Capabilities
PostNitro social posting — Use this when a user wants to connect PostNitro and set up posting of carousels, single images, and videos for their own brand.

Routines & automation
Daily posts with PostNitro — Creates today's posts for the user's brand with PostNitro and schedules them in the chosen publish windows.
Memories
Profile — Posts are the user's brand or product content: educational and problem-solving first, not founder voice unless they ask. PostNitro is the create + design + schedule tool, not the subject of the posts.
Profile — PostNitro is an AI-powered platform that writes social content, designs carousels/image posts/videos, and schedules/publishes natively to LinkedIn, Instagram, TikTok, and Threads. AI can generate slide copy from a topic, article URL, X post, or the user's own text; users can also import their own slides. Tagline: Design. Schedule. Publish. Used by 82,000+ creators; editor is embedded in 200+ platforms. Source of truth for product facts: https://postnitro.ai/llms-full.txt and https://postnitro.ai
Profile — Social content should be problem-solving and relatable (ideas that take minutes, production that takes hours, posting that slips), with the user's product or offer fitting as the solution at the end, not generic self-promotional claims. Lock slide copy as text with the user before importing or scheduling.
Profile — Scheduled-post rules: generateImages on with imagePlacement auto and imageStrategy strategic (agent writes generateImages.context). Instagram postType matches the asset (carousel/image/reel); postAsStory is required. TikTok: privacyLevel PUBLIC_TO_EVERYONE when SCHEDULED; carousel needs autoAddMusic; reel needs canDuet and canStitch; branded-content flags default false. LinkedIn carousels always use postType document (postTitle 5–90 chars when SCHEDULED). Threads postType matches the asset.
Profile — Instagram scheduled posts use postAsStory true (feed + story). Carousel/video output stays DESIGN, not PDF. TikTok isAIGeneratedContent is false for now.
Profile — Reel videoDuration is variable, floor 5s per slide when it fits, cap 50 seconds (API max is under 60). Before writing daily posts, list scheduled posts for the past 30 days filtered by connected socialAccountIds to avoid topic duplication. Choose reel audio from the workspace library to match the post mood: stomp-drum (energy), moment-of-peace (calm/educational), corporate-hustle (professional), kontraa-water (afro-pop).
Profile — TikTok scheduled posts only support carousel (multiple images) or reel (video). A single-image post must be scheduled to TikTok as a separate reel scheduled post, not as carousel or image. Daily content should be educational: strategies, tips, and tricks, problem-solving first.
Profile — Daily posts include three formats: carousels, single-image posts, and videos. Rotate the mix. TikTok still cannot take a single image; that format needs a separate TikTok reel scheduled post.
Profile — TikTok scheduled posts must include postTitle (use the post's title). Captions are a single line of text with no markdown or real newlines; use <br/><br/> for line breaks.
Log — This bot uses PostNitro to write, design, and schedule carousels, image posts, and videos to LinkedIn, Instagram, TikTok, and Threads. Connect PostNitro after import; it is not a marketplace plugin.
Log — Do not undersell PostNitro as a scheduler or design-only tool. It writes content (from a topic, article URL, X post, or pasted text), designs the slides or video, and then schedules/publishes.
Log — Carousel drafts should use infographic slides where they help (layoutType infographic): cycle for sequential steps, grid for comparisons, max 3 columns, unique ids, HTML descriptions. Mix with normal text slides; do not make every slide an infographic.
Log — For carousel drafts, keep first (hook) and last (close) slides moderate length—hook builds curiosity to keep scrolling, close wraps up; put the real diagnosis and explanation on the body slides.
Log — Reel/video postSettings: videoDuration is variable (floor 5s per slide when it fits, cap 50 seconds, always at least 5). Choose audioId from the workspace library to match post mood. postSettings applies when any selected platform postType is reel.
Log — Slide copy uses HTML-like tags with restraint: <c> highlights 1–3 emphasis words per headline and is never combined with <u>; <strong> for the single most important phrase per slide (max one); <em> italic; <br/><br/> for line breaks. Daily carousels and videos are 5 to 7 slides (1 start, 1 end, 3–5 body).
Log — CTA rotation: one CTA per post (Save / Share / Follow), different from the most recent post; use Follow sparingly (about 1 in 3); no engagement bait or fake urgency.
Log — Single-image posts use one slide object (not an array) with no slide type; only heading is required; infographic layout is allowed on that slide.
Log — AI images need a paid PostNitro plan and a separate quota from post credits; confirm they landed via the GENERATE_IMAGES step in check_status. Infographic slides never receive an image. generateImages.context should keep the focal subject in a lower/side third with clean negative space for the heading, high contrast, one visual metaphor, and no text in the image.
Log — Unattended daily jobs cannot schedule public TikTok posts: a safety check requires the user at the keyboard, and approval retries may not reach the user. Book the separate TikTok reel for single-image posts while the user is present.
