WHY THIS EXISTS

A practical niche tool, not a generic text box

Plan an LLM context window before it overflows. Estimate system, history, retrieval, pasted prompt, output buffer, remaining turns, and approximate cost. The output is intentionally broken into visible signals so a user can improve the input, rerun the check, and understand what changed.
