Open CoDesign is a desktop design tool that turns prompts into artifacts such as prototypes, slides, and PDFs using models chosen by the user. It is for people who want to create designs locally with their own model access and laptop. The catalogue instructions support workflows for using the application.

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 | $0.01789 | $0.01789 |
| Opus 5.5 | $0.00716 | $0.00716 |
| Sonnet 5.5 | $0.00358 | $0.00358 |
| Haiku 4.5 | $0.00179 | $0.00179 |
Grade A, and why
open-codesign CLAUDE.md 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 2mo 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What this project is
open-codesign is an Electron desktop app that turns natural-language prompts into design artifacts (HTML prototypes, PDFs, PPTX decks, marketing assets). It's the open-source counterpart to Anthropic's Claude Design, with multi-provider model support via pi-ai and a local-first storage model.
The full vision and locked decisions live in docs/VISION.md when the internal docs are present locally. Public checkouts may not have docs/; in that case use AGENTS.md, public issues/PRs, and README context instead of blocking.
Note:
docs/is gitignored — internal team materials (research, roadmaps, handoffs) live there but are not part of the public repo. Clone contributors will not have this directory; team members will find it present locally after cloning and copying the internal docs back.
Hard constraints (do not violate)
These are project-level commitments, not preferences:
- No bundled model runtimes. No Ollama, llama.cpp, Python, or browser binaries shipped in the installer. Use system installs or lazy-download on demand.
- BYOK only. No proxied API calls, no cloud account, no telemetry by default. User credentials stay in
~/.config/open-codesign/config.toml(plaintext, file mode 0600 — matching Claude Code / Codex / gh CLI conventions). - Local-first storage. v0.2 design state is file/session based and local-first. Do not add new SQLite-backed session/design feature state.
- Permissive shipped dependencies. Shipped app/runtime dependencies, bundled assets, scaffolds, skills, brand refs, and copied code must be MIT-compatible permissive. Workflow-only CI/release tools may use copyleft licenses when they are not vendored, bundled, linked, or copied into the product; document the reason.
- Lazy-load heavy features. PPTX export, web capture, codebase scan, etc. must dynamic-import on first use, not on app start.
- Compatibility, upgradeability, no bloat, elegance — the four PRINCIPLES §5b checks. Every PR description must mark all four green.
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.

open-codesign CLAUDE.md is an instructions file published in the GitHub repository OpenCoworkAI/open-codesign (8,129 stars, last pushed yesterday), licensed MIT. It adds 1,789 tokens to every session, about $0.0072 per session on Opus 5.5. 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 2026-08-30.
