10 steps · 3 from verified skills- Step 1tool
Preflight: before doing any work, make sure everything this agent needs is in place, so the run never fails halfway on a missing tool or an unconfigured account. Command-line tools (free, auto-install only if missing; idempotent, later runs find them present): Remotion - npx remotion versions (auto-fetches), or npm i remotion in the project. Services and accounts (these need a key, login, or subscription, NOT auto-installed): Runway ML (usage-based credits; get it at dev.runwayml.com; alternative: Seedance via HeyGen for image/video generation); HeyGen (free trial, then paid; get it at heygen.com). Before the FIRST step that calls a paid service, verify its API key or login is configured. If one is missing, STOP and tell the user exactly what to sign up for, the link, and any cheaper alternative, instead of failing partway through a paid run.
Your model fills this step - Step 2
Draft the reel script, hook, and per-scene B-roll visual descriptions from the topic and talking points. Save the full storyboard to ~/Implexa Agents/instagram-reel-generator-heygen-runway-remotion/storyboard-YYYY-MM-DD.md, including: scene timecodes, avatar dialogue, Runway B-roll prompts (one per clip), HeyGen avatar script block, and Remotion composition plan.
Your model fills this step - Step 3decision
Present the storyboard to the user for review. Invite feedback on hook strength, scene flow, dialogue, B-roll prompts, and total duration. Incorporate any revisions into the storyboard file before proceeding. Stage the revised storyboard as awaitingApproval=true — do NOT submit to HeyGen or Runway until the user approves. This gate saves paid credits by catching issues before generation.
Decision step - Step 4tool
Submit the approved avatar script to HeyGen via logged-in Chrome, select the saved avatar (Sanna Realtor portrait mode black dress) and voice (Sanna Realtor 5), start generation, poll until the video is ready, then download the MP4 to the assets folder.

Review the HeyGen spokesperson video and all Runway B-roll clips — approve to proceed to compositing or flag specific clips for regeneration before moving on.
Decision step - Step 7
Write a Remotion composition that layers the HeyGen avatar clip, B-roll clips, captions, and transitions in a 9:16 1080x1920 Instagram Reel timeline (no background music track unless explicitly requested). Render via Remotion CLI to an MP4. Save the project to remotion-YYYY-MM-DD/ inside the agent folder.

Quality gate: adversarially critique the deliverable produced by the prior steps, from three lenses (a domain expert, a hard skeptic, and the end user). Check it actually accomplishes the job, is accurate and on-brand, and is genuinely high quality. Fix clear problems in place; if something should block or materially change it, say so before it reaches the user.
