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

There are no annotations, so the description carries the full burden, and it largely delivers: it discloses that the output is composed from the published record, includes IBM's exact words and page references, and notes which items only the customer's system can answer. It does not explicitly state whether the tool is read-only or has side effects, but the level of compositional detail is strong.

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?

The description is long but information-dense, using a colon-separated list to enumerate the plan's components rather than rambling. It front-loads the core purpose before the details, and every listed item adds value. It could be split into shorter sentences for scannability, but it is not padded.

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?

Even with no output schema, the description gives substantial detail about what the plan will contain, where the content comes from, and how items are linked. The main gaps are the lack of explicit return-format information and side-effect status, but those are minor relative to the richness provided. For a complex aggregation tool, this is largely complete.

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 description coverage is 100%, so the baseline is 3. The description adds meaning beyond the schema by stating the ordering constraint 'from an earlier catalogue release to a later one' and enumerating the release range. It does not redundantly re-document the parameters themselves, which is appropriate given the schema already covers them.

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?

The description defines a specific deliverable: a composed Maximo move/upgrade plan from a source release to a target release, enumerating the categories it contains. This clearly distinguishes it from more focused siblings like compare_maximo_versions or upgrade_checklist by emphasizing breadth and the published-record composition. The verb is implied by the tool name and title, but the resource and scope are exact.

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 description gives no explicit 'use when' guidance, prerequisites, or when-not-to-use instructions. With 18 sibling tools, the absence of any alternative routing is a real gap; usage is only implicitly conveyed by the tool's purpose. It never says what to use instead for a narrower comparison or a simple checklist.

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