Covers C/C++, Rust, Solidity, Python, Go, TypeScript
Defensive-only: audit/review flows, not offensive tooling
Modular — pull individual skills without adopting the whole bundle

選擇你的客戶端

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

{
  "mcpServers": {
    "trailofbits-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/trailofbits/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "trailofbits-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/trailofbits/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

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": {
    "trailofbits-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/trailofbits/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "trailofbits-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/trailofbits/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

格式與 Claude Desktop 相同。重啟 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "trailofbits-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/trailofbits/skills",
        "~/.claude/skills/skills"
      ]
    }
  ]
}

Continue 使用伺服器物件陣列，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "trailofbits-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/trailofbits/skills",
          "~/.claude/skills/skills"
        ]
      }
    }
  }
}

加入 context_servers。Zed 儲存後熱重載。

claude mcp add trailofbits-skill -- git clone https://github.com/trailofbits/skills ~/.claude/skills/skills

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： Trail of Bits Skills

Add a security-review pass to every PR

👤 Teams without a dedicated security engineer ⏱ ~30 min intermediate

何時使用： Your PRs currently go straight from code-review to merge — no security eyes.

前置條件

Skills installed — git clone https://github.com/trailofbits/skills ~/.claude/skills/trailofbits

步驟

Scope the diff

Use trailofbits/pr-review skill on the current PR. List files the skill thinks are security-relevant with reasons.✓ 已複製

→ Concrete file-by-file relevance reasons
Deep review

For each flagged file, run the appropriate domain skill (crypto, input-validation, auth). Report findings with severity.✓ 已複製

→ Severity-ranked list with code refs
Summary for reviewer

Write a 5-bullet PR comment summarizing the findings, non-scary but precise.✓ 已複製

→ Reviewer-friendly summary with exact line citations

結果： A security review comment on every PR that catches real issues without drowning you in false positives.

注意事項

Skill flags style issues as security — Calibrate by prompting: "focus on exploitable issues only"

搭配使用： github · filesystem

Audit cryptographic code paths in a service

👤 Devs maintaining auth/encryption code ⏱ ~90 min advanced

何時使用： You have a JWT/HMAC/encryption layer and want someone smart to double-check.

步驟

Find crypto

Use trailofbits/crypto-review. Scan /src for files that touch crypto APIs. Report them.✓ 已複製

→ Crypto call-site inventory
Audit each

For each site: what algorithm? Key management? Nonce reuse risk? IV handling? Cite source.✓ 已複製

→ Per-site audit with code refs
Remediation plan

For any medium+ finding, draft a remediation — concrete code change, not "consider using ...".✓ 已複製

→ Applicable diffs, not vague advice

結果： A crypto audit report with concrete fixes, from a baseline of common mistakes ToB has seen in real engagements.

注意事項

Not a substitute for a real audit — Use for self-review; hire professionals before launch of high-value surfaces

搭配使用： github

組合

與其他 MCP 搭配，撬動十倍槓桿

trailofbits-skill + github

Post findings as a PR review comment

Post the review as a PR comment — severities as labels.✓ 已複製

trailofbits-skill + filesystem

Scan the whole repo offline

Run the full security sweep across /src and write report to /audit/report.md.✓ 已複製

工具

此 MCP 暴露的能力

工具	輸入參數	何時呼叫
scope_review	diff\|path	Before deep dive
crypto_review	path	Crypto code specifically
input_validation_review	path	API/boundary code
iac_review	path	Terraform / CloudFormation / K8s manifests

成本與限制

運行它的成本

API 配額: N/A
每次呼叫 Token 數: Review is reading-heavy; budget proportional to diff size
費用: Free (CC-BY-SA)
提示: Scope first — don't run deep skills on irrelevant files

安全

權限、密鑰、影響範圍

最小權限： filesystem-read

憑證儲存： None

資料出站： None from skill; reviewed code is in your LLM context

切勿授予： write access unless auto-remediating

Not a replacement for a formal security audit — use it to catch the obvious before paying for experts

故障排查

常見錯誤與修復

Skill flags safe code as vulnerable

Ask for rationale; if weak, dismiss with reason. Calibration improves over sessions.

Misses obvious bugs

The skill codifies Trail of Bits' patterns — if your stack is unusual (e.g. niche Rust crate), it may miss. Add custom patterns.

Outputs too long to review

Constrain: "top 5 highest-severity findings only"

替代方案

Trail of Bits Skills 對比其他方案

替代方案	何時用它替代	權衡
Semgrep rules	You want static analysis in CI, not interactive review	Narrower pattern set; no LLM reasoning
CodeQL	You want deep dataflow analysis	Much more setup; not a skill
