Charlotte tools 23
charlotte_navigateLoad a URL in the active page. Returns page representation after navigation. Default minimal detail includes landmarks, headings, and interactive element counts — use charlotte_find to locate specific elements, or pass detail: 'summary' to get the full element list.charlotte_backNavigate back in browser history. Returns page representation after navigation.charlotte_forwardNavigate forward in browser history. Returns page representation after navigation.charlotte_reloadReload the current page. Returns page representation after reload.charlotte_observeGet current page state without performing any action. Use detail levels to control verbosity: "minimal" for landmarks, headings, and interactive element counts by landmark (use charlotte_find to get specific elements with actionable IDs, or observe({ detail: "summary" }) to see all elements), "summary" (default) for content summaries and full element list, "full" for all text content. Use view: "tree" for a compact structural outline (cheapest orientation tool), or view: "tree-labeled" to include labels on interactive elements (still much cheaper than minimal JSON, and shows which button/link/input is which).charlotte_findSearch for elements matching criteria. Filters interactive elements by text, role, type, or spatial proximity. Use the selector parameter to find DOM elements by CSS selector — this reaches elements not in the accessibility tree (custom widgets, non-semantic divs). Selector results return Charlotte element IDs usable with click, hover, drag, etc.charlotte_screenshotCapture a visual screenshot. Fallback for when structured representation isn't sufficient (complex visualizations, canvas elements, images). Use save: true to persist as a file artifact that can be referenced later.charlotte_screenshotsList all saved screenshot artifacts. Returns metadata for each saved screenshot including ID, filename, page URL, and timestamp.charlotte_screenshot_getRetrieve a previously saved screenshot artifact by its ID. Returns the image data and metadata.charlotte_screenshot_deleteDelete a saved screenshot artifact by its ID. Removes the file from disk.charlotte_diffCompare current page state to a previous snapshot. Returns structural diff showing added, removed, moved, and changed elements.charlotte_clickClick an interactive element on the page. Returns full page representation after the click.- +11 more on the listing page
