Get External Links

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 disclosure and falls short. 'Get' implies a read, but nothing is said about permission requirements, whether the sample is capped, or how pagination behaves in practice; only the word 'samples' hints at a bounded result set.

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 front-loaded sentence with no filler. The verb and resource lead, and the parenthetical earns its place by disambiguating 'external links'.

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?

An output schema exists so return values need no explanation, and all four parameters are documented in the schema. What is missing is the operational context an agent needs to choose this tool over get_external_links_history, which the description never addresses.

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 (limit, offset, host_id, user_id) is already documented in the schema, and the description adds no format or interpretation details. Baseline 3 applies when the schema does the heavy lifting.

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?

Clear verb ('Get') plus resource ('external links (backlinks)') with a clarifying parenthetical that resolves the term for an agent. The word 'samples' hints at a scoped subset, but the description never distinguishes this tool from the sibling get_external_links_history, leaving their boundary to inference.

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?

No statement of when to use this tool versus get_external_links_history or any other sibling, and no prerequisites or preconditions given. The agent must guess that 'samples' means a small illustrative set rather than a full/historical listing.

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