laddro.resumes.render

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

The description adds the behavioral detail 'Costs 1 API credit' beyond the annotations (which include readOnlyHint=true but no credit cost info). It does not contradict annotations. It could further disclose error handling or output format, but given annotations cover safety, this is satisfactory.

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 two sentences, concise and front-loaded. The first sentence states the core purpose, and the second adds a critical cost detail. No superfluous words.

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 9 parameters (all described in schema), an output schema, and annotations, the description is fairly complete. It could explicitly mention that the output is a PDF binary or provide error context, but that is partially covered by the tool name and schema. The added credit cost improves completeness.

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 coverage is 100% (all parameters have descriptions), so the baseline is 3. The description only reiterates 'specific template and styling settings' in a general sense, adding no per-parameter semantics beyond what the schema already provides.

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 ('Render a resume as PDF') and specifies key attributes ('with specific template and styling settings', 'Costs 1 API credit'). It effectively distinguishes this tool from siblings like laddro.resumes.export (which likely exports in other formats) and laddro.resumes.tailor (content tailoring).

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 implies usage for generating a PDF with custom styling, but it does not explicitly state when to use this tool over alternatives (e.g., laddro.resumes.export). No exclusions or comparative guidance is provided; the context is only implied.

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