What is video-assets?

A workflow for managing promotional and demo videos as GitHub Release files instead of storing large video files in a code repository.

Use it to upload, replace, name, preview, and link cctop video assets through GitHub Releases.

It keeps repositories smaller and provides stable locations for videos and their preview images.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00120	$0.01326
Opus 5.5	$0.00048	$0.00530
Sonnet 5.5	$0.00024	$0.00265
Haiku 4.5	$0.00012	$0.00133

Security

Grade A, and why

video-assets 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 2mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/publish-launch-assets.sh, scripts/upload-video-asset.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Video Assets

Manage cctop video files as GitHub Release assets, not as committed repo binaries. The default pattern is one non-latest media release that acts as a stable asset bucket.

Rules

Default release tag: media-assets.
Default release title: Media assets.
Always create media-only releases with --latest=false.
Do not use a v* tag for media-only work. In cctop, v* tags trigger .github/workflows/release.yml: app builds, notarization, GitHub Release creation, Sparkle appcast, and Homebrew updates.
Attach a video to a real v* release only when the user explicitly asks and the video truthfully demonstrates that shipped app version.
Keep full MP4s and other large rendered video out of git. Do not commit video/projects/*/.video-build/.
Commit a small animated README preview only when the user explicitly chooses that route and the file is intentionally small.
Prefer stable purpose-based asset names over dates: cctop-launch.mp4, cctop-launch-720p.mp4, cctop-launch-preview.avif.
For launch video uploads, always generate and upload the AVIF preview alongside the MP4s so the README preview and full video stay in sync.

Workflow

Identify the source files.
- Launch defaults: video/projects/launch/.video-build/launch.mp4 and video/projects/launch/.video-build/launch-720p.mp4.
- Check existence and size with ls -lh.
- Check duration/codec with ffprobe when available.
Pick the release target.
- Use media-assets for reusable README/demo/launch assets.
- Use an existing app release such as v0.18.4 only with explicit user direction.
- Inspect before mutating: gh release view media-assets --repo st0012/cctop.
Pick stable asset names.
- Reusing the same asset name plus --clobber keeps the download URL stable.
- Use a new asset name when history matters or two variants should coexist.
- Remember: gh release upload file.mp4#Label sets a display label, not a stable download filename. Stage or copy the file to the intended asset filename before upload.
- Default launch asset set:
  - cctop-launch.mp4 from launch.mp4
  - cctop-launch-720p.mp4 from launch-720p.mp4
  - cctop-launch-preview.avif generated from launch-720p.mp4

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
