conference_details

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

No annotations provided, so the description carries full burden. It states the tool fetches details and includes 'dates, deadlines, website, and categories' – implying a read operation. However, it does not disclose potential errors (e.g., invalid URL, network issues) or any side effects. This is adequate for a simple fetch operation but lacks depth.

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 the primary action. Every sentence adds value: first defines the core function, second clarifies the input source and output contents. 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?

The tool has an output schema, so the description does not need to detail return structure. It mentions included fields (dates, deadlines, website, categories). It does not discuss error handling or prerequisites beyond the URL source. Given the simplicity and presence of output schema, this is reasonably 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?

The schema has a single required 'url' parameter with no description (0% coverage). The description adds meaning by specifying that the URL comes from 'search_conferences' and is a WikiCFP page URL. This helps the agent understand the expected format and source beyond the bare schema.

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 fetches 'full details for a conference' from a specific WikiCFP URL. This distinguishes it from sibling tools like search_conferences (which returns URLs) and list_categories (which lists categories). The verb 'fetch' and resource 'details' are specific and unambiguous.

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 says 'The URL is the `url` field returned by search_conferences', which implies a workflow: first use search_conferences, then this tool. While it doesn't explicitly exclude other sources or describe when not to use it, the guidance is clear enough for an agent to understand the typical usage context.

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