Spec-driven tools
MCP, built-in, and external tools share one model-visible contract instead of scattered ad-hoc prompts.
Orca MCP tools extend the local coding agent with external tool servers while preserving spec-driven tools, approval policies, sandbox behavior, and resumable transcripts.

Tool contract
MCP, built-in, and external tools share one model-visible contract instead of scattered ad-hoc prompts.
Tool capabilities determine whether calls run directly, ask for approval, or stay blocked by policy.
Tool requests, outputs, approvals, and failures stay in the local JSONL transcript for later review.
