What it does

Skill Add is an agent skill from iZiTTMarvin/Nova-agent. 从 URL 或 zip 安装第三方技能到 ~/.nova/skills 或项目 .nova/skills

Its SKILL.md is about 280 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 最适合新手、懒人、业余开发者使用的本地桌面 Agent，长会话不丢上下文，一句话跑完全流程，无需如何门槛即可完成高质量的开发. The licence is MIT.

Example prompts

  • “/skill-add”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. 确认 zip 路径存在（read 或 bash 检查）
  2. 解压到临时目录，查找 SKILL.md（通常在 /SKILL.md）
  3. 解析 frontmatter，校验 name 与 description
  4. 目标目录
  5. 复制整个技能目录（含附属文件）到目标路径
  6. 若同名已存在，询问是否覆盖

What it can do on your machine

Read from SKILL.md and the folder at commit 216466e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skill Add loads about 277 tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~16
When it runs · the whole SKILL.md, loaded when a task matches
~277

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

安装技能（skill-add）

你正在执行 skill-add 技能，帮助用户从 zip 包 或 URL 安装技能。

工作区

  • 路径：<%= workspacePath %>

用户参数

${arguments}

若用户未提供参数，请询问：zip 本地路径、或 https:// 下载地址，以及安装位置（global | project）。

安装流程

方式 A：本地 zip（推荐）
  1. 确认 zip 路径存在（read 或 bash 检查）
  2. 解压到临时目录，查找 SKILL.md（通常在 <skill-name>/SKILL.md）
  3. 解析 frontmatter，校验 name 与 description
  4. 目标目录：
    • global：~/.nova/skills/<name>/
    • project：.nova/skills/<name>/
  5. 复制整个技能目录（含附属文件）到目标路径
  6. 若同名已存在，询问是否覆盖
方式 B：URL 下载
  1. 仅接受 https:// 链接
  2. 下载到临时目录（超时 30s）
  3. 按方式 A 第 2–6 步处理
方式 C：设置页导入（UI）

提示用户也可在 设置 → 技能 → 导入 中拖拽 zip（若 UI 已启用）。

安装后验证

  1. 列出 SKILL.md 的 name 与 description
  2. 建议用户输入 /技能名 试用
  3. 若解析有 warnings，逐条说明

安全与约束

  • 不要执行 zip 内未知脚本；仅复制 Markdown 与明确附属文件。
  • 不修改用户 Claude Code 源目录（~/.claude/skills）；第三方 Claude 技能由应用设置开关只读挂载。
  • 安装失败时保留错误信息，不留下半成品目录（或清理空目录）。

环境提示

安装全局技能时，路径基于用户主目录下的 .nova/skills/。项目级技能仅对当前工作区可见。
