Cheat sheet

Stack choice

From lesson 0016. Name the failure. Climb one rung. Measure before you keep it.

1. ContextWindow is the failure. Catalog, JIT, compact, notes.
2. LoopHeartbeat is the failure. Verify, stop, schedule.
3. GraphA path must always hold. Hybrid: holes for agents.

Not rungs

• Prompt / Guide = pack the call + AGENTS.md. Enough until the window or a path fails. Team floor.
• Harness wraps a one-call, a loop, or a graph. Harness card.
• Evals keep the climb. Evals card.
• Open research: do not graph. Graph card.

Anthropic: simplest first; add complexity when it demonstrably improves outcomes. Developer picks the rung; lead puts it in Guide / Guard / Job.
