Short, repeatable routines for working with coding agents \u2014 each loop is a tight cycle with copy-paste prompts, a clear stop rule, and notes on what usually goes wrong. Written from lab practice: small batches, quoted evidence, no open-ended \u201ckeep going\u201d. Pick a loop, run it top to bottom, stop when the exit criteria say so.
No installs, no backend \u2014 just prompts you hand to the agent you already use, plus guardrails that keep each cycle honest.
Every loop follows the same contract: one prompt per turn, quoted evidence back, stop at the exit criteria. Open a loop, copy the first prompt box into your agent, paste the result where asked, and move to the next step only when the \u201cwhy\u201d line is satisfied. If a step fails twice, use the failure-mode guardrail instead of pushing through \u2014 that is what the guardrails are for.
