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

With no annotations, the description must carry the full behavioral burden. It discloses that it returns setup files and remote MCP hops, and notes that task text is discarded. However, it does not state whether the tool performs external calls, requires authentication, is read-only, or has side effects. It also does not explain error behavior or what 'Task text' refers to precisely. This is a significant gap for a tool that may access remote resources.

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 two sentences with no filler. The primary purpose is front-loaded in the first sentence, followed by the output contents and a behavioral note. It is concise and well structured. The only minor issue is that 'Task text discarded' is a bit cryptic and could be clarified, but overall it is appropriately sized.

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?

The tool has 9 optional parameters but no output schema and no annotations. The description states what it returns but does not explain how parameters map to the result, which parameters are needed for a typical call, or any constraints or usage patterns. Given the complexity and lack of structured metadata, the description is insufficient for an agent to confidently invoke the tool with the right parameters.

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 every parameter is already documented in the schema. The tool description adds no extra meaning about parameters, such as which ones are commonly used together or how they influence the output. According to the rubric, with high coverage the baseline is 3, and the description neither enhances nor detracts from parameter understanding.

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 a specific verb ('Find') and a specific resource ('public pay-per-call tool gateway (Monid)'), and enumerates the returned items (CLI setup, how-it-works, skill file, remote MCP hops). This distinguishes it from sibling tools, which are about URL checks, calculations, or shape validation. No ambiguity or tautology.

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 gives no guidance on when to use this tool versus alternatives. It does not state prerequisites, conditions for selection, or situations where it should be avoided. The only behavioral note ('Task text discarded') is not about usage context. With 28 siblings, explicit routing would be valuable but is entirely absent.

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