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 one genuinely useful behavioral fact — that database row pages are included and carry a parentId — but says nothing about result volume, pagination, or whether the whole project tree is returned in one shot, which matters for a list tool on a potentially large project.

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 short sentences with the scope stated first and the row-page caveat second; nothing is wasted and the important inclusion rule is front-loaded. It is slightly thin rather than bloated, so it sits just below the top mark.

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 present, the description needn't explain return values, and one required param is fully documented in the schema. However, for a listing endpoint in a project with many pages, the absence of any pagination, ordering, or default-scope note leaves a real operational gap relative to the tool's likely complexity.

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% for the single projectId parameter, and the schema itself points to list_projects for discovery. The description only echoes the project scoping already documented in the schema, adding no format or constraint detail beyond it. 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?

States a specific verb (list) and resource (content pages and database pages) scoped to a project, and clarifies that database row pages are also returned with their parentId. This distinguishes it from get_page and query_page_database by scope, but it never names the obvious alternative list/search siblings, so the differentiation is implicit rather than explicit.

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?

The phrase 'for a project' implies the usage context (enumerate everything under a projectId), but there is no statement of when to prefer this over search_pages, get_page_database, or query_page_database, and no exclusions or prerequisites. The reader must infer the routing decision from the sibling list.

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