[Scenario 4: Developer Productivity with Claude] You are building developer productivity tooling on the Claude Agent SDK: helping engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate, and automate repetitive tasks — using the built-in tools (Read, Write, Edit, Bash, Grep, Glob) plus MCP servers. You are writing AgentDefinition configurations for the productivity system's subagents. Which TWO statements about subagents are accurate? (Select TWO.)

• A.Subagents automatically inherit the parent agent's full conversation history
• B.Each subagent's AgentDefinition carries its own description, system prompt, and tool restrictions for its role
• C.Subagents can be spawned without the Task tool if the prompt describes them clearly
• D.Subagents do not share memory between invocations — whatever context a subagent needs must be provided explicitly in its prompt
• E.Subagent tool restrictions are advisory and not enforced at runtime Scenario 5: Claude Code for Continuous Integration You are integrating Claude Code into a CI/CD pipeline for automated code review, test generation, and pull-request feedback — designing prompts that produce actionable findings while minimizing false positives.

Show answer & explanations

Correct answer: B, D

A: and C invert the isolation and spawning models — context never flows automatically, and Task is the spawning mechanism

B: Two load-bearing facts: subagents are configured individually (description, system prompt, tool restrictions), and they are isolated — no inherited history, no memory across invocations, so context passing is always explicit.

C: This option does not best satisfy the scenario requirements.

D: Two load-bearing facts: subagents are configured individually (description, system prompt, tool restrictions), and they are isolated — no inherited history, no memory across invocations, so context passing is always explicit.

E: is false — tool restrictions are configuration, not suggestion
