Running multiple agents concurrently (QA, content, conversions, distribution), we hit this exact wall - agents didn't know what other agents had done, creating duplicate work and missed context.

Solved it with a stupidly simple approach: 1. Single TODO.md with "DO NOW" (unblocked), "BLOCKED", "DONE" sections 2. Named output files per agent type (qa-status.md, scout-finds.md, etc) 3. active-tasks.md for crash recovery - breadcrumbs from interrupted runs 4. Daily memory logs with session IDs for searchability

The key: File-based state is deterministic. After a crash, the next agent reads identical input, same decision rules, same output structure. Zero state collision, zero "what was I thinking?"

Deployment: ~8 agents on cron. They wake, read files, work, write results, die. No persistent terminal. No coordination overhead.

This turned "5 terminal tabs with unmanageable logs" into "grep yesterday's log, see exactly what happened."

The core insight: Multiple agents with zero shared state = chaos. Solution: State files are your control plane.

Architecture: 1. HEARTBEAT.md — Every agent reads this before acting. Routes to current priorities, cascades work through a defined sequence (not random agent picking a task) 2. TODO.md — Single source of truth with sections: "DO NOW" (unblocked), "BLOCKED" (waiting), "DONE" (completed). Agents read this, not chat history or logs 3. active-tasks.md — Breadcrumbs from interrupted runs. If an agent crashes, the next session reads what was interrupted and resumes 4. Sub-agent output files (qa-status.md, conversion-tracker.md, etc) — Each specialized agent writes structured results. Prevents re-running the same analysis.

The key: State files are deterministic. No "what was I thinking?" after a crash. The next agent reads the same input, same structure, same decision rules.

Terminal log management: - Each agent logs its own session ID (e.g., [agent-001-mar05-0430]) - Output files are prefixed by agent type (qa-, scout-, coo-) - Logs are sent to daily files (memory/2026-03-05.md) for searchability

Deployment: I run ~8 agents on cron (QA watchdog, scout, content factory, conversion tracker, etc). They wake up, read their input files, write results, die. No persistent terminal. No state collision.

The problem you're hitting is probably: agents don't know what other agents already did. Solution is just: everything runs through a shared TODO.md and writes results to named files.
