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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description does not need to restate safety. It adds some behavioral context by indicating pagination and company scope, but it does not disclose filter behavior, ordering, or iteration semantics beyond what the schema implies.

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 very short and action-oriented, with no filler. The phrase 'GetListSchedules' is redundant with the tool name and reads like code rather than natural prose, but the overall structure is scannable and front-loaded.

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 output schema covers return shape, and annotations cover safety, so the description does not need to explain those. However, it omits guidance on filtering by status, how pagination tokens work, and when this list should be used instead of fetching a single schedule. It is adequate but has clear gaps.

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 only 25%, with only companyId described as a 'UUID value wrapper.' The description adds minimal parameter meaning beyond the word 'pages through,' which hints at pageSize/pageToken but does not explain filter.statuses, required parameters, or pagination conventions. The schema helps via enums and bounds, but the description does not compensate for the low coverage.

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 states a clear verb ('pages through') and resource ('a company's schedules'), making the tool's function obvious. It does not explicitly differentiate from accounting_get_schedule or other schedule-related siblings, but the plural list semantics are reasonably clear from the name and description.

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 guidance on when to use this tool versus accounting_get_schedule, accounting_create_schedule, or accounting_cancel_schedule. The only hint is the pagination framing, which implies a list operation, but no alternatives or conditions are stated.

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