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

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=false), and the description adds real behavior beyond them: cursor-based paging that 'never skips any', the newest-first ordering, and the concrete resume protocol with next_since/next_after_id/has_more. It stops short of mentioning auth, rate limits, or max page 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?

Front-loads the resource and ordering, then the paging protocol; every sentence carries information. The parenthetical field list and the dense paging sentence make it slightly heavier than ideal, but there is no filler.

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 no output schema, the description compensates by naming the returned fields and the cursor fields (next_since, next_after_id, has_more) an agent needs to page correctly, plus the REST equivalent. Nothing essential for correct invocation is missing.

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 coverage is 100%, so the baseline is 3, but the description goes further by explaining how since and after_id interact as a tie-broken cursor pair and how they must be reused together across pages — semantics the schema only partially implies. The limit/provider params get no additional treatment.

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?

Opens with a precise verb+resource ('Change log of provider data') and immediately enumerates the returned fields and ordering ('newest first'), so an agent can distinguish it from siblings like list_incidents or list_providers without opening any schema.

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?

Gives explicit conditional guidance: without 'since' returns the latest changes, with 'since'+'after_id' returns the oldest changes after the cursor, and describes the repeat-until-has_more-is-false loop. It does not name any alternative sibling tool or state when not to use this one, so it falls short of a 5.

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