What it does

Video Assets is an agent skill from st0012/cctop. Use when publishing, replacing, auditing, or linking cctop promo/demo video assets through GitHub Releases, especially the non-latest media-assets release. Trigger for requests like "upload the launch video", "add another video asset", "replace the README demo video", "where should this video live", "update media-assets", or "generate the README AVIF preview". Covers stable asset names, release selection, AVIF preview generation, README/site links, and avoiding v product-release tags. Do not use for video…

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `agents/openai.yaml`, `scripts/publish-launch-assets.sh` and `scripts/upload-video-asset.sh`).

It sits in Media & Creative, covering Technical documentation, Video production and Comics and storyboards. It works with GitHub and macOS. The repository describes itself as: A keyboard-first menubar app to monitor and jump between AI coding sessions — minimum setup required. The licence is MIT.

When your agent uses it

  • Linking cctop promo/demo video assets through GitHub Releases
  • Especially the non-latest media-assets release
  • Requests like upload the launch video
  • Add another video asset

Example prompts

  • “upload the launch video”
  • “add another video asset”
  • “replace the README demo video”
  • “/video-assets”

Requirements

  • A Bash shell

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Identify the source files.
  2. Pick the release target.
  3. Pick stable asset names.
  4. Gate public mutations.
  5. Publish launch assets with the wrapper script. This is the default path for launch renders.

What it can do on your machine

Read from SKILL.md and the folder at commit 4ee2258. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Video Assets loads about 1.4k tokens when it runs. Until then it costs about 146 tokens; SKILL.md has 546 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~146
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Use when publishing, replacing, auditing, or linking cctop promo/demo video assets through GitHub Releases, especially the non-latest media-assets release. Trigger for requests like "upload the launch video", "add another video asset", "replace the README demo video", "where should this video live", "update media-assets", or "generate the README AVIF preview". Covers stable asset names, release selection, AVIF preview generation, README/site links, and avoiding v* product-release tags. Do not use for video narrative/storyboard work; use video-storyboard for that.

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

  1. 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.

  2. 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.

  3. 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

  4. Gate public mutations.

    • Before creating a release, uploading, or replacing assets, state: release tag, source file, asset name, whether --clobber will be used, and the resulting download URL.
    • Wait for explicit approval unless the user's latest request already clearly authorizes the upload/update.
    • Never publish a media release as latest.

  5. Publish launch assets with the wrapper script. This is the default path for launch renders.

Show full SKILL.md (189 more words)Show less
bash
.agents/skills/video-assets/scripts/publish-launch-assets.sh --clobber

Use --dry-run first when checking paths or explaining what will happen:

bash
.agents/skills/video-assets/scripts/publish-launch-assets.sh --clobber --dry-run

The wrapper:

  • Verifies both MP4s exist.
  • Generates a fresh animated AVIF preview from the 720p MP4 with ffmpeg.
  • Uploads all three assets to media-assets.
  • Keeps the stable download URLs unchanged by reusing the same asset names.
  1. Upload individual assets only for non-launch one-offs.
bash
.agents/skills/video-assets/scripts/upload-video-asset.sh \
  --file video/projects/launch/.video-build/launch.mp4 \
  --name cctop-launch.mp4 \
  --clobber

For another video:

bash
.agents/skills/video-assets/scripts/upload-video-asset.sh \
  --file path/to/other-video.mp4 \
  --name cctop-other-video.mp4

The stable download URL shape is:

text
https://github.com/st0012/cctop/releases/download/media-assets/<asset-name>

Launch URLs:

text
https://github.com/st0012/cctop/releases/download/media-assets/cctop-launch-preview.avif
https://github.com/st0012/cctop/releases/download/media-assets/cctop-launch-720p.mp4
https://github.com/st0012/cctop/releases/download/media-assets/cctop-launch.mp4
  • For an inline README animation, prefer the release-hosted AVIF preview and an <img> tag.
  • Use cctop-launch-preview.avif from the same media-assets release as the MP4s unless the user explicitly wants a committed preview file.
  • For the full video, link to the release asset URL.
  • Avoid releases/latest/download/... for media assets unless every future product release will carry the same asset name. cctop's README and site already use releases/latest for app downloads, so media assets should stay separate.

Helper

scripts/publish-launch-assets.sh is the preferred launcher for cctop launch renders. It creates a fresh AVIF preview and delegates uploads to scripts/upload-video-asset.sh.

scripts/upload-video-asset.sh creates media-assets if needed with --latest=false, stages the file under the intended asset filename, then uploads it. It refuses v* tags unless passed --allow-v-tag.
