Convert PDF to Other Format

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=true. The description adds behavioral context: conversion to multiple formats, URL requirement, and optional page range. No contradictions; useful extra detail.

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?

Two sentences, front-loaded with main purpose. Every sentence provides essential information: formats, page range, source requirement. No wasted 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?

With 3 parameters fully described in schema, annotations present, and existence of output schema, the description covers all necessary context: what it does, input requirements, and optional settings. No 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?

Schema description coverage is 100%, so the schema already documents parameters well. The description adds minimal extra meaning beyond listing target formats and noting page range optionality. Baseline 3 is appropriate.

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?

Description clearly states 'Convert PDF to Word (DOCX), Excel (XLSX), PowerPoint (PPTX), plain text (TXT), or images (JPG/PNG per page)'. It specifies the verb (Convert), resource (PDF), and lists target formats, distinguishing it from siblings like document.convert.to_pdf and other PDF tools.

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?

Description mentions 'Optional page range selection' and 'Provide PDF as URL', giving context for usage. It doesn't explicitly state when not to use or provide alternatives, but the sibling names make the differentiation natural. Clear enough for an agent.

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