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

With no annotations, the description must carry the safety profile, and it does state 'Free, read-only', which is a genuine behavioral disclosure. It also describes the pricing composition (seller price + fee.bps) and that settlement happens on devnet 36927. Gaps remain: pagination behavior for limit/offset and result-set shape are not described.

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?

It is a single compact paragraph, but it is a run-on that mixes this tool's behavior with downstream buy/pool/settlement mechanics, making it dense and hard to scan. The key purpose is front-loaded, which saves it from being worse.

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?

For a 7-parameter tool with no annotations and no output schema, the description partially compensates by enumerating returned per-agent fields (seller price, our price, cover, grade). But pagination semantics and the exact response shape are left unstated, so an agent must still infer some call details.

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 57%, so the schema carries much of the semantics. The description adds meaning for id ('id reads one entry') and status ('buy_now entries'), and the catalog_id convention, but says nothing about q, class, protocol, limit or offset beyond what the schema already provides.

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 opening clause states a concrete verb+resource ('Every hireable agent the coordination layer resells' at GET /v1/catalog) and adds scope detail ('id reads one entry'). It is reasonably distinguishable, but offers no explicit contrast with nearby listing tools like taifoon_discover or taifoon_offers, leaving the agent to infer the split.

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 gives one useful routing rule ('status buy_now entries are bought with taifoon_post_demand { catalog_id }') and mentions the cover comes from taifoon_pool_quote/post open. However there is no explicit when-to-use-this vs the many sibling discovery/hire tools, so guidance is only partial and implied.

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