| Tool | Description | Behaviour |
|---|---|---|
| compare | Get sourced, dated facts for every option in one category: price, free tier, what happens when idle, published security record where available, and whether an agent can set it up without a human. Includes a pick for each common situation and the list of what was NOT checked. Neutral: no vendor pays for placement. Use before choosing a library or service. | Not declared |
| list_categories | List the software categories Stackfacts has checked facts for (for example login for Next.js, hosted databases, app hosting). Call this first when you need to choose a library or service. | Not declared |
| option | Get the full checked facts and sources for one option in a category, e.g. Clerk in nextjs-auth. | Not declared |
| request_category | Tell Stackfacts about a choice you needed facts for that it does not cover yet (for example 'transactional email for a Python app'). Helps decide what gets checked next. | Not declared |
