The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.

• get_review

  Fetch a Cobalt Capture review by its share link or slug. Returns the reviewer's notes as text AND each annotated screenshot as an image, so you can see exactly what was marked and what to change.

• create_review

  Start a new Cobalt Capture review and get a handle for filling it in. Use this to compile the findings of any site study — a usability pass, a pricing teardown, a positioning audit, a QA run — into one shareable, durable report with real screenshots. Works from any client, chat assistants included: with no browser, add_screenshot(page_url=...) renders the pages for you. Returns a `review` slug and a `claim_token` — pass BOTH back to add_screenshot / add_note to append content. Also returns a `review_url` to share and a `save_url` the human opens (while signed in) to save the review to their ac

• add_screenshot

  Append one screenshot, with an optional title and note, to the end of a review. The image is stored in Cobalt and shown in the review. Three ways to supply it: `page_url`, a public page that Cobalt renders in a headless browser (`viewport` 'desktop' at 1280px or 'mobile' at 390px, `full_page` for the whole scroll, `hide_selectors` for elements to hide; common cookie banners are hidden automatically), which also returns the rendered image; `image_url`, an image already uploaded to https://cobaltcapture.com/api/upload; or `image`, a small base64 image. This tool only appends; it never changes an

• replace_screenshot

  Overwrite one existing screenshot in a review with a new capture, in the same position. Destructive: the old image and any pins or annotations on it are removed and cannot be recovered; the title and comment change only if new ones are passed. Works on screenshots only, not notes. Takes the same capture arguments as add_screenshot, plus `item`, the 1-based number of the screenshot to replace.

• add_note

  Append a free-standing text note (not tied to a screenshot) to a review created by create_review. Use for context, steps taken, or a summary of findings between screenshots.
