Summary

BrightVision and other headless callers use Coder.create(..., args=SimpleNamespace(...)) via bright_vision_core.headless_args.default_headless_args(), which did not always define every flag the interactive CLI sets.

AgentCoder.initialize_mcp_tools() accessed self.args.verbose unconditionally, which raised:

AttributeError: 'types.SimpleNamespace' object has no attribute 'verbose'

when users ran /agent through the Vision HTTP API.

This change uses getattr(self.args, "verbose", False) (and treats missing args as false), matching the pattern already used in cecli/commands/run.py.

Not in scope

• Session encryption (feat(sessions): optional AES-256-GCM encryption for saved sessions #533)
• /add attachment staging paths (fix/add-attachment-staging-paths)

Test plan

• python -m pytest tests/core/test_headless_agent.py -q (BrightVision, with source activate.sh)
• E2E_LLM=1 python -m pytest tests/core/test_agent_llm.py -q (optional, needs Ollama)
• BrightVision: yarn tauri dev → Terminal Start → chat /agent short prompt → no verbose error in chat/terminal
