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 | $0.00121 | $0.02139 |
| Opus 5.5 | $0.00048 | $0.00856 |
| Sonnet 5.5 | $0.00024 | $0.00428 |
| Haiku 4.5 | $0.00012 | $0.00214 |
Grade A, and why
brag-slim 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 15d 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
89% identical to brag-slim — 38 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/brag-slim
You built it. Now brag. You make the whole video yourself — story, visuals, audio, render — with whatever tools are on the machine.
Whatever the tone, it should feel like a modern, slick, polished launch video: nothing on screen or in the soundtrack that doesn't earn its place.
Usage: /brag-slim [input] [options]. Options (flags or plain language):
| Option | Default |
|---|---|
--tone <preset or freeform> |
inferred; default if nothing clearly fits |
--format landscape|vertical|square |
landscape (1920×1080; vertical 1080×1920, square 1080×1080), 30fps |
--duration <s> |
about 20s |
Write the deliverables to brag-output/ in the current directory (timestamped brag-output-YYYY-MM-DD-HHmmss/ if it already exists). Keep every intermediate file (frames, downloads, scripts, stems) in a work/ subfolder inside it.
1. Inspect
First decide what the input is, then gather material from it. Only the source changes; everything from the questions below onward is the same for every input.
| Input | How to recognize it | Where the material comes from |
|---|---|---|
| Project | No input given, and the current directory is a project | The code |
| Website | An http(s):// URL, or a bare domain like example.com |
The live site |
If the input matches no type, or there's no input and the current directory isn't a project, ask the user what to brag about.
Project
Read the code: the main page, styles (exact colors and fonts), README, routes and key components. The best material is the product in use — find its 2–3 beats: entry → key action → result.
You have the source, so use it directly: import or render the project's real components, stylesheets, fonts, images and animations in the video instead of rebuilding them.
Website
Get the site as a visitor sees it. Many sites build their page with JavaScript, so a plain download can come back as an almost empty shell. If it does, load the page in a headless browser to get the rendered result. Dismiss cookie banners and other overlays, and scroll section by section, since content that animates in on scroll stays blank in a single full-page capture.
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.
