+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds essentially nothing beyond the annotations – it does not explain what the returned "slot document" contains, what the "template catalog" scope is, or any access requirements. It does not contradict the 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?
A single short sentence with no waste and the action front-loaded. Efficient, though the brevity comes at the cost of substance rather than being paired with it.
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 values need not be described, and the read-only behavior is covered by annotations. Still, for a retrieval tool the description leaves key ambiguity about what is being fetched and how workspaceId scopes the result, making it only minimally adequate.
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 50%: projectId is described only as "UUID string" (a type restatement) and workspaceId has no description at all. The prose mentions neither parameter and adds no meaning about how projectId or workspaceId scope the read, so it fails to compensate for the coverage gap.
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 ("Read") and two resources ("carousel slot document" and "named template catalog"), so the basic operation is clear. However, the terms "slot document" and "template catalog" are ambiguous, and the description offers no differentiation from siblings like carousels_preview, carousels_compile, or carousels_expand_recipe, which also operate on carousel documents.
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?
There is no guidance on when to use this tool versus the many other carousels_* siblings (preview, compile, migrate, clone). No preconditions or context for invocation are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
