get_updated_events

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

No annotations exist, so description bears full burden. It mentions returned fields (title, times, location, etc.) but lacks details on inclusion/exclusion of updated_after, pagination, or rate limits. The label color mapping adds some context.

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 plus a compact list of label colors. No redundant information. Could potentially separate the color list, but it remains concise.

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, so missing return structure. No mention of pagination, error handling, or behavior under edge cases. Adequate for basic usage but not fully comprehensive for a tool with 3 parameters and many siblings.

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 covers 100% of parameters. Description adds value by explaining how to convert dates to timestamps for 'updated_after', and restates the purpose for 'calendar_id'. The label color mapping is a bonus beyond 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 verb 'Get', resource 'events from a specific TimeTree calendar', and filter 'updated after a specified time'. It distinguishes from siblings like 'get_events' (which likely lacks time filter) and other mutation tools.

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?

States 'Useful for finding recently modified events', providing a usage context. However, it does not explicitly compare to alternatives like 'get_events' or specify when not to use this tool.

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