Extract Meeting from ICS

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

Annotations already declare readOnlyHint=true, and the description adds value by disclosing that the tool returns null when no ICS block is found and supports RFC 5545 line folding and specific VEVENT properties. No contradiction.

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 (two sentences), front-loaded with the core action, and every sentence adds meaningful information. No fluff.

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 the presence of an output schema (inferred from description), the description adequately covers input and behavior. It mentions supported properties and return format for missing ICS. Minor gap: does not mention possible errors or limitations (e.g., unsupported properties).

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 coverage is 100% with descriptions for all parameters. The tool description does not add significant meaning beyond what the schema provides; it focuses on the tool's overall behavior rather than parameter details.

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: parse an ICS file or inline VCALENDAR from an email and return structured meeting details. It specifies the return value when no ICS is found, distinguishing it clearly from sibling extraction tools like extract_action_items.

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 implies usage context by naming the input (email with ICS), but does not explicitly provide when-to-use or when-not-to-use guidance relative to sibling tools (e.g., extract_action_items). No exclusions or alternatives are mentioned.

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