Something I expected is not there

A product disappeared

Check whether it is archived - archived products drop out of the lists you scan daily and keep everything they had. Filter by status to see them, and restore_product brings one back.

If it was deleted, delete_product is a soft delete and restore_product still works. purge_product is the irreversible one, and it is a separate act that an agent can never perform.

An agent reports a product it cannot find

Most often it is in a different workspace. Tools resolve against a workspace, and a token scoped to one will not see another's products. get_workspace_overview shows what the caller can actually reach.

A section of the context package is empty

get_product_context names what it left out. A section omitted because the caller lacks the scope for it is listed in missing with the reason - so an empty section and a withheld one are distinguishable, which is the point.

An answer looks truncated

The context package works to a token budget and says when it trimmed. Ask for a specific section directly if you need all of it, or use the cursor on the underlying list tool.

Search finds nothing

Keyword search matches text. If you are looking for a concept rather than a phrase, use mode: "semantic", which matches on meaning and follows one hop through record links. It costs a credit, and it says honestly what it covered - it never quietly falls back to keyword matching and presents the result as semantic.
