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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It states the output is a 'full canonical record' and includes version history, but does not mention that the tool is read-only, idempotent, or any security/permission requirements. This is insufficient for safe invocation.

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, concise sentence with no fluff. It front-loads the key information ('Full canonical record') and avoids redundancy. However, it could be slightly more structured by separating the record from version history without adding length.

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 low complexity (1 parameter) and the presence of an output schema, the description adequately conveys the output nature but fails to explain the input parameter clearly. It is functional but not fully self-contained, missing usage context that would compensate for the missing schema descriptions.

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?

The input schema has 0% description coverage for the single required parameter (sweets_id). The description adds no explicit explanation of this parameter; the phrase 'for one sweets shop / bakery' only indirectly implies the ID parameter's role. An explicit mapping would improve semantic clarity.

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 the tool retrieves a full canonical record and version history for one sweets shop or bakery, which aligns with the tool name and specifies the resource type. It differentiates from sibling tools by category and specificity to a single record rather than search results.

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?

No guidance is provided on when to use this tool versus alternatives. For example, it does not contrast with search_sweets_by_text for searching or other get_*_details tools for different categories. This omission forces the agent to rely on tool name alone for disambiguation.

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