URDF-Studio AGENTS.md

A compatibility entry for the URDF-Studio project, where URDF is a standard format for describing robot models; its main instructions are kept in CLAUDE.md.

In plain words
What is it for?
It is for directing code organization, robot-file format detection, viewer code, workspace synchronization, local server access, HTTPS setup, and browser-process cleanup.
Why use it?
It helps agents use the project’s current rules and avoid outdated file locations, duplicated logic, unsafe browser cleanup, or incorrect development-server settings.

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

URDF-Studio AGENTS.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 2d 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

URDF Studio Agent Guide

内容已合并到 CLAUDE.md。本文件保留为兼容入口,所有 agent 上下文请直接读 CLAUDE.md

同步提醒:

  • 更新 agent 规则时以 CLAUDE.md 为主,必要时同步本兼容入口。
  • scripts/ 已统一为 build/generate/test/tools/release/ 五类;新增或移动脚本时不要恢复旧目录名,具体结构以 CLAUDE.mdscripts/ 目录结构 为准。
  • 机器人源文件格式检测以 src/core/parsers/format_detection.ts 为 canonical source;app / features/file-io 只保留 workflow wrapper,不重复实现格式判断。
  • viewer backend 生命周期归 src/features/urdf-viewer/renderers/src/shared/components/3d/renderers/ 只放纯 mesh renderer 组件与 Collada scene helpers。
  • workspace/source 同步策略优先放 src/app/hooks/workspace-source-sync/workspace-mutations/ 子模块,避免继续堆大 useWorkspaceSourceSync.ts / workspaceSourceSyncUtils.ts
  • npm run dev 默认绑定 127.0.0.1;远程开发端口转发、容器或局域网访问需显式使用 URDF_STUDIO_DEV_HOST=0.0.0.0 npm run dev;局域网 HTTPS 模式(USD WASM 需要安全上下文)使用 URDF_STUDIO_DEV_HTTPS=true npm run dev,具体说明以 CLAUDE.md开发服务器访问 为准。
  • 浏览器验证、Playwright/Puppeteer、浏览器回归脚本结束后,必须按 CLAUDE.md 清理残留浏览器进程;优先运行 node test/usd-viewer/scripts/cleanup-headless.cjs,不要使用会误杀用户浏览器的宽泛 pkill chrome / killall chrome
Changes

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.
