mcp_enrich_bib_entry

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

The description mentions 'scraping metadata' but does not disclose side effects like network requests, failure modes, or whether the entry is modified. No annotations are provided, so the description carries full burden but fails to inform about behavior beyond basic operation.

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 short and front-loaded with the purpose. The Args section is well-structured. No superfluous text, though the Returns line could be integrated. Minor improvement possible.

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 presence of an output schema and four parameters, the description covers the basic purpose and parameters but omits context like why to use scraping, error behavior, or relationship to the sibling tool. Adequate but with gaps.

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 description lists each parameter with a brief explanation and an example for arxiv_id. However, it does not clarify optionality, interdependencies (e.g., if multiple identifiers are provided), or default behavior. Schema coverage is 0%, so description partially compensates but lacks completeness.

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 states 'Enrich a bibliography entry by scraping metadata,' which clearly identifies the action and resource. It implies distinction from the sibling tool 'mcp_enrich_bib_file' by focusing on a single entry. However, it does not explicitly differentiate from the sibling.

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 guidance is given on when to use this tool versus the sibling or when not to use it. There is no mention of prerequisites, contexts, or alternatives.

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