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

generate-trailer 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 12d 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.

/generate-trailer

Analyze the screenplay and generate a curated trailer -- selecting the most compelling moments, generating panel images, and creating video clips.

Usage

/generate-trailer --project <project-dir> --duration <1m|3m>

Arguments

  • --project: Project output directory (required)
  • --duration: Trailer length -- 1m for 1-minute teaser (10-15 shots) or 3m for 3-minute theatrical (25-40 shots). Default: 1m
  • --model: Video model to use (optional, default: kling-o3-pro-image-to-video). Options: kling-o3-pro-image-to-video, vidu-q3-image-to-video, veo3.1-fast-image-to-video

What This Does

Phase 1: Screenplay Analysis

  1. Load project.json and read all scene data
  2. Analyze the dramatic arc: world, inciting incident, protagonist journey, central tension
  3. Identify the most visually striking and emotionally resonant moments
  4. Follow the trailer-curator agent's methodology (see .agents/agents/trailer-curator.md)

Phase 2: Shot List Curation

  1. Select 10-15 shots (1m) or 25-40 shots (3m) from across the screenplay
  2. For each shot, determine:
    • Scene source and specific moment
    • Shot composition (type, camera, framing)
    • Duration in the trailer
    • Audio layer (dialogue, SFX, ambient)
    • Whether an existing storyboard panel can be reused
  3. Arrange shots into the trailer's pacing structure:
    • 1m: Atmosphere (slow) -> Intrigue (medium) -> Escalation (fast) -> Title
    • 3m: Status Quo -> Inciting Incident -> Rising Stakes -> Cliffhanger -> Title
  4. Save the shot list as output/<project>/trailer/trailer-plan.json
  5. Present the shot list to the user for review before generating

Phase 3: Panel Generation

  1. Create output/<project>/trailer/ directory
  2. For shots that reuse existing panels: symlink or copy from scene-NNN/
  3. For new shots: generate via Venice API using:
    • The project's locked aesthetic profile
    • Full character descriptions from character locks
    • nano-banana-pro model, 1K resolution, 16:9 aspect ratio
  4. Save as shot-T01.png, shot-T02.png, etc.
  5. Generate corresponding shot-TNN.video.json for each panel

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.
