A practical guide for operators who want to funnel coding agent review steps — PR analysis, lint checks, test failure explanations — through CometAPI endpoints without losing conversation context or accumulating stale endpoint references.
Coding agents read instruction files — AGENTS.md, CLAUDE.md, .github/copilot-instructions.md, and memory files — to understand what tools, workflows, and conventions are available. When those files drift from the actual runtime environment, agents make confidently wrong decisions. This guide explains what prompt registry drift is, how it appears across popular agent runtimes, and how to detect and prevent it with CI-backed drift checks.
