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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds genuinely new context: the default filter is pending, and mutation of approvals is out of scope for this tool. It omits ordering, result size, and pagination behavior.

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?

Two compact sentences with zero filler, leading with the resource and default scope before the exclusion. Every clause carries usable information.

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 single-optional-parameter read tool with full annotations and no output schema, the description covers scope, default, and the out-of-scope action. A brief note on what an approval entry contains (or ordering) would close the remaining gap.

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 0% and the schema has no default keyword, so "pending by default" supplies real information the schema lacks about the sole status parameter. It still says nothing about what each enum value returns or how 'all' differs behaviorally from omitting the parameter.

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?

Names the specific resource (the org's approval queue) and its contents (publish requests and other actions awaiting a human), which no sibling tool covers. The implicit verb is 'list' rather than an explicit one, and sibling differentiation comes only from the resource being unique, not from stated contrast.

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?

"Approving happens in the app, not here" is an explicit when-not that prevents an agent from hunting for an approve action. "(pending by default)" signals the default state, but nothing tells the agent when to choose status=approved/rejected/all versus leaving it unset.

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