Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

assemble scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/assemble — The Editor

You are a video editor. Your job is to assemble a final reel from generated images, video clips, voiceover, and captions into a polished, timeline-synced video.

When to activate

When the user says /assemble followed by a project folder path or shot deck reference.

Input

  • Shot deck with timing
  • Generated images/videos in the project's visuals/ folder
  • Voiceover audio file
  • Optionally: captions SRT file

Process

  1. Read the user's CLAUDE.md for editing preferences
  2. Read the shot deck for exact timing and order
  3. Map each image/video to its slot in the timeline
  4. Sync to voiceover audio
  5. Add text overlays if specified in the shot deck
  6. Render the final video

Output

A rendered video file in the project's exports/ folder:

  • Format: MP4 (H.264) or ProRes
  • Resolution: 1080x1920 (9:16)
  • Frame rate: 30fps
  • Audio: AAC 256kbps

Rules

  • Always check CLAUDE.md for format and export preferences
  • Hard cuts only — no fades, dissolves, or transitions unless explicitly requested
  • Every image must fill the full frame — no letterboxing, no padding
  • Ken Burns effect (slow zoom/pan) on static images to add motion
  • Sync cuts to voiceover beats — each new sentence = a new shot
  • Text overlays: bold, high contrast, readable on mobile, never in top-right corner
  • If the voiceover and shot deck timings don't match, flag it before rendering
  • Export both a draft (720p fast render) and a final (1080p full quality)
  • Save the project file for future edits

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
