seo_audit_internal_links

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

Annotations already provide readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds value by explicitly calling it a 'Safe, read-only link graph analysis' and stating 'No file modifications,' reinforcing and slightly extending the annotations. No contradiction found.

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 well-structured with a concise overview followed by brief usage and behavior sections. Every sentence adds actionable information with no filler or repetition of the schema.

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 single-parameter, read-only audit tool with rich annotations, the description adequately covers what the tool does and how it should be used. It does not detail the exact return format, but no output schema is expected and the described outputs (anchor text, orphan flags, link suggestions) sufficiently imply the shape of results.

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% and the single target parameter is already well documented in the schema. The description does not add parameter-specific detail beyond the schema, which is acceptable; baseline 3 applies.

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 opens with a specific verb ('Audits internal linking structure') and enumerates concrete capabilities: identifying generic anchor text, flagging orphan pages, and suggesting contextual links. This clearly distinguishes it from the other seo_audit_* siblings without needing to open their schemas.

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?

It has an explicit USAGE GUIDELINES section that states when to use the tool ('improve PageRank flow, internal topic clustering...') and an explicit exclusion with a named alternative ('Do NOT use to inspect external backlink profiles; use seo_suggest_related_ecosystem'). This is ideal routing guidance.

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