功能描述

Fork子Agent模式 — 子Agent继承父上下文。当需要子Agent了解父会话的关键上下文时自动激活。

使用说明 (SKILL.md)

Fork Mode — 子Agent上下文继承

参考 Claude Code 的 forkSubagent.ts 和 runForkedAgent()。

问题

sessions_spawn 创建的子Agent是全新会话，没有父会话的上下文。这导致子Agent缺少关键信息。

解决方案

在spawn子Agent时，手动注入父上下文。

Fork 模板

Step 1: 收集父上下文

需要注入的上下文：
1. 当前任务的目标和约束
2. 相关文件路径和关键代码片段
3. 已做出的决策和原因
4. 用户偏好（从MEMORY.md提取）
5. 项目结构概要

Step 2: 构建Fork Prompt

你是一个子Agent，从父会话 fork 出来。以下是你的继承上下文：

## 父会话上下文
{从Step 1收集的信息}

## 你的任务
{具体任务描述}

## 约束
- 工具白名单：{从Agent定义读取}
- 不要修改父会话的文件（除非明确要求）
- 完成后返回：{期望的输出格式}

Step 3: Spawn

sessions_spawn:
  runtime: "subagent"
  mode: "run"
  task: "{Fork Prompt}"
  streamTo: "parent"

上下文大小控制

上下文类型	最大长度	截断策略
任务目标	500字	保留核心需求
文件路径	10个文件	保留最相关的
代码片段	2000字	保留签名+关键逻辑
决策记录	5条	保留最新的
用户偏好	3条	保留最相关的

缓存共享（模拟Claude Code的CacheSafeParams）

OpenClaw没有prompt cache共享机制，但可以通过以下方式减少重复：

子Agent使用相同模型（model: zai/glm-5.1）
system prompt结构一致
避免在task中重复注入完整的SKILL.md内容

适用场景

场景	Fork模式	普通spawn
需要了解项目背景	✅	❌
需要知道已做决策	✅	❌
纯机械任务（格式化、搜索）	❌	✅
需要用户偏好	✅	❌
独立的新项目	❌	✅

安全使用建议

This skill appears internally consistent, but it explicitly recommends copying parent-session context (including MEMORY.md entries, code snippets, file paths, and decision history) into spawned subagents. Before installing or using it: 1) Review what your agent stores in MEMORY.md and other session memories — remove or redact secrets (API keys, passwords, PII) that should not be shared with child agents. 2) Ensure the agent's tool whitelist and permissions are correctly configured so forked subagents cannot access additional tools or external endpoints. 3) Limit which files and how much code are injected (follow the documented truncation rules). 4) Test in a safe environment with non-sensitive data to verify behavior. If you need stricter controls (e.g., preventing any memory sharing), do not enable this skill or modify the fork template to sanitize or omit sensitive fields.

功能分析

Type: OpenClaw Skill Name: lobster-fork-mode Version: 1.0.0 The 'lobster-fork-mode' skill is a utility designed to improve sub-agent performance by providing a template for context inheritance. It outlines a process for gathering session data (goals, code snippets, and user preferences) and passing it to child agents via the 'sessions_spawn' tool. The logic is entirely focused on internal agent coordination and lacks any indicators of data exfiltration, malicious execution, or unauthorized access.

能力评估

✓ Purpose & Capability

The skill's metadata declares sessions_spawn, read, and memory_search capabilities which are precisely what a 'forked subagent inheriting parent context' feature needs. No unrelated binaries, env vars, or config paths are requested.

ℹ Instruction Scope

SKILL.md explicitly instructs collecting parent task goals, file paths, code snippets, decision history, and user preferences (from MEMORY.md) and injecting them into the child agent. That is coherent with the purpose but means the subagent will receive potentially sensitive context; the instructions themselves do not attempt to access anything beyond the declared capabilities.

✓ Install Mechanism

Instruction-only skill with no install spec and no code files — minimal attack surface from installation.

✓ Credentials

No environment variables, credentials, or external config are requested. The declared read and memory_search capabilities justify the data the skill asks to access.

✓ Persistence & Privilege

always is false and the skill is user-invocable and allowed to be invoked autonomously (platform default). The skill does not request permanent system presence or modify other skills' configs.
