Show HN: Is grep enough? A transparent benchmark for agentic code navigation

- The author benchmarks different approaches for letting an AI agent navigate large codebases: **grep** (simple text search), **bash** (shell commands), **LSP** (heavy industry-standard code intelligence), and **tree-sitter** (lightweight parsing library that understands code structure). - They ran 150 isolated tests across 10 major open-source projects (Bitcoin, Django, Rails, Redis, etc.) at 5 difficulty levels. - All scripts, Docker configurations, and transcripts are published for full reproducibility. - Why it matters: as AI coding assistants proliferate, the tools you give them to explore code (simple grep vs. structured parse trees vs. full language server) determine speed, accuracy, and complexity. This is a rare transparent comparison.
