## Tools (3)

- `get_product_summary`: What users of one product struggle with: counts, the main problem areas, and the free-preview items per category (pain points, feature requests, workarounds, switching reasons) with their source links, plus the page and pricing links for the full list.
- `list_products`: List the software products that have a page on Friction, most-documented first, with counts of reports, themes and sources. Optionally filter by category slug and by a name or domain fragment.
- `search_items`: Search the free-preview feedback items of one product, optionally by category and by words in the title or summary (all words must match). Each item carries the source threads (URL, date, quoted excerpt, state) behind it.
