list_sets

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

No annotations are provided, so the description carries the full burden. It reveals caching behavior ('cached for hours') and normalization, which is useful transparency. However, it doesn't disclose pagination, ordering, or whether this is a read-only operation, which for a 0-param list tool is a moderate gap.

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?

A single sentence that conveys purpose, caching behavior, and normalization in concise form. Efficient and front-loaded, though it could use a sibling note to differentiate from search_sets.

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?

This is a simple 0-parameter list tool with an output schema. The description covers purpose and caching. However, given the large sibling cluster of set-related tools (search_sets, get_set, get_set_cards), it should clarify what 'normalized' means and how it differs from search_sets to be fully complete.

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 tool has 0 parameters and no schema properties to document. The description's scope is entirely complete for the parameter dimension since there's nothing to elaborate on. Baseline 4 for 0-param tools is appropriate.

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 it lists PokéWallet sets, which is a specific verb+resource. However, it doesn't distinguish from the sibling 'search_sets' or 'get_set' tools — a user may not know the difference between 'list' and 'search' for sets without more clarification.

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 description says 'normalized' sets are listed and results are cached 'for hours', which hints at recency behavior, but gives no guidance on when to use this vs search_sets or get_set. There's no explicit when-to-use or when-not-to-use guidance.

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