Matches of fixed checks, with the text they matched.
- Warndraft_posts
The server marks "draft_posts" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

Can't be undone 1Claude Code: ask
submit_feedbackSend 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.No findings
Why it is in this group
- The name "submit_feedback" says "submit": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
Description, as the server wrote it 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.

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "draft_posts" says "post": a word for a change.
Description, as the server wrote it Use this when the user wants social posts written about a topic, such as "write posts about our new CLI for X, Bluesky and LinkedIn". Pass the topic, with every fact and any link to include, and 1 to 6 platforms from x, bluesky, threads, mastodon, linkedin, instagram, reddit, youtube, pinterest, tiktok; optionally a tone. Returns one draft per platform with its length as that platform counts it, hashtags, whether it passes the platform's rules and the issues if not, plus a checklist of rules and image sizes with sources and dates. Uses only the facts given. It does not publish, read accounts or fetch trends or statistics.

draft_tiktok_slidesUse this when the user wants to test an app idea with TikTok slideshows before coding, such as "make 4 slideshows for this idea".No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it Use this when the user wants to test an app idea with TikTok slideshows before coding, such as "make 4 slideshows for this idea". Pass idea, and angles 3 or 4 (default 4). For a product or a new account, also pass angle_lines: 3 or 4 angles you wrote, each with name, hook, pain, stake, reveal and cta, and optionally caption and hashtags; the slides then show only those lines. Pass plan_days 7 to 14 for a posting plan of the first days. With angle_lines each slide comes as png_url, a link to its PNG, unless images is true. Returns that many angles, each with 5 slides (hook, pain, stake, reveal, cta) as 1080x1920 PNGs in png_base64, one caption and a hashtag list. Quote the summary field first: it has the counts and the first caption. Save png_base64 as its filename only when the user asks for the files. Stake is the second pain beat. The reveal invites the comment what is the app. The same page is at /slides. One call is one plugin-call. It does not publish or store the idea.

Description, as the server wrote it Use this when the user wants a script for a short vertical video, such as "write a 25-second TikTok and Reels script about our new app". Pass the topic, with the facts to use, and 1 to 4 platforms from tiktok, youtube_shorts, instagram_reels, x_video; say in the topic if an AI-generated presenter or voice will be used. Returns a script on a fixed clock (hook 0 to 3 seconds, body 4 to 20 seconds, call to action by about 25 seconds) with voiceover, on-screen text and visuals, a timing check, a caption for each platform checked against its rules, each platform's official video length limit with its source, and an ai_disclosure block naming the AI label that applies when the script declares an AI-generated person or voice. Uses only the facts given. It does not publish, make the video, clone voices or write for fake-identity accounts.

Description, as the server wrote it Use this when the user wants a post they wrote adapted for readers in another country or language, such as "adapt this for a Japanese audience". Pass the post text, the target market and optionally a platform to check the result against. Returns the adapted text, its language, a short list of what changed and why, and the platform check when one was asked for. It adapts tone, idioms, examples and formats rather than translating word for word, and adds no new claims. Only for the user's own text; it does not publish.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
