Fine to try. Some of what it can do is expected: a media skill usually calls an AI service over the internet.

Turn a product release (the list of shipped items plus real screen recordings) into a motion recap video and one explained demo per feature, with sound effects tied to on-screen motion and a composed music bed. Deterministic HTML scenes rendered frame by frame, ElevenLabs for sound effects and music, ffmpeg for the mix. Use when asked for a release video, a changelog video, a feature recap reel, or demo clips for release notes and docs.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'release-video' ] || [ -L ~/.agents/skills/'release-video' ]; then echo 'A skill folder named release-video already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/huytieu/COG-second-brain' "$d" && git -C "$d" checkout --quiet '144c7a3a959cc99538b7dfee9c22c4b065a0e156' -- '.claude/skills/release-video' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/release-video' ~/.agents/skills/'release-video' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'release-video' ~/.claude/skills/'release-video' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
