createMilestoneTimelineSlide

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

The description mentions 'create or update,' hinting at mutation behavior, but discloses no other behavioral traits such as needed permissions, side effects (e.g., overwriting existing slides), rate limits, or response format. With no annotations, the description carries the full burden but provides minimal 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?

The description is extremely concise (five words) but lacks substantive information. While no fluff exists, the brevity undermines usefulness; it should front-load key details like the role of milestones and the update capability.

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 no annotations, no output schema, and only 33% schema description coverage, the description fails to provide a complete picture. It doesn't explain what a milestone timeline slide is, return value expectations, or how the update logic works beyond the _index hint in the schema.

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 does not explain any parameters meaningfully; it repeats the schema structure only implicitly. Schema coverage is 33% (only _index has a description), and the tool description adds no value beyond the schema, failing to compensate for missing parameter descriptions.

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 'Create or update a milestone timeline,' which clearly identifies the action (create/update) and the resource (milestone timeline). The name reinforces this. However, it doesn't specify what constitutes a milestone timeline or how it differs from other slide types among the many siblings.

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?

No guidance is provided on when to use this tool versus the many other slide creation tools in the sibling list. There is no indication of prerequisites, context, or exclusions, leaving the agent without decision support.

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