Sub-agent Governance

Use this file only in stages 3.2 and 3.3.

Phase Boundary

• Sub-agents are forbidden in stages 1, 2, 3.1, and 4.

Mandatory Parallelism Assessment

On entry to 3.2 or 3.3, assess whether:

• there are two or more independently acceptable Task IDs
• write sets can be split cleanly
• implementation, tests, review, or verification can run in parallel
• there is non-critical validation work that can proceed independently

If host policy permits delegation, user authorization exists when required, and any of those conditions are true, the main agent must create sub-agents unless a concrete write-set or coupling conflict makes delegation unsafe.

If sub-agents are not used, state why, such as:

• write-set conflict
• unsafe coupling
• insufficient context separation
• host policy or user-authorization limits

Hard Preconditions

Do not delegate unless all of these are true:

• the active plan.md or todo.md is confirmed
• the delegated task has a clear Task ID
• the task has a bounded write set
• the context package is complete
• host platform policy allows delegation
• user authorization exists when the host requires it

Non-delegable Responsibilities

The main agent must retain responsibility for:

• worktree creation
• plan.md or todo.md generation and confirmation
• requirements and architecture decisions
• file ownership definition
• conflict handling
• code integration
• final acceptance
• external status reporting

Inheritance Rule

• Sub-agents must inherit the main agent's model and reasoning configuration.
• Do not manually downgrade or override them unless the host platform requires an exact inherited value.

Required Context Package

Every delegated task must include:

• 阶段：3.2 or 3.3
• Workflow 目标
• 当前仓库
• 当前分支
• Base 分支
• Worktree 绝对路径
• 必须遵守的计划文档绝对路径
• 对应 Task ID / 标题
• 任务目标
• 验收条件
• 测试点
• 回滚点
• 允许修改的文件 / 目录
• 禁止修改的文件 / 目录
• 相关需求 / 架构摘要
• 关键代码 / 文档引用

Dispatch Rules

Tell each sub-agent:

• only complete the assigned Task ID
• obey the specified plan file
• stay inside the write set
• do not add plan-external changes
• do not revert user or other agent changes
• report changed files, test results, risks, and completion status

Required Sub-agent Output

Every delegated result must include:

• changed files
• key design points
• test and validation results
• risks and rollback notes
• whether the assigned Task ID is fully satisfied

Audit Rules

• The main agent remains responsible for integration and final acceptance.
• Review every sub-agent result before marking the task done.
• Record the delegation path in the final change archive.
