Publish timeline

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

The description discloses that publishing exposes the timeline, explains the access difference between 'private' and 'link', and states the return value (view and offline-download URLs). Since annotations only cover read-only/destructive hints, this adds useful behavioral context without contradicting them.

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 focused sentences deliver the core action, visibility semantics, and return value with no wasted words. The description is front-loaded with the primary purpose and immediately gives the agent actionable details.

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 simple two-parameter publish action, the description covers the operation, access behavior, and return URLs, even though there is no output schema. It could mention re-publishing behavior or prerequisites, but the essential information for correct invocation is present.

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?

The description adds real meaning to the visibility parameter by explaining who can access the timeline in each mode, compensating for the 0% schema description coverage. However, timeline_id, the required parameter, is not described beyond its schema name, so compensation is only partial.

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 uses a specific verb, 'Publish', with a clear resource, 'the built timeline', and adds meaningful scope by defining visibility options and return URLs. This clearly distinguishes it from sibling tools like build_timeline and get_timeline.

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 phrase 'built timeline' implies this is the final step after build_timeline, and the visibility options give practical usage context. However, the description does not explicitly state when not to use it or mention alternatives, leaving some inference required.

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