read-pdf-contentExtract the textual content of a PDF file, page by page.
| Name | Required | Description | Default |
|---|---|---|---|
| file | Yes | Publicly reachable URL of the PDF file to read. | |
| async | No | Run the action asynchronously and return a job id instead of the result. Poll "check-job-status" or set "webhook_url" to receive a callback. | |
| webhook_url | No | Callback URL invoked when an async job finishes. Only used when "async" is true. |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint=true, which matches read behavior. Description adds 'page by page' but lacks details on return format or handling of image-based PDFs. Some value beyond annotations but limited.
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?
Single sentence, front-loaded with core purpose. No superfluous 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?
No output schema and description does not indicate return structure (e.g., array of page texts). Incomplete for an agent to know what to expect.
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% with descriptions for all 3 parameters. Description adds no additional meaning beyond schema; 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 it extracts textual content page by page from a PDF file. Distinguishes from siblings like read-pdf-content-with-ocr and search-pdf-content.
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?
No guidance on when to use this tool vs alternatives (e.g., OCR for scanned PDFs). No context on prerequisites or when not to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
