Coding Agent Prompt Audit and Optimization

paste this into your coding agent and it audits your harness, finds everything being resent on every turn for nothing, and cuts it. it starts by instrumenting what isn't being logged, then renders your real requests and counts tokens section by section. you get a ranked list of what's worth removing, weighed against what each cut would cost you in quality. then it goes through the system prompt line by line. keep, rewrite, delete, or move. guardrails written for weaker models get deleted. commands get rewritten as plain descriptions. anything that changes per request moves out of the cached prefix.
