Critical gaps across both tools. The 'add' tool is a placeholder with no business value. The 'search_ebay_items' tool has a functional description but lacks parameter descriptions entirely (both 'query' and 'limit' have null descriptions). Output is unstructured plain text (response.text) rather than parsed JSON with typed fields. No error handling guidance for LLMs, errors are raw strings without recovery hints. No pagination support despite potentially large result sets. Tool composition is weak: no batch operations, no idempotent guarantees documented.

Search items on eBay using Browse API
Parameter descriptions are null for all inputs. 'query' and 'limit' in search_ebay_items lack any guidance on format, constraints, or purpose. LLMs cannot infer whether 'limit' accepts 1 - 100, 1 - 1000, or unbounded values.
Output is unstructured plain text (response.text from eBay API). No schema documented. LLMs cannot parse results reliably or extract item IDs, prices, or links for downstream operations. Should return structured JSON with typed fields: items[], total_count, next_cursor.
Error responses are raw strings without recovery guidance. 'eBay API request failed with status code 401: ...' tells the LLM nothing about whether to retry, ask the user, or check credentials. Should categorize errors and suggest next steps.

No pagination support. If eBay returns 100+ items, the entire response is dumped into context, wasting tokens and degrading LLM reasoning. Should accept page/offset and limit, return total_count, and cap results at 20 - 50 items.
The 'add' tool is a placeholder with no eBay domain relevance. It inflates tool count and adds noise. Remove it or replace with a meaningful utility.
