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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety is covered. The description adds useful context that approval requirements are organization-configurable and that business workflow approvals always apply, but it does not explain media behavior, permissions, or error conditions in depth.

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?

Three sentences, appropriately sized and mostly front-loaded toward usage context and purpose. The approval sentence earns its place, though the opening context sentence is somewhat generic.

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 an output schema and rich annotations present, the description does not need to explain return values. However, it leaves gaps around selecting this tool versus list_daily_logs and around the meaning of the dailyLogId parameter, so it is only adequately 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?

There is one required parameter, dailyLogId, and schema description coverage is 0%, so the description should compensate. It says only "Read a daily log" and never explains that the parameter is a UUID identifying a specific daily log, adding no meaning beyond the schema's type and format.

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: "Read a daily log and its media." This clearly identifies the operation, though it does not explicitly distinguish itself from siblings such as list_daily_logs or update_daily_log.

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?

Provides a broad usage trigger ("Use this when working with RetailHardHat field_operations records in the connected organization"), but does not say when to use this instead of list_daily_logs, update_daily_log, or other daily log tools. The guidance is implied rather than explicit.

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