documents_info

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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'Get info' implies a read-only operation, it doesn't specify whether authentication is required, rate limits apply, what information is returned, or how errors are handled. This is inadequate for a tool with zero annotation coverage.

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 perfectly concise at just 6 words, front-loading the essential information with zero wasted words. Every element ('Get info', 'about a document', 'by id') earns its place in this minimal formulation.

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 lack of annotations, 0% schema description coverage, and no output schema, the description is insufficiently complete. A read operation tool needs more context about what information is returned, error handling, and usage constraints to be fully usable by an agent.

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 has 0% description coverage, so the description must compensate. It mentions 'by id' which clarifies the purpose of the single parameter, but doesn't explain what format the ID should be (numeric, UUID, etc.), where to obtain it, or validation rules. This provides minimal value beyond the bare schema.

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 action ('Get info') and target resource ('about a document by id'), making the purpose immediately understandable. However, it doesn't differentiate this tool from its sibling 'documents_list' (which presumably lists multiple documents rather than retrieving a single one), preventing a perfect score.

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 no guidance on when to use this tool versus alternatives like 'documents_list' or 'collections_list'. It doesn't specify prerequisites, error conditions, or typical use cases, leaving the agent with minimal context for tool selection.

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