This article explores two primary strategies employed by AI coding agents: 'Eager Hydration' and 'Just-in-Time Search'. Eager Hydration, seen in tools like Cline and Aider, involves providing the model with extensive repository information upfront, either a full file listing or a curated map, to reduce latency and improve context. Just-in-Time Search, used by agents like Claude Code, Gemini, and Codex, relies on the model actively searching for relevant files and information as needed, which testing suggests can be more effective for finding specific issues. AI
IMPACT The choice between eager context loading and just-in-time search significantly impacts AI coding agent performance, affecting token costs, latency, and the accuracy of the agent's understanding of a codebase.
