design-system-engineer

design-system-engineer is an agent for coding agents from josstei/maestro-orchestrate. It costs 254 tokens per session (372 once invoked), scanned A, original, Apache-2.0.

A design-system engineering helper for creating shared visual rules and reusable user-interface components.

In plain words
What is it for?
Use it to create design tokens, define component interfaces, plan theming, organize CSS, and establish visual regression testing.
Why use it?
It helps keep styles and component behavior consistent across an application while making themes and visual testing easier to manage.

Install

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.

agentmods
npx agentmods add agents/josstei/maestro-orchestrate/design-system-engineer
Clone the repo
git clone --depth 1 https://github.com/josstei/maestro-orchestrate

Or install claude, the plugin that ships this one along with the rest of its 17 agents, 1 MCP server.

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-system-engineer 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 5d 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.

Changes

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.
