rotate_pdf

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

No annotations, but the description explains the transformation (PDF rotation) and return value, covering key behavioral aspects.

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?

Front-loaded purpose, followed by concise Arg list. Every sentence adds value with no extraneous text.

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?

Fully covers all input parameters and action; output schema exists, so return value is implicitly clear. 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?

Description adds meaning to all three parameters: pdf_base64 as base64-encoded file, angle as specific values (90,180,270), and pages with default 'all'. This compensates for the 0% schema coverage.

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?

Clearly states 'Rotate pages in a PDF' with specific verb and resource, and is distinct from sibling tools like merge_pdfs or extract_text_from_pdf.

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?

Provides no explicit guidance on when to use this tool vs alternatives, but the description implies it's for rotating PDF pages.

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