Multi-Agent Council — Agent Team Coordination

Production-grade multi-agent coordination using real subagent spawning via Task(), deterministic CLI for all structural operations, and file-based handoffs between agents. Each agent runs in its own fresh 200k context. The orchestrator stays lean (~10-15% context usage).

Iron Law

Every council operation that touches file naming, numbering, state transitions,
or validation MUST go through the planning-tools CLI. Agents execute —
the CLI manages structure.

This is non-negotiable. LLMs cannot reliably handle sequential numbering, state machine transitions, or structural validation. The CLI does this deterministically. Agents focus on what LLMs are good at: reasoning, writing, and analysis.
