ContextMeter – see what eats your coding agent context
Measure and trim the context your AI coding agent actually consumes
- Problem
- When project files get long, agents quietly start ignoring the bottom half; developers build tools to measure where AI coding context goes. Yet most devs have no idea which rule files, pasted snippets, or redundant context are wasting tokens and attention every session.
- Solution
- A local editor/agent plugin that breaks down a session's context into system prompt, rules files, open files, chat history, and tool output, highlighting duplicates and low-value blocks. It suggests one-click trims and estimates token savings.
- Users
- Heavy users of Claude Code, Cursor, and Codex, especially those mindful of monthly quotas
- MVP
- Capture context segment sizes and changes in local sessions; show category share and trend; detect repeated pastes, oversized rules files, unused tool output; generate a trimmed context block ready to paste; export a stats report
- Revenue
- Free basic stats; subscription for advanced analysis, history comparison, and team dashboards
- Why now
- Coding agents are now daily tools, making context budget a real cost, but developers currently manage it by feel and scattered tips
