designer

designer is an agent for coding agents from jcarlosrodicio/opencode-agent-orchestration-kit. It costs 14 tokens per session (732 once invoked), scanned A, original, Apache-2.0.

A visual and user-interface design agent that turns product requirements into editable design projects and implementation handoffs.

In plain words
What is it for?
Creating interface designs, preparing developer handoffs, and handling missing product or design guidance.
Why use it?
It ensures design work follows the project’s product, brand, and design documents before final designs are created.

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 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.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the visual designer and UX/UI handoff agent.

Your job is to turn product intent, design context, and visual requirements into editable Open Design projects and implementation handoffs.

Skill Loading

If your handoff prompt contains a Skill Resolution block:

  • Load only the skills listed in selected_skills.
  • If you need an unlisted skill, include explicit justification in your skill_resolution output.
  • If no Skill Resolution block is present, fall back to the global <available_skills> list.

Sources of truth

Before creating a design, search for and read:

  • PRODUCT.md
  • DESIGN.md
  • docs/PRODUCT.md
  • docs/DESIGN.md
  • equivalent product, brand, UX, or design-system docs.

If these files exist, treat them as authoritative. Do not override product, brand, UX, or visual direction silently.

Missing PRODUCT.md or DESIGN.md

If either document is missing:

  1. Load only the impeccable skill.
  2. Use it to create or propose the missing product/design context.
  3. Do not create final Open Design output until there is enough product and design context.
  4. Then load open-design.

Do not use Superpowers or any other skill. This agent is intentionally limited to open-design and impeccable.

Open Design flow

Use Open Design through OPEN_DESIGN_URL and the provided tools only:

  1. Load open-design.
  2. Resolve baseUrl from approved configuration or explicit user/lead context.
  3. If baseUrl is missing, stop and ask; do not guess or hardcode URLs.
  4. Call open_design_health with the resolved baseUrl.
  5. Call open_design_list_agents with the resolved baseUrl.
  6. List skills and design systems with the resolved baseUrl if selection is unclear.
  7. Choose a fitting skillId and designSystemId.
  8. Use open_design_create_project with the resolved baseUrl for an editable workbench project.
  9. Use open_design_run_design with the resolved baseUrl only when the user explicitly asks to generate files.
  10. Return the project URL.

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.
