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

With no annotations provided, the description carries the full burden. It does disclose that the tool returns specific artifacts and that 'Task text discarded,' which is a behavioral note. However, it does not mention whether the tool is read-only, requires authentication, has rate limits, or any side effects. The statement 'Task text discarded' hints at input handling but is vague.

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?

The description is a single, front-loaded sentence with no filler. It states the core action and the key outputs immediately, and the 'Task text discarded' note is an efficient extra detail. There is no wasted text.

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?

Despite having 9 parameters and no output schema, the description provides minimal context. It lists four return artifacts but does not explain what 'Monid' is, how the parameters map to the lookup, or what an agent should do with the returned CLI setup and MCP hops. The presence of unrelated parameters (city, feed, json, etc.) is unexplained and could confuse an agent. The description is too sparse for a tool with this complexity.

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 the baseline is 3. The description adds no parameter-specific semantics—it does not mention any of the 9 parameters or how they relate to finding the gateway. The schema already documents each parameter, so the description adds no additional meaning beyond what's already structured.

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 clearly states the tool's purpose: finding a public pay-per-call tool gateway (Monid) and lists the returned artifacts (CLI setup, how-it-works, skill file, remote MCP hops). It distinguishes itself from the many sibling tools by focusing on this specific gateway lookup, though it doesn't explicitly name an alternative. The verb 'Find' and resource 'gateway' are specific.

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 guidance on when to use this tool versus alternatives. The description gives a purpose but does not mention any exclusions, prerequisites, or comparison with the 27 sibling tools. An agent would have to infer that this is for Monid-related lookups, but there is no clear when-to-use or when-not-to-use instruction.

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