Maps codebases of any size using parallel Sonnet subagents.
CRITICAL: Opus orchestrates, Sonnet reads. Never have Opus read codebase files directly. Always delegate file reading to Sonnet subagents - even for small codebases. Opus plans the work, spawns subagents, and synthesizes their reports.
使用并行的Sonnet子代理绘制任意规模的代码库。
重要提示:由Opus编排,Sonnet负责读取。 绝不要让Opus直接读取代码库文件。始终将文件读取任务委托给Sonnet子代理——即使是小型代码库也不例外。Opus负责规划工作、生成子代理,并综合它们的报告。
Quick Start
快速开始
- Run the scanner script to get file tree with token counts
- Analyze the scan output to plan subagent work assignments
- Spawn Sonnet subagents in parallel to read and analyze file groups
- Synthesize subagent reports into
docs/CODEBASE_MAP.md - Update with summary pointing to the map
CLAUDE.md
- 运行扫描脚本以获取包含令牌计数的文件树
- 分析扫描输出以规划子代理的工作分配
- 并行生成Sonnet子代理来读取和分析文件组
- 将子代理的报告整合到中
docs/CODEBASE_MAP.md - 更新文件,添加指向该地图的摘要

Workflow
工作流程
Step 1: Check for Existing Map
步骤1:检查现有地图
First, check if already exists:
docs/CODEBASE_MAP.mdIf it exists:
- Read the timestamp from the map's frontmatter
last_mapped - Check for changes since last map:
- Run if git available
git log --oneline --since="<last_mapped>" - If no git, run the scanner and compare file counts/paths
- Run
- If significant changes detected, proceed to update mode
- If no changes, inform user the map is current
If it does not exist: Proceed to full mapping.
首先,检查是否已存在:
docs/CODEBASE_MAP.md如果已存在:
- 从地图的前置元数据中读取时间戳
last_mapped - 检查自上次映射以来的更改:
- 如果有Git环境,运行
git log --oneline --since="<last_mapped>" - 如果没有Git,运行扫描脚本并比较文件计数/路径
- 如果有Git环境,运行
- 如果检测到重大更改,进入更新模式
- 如果没有更改,告知用户当前地图是最新的
如果不存在: 执行完整映射流程。
Step 2: Scan the Codebase
步骤2:扫描代码库
Run the scanner script to get an overview. Try these in order until one works:
bash
undefined运行扫描脚本以获取代码库概览。按以下顺序尝试,直到找到可行的方式:
bash
undefinedOption 1: UV (preferred - auto-installs tiktoken in isolated env)
选项1:UV(优先选择 - 在隔离环境中自动安装tiktoken)
uv run ${CLAUDE_PLUGIN_ROOT}/skills/cartographer/scripts/scan-codebase.py . --format json
uv run ${CLAUDE_PLUGIN_ROOT}/skills/cartographer/scripts/scan-codebase.py . --format json
Option 2: Direct execution (requires tiktoken installed)
选项2:直接执行(需要已安装tiktoken)
${CLAUDE_PLUGIN_ROOT}/skills/cartographer/scripts/scan-codebase.py . --format json
${CLAUDE_PLUGIN_ROOT}/skills/cartographer/scripts/scan-codebase.py . --format json
Option 3: Explicit python3
选项3:显式使用python3
python3 ${CLAUDE_PLUGIN_ROOT}/skills/cartographer/scripts/scan-codebase.py . --format json
**Note:** The script uses UV inline script dependencies. When run with `uv run`, tiktoken is automatically installed in an isolated environment - no global pip install needed.
If not using UV and tiktoken is missing:
```bash
pip install tiktokenpython3 ${CLAUDE_PLUGIN_ROOT}/skills/cartographer/scripts/scan-codebase.py . --format json
**注意:** 该脚本使用UV内联脚本依赖。使用`uv run`运行时,tiktoken会自动安装在隔离环境中——无需全局pip安装。
如果不使用UV且缺少tiktoken:
```bash
pip install tiktokenor
或
pip3 install tiktoken
The output provides:
- Complete file tree with token counts per file
- Total token budget needed
- Skipped files (binary, too large)pip3 install tiktoken
扫描输出包含:
- 包含每个文件令牌计数的完整文件树
- 所需的总令牌预算
- 已跳过的文件(二进制文件、过大文件)Step 3: Plan Subagent Assignments
步骤3:规划子代理分配
Analyze the scan output to divide work among subagents:
Token budget per subagent: ~150,000 tokens (safe margin under Sonnet's 200k context limit)
Grouping strategy:
- Group files by directory/module (keeps related code together)
- Balance token counts across groups
- Aim for more subagents with smaller chunks (150k max each)
For small codebases (<100k tokens): Still use a single Sonnet subagent. Opus orchestrates, Sonnet reads - never have Opus read the codebase directly.
Example assignment:
Subagent 1: src/api/, src/middleware/ (~120k tokens)
Subagent 2: src/components/, src/hooks/ (~140k tokens)
Subagent 3: src/lib/, src/utils/ (~100k tokens)
Subagent 4: tests/, docs/ (~80k tokens)分析扫描输出,将工作分配给各个子代理:
每个子代理的令牌预算: ~150,000令牌(在Sonnet的200k上下文限制内的安全余量)
分组策略:
- 按目录/模块分组文件(将相关代码放在一起)
- 在各组之间平衡令牌计数
- 尽量使用更多子代理处理较小的代码块(每个最多150k令牌)
对于小型代码库(<100k令牌): 仍使用单个Sonnet子代理。由Opus编排,Sonnet负责读取——绝不要让Opus直接读取代码库。
分配示例:
子代理1:src/api/, src/middleware/ (~120k令牌)
子代理2:src/components/, src/hooks/ (~140k令牌)
子代理3:src/lib/, src/utils/ (~100k令牌)
子代理4:tests/, docs/ (~80k令牌)Step 4: Spawn Sonnet Subagents in Parallel
步骤4:并行生成Sonnet子代理
Use the Task tool with and for each group.
subagent_type: "Explore"model: "sonnet"CRITICAL: Spawn all subagents in a SINGLE message with multiple Task tool calls.
Each subagent prompt should:
- List the specific files/directories to read
- Request analysis of:
- Purpose of each file/module
- Key exports and public APIs
- Dependencies (what it imports)
- Dependents (what imports it, if discoverable)
- Patterns and conventions used
- Gotchas or non-obvious behavior
- Request output as structured markdown
Example subagent prompt:
You are mapping part of a codebase. Read and analyze these files:
- src/api/routes.ts
- src/api/middleware/auth.ts
- src/api/middleware/rateLimit.ts
[... list all files in this group]
For each file, document:
1. **Purpose**: One-line description
2. **Exports**: Key functions, classes, types exported
3. **Imports**: Notable dependencies
4. **Patterns**: Design patterns or conventions used
5. **Gotchas**: Non-obvious behavior, edge cases, warnings
Also identify:
- How these files connect to each other
- Entry points and data flow
- Any configuration or environment dependencies
Return your analysis as markdown with clear headers per file/module.使用Task工具,为每个组设置和。
subagent_type: "Explore"model: "sonnet"重要提示:在单个消息中通过多个Task工具调用生成所有子代理。
每个子代理的提示应包含:
- 列出要读取的特定文件/目录
- 请求分析以下内容:
- 每个文件/模块的用途
- 关键导出和公共API
- 依赖项(它导入的内容)
- 依赖它的模块(如果可发现,哪些模块导入了它)
- 使用的模式和约定
- 需要注意的陷阱或非明显行为
- 请求以结构化markdown格式输出
子代理提示示例:
你正在映射代码库的一部分。请读取并分析以下文件:
- src/api/routes.ts
- src/api/middleware/auth.ts
- src/api/middleware/rateLimit.ts
[...列出该组中的所有文件]
请为每个文件记录:
1. **用途**:一行描述
2. **导出**:导出的关键函数、类、类型
3. **导入**:值得注意的依赖项
4. **模式**:使用的设计模式或约定
5. **陷阱**:非明显行为、边缘情况、警告
此外请识别:
- 这些文件之间的关联方式
- 入口点和数据流
- 任何配置或环境依赖项
请以markdown格式返回分析结果,每个文件/模块使用清晰的标题。Step 5: Synthesize Reports
步骤5:整合报告
Once all subagents complete, synthesize their outputs:
- Merge all subagent reports
- Deduplicate any overlapping analysis
- Identify cross-cutting concerns (shared patterns, common gotchas)
- Build the architecture diagram showing module relationships
- Extract key navigation paths for common tasks
所有子代理完成任务后,整合它们的输出:
- 合并所有子代理的报告
- 去重任何重叠的分析内容
- 识别跨模块关注点(共享模式、常见陷阱)
- 构建架构图,展示模块之间的关系
- 提取常见任务的关键导航路径
Step 6: Write CODEBASE_MAP.md
步骤6:编写CODEBASE_MAP.md
CRITICAL: Get the actual timestamp first! Before writing the map, fetch the current time:
bash
date -u +"%Y-%m-%dT%H:%M:%SZ"Use this exact output for both the frontmatter field and the header text. Never estimate or hardcode timestamps.
last_mappedCreate using this structure:
docs/CODEBASE_MAP.mdmarkdown
---
last_mapped: YYYY-MM-DDTHH:MM:SSZ
total_files: N
total_tokens: N
---重要提示:先获取实际时间戳! 在编写地图之前,获取当前时间:
bash
date -u +"%Y-%m-%dT%H:%M:%SZ"将此精确输出同时用于前置元数据的字段和标题文本。绝不要估算或硬编码时间戳。
last_mapped使用以下结构创建:
docs/CODEBASE_MAP.mdmarkdown
---
last_mapped: YYYY-MM-DDTHH:MM:SSZ
total_files: N
total_tokens: N

更新模式
When updating an existing map:
- Identify changed files from git or scanner diff
- Spawn subagents only for changed modules
- Merge new analysis with existing map
- Update timestamp (run
last_mappedto get actual time)date -u +"%Y-%m-%dT%H:%M:%SZ" - Preserve unchanged sections
更新现有地图时:
- 从Git或扫描器差异中识别已更改的文件
- 仅为已更改的模块生成子代理
- 将新的分析内容与现有地图合并
- 更新时间戳(运行
last_mapped获取实际时间)date -u +"%Y-%m-%dT%H:%M:%SZ" - 保留未更改的部分
Token Budget Reference
令牌预算参考
| Model | Context Window | Safe Budget per Subagent |
|---|---|---|
| Sonnet | 200,000 | 150,000 |
| Opus | 200,000 | 100,000 |
| Haiku | 200,000 | 100,000 |
Always use Sonnet subagents - best balance of capability and cost for file analysis.
| 模型 | 上下文窗口 | 每个子代理的安全预算 |
|---|---|---|
| Sonnet | 200,000 | 150,000 |
| Opus | 200,000 | 100,000 |
| Haiku | 200,000 | 100,000 |
始终使用Sonnet子代理——在文件分析方面,它在能力和成本之间达到了最佳平衡。
Troubleshooting
故障排除
Scanner fails with tiktoken error:
bash
pip install tiktoken扫描器因tiktoken错误失败:
bash
pip install tiktokenor
或
pip3 install tiktoken
pip3 install tiktoken
or with uv:
或使用uv:
uv pip install tiktoken
**Python not found:**
Try `python3`, `python`, or use `uv run` which handles Python automatically.
**Codebase too large even for subagents:**
- Increase number of subagents
- Focus on src/ directories, skip vendored code
- Use `--max-tokens` flag to skip huge files
**Git not available:**
- Fall back to file count/path comparison
- Store file list hash in map frontmatter for change detectionuv pip install tiktoken
**找不到Python:**
尝试`python3`、`python`,或使用`uv run`,它会自动处理Python环境。
**代码库太大,即使使用子代理也无法处理:**
- 增加子代理数量
- 重点处理src/目录,跳过第三方代码
- 使用`--max-tokens`标志跳过超大文件
**没有Git环境:**
- 退回到文件计数/路径比较
- 在地图前置元数据中存储文件列表哈希值以检测更改
