Paperclip agent instructions are injected via adapter_config.instructionsFilePath.

Paperclip agent instructions are injected via adapter_config.instructionsFilePath. The path must be container-internal (/home/node/.claude/agent-instructions/.md), not host path. Host files at /root/.claude/agent-instructions/ are auto-mounted via the existing /root/.claude:/home/node/.claude:ro volume — no docker-compose change needed. The adapter reads the file, writes a combined version to skillsDir, then passes to claude CLI via —append-system-prompt-file.
