A3.5/5.0

Behavior3/5

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

Annotations already establish that this is a safe read-only operation. The description adds useful behavioral context about alias normalization (e.g., 'your-tenant-int' → 'your-tenant-storefront-int'), but it does not disclose pagination behavior, authentication requirements, or result ordering.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose is front-loaded in the first sentence, and the alias rules follow efficiently. The second sentence is somewhat dense with examples but every part serves to clarify alias handling.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described. Annotations cover the safety profile, and the schema documents most parameters. The description covers purpose and alias behavior; only pagination and context_id usage are left entirely to structured fields, which is acceptable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 75%, so the baseline is 3. The description adds alias examples that augment the 'search' parameter, but it does not explain limit, teamId, or context_id, leaving those to the schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('List Vercel projects') and scopes it to 'the user/team'. It clearly distinguishes itself from sibling project-list tools by naming Vercel, though it does not explicitly contrast with tools like vercel_project_status.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied: list projects for a user/team with optional filtering. The description does not say when to use this versus alternatives such as vercel_project_status or vercel_deploys_latest, nor does it state exclusions or prerequisites.

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