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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions that the tool can save to custom folders and create them if needed, which adds some context. However, it fails to disclose critical behavioral traits such as whether this is a read-only or mutation operation (implied mutation from 'Generate'), potential side effects (e.g., file creation), error handling, or performance considerations like rate limits. The description is too sparse for a tool that creates files.

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 appropriately concise with two sentences that efficiently convey the core functionality and a key feature (folder saving). It is front-loaded with the main purpose. There is no wasted verbiage, though it could be slightly more structured by separating usage notes, but this is minor.

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 tool's complexity (3 parameters with nested objects, no output schema, and no annotations), the description is incomplete. It lacks details on output (e.g., what the PDF response looks like, error formats), behavioral expectations, and integration with sibling tools. For a tool that generates files and interacts with a directory structure, more context is needed to guide the agent effectively.

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 schema fully documents the three parameters (resumeData, filename, folderPath). The description adds minimal value beyond the schema: it implies that resumeData is used for PDF generation and mentions folderPath functionality ('saves to custom folders within the generated-resumes directory'). However, it doesn't provide additional semantic context, such as examples of resumeData structure or usage tips, resulting in a baseline score of 3.

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 tool's purpose: 'Generate a resume PDF using the LaTeX Resume API' with the specific action 'Provide resume data and get a professionally formatted PDF.' It distinguishes from siblings like 'create_resume_template' by focusing on PDF generation rather than template creation. However, it doesn't explicitly differentiate from all siblings (e.g., 'create_folder' or 'list_folders'), keeping it from 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 minimal usage guidance: it mentions saving to custom folders but lacks explicit when-to-use instructions, prerequisites, or alternatives. For instance, it doesn't clarify when to use this tool versus 'create_resume_template' or how it relates to folder management tools like 'create_folder' and 'list_folders'. This leaves the agent with insufficient context for optimal tool selection.

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