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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions '[requires credits]', which adds some context about resource usage, but it doesn't cover other critical aspects such as whether this is a read-only or mutation operation, potential rate limits, error handling, or output format. For a tool with no annotations, this is insufficient.

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 concise and front-loaded, stating the core purpose in a single sentence with an additional note in brackets. There's no wasted verbiage, and it efficiently communicates the essential information, though it could be slightly more structured for clarity.

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?

Given the complexity (a generation tool with 3 parameters) and the absence of both annotations and an output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., the structure of generated tags), potential side effects, or error conditions. This leaves significant gaps for an AI agent to understand the tool fully.

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 description coverage is 100%, meaning all parameters are documented in the input schema. The description doesn't add any meaningful semantic information about the parameters beyond what's already in the schema (e.g., it doesn't explain how 'title' and 'content' are used to generate the meta tags). This meets the baseline for high schema coverage.

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: 'Generate meta title, description, and Open Graph tags from content'. It specifies the verb ('generate') and the resources/outputs (meta title, description, Open Graph tags). However, it doesn't explicitly differentiate from sibling tools like 'seo_schema' or 'seo_score', which prevents a perfect score.

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 provides minimal usage guidance. It mentions '[requires credits]' which hints at a cost or resource constraint, but it doesn't specify when to use this tool versus alternatives like 'seo_schema' or 'seo_score', nor does it provide context about prerequisites or typical scenarios for application. This leaves significant gaps in guidance.

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