context-window

Open-source transparent proxy for coding agents that preserves full conversation history on disk while selectively deciding what the model reads. Supports OpenAI-compatible, Anthropic Messages, and OpenAI Responses APIs, with setup docs, engine-specific configs, and benchmark claims for long-horizon agent sessions.

A Claude Code status line that shows session size, next-turn cost, and remaining budget before you type.

Local-first debugger for LLM agent context windows. It records each call’s context into a single-file trace so you can inspect, diff, and share what the model actually saw turn by turn.

CLI utility that counts LLM tokens in files or directories, with support for stdin, recursive scans, file-type grouping, profiles, JSON output, and multiple encodings.

ContextSpy is an LLM context profiler that intercepts agent traffic, breaks down token usage, and visualizes how prompts change across requests and sessions.

An open-source desktop client for editing LLM context with a separate AI model, context maps, compression tools, and revision rollback.
