ai-workspace: Skill for Codex

.agents/skills/dev-env/SKILL.md

dev-env is a skill for Codex from ZhuoZhuoCrayon/ai-workspace. It costs 151 tokens per session (518 once invoked), scanned A, original, MIT.

A local development-environment helper for Go, Node.js, and Python projects. It switches language versions and addresses missing tools, broken dependencies, virtual environments, and environment-related build or test failures.

In plain words
What is it for?
Use it to prepare or repair a local Go, Node.js, or Python workspace, change versions with gvm, nvm, or uv, and investigate setup failures during compilation, testing, or checks.
Why use it?
It helps when a project needs a different runtime version or when setup problems are mistaken for code problems. It checks the versions and tools declared by files such as go.mod, .nvmrc, pyproject.toml, or uv.lock.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is ZhuoZhuoCrayon/ai-workspace's own configuration. It tells Codex how to work on ai-workspace itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-workspace configures →

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

dev-env 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 8d 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

Dev Env

0x01 核心

  • 任何项目下都假定 gvmnvmuv 已装。
  • gvmnvmsource 进来的 shell 函数,which 查不到是正常现象,不要据此判定未安装。
  • 先跑项目命令,遇到环境类失败再读对应 reference。
  • 系统默认版本和项目声明版本不一致(如 go.mod1.23、系统是 1.20)就是本 skill 的场景:先用版本管理器切到目标版本,不要判定环境不可用或跳过、假装跳过编译、测试。
  • 版本管理器加载不上或行为异常时,再直连它装好的二进制兜底(见各 reference)。

What ships with it

4 files 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.

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.
