sonilo-ai/skills
Agent skills for the Sonilo audio API that score a finished video with music, add matched sound effects, dub speech into other languages and duck music under dialogue.
video-to-music, video-to-sfx and video-to-sound take a finished video and return a score, matched sound effects, or both mixed, either as an audio file or as a video with the track added. video-analysis generates no audio and instead returns a music plan, a sound-design brief and ready-made prompts from the footage; auto-dubbing and proofread handle translated speech, with editable SRTs to approve before the dub, and audio-ducking lowers music under a voice track. text-to-music and text-to-sfx cover cases without footage, and four helper skills handle API-key setup, account limits, recovering timed-out tasks and local playback. Calls go through the Sonilo MCP server or CLI, are billed from a prepaid balance after a few free trial runs, and need a Sonilo sign-in or API key.
Included skills
01From the README
The install command quoted from the repository README.
npx skills add sonilo-ai/skills02Claude Code, skills folder
Copy the skill's folder, the one that holds SKILL.md, into ~/.claude/skills/ to use it in every project on your machine, or into .claude/skills/ in a repository to use it there and share it by committing it. Claude Code picks up changes to these folders during a session. If the folder did not exist when the session started, run /reload-skills.
03Claude Code, plugin marketplace
Some repos publish a plugin marketplace, a .claude-plugin/marketplace.json file. Add it in Claude Code, then install a plugin from it with /plugin install plugin-name@marketplace-name. Plugins can bundle hooks and MCP servers along with skills, so read the details panel before you confirm.
/plugin marketplace add sonilo-ai/skills04Codex, skills folder or $skill-installer
Codex reads skills from .agents/skills in your working folder and its parent folders up to the repository root, and from $HOME/.agents/skills for every repository. Copy the skill's folder into one of them, or run $skill-installer inside Codex and ask it to install from the repo. Codex detects new skills automatically and needs a restart only if one does not appear.
The first command is quoted from the author's README. The others are the standard ways to install a skill from a GitHub repository. They are templates and may not apply here, for example if the repo has no plugin marketplace, so follow the README first.
The production stages this skill covers, and where Pencil0 picks up.
heygen-com/hyperframes
HeyGen's 21 skills for its open-source HTML-to-video framework: an agent plans, codes and renders explainers, launch videos, captions and music-synced clips as deterministic MP4s.
browser-use/video-use
A skill that lets a coding agent edit raw footage by conversation: it cuts from a word-level transcript, grades color, adds overlay animations and subtitles, then checks its own render.
yikart/AiToEarn
Video-focused SKILL.md files from the AiToEarn content agent, led by a short-drama recap skill that submits clips for AI narration and voice-over; they rely on the platform's own tool calls.
luoluoluo22/jianying-editor-skill
Lets a coding agent script the desktop JianYing Pro app (CapCut's China edition): import media, add subtitles, TTS voiceover, music, effects and keyframes into an editable draft.
FireRedTeam/FireRed-OpenStoryline
A conversational video-editing agent whose editing workflows ship as skills, plus two skills that let Claude Code or OpenClaw install it and run an editing session.
samuelgursky/davinci-resolve-mcp
Agent skills shipped with a DaVinci Resolve MCP server, covering grading, editing, conform, Fairlight audio, delivery QC, Fusion, media-pool ingest, footage analysis, rough cuts and dead-air removal.
This is a third-party skill. It is not maintained or audited by Pencil0, and skills can run scripts on your machine, so read the SKILL.md and any scripts before installing. Stars, license and dates are a GitHub snapshot and may be out of date.
