Coco Ads Agent Skill

/coco-ads — launch videos from your repo

You built it. Now let CoCo make the ad.

/coco-ads turns the current project into a short (15–25s), polished, shareable launch video using the HyperFrames toolchain, rendered locally. It is narrow, opinionated, and fast.

> Credit / lineage. This skill adapts the launch-video flow from brag by Shunit Haviv and runs on the HyperFrames HTML-composition + render engine by HeyGen. Bundled music is "Happy Beats / Business Moves" by ende.app; bundled SFX are CC0 (Kenney.nl). See CREDITS.md. Re-implemented in CoCo's voice with attribution. Upstream brag is MIT-licensed (Copyright (c) 2026 Shunit Haviv Hakimi); its notice is retained at LICENSE in this skill directory.

Requirements

The render path is fully local (HeyGen cloud/Lambda paths are never used). It needs:

• Node 22+ and FFmpeg on PATH.
• The HyperFrames CLI, run via npx hyperframes … (auto-fetched on first use). The composition skills install once with npx hyperframes skills.
• A quick environment check: npx hyperframes doctor (Chrome headless-shell + FFmpeg). "Docker not running" is fine — Docker is only for distributed cloud renders, which this skill does not use.

No data leaves the machine on the default render path. If GEMINI_API_KEY is set, the optional snapshot frame-analysis would call Gemini — keep it off (--describe false) when bragging about anything you would not paste in public.

What this skill does

• Reads the current project code to understand the app.
• Plans a short concept specific to this project.
• Scripts and storyboards the video.
• Hands a focused composition brief to HyperFrames.
• Validates, renders locally, and writes share copy.

Parsing the invocation

/coco-ads
/coco-ads --tone chaotic
/coco-ads --tone polished --format vertical
/coco-ads this. Make it feel like a ridiculous startup launch.

| Option | Values | Default |

|---|---|---|

| --tone | preset or freeform description | inferred |

| --format | landscape, vertical, square | landscape |

| --duration | seconds | auto (15-25s) |

| --no-music | flag | music on |

| --no-sfx | flag | sfx on |

| --title | string | inferred from project |

Tone can be a preset (default, polished, yc-parody, chaotic, deadpan, cinematic, app-store) or a creative direction such as "fake Series A launch from 2016". When the user gives freeform direction, map it to the nearest preset for pacing and structure, but preserve the user's direction in the plan and composition brief.

Output directory

By default, output goes to coco-ads-output/. To avoid overwriting previous runs, use a timestamped directory (coco-ads-output-YYYY-MM-DD-HHmmss/) when the user asks for a new run or one already exists. Generate the timestamp once at the start of the run and use it consistently for the plan, brief, composition, render, and share copy. Keep coco-ads-output/ out of version control.

Step 1: Inspect the project

Read: references/step-1-inspect.md

Scan the project directory and extract what you need to plan the video.

Gate: You can answer all 9 questions in the planning rubric.

Step 2: Plan and storyboard

Read: references/step-2-plan.md

Write <output-dir>/coco-ads-plan.md. Answer the planning rubric, commit to a creative angle, and write the beat-by-beat storyboard (scenes, text, timing, transitions, SFX cues). Include a compact Music cue guidance section when music is selected.

Gate: <output-dir>/coco-ads-plan.md exists with a full storyboard; scene durations sum to 15–25 seconds.

Step 3: Hand off to HyperFrames

Read: the installed HyperFrames composition skills (npx hyperframes skills if absent), then references/step-3-compose.md and references/audio.md.

Write <output-dir>/composition-brief.md, then build the composition in <output-dir>/composition/. /coco-ads owns product angle, source material, storyboard, tone, format, audio selection, and delivery; HyperFrames owns the concrete composition structure, animation mechanics, and render workflow.

Gate: npx hyperframes lint passes with zero errors inside <output-dir>/composition/.

Step 4: Validate, render, and deliver

Read: references/step-4-deliver.md

Validate (npx hyperframes validate + inspect), render to <output-dir>/brag.mp4, and write <output-dir>/share-copy.txt.

Gate: the rendered MP4 exists and share copy is written.

Tone system

Seven presets ship with /coco-ads. Each changes scripting energy, pacing, typography personality, and transition style. Presets are defaults, not limits — always allow a freeform creative direction to refine or override.

Full definitions: references/tones.md

| Tone | Energy | One-liner |

|---|---|---|

| default | Playful, clean, postable | The good-vibes default |

| polished | Serious, elegant | For projects that are not jokes |

| yc-parody | Deadpan startup energy | Fake seriousness applied to absurd projects |

| chaotic | Fast, loud, aggressive | Over-the-top and unhinged |

| deadpan | Calm, dry, understated | The joke is that nothing is a joke |

| cinematic | Dramatic, trailer-scale | Big motion, bigger claims |

| app-store | Smooth, feature-card clean | Corporate but not boring |

Creative laws

These apply to every video regardless of tone.

Short. 15–25 seconds. Not one second more without a reason.

Readable. Keep the pace high through motion and cuts, never by flashing text. Every line a viewer must read holds long enough to read it (short label ~0.8s settled; a sentence ~0.3s per word). Fast-in, then hold — never fast-in, then gone.

Specific. The video must feel like it was made for this exact project, not any project.

Show the thing. At least one scene must display actual UI, copy, or a key visual from the product. No abstract filler.

No generic SaaS language. "Streamline your workflow" is banned. Use the project's actual copy and claims.

The hook is everything. The first 2 seconds decide whether someone keeps watching. Plan the hook before anything else.

Funny earns its place. Humor should come from the project's absurdity, not from trying to be funny.

Pattern:

Hook (2-3s) → Reveal (2-4s) → 2-3 sharp highlights (5-12s) → Punchline/outro (2-4s)

Adapt this. The pattern is a starting shape, not a template.
