Get or create a public token

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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=false and openWorldHint=true, so the mutation risk profile is covered structurally. The description usefully adds the per-shop rate limit (100 requests / 10 seconds) and clarifies the get-or-create behavior. However it never explains why the operation is destructive (e.g., whether token issuance revokes prior tokens) or what permissions are required, leaving the most consequential trait undisclosed.

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 with no filler. Minor issue: the italicized rate-limit note is front-loaded ahead of the actual behavioral sentence, which would be the more important lead for an agent deciding whether to call the tool.

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 should at least signal that the token lands in the owner-private receipt file; it leaves that entirely to the output_file parameter description. Combined with missing permission/prerequisite context for a destructive, non-idempotent operation, it is adequate but incomplete.

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 100%, and the schema already explains account, confirm, and output_file in detail (including the exclusive 0600 receipt file). The description adds no parameter-level detail, so the baseline of 3 applies.

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 states a specific resource and behavior: returns the shop's existing public token or creates one if absent. That 'get or create' semantics is precise and unambiguous. It does not differentiate from any sibling, though no sibling in the list clearly overlaps.

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 when-to-use or when-not-to-use guidance, no mention of alternatives, and no prerequisites for obtaining a token. The only operational context given is a rate limit, which is a constraint rather than guidance on selection.

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