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

The annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is clear. The description adds useful context that collections are curated starter kits and that a slug returns the commands within one, but it does not cover pagination, return format, or other behavioral details.

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, front-loaded sentences with no wasted wording. The examples are compact and directly support understanding of what a collection is.

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 read-only tool with one optional parameter and annotations covering safety, the description covers both modes of use adequately. It could be slightly more explicit about the default list behavior when no slug is provided, but no critical information is missing.

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%, so the slug parameter is already documented in the input schema. The description reinforces its meaning by explaining that a slug retrieves commands in a specific collection, but adds no syntax or format details 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?

The description identifies the resource as curated collections, gives concrete examples, and explains the dual behavior: listing collections by default and returning commands when a slug is supplied. It is clear what the tool does, though it does not explicitly differentiate itself from sibling tools such as search_commands or list_communities.

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 optional slug parameter, but it does not state when to call this tool instead of alternatives like search_commands or trending_commands. Usage is inferable but not explicitly guided.

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