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 elsewhere. The description adds useful context by naming the returned fields and implying a recency window, but says nothing about ordering, default page size, or how far back 'recent' reaches.

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?

A single short fragment with zero waste and the key noun front-loaded. It is efficient, though the missing verb makes it slightly less self-explanatory than it could be at the same length.

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 four optional params, no output schema, and a read-only annotation set, the description does partial duty by naming returned fields in place of a return schema. It still omits pagination behavior, default ordering, and the recency window, which an agent needs to interpret results correctly.

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 page, status, operation and organizationId are already documented in the schema. The description's mention of status/caller/cost loosely maps to the status filter but adds no format, default, or interaction detail beyond structured data — baseline 3 applies.

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 identifies the resource (recent operation call logs) and the fields returned (status, caller, cost), but it is a noun phrase with no verb and no scoping. It does not distinguish this from siblings like search_ops or call_op, which an agent could easily confuse with a log-listing tool.

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?

There is no guidance on when to use this versus search_ops or call_op, no mention of prerequisites, and no statement of what it excludes. The only hint is the word 'recent', which implies a bounded window but never states it.

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