I'm developing a tool called showsignature [critics wanted] A developer created showsignature, an open-source CLI tool that reduces token usage by 60% and increases task success rates when working with AI coding agents. The tool provides structural mapping and windowed file reading, and has been tested with Pi, Opencode, Codex, and Claude code. Hello Dev Community I'm developing a tool called showsignature I've been using it to develop itself since the beginning and I've use it on other projects tool, and just feels right. It started as specific tool I needed for a particular problem at the beginning, but it was so useful that I adopted it entirely in my code environment with other project, and I took features and added others depending on the need. I code mostly with Pi, but I've used Opencode, Codex and Claude code too, and is very useful there as well. The tools if fully open-source, and I believe it may be useful to other people too, specially in this times where tokes are becoming more and more expensive each time, and code bases grow and grow, with features here and there. It only has 4 dependencies commander, globby, typescript and zod. Here is a benchmark for those wondering if this tool is really useful: For me those results are very impressive because they represent a reduction on %60 token usage and increase in success rate for tasks. showsignature map OPTION ...
