🟢extract_design_md(url, max_stylesheets, include_raw_css)

Writes a starter DESIGN.md file from the CSS of one public webpage. Best for: a user who gives a website address and wants its colors, fonts, spacing, corner radii and component styles as a DESIGN.md file. Returns: markdown (the DESIGN.md text in the open Google format, YAML tokens then the 8 standard sections), the lint verdict of @google/design.md 0.4.0 on that text, the token counts and the number of stylesheets read. Pass url, such as "https://stripe.com"; a bare host such as "stripe.com" means https. Do not use for: pages behind a login, private or local addresses (localhost, 192.168.x.x), pages that robots.txt disallows, or a DESIGN.md file the user already has (use lint_design_md). Errors: blocked_url, invalid_url, robots_disallowed, fetch_failed and http_error each say what to send next.

🟢lint_design_md(text)

Lints one DESIGN.md file with the official @google/design.md 0.4.0 linter, the same check as `npx @google/design.md lint DESIGN.md`. Best for: checking a DESIGN.md file the user pasted before it goes to a coding agent. Pass the whole file contents in text, including the YAML front matter between the --- lines; a file path or URL will not work, so ask the user to paste the file. Returns: each finding with its severity, rule and token path (broken token references, low text contrast, missing primary color, unused colors, section order, unknown keys), the error, warning and note counts, the sections found and the token counts. The file is valid when it has no errors. Front matter that is not valid YAML comes back as a finding, not an error. Do not use for: comparing two versions (use diff_design_md) or reading a website (use extract_design_md).

🟢diff_design_md(base_text, target_text)

Compares two versions of a DESIGN.md file the way `npx @google/design.md diff` does. Best for: deciding whether a DESIGN.md change is breaking before it is merged. Pass the whole old file in base_text and the whole new file in target_text, each including the YAML front matter; a file path or URL will not work. Returns: every added, removed and modified token in colors, typography, rounded, spacing and components with its old and new value, breaking (true when a token was removed), regression (true when the new file has more lint errors or warnings), the lint counts before and after, and a markdown summary. Do not use for: checking a single file (use lint_design_md) or comparing two websites (run extract_design_md on each first).

🟡submit_feedback(kind, message, tool, error)

Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
