~/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
    }
  }
}

開啟 Claude Desktop → Settings → Developer → Edit Config。儲存後重啟應用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "caveman-skill": {
      "command": "claude",
      "args": [

        "add",
        "JuliusBrussee/caveman"
      ],
      "_inferred": false
    }
  }
}

Cursor 使用與 Claude Desktop 相同的 mcpServers 格式。專案級設定優先於全域。

VS Code → Cline → MCP Servers → Edit

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

點擊 Cline 側欄中的 MCP Servers 圖示，然後選 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

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

格式與 Claude Desktop 相同。重啟 Windsurf 生效。

~/.continue/config.json

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

Continue 使用伺服器物件陣列，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 儲存後熱重載。

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

一行命令搞定。用 claude mcp list 驗證，claude mcp remove 移除。

使用場景

實戰用法： Caveman

Get crisp one-line commit messages for every patch

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

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

前置條件

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

步驟

Commit with caveman-commit

/caveman-commit — write a commit message for the staged changes.✓ 已複製

→ 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.✓ 已複製

→ git log shows 4 short commits

結果： Readable git log; bisect-friendly commits.

注意事項

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

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

步驟

Run caveman-review

/caveman-review — go through the diff. One line per comment.✓ 已複製

→ 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.✓ 已複製

→ Long-form only where the stakes justify it

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

注意事項

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

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

步驟

Compress in place

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

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

Show the diff. Any rule that changed meaning?✓ 已複製

→ Per-change verdict; rollbacks if intent drifted
Commit

/caveman-commit — single-line commit for the compression✓ 已複製

→ 'chore: compress CLAUDE.md (-46%)'

結果： Same rules, half the tokens.

注意事項

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

搭配使用： filesystem

組合

與其他 MCP 搭配，撬動十倍槓桿

caveman-skill + git

Terse commit workflow

Stage the change, then /caveman-commit, then git push.✓ 已複製

caveman-skill + github

Caveman PR reviews at scale

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

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.✓ 已複製

工具

此 MCP 暴露的能力

工具	輸入參數	何時呼叫	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

成本與限制

運行它的成本

API 配額: None
每次呼叫 Token 數: By design — negative; saves tokens
費用: Free (MIT)
提示: Use Ultra only on genuinely mechanical output (commits, tags); leave design discussions in default mode

安全

權限、密鑰、影響範圍

憑證儲存： None

資料出站： 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

常見錯誤與修復

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

驗證： 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'.

驗證： 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 對比其他方案

替代方案	何時用它替代	權衡
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
