events_fetch_page

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

No annotations are provided, so the description must carry full behavioral transparency burden. It states it 'Fetches the URL linked in the event name cell' and returns details, but it does not disclose whether it follows redirects, handles timeouts, or requires authentication. This is adequate but not comprehensive.

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 three sentences: purpose, usage context, and parameter details. No redundancy, well-structured, and front-loaded with the most important 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 description covers purpose, usage guidelines, and parameter semantics sufficiently. Given that an output schema likely defines return values, this is not a gap. However, it lacks mention of prerequisites (e.g., the event must exist in the sheet) or potential errors, making it slightly incomplete.

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?

With 0% schema description coverage, the description fully compensates by explaining event_name as 'Full or partial event name (case-insensitive)' and year as 'Calendar year — '2025' or '2026' (default: '2026')', adding crucial semantics missing from the 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?

The description clearly states 'Fetch and read the linked event website for a specific event', specifying the verb ('Fetch and read') and resource ('linked event website'). It distinguishes itself from sibling tools like events_detail or events_search by focusing on external website content beyond the sheet.

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 explicitly says 'Use this when you need details not in the sheet — venue, agenda, speakers, registration info, pricing', providing clear usage context. However, it does not mention when not to use it or explicitly name alternative tools, missing some depth.

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