+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds only that results come from 'actual' content with 'stable identifiers' but omits pagination behavior despite a cursor parameter and does not explain the limits of the read-only search.
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 a single sentence with no wasted words, but it is under-specified rather than appropriately concise. The vague terms 'actual' and 'stable identifiers' do not earn their place because they add little actionable meaning.
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?
An output schema exists, so return-value explanation is not strictly required. However, with seven parameters and only 29% schema coverage, the description should clarify filtering and pagination behavior but instead provides almost no operational context.
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 only 29%, so the schema leaves several parameters undocumented, and the description compensates for none of them. It does not explain the required query semantics, the type filter, limit, cursor, pathId, or locale constraints.
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 (Search) and resource (lessons and public library content), which is more informative than a tautology. However, 'actual lessons' is vague and the description does not distinguish this tool from the similarly named sibling academy_search.
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?
Provides no guidance on when to use this tool versus alternatives such as academy_search, academy_lessons, or academy_library. It also does not state any exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
