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

Beyond the annotations, it discloses that links are publicly readable by anyone who has them, changed settings produce a new link, hosted calls consume request quota, and private telemetry is recorded. It also clarifies the no-storage and no-subscription behavior, which is important for a non-read-only, non-idempotent tool.

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 front-loaded with the core purpose and then uses short sentences to cover usage constraints, privacy, link behavior, and quota implications. Every sentence adds useful information without restating the tool name or title.

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, rich annotations, and 83% schema description coverage, the description is complete enough for an agent to call the tool correctly. It fills the key behavioral gaps around privacy, link sharing, quota, and telemetry.

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 high at 83%, so the schema already documents most parameter semantics. The description reinforces the five-interest limit, 1–50-mile radius, and per-interest area override, but those details are largely present in the schema rather than adding substantial new meaning.

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 states a specific verb and resource: return Google, Apple, and Outlook subscription links plus an exact live preview. It also clarifies that no stored account or calendar is created and no calendar app is subscribed, which meaningfully distinguishes it from create_calendar_draft.

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?

It gives useful context such as no VenuNite sign-in and no stored account, implying when this tool is appropriate, but it never explicitly says when to use it instead of siblings like create_calendar_draft or search_events. The usage boundary is inferable rather than stated.

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