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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds useful scope context (your projects plus those you were granted access to, with presentations in order), but the trailing sentence about blocks leading to slides of other presentations is confusing and does not clearly describe this tool's behavior.

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 domain definition is front-loaded, which is reasonable, but the last sentence is opaque and arguably off-topic for a list operation, diluting otherwise compact prose.

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?

With an output schema present and rich annotations, the description is not required to explain return values or safety, and it does supply the access scope. However, it omits any routing information among the many sibling tools and ends with a sentence that confuses rather than completes the picture.

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 tool takes zero parameters, so there is nothing for the description to disambiguate. Baseline 4 applies for a parameterless tool.

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 defines what a project is ('presentations that belong together') and describes the scope of what is returned, but never states the action verb directly — the listing behavior is carried entirely by the name/title. It also does not distinguish this tool from siblings like get_project or list_presentations, so the agent must infer the distinction from naming alone.

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?

There is no when-to-use guidance and no alternative named; nothing tells the agent to prefer get_project for a single project or list_presentations for presentations. The access-scope sentence implies coverage but not when this call is appropriate.

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