* 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>

|

s14: Cron Scheduler — independent daemon thread + queue processor.
|
||||
|
||||
Run: python s14_cron_scheduler/code.py
|
||||
Need: pip install anthropic python-dotenv + .env with ANTHROPIC_API_KEY
|
||||
|
||||
Changes from s13:
|
||||
- CronJob dataclass (id, cron, prompt, recurring, durable)
|
||||
- cron_matches: 5-field cron expression matching with DOM/DOW OR semantics
|
||||
- schedule_job / cancel_job: register/remove cron jobs (with validation)
|
||||
- cron_scheduler_loop: independent daemon thread, polls every 1s
|
||||
- cron_queue: thread-safe queue, scheduler writes, queue processor delivers
|
||||
- queue_processor_loop: auto-runs agent_loop when cron_queue has work
|
||||
- Durable storage: .scheduled_tasks.json (survives restart)
|
||||
- 3 new tools: schedule_cron, list_crons, cancel_cron
|
||||
|
||||
Four layers:
|
||||
1. Scheduler: daemon thread checks time → fires matching jobs
|
||||
2. Queue: cron_queue decouples scheduler from agent loop
|
||||
3. Queue processor: wakes the agent when queued work exists and it is idle
|
||||
4. Consumer: agent_loop consumes queued jobs and injects them into messages
