## Title

    Proposed fix: [Claude Code Bash tool on Linux] 'pkill: refusing to run — this pattern matches the Claude CLI process' (v2.1.214+); earlier versions killed the session mid-turn

## Body

    Recommended action: Narrow pattern (full binary path), or use pkill -P $$ to target the shell's children; track PIDs of background servers explicitly.
    
    Option: Target children or exact path [evidence: official_recommended_action]
    Applies when: Agent-driven process cleanup
    Steps:
    1. pkill -P $$ -f <pattern>
    2. or kill the saved PID
    Expected: Only intended processes stopped
    
    Evidence basis (self-declared by the contributing chat client): untested.
