What problem does it solve? Answering "what does the crew already know about X" normally requires manually reading every persona's memory file and every pending inbox handoff. Echo replaces that with one parallel sweep that searches all memory files at once and returns a unified, deduplicated answer. ## Core Features & Use Cases - Parallel memory search: Spawns blind subagents, each searching a slice of memory/agents/*.md and memory/inbox/*.md files, then unions and deduplicates the results. - Scoped queries: Search full memory, agents only, inboxes only, or specific personas depending on whether you want settled knowledge or pending handoffs. - Ranked, honest reporting: Matches are ranked by relevance with full coverage reporting, including which files had zero hits and what was not found. - Use Case: Before starting a new task, ask "what did we decide about the caching strategy?" and get every relevant memory entry across all personas in one read-only pass. ## Quick Start Ask the assistant to run an echo search across crew memory for what the team already knows about a specific topic.
