Parsing the invocation

The user may invoke with natural language or flags:

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

Parse these options:

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
`--voice`	flag	narration off

Voice is opt-in. If --voice is present, use Kokoro via Hyperframes and do not add any provider-selection logic. The voice workflow is intentionally single-provider in this PR.

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", "museum exhibit", or "overproduced mobile game ad".

When the user gives freeform tone direction, map it to the nearest preset for pacing and structure, but preserve the user's direction in the plan and composition brief.

Narration guidance

When --voice is enabled, write narration that complements the visuals, does not simply read visible text, matches scene pacing, sounds natural and conversational, and moves smoothly between scenes. Keep the script concise and specific to the product so the voice feels like part of the edit rather than a separate narration track.

Output directory

By default, output goes to brag-output/. To avoid overwriting previous runs, use a timestamped directory:

brag-output-2026-05-04-143022/

Use a timestamp when:

The user explicitly asks for a new run without overriding previous results
A brag-output/ directory already exists in the project

Generate the timestamp at the start of the run (YYYY-MM-DD-HHmmss) and use it consistently for all output paths in that run: plan, brief, composition, render, and share copy.

Step 1: Inspect the project

Read: references/step-1-inspect.md

Scan the project directory and extract the information needed to plan the brag video.

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

Step 2: Plan and storyboard

Read: references/step-2-plan.md

Write <output-dir>/brag-plan.md (where <output-dir> is brag-output/ or the timestamped variant chosen above). Answer the planning rubric. Commit to a creative angle. Write the beat-by-beat storyboard including scenes, text, timing, transitions, and SFX cues.

When music is selected, include a compact Music cue guidance section: read the bundled track's cue preset from assets/music/cues/ if present, otherwise note cues will be detected at composition time (any track now supports beat sync — see references/audio.md). Cue metadata is optional timing guidance only: story, readability, pacing, and product clarity stay primary.

Gate: <output-dir>/brag-plan.md exists with a full storyboard. Scene durations sum to 15–25 seconds.

Step 3: Hand off to Hyperframes

Read: The Hyperframes domain skills — hyperframes-core, hyperframes-animation, hyperframes-creative, hyperframes-keyframes, hyperframes-cli. /brag is its own workflow: do not enter the hyperframes entry-point intent interview or route into its generic promo / launch-video workflow. Read: references/step-3-compose.md Read: references/audio.md

Write the composition brief and use Hyperframes to create the video implementation in <output-dir>/composition/.

/brag owns the product angle, source material, storyboard, tone, format, audio selection, music cue guidance, and delivery expectations. Hyperframes owns the concrete composition structure, exact animation timing, animation mechanics, runtime choices, linting rules, and render workflow.

Gate: npx hyperframes check passes with zero errors inside <output-dir>/composition/ (the single browser gate before render — see hyperframes-cli for what it audits).

Step 4: Validate, render, and deliver

Read: references/step-4-deliver.md

Validate, preview, render to <output-dir>/brag.mp4, pick the best poster frame into <output-dir>/brag.jpg, bake that poster as the video's frame 0 so it's the idle thumbnail everywhere, and write <output-dir>/share-copy.txt.

Gate: <output-dir>/brag.mp4 exists. A best-frame poster <output-dir>/brag.jpg is picked (not an arbitrary frame) and baked as frame 0 of brag.mp4. Share copy is written.

Tone system

Seven tone presets ship with /brag. Each changes scripting energy, pacing, typography personality, and transition style. Presets are defaults, not limits.

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

Always allow a freeform creative direction to refine or override the preset.

Creative laws

These apply to every brag 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 determine 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. Not every project needs exactly 3 highlights. The pattern is a starting shape, not a template.
