Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

generate

generate_linkedin_headlines

Profile headline options built only from the user's role, audience, outcome, proof and keywords. Every option fits LinkedIn's 220-character headline limit. Does not change the profile.

generate_linkedin_hooks

Opening-line templates for a LinkedIn post, filled with the user's topic, audience and result. Anything the user has not supplied stays in [brackets] to replace with a real detail; nothing is invented.

format

format_linkedin_post

Convert Markdown into text that pastes cleanly into LinkedIn: **bold** and headings become Unicode bold, *italic* becomes Unicode italic, list markers become bullets, Markdown links become plain URLs. Optionally replaces em dashes.

check_linkedin_post

Check a LinkedIn post before publishing: character count against LinkedIn's 3000-character limit, the text likely shown before "see more" on desktop, a hook score, Markdown that LinkedIn will not render, placeholders, and phrases that read as AI-written. Returns concrete issues to fix.

preview

preview_linkedin_post

Return a link to an approximate preview of the post in the LinkedIn feed on mobile and desktop, including about where "see more" cuts it. Pass author_name and author_headline when you know them. Opening the link saves and publishes nothing. The post text travels in the link, so share it only with people who should read the draft.

style

style_linkedin_text

Restyle a short piece of text with Unicode letters that keep their look when pasted into LinkedIn (bold, italic, bold italic, serif, cursive, strikethrough, underline). Use sparingly; screen readers may read styled letters poorly.
