A skill that turns a project's website code into a short launch video using Hyperframes. It can work directly from the project without a live website address or screenshots.

Use it to make a shareable launch video from a project, including optional choices such as a title, music setting, or voice narration.

It gives you a way to present what you built without first collecting screenshots or preparing a separate video source.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00071	$0.02187
Opus 5.5	$0.00028	$0.00875
Sonnet 5.5	$0.00014	$0.00437
Haiku 4.5	$0.00007	$0.00219

Security

Grade A, and why

brag scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/brag

You built it. Now let's brag about it.

Invocation dispatch (must happen first)

Model check. If you are Claude Opus 5.5 and the invocation doesn't ask for the full workflow (--full, "use the full brag") or for voiceover (--voice, which brag-slim doesn't do), switch to brag-slim: read <skill-dir>/slim.md (the /brag-slim skill, bundled here) and follow it for the rest of this run instead of this file. Pass along the user's input, and pass any other options (--no-music, --title, …) as plain-language direction. Tell the user in one line first, e.g. "You're on Opus 5.5, so I'm using /brag-slim: I build the whole video myself. Say 'use the full brag' to switch back." If you are any other model, or can't tell which model you are, skip this check.

Before inspecting the project, parse the complete /brag invocation. If the invocation contains --voice, set voice.enabled = true. Enable narration only for that run. Do not enable narration automatically and do not fall back to the normal no-voice workflow.

/brag turns the current project website or app into a short, polished, shareable launch video using Hyperframes. It is narrow, opinionated, and fun.

What this skill does

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

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

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
