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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds that the tool returns drafts, templates, and evergreen content, which is useful, but it does not disclose pagination behavior, default limits, or team-scope semantics. No contradiction with annotations.

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?

The description is two short sentences that front-load the core action and return types. No unnecessary details or repetition, making it highly efficient and well structured.

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?

Given the simple list operation and rich schema/annotations, the description is adequate but not complete. It omits details like default limit (20), pagination, and team_id scope behavior, which are only in the schema. The mention of returning all three content types might also slightly mislead without noting the type filter.

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%, with each parameter (type, limit, search, team_id, category) adequately described in the schema. The description adds no extra parameter-level meaning, so the baseline score of 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 clearly states that the tool lists saved content from the library and identifies the content types returned (drafts, templates, evergreen). It uses a specific verb and resource, and while it doesn't explicitly contrast with sibling tools like get_library_item, the list-versus-single distinction is evident.

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 description implies when to use the tool ('List saved content from your library') but provides no explicit guidance on when to prefer this over get_library_item or other list tools. No exclusions or alternative suggestions are given, so usage context is only implied.

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