OpenDesign is an open-source, local-first desktop app that lets coding agents create prototypes, dashboards, slide decks, images, video, and design systems as exportable files. It is used by people working with agent runtimes such as Claude Code, Codex, Cursor, and DeepSeek Harness. The catalogue add-ons extend the OpenDesign workflow with skills, instructions, commands, and plugins.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.00281 |
| Opus 5 | $0.00010 | $0.00140 |
| Sonnet 5 | $0.00004 | $0.00056 |
| Haiku 4.5 | $0.00002 | $0.00028 |
Grade A, and why
direction-picker 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
Direction picker
Generative work benefits from explicit divergence before it converges.
This atom defines how to present 3–5 distinct visual / structural / tonal
directions when the user explicitly asks to see or compare direction options.
Only in that case, emit one inline <question-form> with a direction-cards
question. The submitted choice returns as the next user message.
The presence of this atom or the plan stage does not trigger a picker. Do not
emit direction cards proactively. When the user has not explicitly requested
options, infer a fitting direction from the brief, active design system, and
known context, then continue.
Convergence
When a picker was explicitly requested, the atom completes when the submitted form answer contains a direction id. The agent's next turn must lock onto that direction — backtracking forces a fresh devloop iteration of the picker stage.
Anti-patterns the prompt fragment forbids
- More than 5 directions on one turn (decision fatigue).
- Two directions that are minor variations of each other.
- Locking the user into a single direction with cosmetic alternates (every direction must be a defensible standalone bet).
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

direction-picker is a skill published in the GitHub repository nexu-io/open-design (94,527 stars, last pushed today), licensed Apache-2.0. It adds 20 tokens to every session and 281 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
