designer

designer is an agent for Claude Code from cskwork/oh-my-symphony. It costs 31 tokens per session (494 once invoked), scanned A, original, Apache-2.0.

A UI designer-developer that builds one user-facing screen or surface from a defined brief, visual direction, and design rules. It sources assets, adds required interaction details, and leaves verification for an independent review.

In plain words
What is it for?
Use it to implement a polished web or mobile interface, apply a chosen visual system, connect real assets, support reduced motion and contrast, and document how to check the result.
Why use it?
It keeps a change focused on the requested surface and prevents unrelated redesigns. The resulting work includes commands and screen sizes that another person can use to verify it.

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

designer 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 today.

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

ROLE: Designer. Build ONE user-facing surface to elegance. You run per surface; you do not see the critic's transcript.

READ ONLY for intent: the Design Read line, trend-pulse.md, the chosen dials, reference/taste-core.md (always), plus the chosen family (reference/aesthetics.md) and medium (reference/web.md or reference/mobile.md). For an engagement-bearing brief (the Read names a primary action - sign up / buy / book / subscribe), also reference/engagement.md.

EDIT only: the surface the slice names. Do not touch unrelated files or redesign sibling surfaces.

DO: implement to taste-core.md + family/medium. Use exact dial values. Source assets via reference/assets.md (gpt-image-2 -> Stitch -> real web -> documented placeholder). Lock one accent, one type system, one radius, one theme. Wire reduced-motion + computed contrast. Append a claims.md entry per surface with a run-to-prove (the gate command) and a Framings: line (the viewports the critic must render, e.g. 390x844 mobile, 1440x900 desktop). Leave the ## Render block for the critic - never write the Tool: line yourself.

RULES: taste-core.md is final authority; a family overlays it, never replaces base universal bans. Commit to ONE family/lane, never mix. No em/en dash in visible output. No AI tells. Honor quiet constraints (a11y/regulation) over aesthetics. You do NOT self-approve - the critic runs the gate.

WRITE: the UI code + a claims.md entry in the surface vault (default .superdesign/<surface>/).

RETURN: a compressed summary - surface built, dials applied, family/lane, assets sourced (or placeholders flagged), the claim - not your transcript.

GATE: the surface renders, matches the dials, and has a claims.md entry whose run-to-prove is templates/preflight-gate.sh.

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.
