 - **Blocking calls.** SeleniumBase's calls are synchronous and will block the server while a page loads or an element is waited on. For a single-user local tool this is fine; for a multi-client server you'd want to run them in a thread pool via `asyncio.to_thread`.
 
+- **`start_browser` retries once before failing.** If the first launch attempt raises, it's retried once automatically before returning an error. This was added after seeing occasional first-attempt failures when testing against Glama's MCP Inspector; it costs nothing on the common case where the first launch already succeeds.
+
 - **Errors surface as descriptive strings.** Every tool (aside from session-lifecycle tools, which handle their own errors) is wrapped by a `handle_sb_errors` decorator: if a selector isn't found or an assertion fails, `sb_cdp.Chrome` raises an exception, and the decorator catches it and returns a string like `Error in click: NoSuchElementException - ...` instead of a raw tool error. This lets the calling agent read the failure and self-correct (e.g. by waiting longer or trying a different selector) rather than just seeing an opaque tool-call failure.
 
-- **No standalone session-status tool.** There is no separate `browser_status`-style tool. `get_page_info` doubles as the status check: it returns `{"running": False}` (optionally with an `error` field) when there's no active session or the session errors out, and full page metadata (`running: True`, `url`, `title`, `origin`, `user_agent`, `history`) otherwise.
+- **No standalone session-status tool.** There is no separate `browser_status`-style tool. `get_page_info` doubles as the status check: it returns `{"running": False}` (optionally with an `error` field) when there's no active session or the session errors out, and page metadata (`running: True`, `url`, `title`, `origin`, `user_agent`) otherwise. `get_page_info` does not include navigation history — that lives on `manage_history(action="list")` instead (see below).
+
+- **Navigation and history live in one tool: `manage_history`.** What used to be `navigate_history` is now `manage_history`, and it gained a fourth action: `"list"`, which returns the browser's navigation history as `{"position": <0-indexed current entry>, "entries": [...]}`, where each entry has `id`, `url`, `user_typed_url`, `title`, and `transition_type`. `"back"`, `"forward"`, and `"reload"` behave as before. This is the only way to retrieve navigation history now — `get_page_info` doesn't return it.
 
 - **Content reading is consolidated into one tool.** `get_content` replaces what used to be three separate reads: page/element text, page/element HTML, and page-linked URLs. Pick the mode with `output_format` (`"text"`, `"html"`, or `"urls"`) rather than calling a dedicated `get_page_content` or `get_all_urls` tool — those no longer exist. Likewise, there's no standalone `get_user_agent` tool anymore; the User-Agent string is one of the fields returned by `get_page_info`.
 
+- **`check_condition` is deliberately narrow.** Its `check` parameter only accepts `"present"` or `"visible"` — there's no built-in `"count"` check anymore; call `find_elements` and read the returned `count` field instead. Passing `text` checks whether that text is visible within `selector` and takes priority over `check` when both are given — so `check_condition(text="Sign in")` behaves differently from `check_condition(check="visible")`, not as two variants of the same check. Note that an empty string for `text` (or for `wait_for`'s `selector`/`text`) is treated as not provided, since both tools now branch on truthiness rather than on `is not None`.
+
+- **`find_elements` defaults to a fast, non-raising lookup.** Its default `timeout` is 0.5 seconds (not 7, unlike most other tools here), and a failed lookup returns `{}` instead of raising — there is no error string on a miss, just an empty dict. Pass a longer `timeout` explicitly if the elements you're looking for may still be loading.
+
 - **Hover, click-after-hover, and drag-and-drop share one tool.** `hover_with_action(selector1, selector2, action)` replaces the earlier separate `hover` and `drag_and_drop` tools. `action="none"` hovers `selector1` only; `action="click"` hovers `selector1` then clicks `selector2` (useful for dropdown/submenu items revealed by hovering); `action="drag_and_drop"` drags `selector1` onto `selector2`. (`selector2` is required when `action` is `"click"` or `"drag_and_drop"`.)
 
 - **Non-activating element actions are `focus_on`.** What used to be `act_on_element` is now `focus_on(selector, action)`, with actions `scroll_to_element` (the default), `focus`, and `highlight` — note the default action changed from focusing the element to scrolling it into view. None of these actions click, type into, select from, or otherwise activate the element; use `click`, `type_text`, `select_option`, or `hover_with_action` for that.
