Sub-agent
Timeline (last 90 days)
Claude Code's sub-agents work in independent contexts and, upon completion, return only a summary of results to the main agent, achieving context isolation.
Polling sub-Agent records from line 1 requires pulling 68,844 tokens each time, whereas reading only the last 15 lines requires just 240 tokens, a difference of 62.6 times.
In most early Agent frameworks, sub-Agents share the same runtime, credentials, and environment variables as the parent Agent, with privilege inheritance being implicit and unrestricted.
The privilege attenuation model requires that a sub-Agent's permissions be a subset of the parent's permissions and must be explicitly granted rather than inherited by default.
