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 | $0.04007 | $0.04007 |
| Opus 5.5 | $0.01603 | $0.01603 |
| Sonnet 5.5 | $0.00801 | $0.00801 |
| Haiku 4.5 | $0.00401 | $0.00401 |
Grade C, and why
open-codesign AGENTS.md scanned grade C with 2 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 7d 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.

AGENTS.md - Open CoDesign
Instructions for Codex and other AI coding agents working in this repository. Read this before making changes.
CLAUDE.md may lag behind the current plan. For Codex work, treat this file as the public source of truth. If local internal docs such as docs/VISION.md, docs/PRINCIPLES.md, or docs/v0.2-plan.md exist, use them as additional context; if they are missing, do not block public-contributor work on them.
What This Project Is
Open CoDesign is an open-source desktop design agent. It turns prompts, local files, skills, scaffolds, brand systems, and model output into design artifacts on the user's laptop.
The v0.2 direction is no longer a single-prompt generator. Each design is a long-running pi session with a real workspace. The agent can read and edit files, run permissioned commands, ask structured questions, preview artifacts, expose tweak controls, generate images when the configured model supports it, and produce DESIGN.md design-system artifacts.
The original inspiration was Claude Design. The product boundary is now clearer: Open CoDesign borrows proven coding-agent mechanics, then adds design-specific tools and a local-first workspace model.
Product model: a Design owns a workspace. The agent edits design source files in that workspace; the preview runtime turns those sources into a rendered web document; exporters turn the rendered/source document into standard outputs such as HTML, PDF, PPTX, ZIP, or Markdown. In v0.2 the default source entry is App.jsx; index.html is reserved for standalone exports or legacy workspace files.
docs/ is gitignored. Maintainers may have internal plans, handoffs, and research locally; public contributors may not. Do not cite docs/** in public PR review comments unless the file exists in the public checkout.
Hard Constraints
These are project commitments, not preferences:
- No bundled model runtimes. Do not ship Ollama, llama.cpp, Python, browser binaries, or model weights inside the installer. Use system installs or lazy-download with user-visible consent.
- BYOK only. No hosted account, proxied API, or telemetry by default. User credentials stay in human-readable local config.
- Local-first storage. v0.2 uses pi JSONL sessions plus real workspace files. Existing v0.1 SQLite data may be migrated, but do not add new SQLite tables for sessions, chat history, comments, snapshots, or design files.
- Every design has a workspace. No sealed/open split in v0.2. The workspace filesystem is the source of truth for artifacts and assets.
- Shipped app/runtime dependencies, bundled assets, scaffolds, skills, brand refs, and copied code must be MIT-compatible permissive. Reject GPL, AGPL, SSPL, proprietary deps, and unclear copied assets in anything that is bundled, linked, imported by app code, or distributed to users. Workflow-only CI/release tools may use copyleft licenses when they are not vendored, bundled, linked, or copied into the product; document the reason and keep their outputs limited to ordinary metadata or manifests.
- Lazy-load heavy features. PPTX export, web capture, scaffolds, skills, brand refs, and image generation must load on demand rather than at app start.
- Reuse pi primitives first.
pi-coding-agentowns sessions, built-in tools, bash execution, event streaming, model registry, provider registration, and capability data unless a design-specific need proves otherwise. - Brand values are data, not model memory. Use
DESIGN.md, user files, official CSS/SVG/screenshots, or brand URLs. Do not invent brand hex values from memory. - PRs should stay compatible, upgradeable, lean, and elegant. If
docs/PRINCIPLES.mdis present, use its Principles 5b wording as the detailed checklist.
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 AGENTS.md is an instructions file published in the GitHub repository OpenCoworkAI/open-codesign (8,129 stars, last pushed yesterday), licensed MIT. It adds 4,007 tokens to every session, about $0.0160 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
