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. The description adds genuinely useful context with the 100 req/10s rate limit, but leaves the destructive flag unexplained — it never says whether minting a token invalidates or rotates an existing one, which is exactly the risk an agent needs to know.

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 tight sentences with no filler. The only structural nit is that the rate-limit line leads, pushing the actual purpose into second position rather than front-loading 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?

There is no output schema, so the description should carry more of the return story, but it only says a token is returned without describing its form or use. Combined with the unexplained destructive behavior, this is adequate but with visible gaps for a tool that both reads and mutates.

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%, so account, confirm and output_file are already well documented in the schema. The description adds no parameter-level meaning beyond that, which is the expected baseline when the schema does the heavy lifting.

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 clear verb+resource pair: it returns an existing public token for the shop or creates one when none exists. No sibling tool deals with public tokens, so there is no ambiguity to resolve, though it never explicitly distinguishes itself from the surrounding get_* tools.

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 get-or-create behavior is described, but there is no guidance on when an agent should call this versus alternatives, no prerequisites, and no explanation of the confirm flag's role (left entirely to the schema). The rate-limit note is contextual, not usage direction.

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