Grep beats LSP? Why coding agents ignore your fancier tools

https://www.agentconnect.md/assets/blog/grep-lsp-harness/04-semantic-tool-use-by-task.svg
A study compared lexical search with grep against LSP-backed semantic navigation for coding agents, finding that while semantic navigation was more precise, it sometimes reduced task success due to unfamiliarity and context limitations. The results suggest a broader engineering problem where models use tools in isolation rather than through a harness that defines available actions and context.
