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. The description adds value by disclosing that the result is URLs rather than file bytes, which prevents a wrong assumption about the return type. It does not cover error behavior for an unknown slug or URL expiry.

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, zero redundancy, with the core action first and the key caveat second. Nothing extraneous.

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 no output schema, the description correctly discloses the return shape (download URLs). For a single-parameter read tool with rich annotations, that is nearly sufficient; the remaining gap is the undefined slug semantics.

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?

Only one parameter exists and schema description coverage is 0%, so the description carries the burden for 'slug'. It confirms the lookup is by slug but never defines the slug format or where it comes from (presumably search_templates results), and no maxLength context is given. Partial compensation only.

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 ('Get') and resource ('one template kit') and scopes it by slug, which implicitly separates it from the list/search siblings. It stops short of naming shareout_search_templates as the alternative, so differentiation is inferential 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 clause 'Returns download URLs, not file contents' tells the agent what to expect and implies a follow-up download step, which is useful usage context. However, there is no explicit statement of when to call this versus shareout_search_templates or shareout_get_document.

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