design

design is a command for coding agents from aneja5/forge-skills. It costs 23 tokens per session (172 once invoked), scanned A, original, MIT.

A design-system planning command for defining shared visual rules and reusable interface components. Design tokens are named values for things such as colors, spacing, type sizes, and corner shapes.

In plain words
What is it for?
Use it to document brand rules, semantic tokens, scales, breakpoints, component states, dark-mode mappings, a visual gallery, composition rules, and common design mistakes.
Why use it?
It helps keep screens consistent and makes light mode, dark mode, responsive layouts, and interaction states explicit instead of leaving them to individual implementation decisions.

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 4d 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.

What it actually says

Invoke the forge-skills:design-system skill.

Define brand foundation (voice, accent, neutral scale, density). Write the semantic token layer — components reference semantic tokens only, never raw hex. Dark mode is a remapping, not a rewrite. Define scales — typography (6-7 sizes), spacing (4px/8px grid), radius, motion, breakpoints. For every interactive primitive, define all 6 states: default, hover, active, focus-visible, disabled, loading. Plus error for inputs. Build the gallery in light + dark. Write composition rules + anti-patterns.

After writing: "Design system written to .forge/design-system.md. Pair with /interaction and /a11y."

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.
