RooCode 5-Mode Architecture
Overview (confidence: high)
RooCode implements the most sophisticated multi-file agent system in the corpus. It has five distinct modes — Code, Architect, Ask, Debug, and Custom — each with its own persona, tool access, workflow rules, and a handoff protocol between modes.
Five-Mode Architecture (confidence: high)
Each mode has specialized behavior:
- Architect: Formal and structured persona. Cannot modify files. Must produce specifications. Produces a spec that is handed off to Code mode.
- Code: Practical, implementation-focused persona. Can modify files. Implements from Architect specs. Must plan before implementing.
- Ask: Q&A-focused persona. Accesses search and documentation tools. No file modification capability.
- Debug: Diagnostic persona. Specialized tool access for debugging workflows.
- Custom: User-configurable mode for specialized tasks.
This multi-file-agent-architecture enables specialization without the bloat of monolithic prompts.
Handoff Protocol (confidence: high)
Modes pass work to each other through a structured handoff: Architect produces a specification, then Code implements it, then Debug can fix issues. This clean information flow between roles enables complex workflows impossible in monolithic prompts.
Additional Patterns (confidence: high)
- Plan-before-implement hard gate in Code mode
- Task state machine for todo tracking within each mode
- Public CoT display: All reasoning visible to user
- Skills directory gate: Checks available skills before task execution
Implications (confidence: high)
RooCode’s 5-mode architecture is the most sophisticated multi-file system in the corpus. The handoff protocol between modes enables complex workflows impossible in monolithic prompts. This pattern points toward the future of agent specialization.
