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 describes what the tool returns (external links with attributes) and its purpose, but doesn't mention rate limits, authentication requirements, pagination behavior beyond what's in the schema, or whether this is a read-only operation. The description adds some value but lacks comprehensive behavioral details.

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 appropriately sized with two sentences: the first states the purpose and return values, the second provides use cases. It's front-loaded with essential information and avoids unnecessary repetition. Every sentence adds value, though it could be slightly more structured.

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 (7 parameters, no output schema, no annotations), the description provides adequate purpose and usage context but lacks details about return format structure, error conditions, or behavioral constraints. It's complete enough for basic understanding but leaves gaps for a tool with this parameter count and no output schema.

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%, so all parameters are documented in the schema. The description doesn't add any parameter-specific information beyond what's in the schema, but it does provide context about what 'active outbound links' means. This meets the baseline expectation when schema coverage is complete.

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 with specific verbs ('Get active outbound links') and resources ('from a domain or URL'), and distinguishes it from siblings like 'get_active_backlinks' by focusing on outbound rather than inbound links. The description explicitly mentions what it returns and its use cases.

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 clear context for when to use this tool ('Useful for analyzing linking strategies, finding partnership opportunities, and auditing outbound link profiles'), but doesn't explicitly state when not to use it or name specific alternatives among the many sibling tools. It implies usage for outbound link analysis versus inbound (backlinks).

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