* feat: s01-s14 docs quality overhaul — tool pipeline, single-agent, knowledge & resilience Rewrite code.py and README (zh/en/ja) for s01-s14, each chapter building incrementally on the previous. Key fixes across chapters: - s01-s04: agent loop, tool dispatch, permission pipeline, hooks - s05-s08: todo write, subagent, skill loading, context compact - s09-s11: memory system, system prompt assembly, error recovery - s12-s14: task graph, background tasks, cron scheduler All chapters CC source-verified. Code inherits fixes forward (PROMPT_SECTIONS, json.dumps cache, real-state context, can_start dep protection, etc.). * feat: s15-s19 docs quality overhaul — multi-agent platform: teams, protocols, autonomy, worktree, MCP tools Rewrite code.py and README (zh/en/ja) for s15-s19, the multi-agent platform chapters. Each chapter inherits all previous fixes and adds one mechanism: - s15: agent teams (TeamCreate, teammate threads, shared task list) - s16: team protocols (plan approval, shutdown handshake, consume_inbox) - s17: autonomous agents (idle polling, auto-claim, consume_lead_inbox) - s18: worktree isolation (git worktree, bind_task, cwd switching, safety) - s19: MCP tools (MCPClient, normalize_mcp_name, assemble_tool_pool, no cache) All appendix source code references verified against CC source. Config priority corrected: claude.ai < plugin < user < project < local. * fix: 5 regressions across s05-s19 — glob safety, todo validation, memory extraction, protocol types, dep crash - s05-s09: glob results now filter with is_relative_to(WORKDIR) (inherited from s02) - s06-s08: todo_write validates content/status required fields (inherited from s05) - s09: extract_memories uses pre-compression snapshot instead of compacted messages - s16: submit_plan docstring clarifies protocol-only (not code-level gate) - s17-s19: match_response restores type mismatch validation (from s16) - s17-s19: claim_task deps list handles missing dep files without crashing * fix: s12 Todo V2 logic reversal, s14/s15 cron range validation, s18/s19 worktree name validation - s12 README (zh/en/ja): fix Todo V2 direction — interactive defaults to Task, non-interactive/SDK defaults to TodoWrite. Fix env var name to CLAUDE_CODE_ENABLE_TASKS (not TODO_V2). - s14/s15: add _validate_cron_field with per-field range checks (minute 0-59, hour 0-23, dom 1-31, month 1-12, dow 0-6), step > 0, range lo <= hi. Replace old try/except validation that only caught exceptions. - s18/s19: add validate_worktree_name() to remove_worktree and keep_worktree, not just create_worktree. * fix: align s16-s19 teaching tool consistency * fix pr265 chapter diagrams * Add comprehensive s20 harness chapter * Fix chapter smoke test regressions * Clarify README tutorial track transition --------- Co-authored-by: Haoran <bill-billion@outlook.com>

# s03: TodoWrite (待办写入)
|
|
|
|
`s01 > s02 > [ s03 ] s04 > s05 > s06 | s07 > s08 > s09 > s10 > s11 > s12`
|
|
|
|
> *"没有计划的 agent 走哪算哪"* -- 先列步骤再动手, 完成率翻倍。
|
|

|
|
> **Harness 层**: 规划 -- 让模型不偏航, 但不替它画航线。

## 问题
|
|
|
|
多步任务中, 模型会丢失进度 -- 重复做过的事、跳步、跑偏。对话越长越严重: 工具结果不断填满上下文, 系统提示的影响力逐渐被稀释。一个 10 步重构可能做完 1-3 步就开始即兴发挥, 因为 4-10 步已经被挤出注意力了。
|
|
|
|
## 解决方案
|
|
|
|
```
|
|
+--------+ +-------+ +---------+
|
|
| User | ---> | LLM | ---> | Tools |
|
|
| prompt | | | | + todo |
|
|
+--------+ +---+---+ +----+----+
|
|
^ |
|
|
| tool_result |
|
|
+----------------+
|
|
|
|
|
+-----------+-----------+
|
|
| TodoManager state |
|
|
| [ ] task A |
|
|
| [>] task B <- doing |
|
|
| [x] task C |
|
|
+----------- ------------+
|
|
|
|
|
if rounds_since_todo >= 3:
|
|
inject <reminder> into tool_result
|
|
```
|
|
|
|
## 工作原理
|
|
|
|
1. TodoManager 存储带状态的项目。同一时间只允许一个 `in_progress`。
|
|
|
|
```python
|
|
class TodoManager:
|
|
def update(self, items: list) -> str:
|
|
validated, in_progress_count = [], 0
|
|
for item in items:
|
|
status = item.get("status", "pending")
|
|
if status == "in_progress":
|
|
in_progress_count += 1
|
|
validated.append({"id": item["id"], "text": item["text"],
|
|
"status": status})
|
|
if in_progress_count > 1:
|
|
raise ValueError("Only one task can be in_progress")
|
|
self.items = validated
|
|
return self.render()
|
|
```
|
|
|
|
2. `todo` 工具和其他工具一样加入 dispatch map。
|
|
|
|
```python
|
|
TOOL_HANDLERS = {
|
|
# ...base tools...
|
|
"todo": lambda **kw: TODO.update(kw["items"]),
|
|
}
|
|
```
|
|
|
|
3. nag reminder: 模型连续 3 轮以上不调用 `todo` 时注入提醒。
|
|
|
|
```python
|
|
if rounds_since_todo >= 3 and messages:
|
|
last = messages[-1]
|
|
if last["role"] == "user" and isinstance(last.get("content"), list):
|
|
last["content"].insert(0, {
|
|
"type": "text",
|
|
"text": "<reminder>Update your todos.</reminder>",
|
|
})
|
|
```
|
|
|
|
"同时只能有一个 in_progress" 强制顺序聚焦。nag reminder 制造问责压力 -- 你不更新计划, 系统就追着你问。
|
|
|
|
## 相对 s02 的变更
|
|
|
|
| 组件 | 之前 (s02) | 之后 (s03) |
|
|
|----------------|------------------|--------------------------------|
|
|
| Tools | 4 | 5 (+todo) |
|
|
| 规划 | 无 | 带状态的 TodoManager |
|
|
| Nag 注入 | 无 | 3 轮后注入 `<reminder>` |
|
|
| Agent loop | 简单分发 | + rounds_since_todo 计数器 |
|
|
|
|
## 试一试
|
|
|
|
```sh
|
|
cd learn-claude-code
|
|
python agents/s03_todo_write.py
|
|
```
|
|
|
|
试试这些 prompt (英文 prompt 对 LLM 效果更好, 也可以用中文):
|
|
|
|
1. `Refactor the file hello.py: add type hints, docstrings, and a main guard`
|
|
2. `Create a Python package with __init__.py, utils.py, and tests/test_utils.py`
|
|
3. `Review all Python files and fix any style issues`
