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

video-editor 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 6d 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.

Video Editor — Professional Post-Production

Companion skills: remotion · video-gen · faceless-youtube

When to Use

Trigger phrases:

  • "edit this video" · "add captions" · "color grade" · "make a promo video"
  • "merge clips" · "add music" · "watermark" · "optimize for instagram"
  • "speed ramp" · "slow motion" · "lower third" · "add transitions"

Use cases:

  • Post-production editing of AI-generated or recorded footage
  • Adding captions/subtitles with brand styling
  • Color grading and visual correction
  • Audio mixing, ducking, and loudness normalization
  • Creating promotional videos from raw clips
  • Platform-specific export (YouTube, TikTok, Instagram, LinkedIn)
  • Batch processing multiple videos
  • Thumbnail extraction and creation

When NOT to use:

  • When creating video from scratch with React (use remotion)
  • When generating video from AI models (use video-gen)
  • When the task requires real-time editing (use a NLE like DaVinci Resolve)

Overview

FFmpeg is the industry-standard tool for video post-production. This skill covers professional-grade filter graphs for promotional videos: color grading, audio design, kinetic text, transitions, motion effects, and multi-platform export.

Process

  1. Ingest — Analyze source footage (duration, resolution, codec, audio levels)
  2. Assembly — Trim, arrange, and concatenate clips
  3. Color grade — Apply LUTs, curves, contrast, and color harmony
  4. Audio design — Mix music, voiceover, SFX; apply ducking and normalization
  5. Add text — Captions, lower thirds, title cards, CTAs
  6. Add brand — Logo overlay, watermark, consistent color scheme
  7. Transitions — Crossfade, wipe, or zoom between scenes
  8. Motion effects — Speed ramps, slow-mo, Ken Burns, motion blur
  9. Export — Master file + platform-specific optimized versions
  10. Thumbnail — Extract best frame, add text overlay

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.
