getSpecFiles

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

Annotations already indicate read-only, idempotent, and non-destructive behavior, so the description adds no new behavioral traits. It does not disclose additional context like rate limits, authentication needs, or what 'all the files' entails (e.g., format, pagination). No contradiction with annotations exists.

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 a single, efficient sentence with no wasted words. It is front-loaded with the core action and resource, making it easy to parse quickly.

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 simple single parameter with full schema coverage and annotations covering safety, the description is minimally adequate. However, without an output schema, it fails to explain return values (e.g., list structure, file details), leaving a gap in completeness for a tool that retrieves multiple items.

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 input schema has 100% description coverage, with 'specId' clearly documented. The description adds no meaning beyond this, such as explaining where to find the specId or its format. The baseline score of 3 is appropriate as the schema carries the full burden.

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 verb ('Gets') and resource ('all the files in an API specification'), making the purpose explicit. However, it does not differentiate from sibling tools like 'getSpecFile' (singular) or 'getAllSpecs', which could cause confusion about scope or specificity.

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 such as 'getSpecFile' for a single file or 'getAllSpecs' for listing specifications themselves. It lacks context about prerequisites, exclusions, or typical scenarios for invocation.

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