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

With no annotations, the description carries the full burden, and it does disclose a genuine behavioral trait: that payments_accepted reflects whether the deployment has an x402 facilitator, and that without one every wall returns HTTP 402 with terms. It says nothing about auth, pagination, or side effects, so it is only partially transparent for a read tool.

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 sentences, front-loaded with the resource definition. The second sentence is dense and parenthetical, but nothing is decorative and the key fact (payment state is in the payload) is stated plainly.

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?

No output schema and no annotations, so the description must be self-sufficient. It hints at the returned fields but omits the effect of the status filter and any auth or pagination behavior, leaving modest gaps for a simple single-parameter catalog listing.

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 coverage is 100%, so the enum and default LIVE are already documented. The description does not mention the status filter at all, and its phrase 'every skill' arguably obscures that the default view is LIVE-only; baseline 3 applies since 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?

It states a specific resource (the skills catalog) and enumerates what each entry contains: quoted price, rails, status. That is concrete, but it never distinguishes itself from sibling listing tools like taifoon_grid_prices, taifoon_offers, or taifoon_landscape, so the agent must still guess which catalog it wants.

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 explicit when-to-use, when-not, or named alternative. The only usage signal is implicit ('the skills catalog') and the aside about payments_accepted, which describes output rather than telling the agent when to reach for this tool.

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