read_hal_paper

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

No annotations are provided, so the description carries full burden. It mentions extraction and saving to a directory, but lacks critical behavioral details: whether it downloads the paper first, what format the extracted text is in, error handling, rate limits, authentication requirements, or whether it modifies existing files. For a tool with no annotations, this leaves significant gaps in understanding its behavior.

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 well-structured with a clear purpose statement followed by Args and Returns sections. It's appropriately sized with no redundant information. However, the 'Returns' section could be integrated more smoothly, and the description could be slightly more front-loaded with key behavioral information.

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?

The tool has an output schema (returns str), so the description doesn't need to explain return values. However, with no annotations, 2 parameters (one with 0% schema coverage), and behavioral complexity (involving both reading and potentially downloading), the description should provide more context about how the tool works, error conditions, and typical use cases to be truly complete.

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 0%, so the schema provides no parameter descriptions. The description adds basic semantics: 'paper_id: HAL paper identifier' and 'save_path: Directory where the PDF is/will be saved (default: './downloads').' This clarifies what each parameter represents, but doesn't provide format details (e.g., HAL ID format, path requirements) or explain the relationship between downloading and reading. Given the coverage gap, this is minimally adequate.

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 tool's purpose: 'Read and extract text content from a HAL paper.' It specifies the verb ('read and extract'), resource ('HAL paper'), and outcome ('text content'). However, it doesn't explicitly differentiate from sibling tools like 'read_arxiv_paper' or 'download_hal', which have similar naming patterns but potentially different functions.

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 provides no guidance on when to use this tool versus alternatives. With many sibling tools (e.g., 'download_hal', 'search_hal', other 'read_*' tools), there's no indication of when this specific HAL paper reading tool is appropriate, what prerequisites exist, or when other tools might be better suited.

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