Cross-thread view of what the AI SDR intends to do: filter state eq proposed for everything waiting on approval, active for what is running, or conversation_sid for one thread's plan history; page_size 0 returns counts alone. A skipped or failed step says why in its cause; a pending step whose message cannot leave yet says what it waits for. One lead is better read on its thread (get_conversation carries the active plan); why a plan looks the way it does is a run fact: search_agent_runs.

Contract:

• MCP tool search_agent_plans, registry package mcp.unibox/agent_plans, mount unibox.agent.
• Operation search, response envelope search.
• Flags: read only.
