Subagent ignores explicit instruction to skip test execution

Summary

When a subagent is explicitly told in the prompt 'Do NOT run mvn test — run mvn compile only', it runs the full test suite anyway.

Environment

• Claude Code CLI: 2.1.160
• OS: Windows 11

Steps to reproduce

1. Dispatch a subagent with prompt containing: 'Do NOT run mvn test or mvn verify. Run mvn compile -q only.'
2. Observe: agent runs mvn verify (full test suite + Spring context boot)

Expected

Agent respects explicit tool-use constraints in the prompt.

Impact

Causes unnecessary 15-30 min delays per agent from cold Maven dependency downloads.
