Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02410 |
| Opus 5.5 | $0.00028 | $0.00964 |
| Sonnet 5.5 | $0.00014 | $0.00482 |
| Haiku 4.5 | $0.00007 | $0.00241 |
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 17d 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.
This is a copy
88% identical to brag — 36 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 212 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 |
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
