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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds value by disclosing returned content (description, repository, stars, category, README-derived features/tools/requirements, install config) and the conditional 'when known' qualifier on the install config.

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 states the action first, then the identifier, then the payload. No filler, and every clause carries information useful for a detail-fetch tool.

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?

With no output schema, the description bears full responsibility for describing return values, and it does so comprehensively, including the conditional install config. A minor gap is the lack of any error/not-found behavior, but the core content is complete.

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 the single slug parameter is already documented, and the description only repeats that it is a 'Socketlist slug.' It adds no format or syntax detail beyond what the schema provides, so the 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?

States a specific verb (Get) and resource (details for one MCP server) and enumerates the fields returned. The 'one MCP server by its slug' framing implicitly contrasts with the list-returning search_servers, though no sibling is named explicitly.

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?

Usage is implied by 'by its Socketlist slug,' and the schema notes the slug comes from search_servers, suggesting a lookup-after-search workflow. However, there is no explicit when-to-use/when-not guidance or named alternatives to distinguish it from search_servers or best_for.

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