read_openalex_paper

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

The description says 'Attempt to read' but the return value states reading is not supported, effectively indicating failure. This is misleading; the tool's true behavior (returning a failure message) is not disclosed upfront. No annotations exist to mitigate this.

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 concise with a clear structure: purpose, Args, Returns. No extraneous text. However, the content is misleading, which reduces effectiveness.

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 that an output schema exists, the description does not elaborate on the return value beyond 'str: Message indicating...'. The tool is non-functional as a reader, and the description does not clarify its limitations or offer alternatives, making it incomplete for practical use.

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?

The description adds meaning beyond the input schema: it explains paper_id as an OpenAlex paper ID and save_path as a directory for saving, including a default. Since schema coverage is 0%, this is valuable clarification.

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 states 'Attempt to read and extract text content from an OpenAlex paper,' but the return message indicates 'direct paper reading is not supported natively,' creating confusion about the tool's actual purpose. It is not a tautology, but it is vague and contradictory.

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 versus sibling read tools (e.g., read_arxiv_paper). No when-not-to-use or alternative suggestions are provided. The misleading implication that it can read papers makes the usage context unclear.

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