Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so the description carries the full load, and it does disclose useful behavior beyond the schema: the return payload (all availability and maintenance dates plus the Support Portal link) and the not-found fallback ('Suggests close names if not found'). It omits any note on permissions, rate limits, or result cardinality, which keeps it out of the top tier.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, zero filler, with the core purpose and payload front-loaded before the fallback behavior. Every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description correctly enumerates the returned fields, and even covers the failure path via suggested close names. Combined with 100% schema coverage on the lone input parameter, an agent has what it needs to invoke correctly; only permissions/edge-case details are absent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% for the single parameter, so the baseline is 3. The description adds value beyond the schema by clarifying that the value must be the exact PAM name and giving a concrete example format, which reduces invocation errors. It does not document any format edge cases, so it is not a 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource (retrieve one product version's full PAM record) and enumerates the contents: availability dates, maintenance dates, and Support Portal link. The example input format ('SAP NETWEAVER 7.5') makes the granularity unambiguous. It does not explicitly name or contrast itself with the sibling pam_search_products, so it stops short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'exact name as in PAM' implies this is for lookups where the name is already known, which indirectly contrasts with the fuzzy sibling pam_search_products. However, no alternative is named and there is no explicit when-to-use/when-not guidance, so usage is only implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
