large-task-orchestrator

large-task-orchestrator is a skill for Claude Code, Codex from hxy91819/mason-skills. It costs 27 tokens per session (2,378 once invoked), scanned A, original, MIT.

An orchestration workflow for carrying out an existing large-project plan through separate worker and validator agents. The orchestrator tracks dependencies, dispatches stories, gathers handoffs, and integrates results.

In plain words
What is it for?
Use it to run planned engineering stories, send each story to a dedicated worker, have another agent validate it, and manage fixes, integration, and user decisions.
Why use it?
It keeps implementation and validation responsibilities separate and prevents one work session from mixing unrelated stories. Progress remains tied to the plan and its evidence.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

large-task-orchestrator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/large_task_driver.py, scripts/large_task_report.py, tests/test_large_task_driver.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

大型任务 driver

这是流程类 Skill,仅在用户显式调用 $large-task-orchestrator 时运行。它只接管已经通过 large-task-planning v2 校验的计划:脚本是控制面,Worker、Validator 和异常时的 Judge 都是经 bb-dispatch 创建的短生命周期 BB 线程。

开始前阅读相邻的 large-task-planning 计划格式、bb-model-routing联合设计。计划 JSON 与 Git 是权威状态;每个 (仓库, 计划).local/large-task-orchestrator/<topic-slug>/ 保存可回看的运行事实。

生命周期用法

  1. 先确定用户指定的计划;未指定时只能使用当前仓库唯一的计划。阅读仓库规则、SPEC.mdSTATUS.md,检查 分支、git status --shortgit worktree list,保留并发改动。然后只对这个 (仓库, 计划) 查询状态:
python3 <orchestrator-skill>/scripts/large_task_driver.py status \
  --plan <topic>/agent/plan.json --stories-dir <topic>/agent/stories
  1. status 显示 driver 仍在运行,把 completed/total、每张 in-progress Story 的阶段、线程 ID 和难度翻译给 用户;不要自己运行主循环,也不要读线程全文。若 last_stop 非空或有 blocked Story,说明事实,并只向用户索取 继续所需的最小决定。需要停止时使用 stop [--wait];它只在当前 run_once 结束后退出,不会中断 BB 线程。

  2. 若没有运行中的 driver,用 start 启动指定计划。start 自己会先执行计划校验和 bb-dispatch --dry-run, 然后在新 session 中派生后台 run;本轮到此结束,向用户报告 pid、日志路径和后续状态命令。不要在本轮改用 前台 run 等待结果。

python3 <orchestrator-skill>/scripts/large_task_driver.py start \
  --plan <topic>/agent/plan.json \
  --stories-dir <topic>/agent/stories \
  --repository <repo-root> \
  --environment <bb-environment-id>

同一计划已有存活 pid 时 start 以退出码 4 拒绝重复启动;陈旧 pid 自动覆盖。不同仓库或同一仓库不同计划使用 独立的状态目录与锁,可以同时运行。计划中的 owner 保留 Worker 线程 ID;遗失计划本地状态时,driver 会从计划 和 BB 线程恢复。仅在排障或定时任务需要前台单次推进时才用 runstart --foreground--once

正常循环与异常

正常路径由 driver 选择 ready frontier、领取 Story、派 Worker、核对 Git 改动事实,再派 Validator 判断 Acceptance、Story 边界和 Worker 路径归属;通过后更新 Handoff、刷新投影并只 checkpoint Validator 确认归属的 Worker 路径。

发生 Worker blocked/failed、线程 error、待处理 interaction、空改动、报告无法解析或 Validator 多轮失败时,driver 才派 complex Judge。Judge 只能选择 retryescalatepatchblockreplanstopblock 后继续其他 ready Story;replan 后重新校验计划;stop 或没有 ready Story 时退出并把最小原因写到 stderr。

不要手动篡改 driver 状态文件、Story 的 owner 或 Handoff 来跳过这些状态转换。要处理停下原因,先读 driver status --json、计划状态和该计划的 jsonl;只有在既定 Goal 和授权内作出必要处理后,才在下一次本 Skill 调用时 按上述流程重新 start。需要凭据、权限、外部/破坏性动作、显著成本或稳定边界变更时才请用户决定。

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
