[synthesis] Claude Code-style long-running agent loses track of the task, drifts, or becomes undebuggable

Use a single-threaded master loop with a flat message history, explicit TODO-based planning, context compression at ~92% utilization, and limited sub-agent spawning with strict depth limits. Prioritize debuggability over multi-agent swarm elegance.

Journey Context:
The industry default is to add more agents when autonomy breaks. Anthropic's Claude Code architecture shows the opposite: a deliberately simple 'n0' master loop with one flat history, an 'h2A' steering queue for real-time course correction, and a 'wU2' compressor that summarizes at 92% context usage. This avoids the emergent behavior and context pollution that make multi-agent swarms hard to operate. Sub-agents \(I2A\) exist but are depth-limited to prevent explosion. The takeaway is that controllable autonomy at scale comes from disciplined tooling and memory hygiene, not from adding planner/critic/executor personas.
