### Introduction
Software engineers often waste precious minutes hunting for code snippets they’ve already written, only to rediscover the same logic elsewhere in a repository. A new open‑source utility called **Capn‑hook** aims to eliminate that repetitive grunt work by automatically detecting and blocking duplicate code searches before they even start. Launched on GitHub earlier this month, the tool has already sparked discussion on Hacker News, where early adopters praise its simplicity and immediate impact on daily workflows.

### Key Developments
Capn‑hook operates as a lightweight Git hook that integrates with popular IDEs and command‑line interfaces. When a developer initiates a search—whether via `grep`, `rg`, or an IDE’s built‑in find‑in‑files feature—the tool checks a local hash‑based index of previously queried patterns. If the search term matches an entry logged within the past 24 hours, Capn‑hook intercepts the request, returns a concise message indicating the query’s redundancy, and suggests re‑using the existing result instead of re‑scanning the codebase.

The project’s README highlights three core benefits: reduced CPU usage on large monorepos, faster feedback loops during debugging, and encouragement of better documentation practices as teams begin to log useful search patterns. Initial benchmarks shared by the maintainer show an average 18
