Why your AI agent needs Plan mode

AI coding assistants can do incredible things — write code, fix bugs, refactor entire projects. But giving an AI unrestricted access to your codebase can be risky. That is why we built Plan mode.

Plan mode is a read-only agent that can explore your codebase, analyze architecture, understand dependencies, and suggest changes — without ever modifying a single file.

Why use Plan mode?

Safe exploration: Navigate the codebase freely with zero risk of accidental modifications

Architecture analysis: Understand project structure, dependency graphs, and code patterns

Code review: Get detailed feedback and improvement suggestions without automated changes

Change planning: Have the AI plan a multi-step refactor before execution

Plan mode is available on all FBC Agent plans, including the free trial.
