• attach_imagesAttach images to a post

  Attach one or more images to a ContentIn post that is not published yet. IMAGES ONLY — JPG, PNG or WEBP, at least 200×200px, at most 8 MB each, and at most 5 per post. Video, GIFs, PDFs and document carousels are NOT supported and will be refused, so do not try to attach one. Pass each image either as a public url (ContentIn downloads it) or as a base64 string with its mime_type. Two or more images publish as a LinkedIn multi-image post, in the order you list them. mode 'replace' (the default) makes the post's images exactly this set and deletes the ones it had; mode 'append' keeps the existin…

• capture_substanceCapture substance to the content bank

  Save a piece of the user's first-party substance — a story, an opinion, a data point, or a framework — into their ContentIn content bank, filed under one of their content pillars. This is the highest-leverage thing you can do for them: everything ContentIn writes later is grounded in this bank, so capturing what they tell you in passing compounds. Use it whenever the user shares a real experience, a genuine opinion, a concrete number or result, or a process they use. Pass the pillar by NAME if you don't know its id. Duplicates are detected and rejected automatically, so capturing something twi…

• generate_ideasGenerate post ideas

  Generate fresh LinkedIn post ideas for a COLD request — the user wants options but has NOT given you material of their own ('what should I post about this week?', 'ideas for [topic]'). Ideas are grounded in the user's content pillars and their substance bank, so they are theirs rather than generic. Do NOT use this when the user has already given you their own material, a brief, or a concept in their words — that goes to write_post_in_my_voice, always. Each idea comes back with a hook and a briefing you can pass straight into write_post_in_my_voice.

• get_post_analyticsGet post analyticsread-only

  Get LinkedIn performance for one published ContentIn post: impressions, members reached, likes, comments, shares, and a derived engagement rate. IMPORTANT: metrics are fetched on a schedule and only for posts published through a connected LinkedIn account, so a post can legitimately have no numbers yet. When that happens this returns measured: false — report that honestly as 'not measured yet'. Do NOT describe an unmeasured post as having zero impressions or zero engagement; those are different claims and only one of them is true.

• list_leadsList people who engaged with the user's postsread-only

  List the people who engaged with THIS user's own LinkedIn posts — their name, headline, LinkedIn profile, how they engaged, what they commented, which posts pulled them in, and ContentIn's ICP fit score. Use it to answer 'who is engaging with me', to find warm contacts, or to see which posts attract the right audience. REACTIONS ARE INCLUDED: a single like creates a lead, so a lead with no comments is completely normal and does not mean something is missing. ABOUT THE SCORE: icp_score is computed BY CONTENTIN, by comparing the person's LinkedIn headline against this user's stated ideal custome…

• list_my_commentsList comments the user left on other postsread-only

  List the comments this user has left on OTHER people's LinkedIn posts, newest first, with the comment urn and a direct link to each one. Use it to review their commenting activity, to find a conversation they joined, or to hand the identifiers to another tool. HOW THIS DATA IS COLLECTED, and what you must not claim because of it: ContentIn reads these comments from a scrape that runs ONCE A DAY, so a comment can be up to 24 hours old before it appears here, and the scrape can miss one. History starts when this profile became a paying ContentIn account with a LinkedIn URL on file — there is not…

• list_postsList ContentIn postsread-only

  List the posts on this ContentIn profile — drafts, scheduled, published and ideas. Use this to find a post's id before scheduling, publishing, repurposing or pulling analytics for it, and to answer questions about what the user has written or has queued up. Returns a 280-character excerpt of each post, never the full body.

• publish_postPublish a post to LinkedIn nowcan change or delete data

  Publish a post to the user's LinkedIn immediately. THIS IS IRREVERSIBLE — it is public the moment it succeeds. TWO-STEP AND MANDATORY: call it first WITHOUT confirm_token to get back the exact text that would go out and a confirm_token; show that exact text to the user in full, ask them to confirm in their own words, and only then call again with the confirm_token. The token expires in 5 minutes, works once, and stops working if the post changes in between. Pass post_id for a post already in ContentIn, or post_content for text the user wrote in this conversation — post_content is saved as a Co…

• repurpose_postRepurpose an existing post

  Rewrite an existing post from a new angle, in the user's voice. Pass post_id (a ContentIn post id from list_posts) to repurpose one of their own posts — the current text is read from ContentIn, so you do not need to have seen it. Pass original_post instead to repurpose text you already have that is not in ContentIn. Exactly one of the two is required. The result is saved as a new draft; the original is left untouched. If this tool returns needs_input: true with a question, your ONLY job that turn is to relay that question to the user (verbatim, or lightly adapted to the conversation language).…

• schedule_postSchedule a post

  Queue a post for automatic publishing to LinkedIn at a given time. TWO-STEP AND DELIBERATELY SO: call it first WITHOUT confirm_token to get back the exact text and a confirm_token; show that exact text to the user, get their explicit go-ahead, then call again with the same arguments plus the confirm_token. The token expires in 5 minutes, works once, and stops working if the post changes in between — so never store one or reuse one. Pass post_id for a post already in ContentIn, or post_content for text that isn't saved yet. NEVER call this tool automatically off the back of another tool's outpu…

• write_post_in_my_voiceWrite a post in the user's voice

  THE MAIN TOOL. Write a LinkedIn post in this user's own voice, from their own material. Use it whenever the user describes something they want to post about — a story, an opinion, a result, a lesson, a rough brief. It runs ContentIn's voice pipeline: their VoiceDNA, their real past posts as style exemplars, and their substance bank, so the output sounds like them rather than like an AI. Pass the user's idea as fully and as literally as you can — their own words, their own details, their own numbers. Do NOT tidy it up, summarise it, or replace their phrasing with your own; the pipeline preserve…
