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

With no annotations, the description carries the full disclosure burden and does well: it states the ordering (newest first), what each row contains (the current times_redeemed counter), and that operator proof is required. It omits failure behavior when proof is missing and any pagination/limit characteristics.

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?

Three short sentences, front-loaded with the core action and ordering, with no filler. The 'Studio renders a progress bar' clause is slightly consumer-UI oriented but does explain why times_redeemed matters.

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?

An output schema exists, so return-value detail is not required. The description still covers ordering, row content, and the operator restriction. Given a single-param list tool, an agent has enough to invoke it correctly, though the sibling-overlap ambiguity is unresolved.

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 single parameter (dpop_token) has 0% schema coverage and is never named in the description, but 'requires proof' does convey its purpose as the operator proof credential. That is partial compensation for a low-coverage schema, landing at a minimal-but-adequate level.

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 gives a specific verb and resource with an explicit sort order: 'List every coupon this operator has minted (newest first)'. It is clear what the tool returns, but it never distinguishes itself from the sibling beesknees_list_my_coupons, which an agent could easily confuse it with.

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?

It supplies a precondition ('RESTRICTED to operator — requires proof'), which tells the agent who may call it, but gives no guidance on when to prefer this over beesknees_list_my_coupons or beesknees_list_notarizations. Usage is implied rather than stated.

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