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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful result semantics (only posts with a *pending* review, only those requested by teammates), but doesn't say whether results are ordered, paginated, or what fields come back.

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 short sentences, front-loaded with the definition, zero padding. Slight redundancy between 'asked... to review' and 'pending review', but that repetition reinforces the filter rather than wasting space.

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, annotated, single-optional-param read tool with no nested objects, the description covers what an agent needs to select and call it. Only minor gaps remain (result ordering, whether an empty list is normal), and no output schema exists to shift that burden.

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?

Only one optional parameter (limit) and schema coverage is 100%, so the schema fully documents range and default. The description adds nothing about the limit parameter, which is acceptable at this coverage level but means no value beyond the 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?

States a specific verb and resource ('List posts') with a precise scope: posts other teammates requested the authenticated user review. This distinguishes it implicitly from the many list_* siblings (list_drafts, list_recent_posts) by the 'pending review' filter, though it never names an alternative.

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?

'Use to see what's waiting on their approval' gives a use case, effectively implying this is a review inbox view. It does not mention when to prefer list_drafts, search_posts, or how it pairs with approve_post/send_back_post, leaving alternatives to inference.

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