use proper typing in evaluate)
- Keep version at 0.9.3 (matches current main)
- Centralize session name validation in daemon.ts helper
- Update all documentation (README, SKILL.md, docs site, --help output)

* feat: add --allow-file-access flag for file:// URL support
Adds the ability to open and interact with local files using file:// URLs.
This enables use cases like viewing local PDFs, testing local HTML files,
and allowing JavaScript to access other local files via XHR.
The flag adds Chromium's --allow-file-access-from-files and --allow-file-access
launch arguments. Only supported in Chromium browsers.
Fixes#345
* fix: add cli_allow_file_access tracking to prevent spurious warning
When --allow-file-access is set via AGENT_BROWSER_ALLOW_FILE_ACCESS env var
(not CLI), don't warn about the flag being ignored when daemon is already running.
* fix: only warn about ignored flags when explicitly passed via CLI
The warning about launch-time options being ignored (when daemon is
already running) was incorrectly shown when options were set via
environment variables like AGENT_BROWSER_EXECUTABLE_PATH, even when
no CLI flag was passed.
Now the warning only appears when flags are explicitly passed on the
command line, not when values come solely from environment variables.
Fixes#372
* feat: add cursor-interactive element detection in snapshots
Add -C/--cursor flag to snapshot command that detects clickable elements
that don't have proper ARIA roles but are interactive based on:
- cursor: pointer CSS style
- onclick attribute/handler
- tabindex attribute
This helps with modern web apps that use custom divs/spans as buttons.
Fixes#366
* fix: add cursor option to getSnapshot type signature
The warning about launch-time options being ignored (when daemon is
already running) was incorrectly shown when options were set via
environment variables like AGENT_BROWSER_EXECUTABLE_PATH, even when
no CLI flag was passed.
Now the warning only appears when flags are explicitly passed on the
command line, not when values come solely from environment variables.
Fixes#372
* Add base64 input for eval command
Adds -b/--base64 flag to decode script from base64, avoiding shell escaping issues for AI agents.
* Document base64 eval in SKILL.md
* fix: add retry logic for transient socket errors
Fixes race condition when rapidly closing and opening browser sessions.
The daemon has a 100ms shutdown delay, which caused the CLI to detect
stale daemons as "running" and fail with EAGAIN errors.
Changes:
- Add retry logic (5 attempts, exponential backoff) for transient errors
including EAGAIN, EOF, connection reset, and connection refused
- Add 150ms verification delay in ensure_daemon to detect shutting-down daemons
- Add cleanup_stale_files to remove leftover socket/PID files before starting
a new daemon
Tested with 20 rapid close/open cycles and 100+ parallel commands.
* test: add unit tests for transient error detection
Extracts is_transient_error() function and adds 14 unit tests covering:
- EAGAIN errors (macOS os error 35, Linux os error 11)
- WouldBlock and Resource temporarily unavailable
- EOF and empty JSON response errors
- Connection reset (macOS os error 54, Linux os error 104)
- Broken pipe errors
- Socket not found (os error 2)
- Connection refused (macOS os error 61, Linux os error 111)
- Non-transient errors (verifies they are NOT retried)
