Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple alias with 2 params, 1 required, and an output schema, the description fully covers what an agent needs: behavior, safety, parameters, return format, and usage guidance. The output schema exists, so return values need not be detailed further. The only minor gap is a precise definition of session_id semantics beyond 'filters results', but the alias relationship to search_hipocampo mitigates this.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
