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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that attached photo metadata is included and that approval requirements may apply, but it does not explain pagination, filtering behavior, or what approvals mean in practice.

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 short and mostly front-loaded around reading daily logs, with no wasted detail. The opening context sentence and approval sentence are slightly boilerplate, but the overall size is appropriate for a simple list tool.

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?

For a simple read-only list tool with rich annotations and an output schema, the description covers purpose and some return context. However, it omits the required siteId scoping and pagination/search parameters, which are important for correct invocation despite being present in the schema.

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%, and the description mentions none of the four parameters. It does not explain that siteId is required, nor what limit, offset, or search do, leaving an agent to infer all parameter semantics from an undescribed schema.

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 gives a clear verb and resource: 'Read field daily logs, including attached photo metadata.' It is distinguishable from create/update/delete siblings by the read framing, but it does not explicitly distinguish list_daily_logs from get_daily_log, which is the closest sibling.

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 'Use this when working with RetailHardHat field_operations records' is broad context rather than actionable guidance. It does not say when to use this list tool instead of get_daily_log, nor does it explain filtering or pagination use cases; the approval note is not usage guidance for selecting this tool.

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