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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not mention whether the operation is read-only, whether authentication is required, what the response shape is, or any side effects. The phrase 'Blogger profile: followers, posts' hints at the data returned but provides no behavioral detail.

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 extremely short, but this is under-specification rather than concise efficacy. It lacks essential information and reads like a fragment. While brevity is generally good, here it omits the core functional statement and any parameter/behavior context, so it earns a low score.

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 an output schema, the description fails to explain the tool's purpose, the meaning of the single parameter, or any usage context. For a tool with one optional parameter and a sibling list full of similar content platforms, the agent cannot confidently construct a correct invocation. The definition is severely incomplete.

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 schema has one parameter 'q' with a default of '', and schema description coverage is 0%. The description completely ignores 'q' and does not explain its meaning, format, or constraints. The description adds no semantic value to the parameter, leaving the agent to guess what 'q' represents (e.g., a username, query string).

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 'Hashnode: Blogger profile: followers, posts' essentially repeats the tool name and then provides a noun fragment without any verb or action. It indicates the subject matter (Hashnode blogger data) but does not explicitly state what the tool does (e.g., retrieve, fetch, search). It is closer to a tautology than a clear functional statement, and does not meaningfully distinguish itself from siblings like devto or medium beyond the name.

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 guidance on when to use this tool, when not to use it, or what alternatives might be better for similar tasks. The description offers no context about selecting this over the many sibling tools (devto, medium, etc.). This is a complete absence of usage guidance.

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