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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, so the safety profile is covered. The description adds nothing beyond that — no mention of pagination, result ordering, result size, or whether it returns all projects or a filtered subset, which matters for a listing 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?

A single short sentence with no filler or redundancy, and the resource is front-loaded after the verb. Its brevity is efficient, though the shortness reflects under-specification rather than disciplined editing.

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 one required, undocumented parameter, no output schema, and no parameter descriptions, the description should carry more weight than it does. Annotations cover safety and idempotency, so the gap is not fatal, but an agent gains little understanding of what a 'profile project' record looks like or how to use the returned list.

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 0% for the single required parameter workspace_id, so the burden falls on the description. The phrase 'in the workspace' hints that the parameter scopes results to a workspace, but it never states what a workspace_id is, how to obtain it, or whether the list is filtered by it — the schema remains effectively undocumented.

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 gives a verb and resource ('List profile projects'), but 'profile projects' is ambiguous — it is unclear whether these are RudderStack Profiles projects, audience profiles, or profile-related resources. It does not distinguish the tool from siblings like get_profile_details or get_profile_artifacts, which an agent would need to choose between.

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, no statement of prerequisites, and no reference to alternatives such as get_profile_details for a single profile. The agent must infer from the name alone whether this is the right entry point.

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