Sequential Thinking MCP (--deepthink)

Structured step-by-step reasoning via mcp__sequential-thinking__sequentialthinking MCP tool.

CRITICAL: Two Distinct Modes

MoAI has TWO independent deep analysis modes. They are NOT the same thing:

Mode	Trigger	Mechanism	MCP Tool?	GLM Compatible?
`--deepthink`	Explicit `--deepthink` flag	Sequential Thinking MCP tool	YES — `mcp__sequential-thinking__sequentialthinking`	NO — generates server_tool_use content type
`ultrathink`	Keyword or auto-detection	Claude native extended reasoning (high effort)	NO — native to Claude	YES — no special content type

Rules:

--deepthink → ALWAYS invoke Sequential Thinking MCP. NEVER use for native reasoning.
ultrathink → ALWAYS use Claude's native extended reasoning. NEVER invoke Sequential Thinking MCP.
They can coexist: ultrathink --deepthink activates BOTH modes independently.
