Subagent Spawning With Context Isolation

Bash is all you need - A nano claude code–like 「agent harness」, built from 0 to 1

Unique: Implements context isolation as a first-class pattern by giving each subagent its own tool registry and knowledge base, rather than sharing the parent's full context. This makes permission boundaries explicit and teachable.

vs others: More explicit about isolation than frameworks like LangChain's SubTask agents, which often share parent context by default. This design forces developers to think about what each agent should know and can do.
