安装

选择你的客户端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "caveman-skill": {
      "command": "claude",
      "args": [
        "plugin",
        "marketplace",
        "add",
        "JuliusBrussee/caveman"
      ],
      "_inferred": false
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "caveman-skill": {
      "command": "claude",
      "args": [
        "plugin",
        "marketplace",
        "add",
        "JuliusBrussee/caveman"
      ],
      "_inferred": false
    }
  }
}

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "caveman-skill": {
      "command": "claude",
      "args": [
        "plugin",
        "marketplace",
        "add",
        "JuliusBrussee/caveman"
      ],
      "_inferred": false
    }
  }
}

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "caveman-skill": {
      "command": "claude",
      "args": [
        "plugin",
        "marketplace",
        "add",
        "JuliusBrussee/caveman"
      ],
      "_inferred": false
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "caveman-skill",
      "command": "claude",
      "args": [
        "plugin",
        "marketplace",
        "add",
        "JuliusBrussee/caveman"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "caveman-skill": {
      "command": {
        "path": "claude",
        "args": [
          "plugin",
          "marketplace",
          "add",
          "JuliusBrussee/caveman"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add caveman-skill -- claude plugin marketplace add JuliusBrussee/caveman

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。

使用场景

实战用法： Caveman

Get crisp one-line commit messages for every patch

👤 Anyone tired of 8-paragraph AI-written commits ⏱ ~5 min beginner

何时使用： Claude writes a commit message, and it's a novel. You want it to say 'fix: off-by-one in pagination' and stop.

前置条件

Caveman plugin installed — claude plugin marketplace add JuliusBrussee/caveman && claude plugin install caveman@caveman

步骤

Commit with caveman-commit

/caveman-commit — write a commit message for the staged changes.✓ 已复制

→ One-line conventional commit; no body unless genuinely needed
Ship a branch of small commits

For the 4 staged files, use /caveman-commit per file — atomic commits, one line each.✓ 已复制

→ git log shows 4 short commits

结果： Readable git log; bisect-friendly commits.

注意事项

Lost nuance when a message should be longer (e.g. breaking changes) — Override per-commit: 'write the full version, not caveman, this is a breaking change'

搭配使用： git · github

Review a PR with one-line actionable comments

👤 Reviewers (and reviewees who dislike AI walls of text) ⏱ ~15 min beginner

何时使用： You're doing a quick pass and want pointed nits, not lectures.

步骤

Run caveman-review

/caveman-review — go through the diff. One line per comment.✓ 已复制

→ Inline comments read like 'rename x → userId for consistency with api/users.ts'
Escalate when needed

On the auth file specifically, switch off caveman for a full-length security review.✓ 已复制

→ Long-form only where the stakes justify it

结果： Faster review cycles; reviewees don't dismiss comments as noise.

注意事项

One-liners miss nuance on architectural changes — Architectural changes aren't Caveman's job — use default mode for those

搭配使用： github

Shrink CLAUDE.md and memory notes by 40–50% without losing intent

👤 Anyone whose CLAUDE.md grew past 5k tokens ⏱ ~10 min intermediate

何时使用： Your project memory is eating context every session and you know it could be tighter.

步骤

Compress in place

/caveman-compress CLAUDE.md — keep rules and facts, cut the prose.✓ 已复制

→ File shrinks ~46%; no rule deleted
Audit the diff

Show the diff. Any rule that changed meaning?✓ 已复制

→ Per-change verdict; rollbacks if intent drifted
Commit

/caveman-commit — single-line commit for the compression✓ 已复制

→ 'chore: compress CLAUDE.md (-46%)'

结果： Same rules, half the tokens.

注意事项

Compression drops a subtle caveat — Always diff-review after compressing rule files; intent loss is the main risk

搭配使用： filesystem

组合

与其他 MCP 搭配，撬动十倍杠杆

caveman-skill + git

Terse commit workflow

Stage the change, then /caveman-commit, then git push.✓ 已复制

caveman-skill + github

Caveman PR reviews at scale

For the 5 PRs in my review queue, /caveman-review each; post only actionable comments.✓ 已复制

caveman-skill + claude-mem-skill

Shrink memory transcripts without losing decisions

/caveman-compress the claude-mem notes for this project; flag anything where meaning shifted.✓ 已复制

工具

此 MCP 暴露的能力

工具	输入参数	何时调用	成本
/caveman	mode: Lite\|Full\|Ultra\|文言文	Toggle mode for the current task	free
/caveman-commit	staged diff (implicit)	At commit time; preserves staging	small model call
/caveman-review	PR diff	Quick review pass	small model call per file
/caveman-compress	file path	Shrink memory / rules files; diff-review before saving	small model call

成本与限制

运行它的成本

API 配额: None
每次调用 Token 数: By design — negative; saves tokens
费用: Free (MIT)
提示: Use Ultra only on genuinely mechanical output (commits, tags); leave design discussions in default mode

安全

权限、密钥、影响范围

凭据存储： None

数据出站： None — pure prompt shaping; no telemetry

Ultra mode can drop disclaimers and safety caveats. Don't use Ultra for legal, medical, or security advice output.

故障排查

常见错误与修复

Output still verbose after enabling Caveman

Most clients run Caveman per-turn; put /caveman Full at the top of each session or add it to CLAUDE.md

验证： First reply should feel distinctly terse

Caveman-commit returns multi-paragraph body

Usually triggers when the diff is genuinely large or breaks API. For true one-liner, add '—force-oneline'.

验证： Re-run with --force-oneline

Classical Chinese mode outputs garbled

Rare; usually a font / terminal issue, not the skill. Pipe to a file and open in an editor that supports CJK.

替代方案

Caveman 对比其他方案

替代方案	何时用它替代	权衡
System prompt with 'be terse'	You want it without a plugin	Inconsistent; Caveman's intensity levels + benchmarks give measurable results
Custom slash commands	You only need one of the sub-behaviors (e.g. terse commits)	Reinventing the wheel
