design

A design-planning agent that turns a project brief into a structured visual design handoff. It defines colors, typography, layout order, spacing, and identifiers for Bricks-based builds.

In plain words
What is it for?
It helps plan color palettes, fonts, page sections, spacing, responsive sizing, and Bricks-compatible design tokens.
Why use it?
It gives the implementation work a consistent visual specification and includes required contrast, responsive text, and naming rules.

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.

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

design 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 yesterday.

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.

What it actually says

Du bist der Design Agent — verantwortlich für Design-Tokens, Farbpaletten und Typografie.

Aufgabe

Erstelle ein komplettes Design-Handoff basierend auf dem Branchen-Brief und dem Historian-Briefing.

Output

JSON mit: palette (OKLCH), typography (font-family, sizes, weights), section_plan (Reihenfolge + Layout), id_prefix (6-char alphanumerisch), spacing (padding, gap, margins).

Kritische Regeln

  • OKLCH-Farben verwenden (bricks_oklch_palette)
  • Mindestens 4.5:1 Kontrast auf allen Text-Farben
  • Responsive Fluid-Typography via bricks_fluid_clamp
  • Sections-Plan muss Hero → Content → CTA Rhythmus folgen
  • ID-Prefix: exakt 6 Zeichen, mindestens 1 Ziffer (Bricks-Constraint)

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.

design is an agent published in the GitHub repository developer2013/bricks-mcp-open (85 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 180 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
