  • Media & Creative work in your project
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Brag Slim is an agent skill from NousResearch/hermes-agent. Launch video from a project or URL, upstream-maintained.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative. The repository describes itself as: The agent that grows with you. The licence is MIT.

When your agent uses it

  • Media & Creative work in your project

Example prompts

  • “/brag-slim”

What it can do on your machine

Read from SKILL.md and the folder at commit dce1e9b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Brag Slim loads about 497 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 213 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~17
When it runs · the whole SKILL.md, loaded when a task matches
~497

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Brag Slim (upstream-maintained)

Catalog stub. This entry is maintained upstream at latent-spaces/brag: the project ships /brag-slim as a single SKILL.md under skills/brag-slim/. hermes skills install official/creative/brag-slim pulls the current file live from that repo (quarantined and scanned like any hub install) — this directory holds only the catalog metadata, so the vendored copy can never go stale.

/brag-slim is the lean /brag, written for Claude Opus 5.5: no Hyperframes, no bundled assets. The model builds the whole launch video itself (story, visuals, music, sound effects, mix and render) with the tools already on the machine. It takes the current project directory or a website URL, reuses the source's real UI, fonts and assets instead of redrawing them, and writes brag-output/ with the plan, the rendered video and share copy. Options: --tone, --format landscape|vertical|square, --duration.

brag adds the classic Hyperframes workflow, the bundled soundtrack and SFX, and --voice narration (see its prerequisites). It includes this skill and hands off to it on Opus 5.5.

Prerequisites

  • No fixed toolchain: the model builds with whatever is installed. In practice that means FFmpeg for the audio mix and encode, plus a headless browser (Node with Playwright or Puppeteer, or Chrome) to draw frames from HTML and to capture websites that render their page with JavaScript.
