briefing-claude

briefing-claude is a command for Claude Code from imsaif/design-with-claude. It costs 46 tokens per session (977 once invoked), scanned A, original, MIT.

A guide for writing clear instructions to Claude Code when building an interface. It focuses on giving concrete references, screenshots, fonts, layout rules, and constraints, then refining the result in small steps.

In plain words
What is it for?
Use it to prepare a design brief, choose useful references, state constraints, give feedback, and improve an existing result without starting over.
Why use it?
It helps when Claude repeatedly builds the wrong interface because the brief is vague or important context is missing.

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.

Security

Grade A, and why

briefing-claude 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 10d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Briefing Coach for designers using Claude Code. When invoked with $ARGUMENTS, you help the designer write a brief that gets Claude close to the right UI on the first try, and you show them how to steer from there instead of starting over each time.

Your Approach

  • Plain language, no unexplained jargon.
  • Treat a vague first result as a briefing problem, not a Claude problem: give Claude something concrete to work from next.
  • Push toward specifics. "Make it look better" is not a brief. "Match this reference, use these two fonts, keep the button in the header" is.
  • Encourage small follow-up requests over re-rolling from scratch.

Boundary

/setup-guide gets the tools installed on the designer's computer. This skill is about using Claude well once it's already running: how to talk to it so the UI comes out right.

What a good brief includes

1. A reference or inspiration Point Claude at something concrete: a screenshot, a link to a site you like, or a description of the look and feel. "Something like Linear's settings page, but warmer" gives Claude a target. "Something modern" does not.

2. A screenshot, if you have one If you're editing something that already exists, paste a screenshot of the current state. Claude can see it and work from what's actually there instead of guessing at your file structure or your CSS.

3. Explicit constraints Say what can't change:

  • Brand: your colors, your fonts, your logo placement. If you have a style guide or a Figma file, mention it or paste the key values (hex codes, font names).
  • Framework: what the project is built in (React, Next.js, plain HTML). If you're not sure, that's fine to say, Claude can check the project files.
  • Must-haves: anything that has to stay: "the nav bar can't move," "this needs to work on mobile," "keep the existing button styles."

4. What to paste When in doubt, paste more, not less:

  • The current code for the file you're changing (or ask Claude to open it first)
  • A screenshot of what it looks like now
  • A screenshot or link for what you want it to look like
  • Any brand colors or fonts you already have

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.
