# Agent Base Image — multi-stage build
# =============================================================================
# Shared runtime for Claude Code agent containers: Python venv + Node.js +
# @anthropic-ai/claude-code CLI. Specialized images (agent-dev-be, agent-qa-fe,
# etc.) extend this one.

# servers fail to start and the agent falls back to raw HTTP, losing every
# guardrail and inline schema the MCP layer provides.

USER agent

# Workspaces are cloned by the orchestrator (running as root) into a shared
# volume, so inside the agent container they show up owned by a different
# uid. Git 2.35+ refuses to operate on such repos with "dubious ownership"
# until safe.directory is set. `*` trusts everything, which is fine inside
# a per-agent sandbox that only mounts its own workspace.
