Action Summary

ctxlens is a command-line tool that analyzes token usage in codebases to help developers manage AI model context limits. It automates tasks like calculating token budgets, identifying high-token files, simulating optimizations, and monitoring token usage in real-time. Fully offline and privacy-focused, it provides insights across multiple AI models, enabling better decision-making for fitting codebases within context windows.

What’s Changed

Minor

  • Cost estimation — --cost flag on scan/budget estimates per-request pricing from the model registry
  • Config-level exclude — .ctxlensrc/package.json can now set default exclude patterns
  • Include/exclude on all commands — consistent --include/--exclude flags across scan, budget, diff, optimize, watch
  • Clarified tokenizer accuracy in docs — Claude counts are approximations (tiktoken-based)
  • Added CI workflow, repo metadata, README badges
  • Added Dependabot config (monthly, targeting dev)
  • Dependency bumps: vitest 4.1.3, esbuild 0.28.0, actions/setup-node 6, actions/checkout 6
