Tool usage guide

Learn when to use this tool, what it supports, and how real users apply it.

Overview

This hub brings together the steps that happen around a prompt before it is sent to a model: rewriting a rough instruction into a clearer structure, estimating token usage and cost, translating prompts for multilingual use, preparing clean grounding text, checking inputs for prompt-injection risk, and understanding the language, data, or expressions a prompt references.

When to use

Prompt work is rarely just writing one line: you usually iterate on clarity, check length and cost, and review the input for safety before sending it.
Comparing a prompt rewrite, a token estimate, and an injection scan side by side helps you ship a prompt that is both cheaper and safer to run in production.
It groups the small preparation tasks that sit between a rough idea and a reliable LLM call, so you can finish the full input-prep loop without bouncing between unrelated pages.

FAQ

What does 'LLM input preparation' mean here?

It covers the work that happens before a prompt reaches the model: structuring and clarifying the instruction, estimating token usage and cost, translating or detecting the input language, cleaning source text to ground the answer, and checking for prompt-injection risk.

Will these tools rewrite my prompt automatically?

The Prompt Optimizer scores clarity, completeness, and ambiguity, then rewrites the instruction into Role, Task, Constraints, and Few-shot sections, with an optional AI-assisted rewrite for a stronger version.

Which token providers are supported?

The AI Token Estimator reports OpenAI, Codex, Claude, and DeepSeek profiles, and labels each estimate as exact-offline-tokenizer, official-provider-API, or heuristic so you know how much to trust it.
