Tools
| Tool | Description | Behaviour |
|---|---|---|
| estimate_ai_cost | Estimate the monthly cost of running a prompt on current AI models (Claude, GPT, Gemini, DeepSeek, Qwen and others), from thinkhard.si's price catalog, which is checked against each provider's pricing page. Give token counts, or paste the prompt text to estimate them. | Read-only |
| get_prompt | Get the full text of one prompt from the thinkhard.si repository by its slug, registry number (such as CAR-001) or title, with its {{blanks}}, what goes in each, and why it works. Pass values to fill blanks with the user's details. Ask the user for any blank you cannot fill from the conversation instead of inventing it. | Read-only |
| grade_prompt | Score a prompt out of 10 on the ten checks thinkhard.si uses (what to make, who it is for, background facts, length, format, what to avoid, what good looks like, an example, what to do if unsure, layout for the model). Returns which checks pass and a plain question for each one that fails. Rule-based and instant; use it to see what a prompt is missing before improving it. | Read-only |
| list_collections | List the collections in the thinkhard.si prompt repository, with how many prompts each has. | Read-only |
| search_prompts | Find ready-made, expert prompt templates for a work task in the thinkhard.si repository (300+ prompts for email, meetings, presentations, job search, marketing, sales, support, HR, finance, legal, spreadsheets, research and more). Use it whenever the user wants to write, plan, summarize, analyze or draft something at work, before writing a prompt from scratch. Then call get_prompt with the slug. | Read-only |
