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

open-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 6d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Open Design Skill

Use this skill for visual design, UX/UI, prototypes, product visuals, landing pages, dashboards, pricing pages, docs pages, mobile screens, onboarding, decks, and design handoff.

OPEN_DESIGN_URL

The workbench URL is configured with OPEN_DESIGN_URL.

Valid examples:

  • https://open-design.example.com
  • http://192.168.1.50:7456

Invalid examples:

  • https://open-design.example.com/projects/my-project
  • https://open-design.example.com/projects/my-project/files/index.html

Resolve the tool baseUrl from approved configuration or explicit user/lead-provided context before calling Open Design tools. Do not invent, guess, or hardcode a URL. If no approved baseUrl is available, stop and ask for the missing configuration/context instead of trying a fallback.

PRODUCT.md and DESIGN.md

Before using Open Design, inspect the repository for PRODUCT.md and DESIGN.md or equivalent docs.

If present, they are authoritative. If one or both are missing, the designer should use the optional impeccable skill first to create or propose missing context.

Tools

Use only the Open Design tools:

  • open_design_health
  • open_design_list_agents
  • open_design_list_skills
  • open_design_list_design_systems
  • open_design_create_project
  • open_design_run_design

Pass the resolved baseUrl to every Open Design tool call, including health, list, create, and run calls.

Modes

Workbench

Default mode. Use open_design_create_project to create an editable project and return its URL.

Direct generation

Use only when the user explicitly asks to generate the design. Call open_design_run_design and return generated files when available.

Handoff

When no project is needed, return a design brief, Open Design prompt, implementation notes, risks, assumptions, and visual acceptance criteria.

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.
