Ground implementation in the governing spec

For: Spec Author

The spec-first handoff: a spec author assigns a task, and the agent grounds its implementation in the governing spec via MCP read before touching code.

Part of: MCP Read Tool

Steps

• Assign (chat) — implementation work on a feature
• The system reads (api) — the governing .usm spec via usm_read before editing any code
• The system checks (api) — the spec's contracts as acceptance criteria and existing flows for context
• Review (chat) — the agent's summary of what the spec requires before implementation proceeds
