analyze_meta

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

With no annotations at all, the description carries the full burden, yet it does not disclose what 'analyze' actually does — whether it fetches the URL live, what properties it evaluates (length, presence, duplicates), or whether any auth/rate limits apply. It adds nothing beyond the name.

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?

A single short sentence, front-loaded with the verb and resource. It is efficient, though arguably too terse to be informative rather than genuinely optimal.

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 tool with no annotations, no output schema, and an undocumented parameter, the description should explain what the analysis returns or which aspects are evaluated. It leaves the agent unable to predict the result shape or behavior.

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?

There is one required parameter with 0% schema description coverage; the schema only declares 'url' as a uri format. The description's phrase 'of a webpage' loosely implies the url target, but adds no syntax, format, or constraint detail beyond the schema.

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?

States a specific verb ('Analyze') and resource ('meta description of a webpage'), which is clearer than a bare tautology. It does not explicitly distinguish itself from siblings like analyze_title or analyze_open_graph, but the resource noun is specific enough that an agent can differentiate it.

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 when-to-use guidance, no stated prerequisites (e.g., whether the page must be fetched first), and no mention of alternatives among the many analyze_* siblings. Usage must be inferred entirely from the name.

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