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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so safety is covered. The description adds genuine behavioral context beyond that: results are paginated ('one page') and certain fields are omitted ('Excludes descriptions and private notes'), which helps the agent interpret the return payload. It still omits pagination defaults and response shape details.

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 with zero waste, and the core action is front-loaded before the field-exclusion caveat. Nothing is redundant or 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?

The tool has four undocumented parameters and no output schema, so the description should explain more about pagination defaults and the shape of returned catalog entries. It does note that descriptions and private notes are excluded, which is useful, but the overall picture is only minimally sufficient for correct invocation.

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 0% across all four parameters, so the description carries the full burden of explaining them. It only hints at pagination via 'one page' and says nothing about page, count, sortDir, or the fixed sortField='createdAt', leaving the parameters effectively undocumented.

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 ('Read one page') and resource ('class catalog and categories'), which clearly distinguishes it from the get_* siblings that return single entities. However, it does not differentiate itself from the sibling fitssey_list_courses, leaving an ambiguity about classes vs. courses that an agent must resolve elsewhere.

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?

'Read one page' implies paginated browsing of the catalog, which is adequate implied usage. But there is no explicit guidance on when to use this versus list_courses or the schedule tools, and no exclusions or prerequisites are named.

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