I got 30% better AI coding results

CodeSlimmer v2.2, a new open-source tool by developer akasula09, converts local codebases or public GitHub repositories into a single LLM-ready text file with token estimation and directory mapping, claiming to improve AI coding results by 30%. The tool supports AI models including Claude 3.5, Gemini 3.1 Pro, GPT-4o, and DeepSeek R1, and is installable via pip. It features remote GitHub URL support, cross-platform clipboard integration, overwrite safety, ASCII directory trees, XML output, token estimation, and smart file size formatting.

Safely convert local codebases or public GitHub repos into clean, LLM-ready context with token estimation and directory mapping. CodeSlimmer packs any code repository—whether stored on your local machine or hosted on GitHub—into a single text file structured specifically for AI models like Claude 3.5 , Gemini 3.1 Pro/3.6 Flash , GPT-4o , and DeepSeek R1 . - 🌐 Remote GitHub URL Support: Pass any public GitHub URL https://github.com/user/repo https://github.com/user/repo to fetch, extract, and slim repositories directly—zero git required. - 📋 Cross-Platform Clipboard Integration: Instantly copies output directly to your system clipboard Windows, macOS, or Linux . - 🛡️ Overwrite Safety: Inspects signature headers to ensure local files are never overwritten accidentally. - 🌳 ASCII Directory Tree: Builds a visual project structure map at the very top of your context output. - 🏷️ LLM-Friendly XML Output: Encloses code in clear <file path="..." tags for max prompt accuracy. - 📊 Token Estimator: Estimates context size ~4 chars/token and checks capacity against major models. - 📏 Smart File Sizes: Calculates and formats physical sizes B , KB , MB , GB . Install CodeSlimmer using pip : pip install code-slimmer Clone the repository and run the script directly: git clone https://github.com/akasula09/codeslimmer.git https://github.com/akasula09/codeslimmer.git cd codeslimmer If installed via pip : codeslimmer If running directly from source: python codeslimmer.py CodeSlimmer supports two distinct input modes: Enter a relative or absolute local folder path. CodeSlimmer creates ai context.txt inside that folder and offers an optional clipboard copy. An example is below. --- CODE SLIMMER v2.2 --- Enter a local folder path OR a GitHub URL: my project folder 📄 Loaded rules from .gitignore --- SUCCESS --- Packed 12 code files.
