Create a GifOS meeting

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

With no annotations, the description carries the full behavioral burden and it does useful work: it discloses that no one joins on creation, that start_time is stored verbatim and never triggers scheduling, and that the output is a shareable link. It does not mention auth/permission requirements or limits, but the non-obvious semantics are covered well.

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?

Three short sentences, front-loaded with the core action and then the sequencing caveat and the scheduling caveat. Every sentence carries distinct information; nothing repeats the title or schema.

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?

For a two-parameter creation tool with no annotations and no output schema, the description covers what is produced (a link), how it is consumed, and the next tool in the flow. There is no meaningful gap an agent would need filled to invoke it correctly.

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%, so baseline is 3, but the description goes beyond the schema's terse "Informational only" for start_time by spelling out the consequence: it is stored as given for the agent's own scheduling and the server never schedules. That added implication is real value over the field text.

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 ("Creates a new GifOS meeting link") and immediately clarifies the non-obvious distinction from a meeting actually running ("Nothing joins yet"), which separates it from siblings like start_meeting and join_meeting. An agent can pick this tool without reading any other schema.

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 explicitly prescribes the workflow: create the link, share it (e.g. in a calendar invite the user approves), then call start_meeting at meeting time. It also states what this tool does NOT do (schedule anything), which is a clear exclusion rather than implied usage.

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