Create Project Member

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

The description simply restates the action without disclosing behavioral traits such as sending an invitation, handling of existing users, or side effects. The annotations indicate it's a write operation with possible open-world effects, but the description doesn't elaborate.

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 a single, brief sentence with no unnecessary words. However, it is under-specified, which slightly reduces its value as a concise resource.

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?

Without an output schema and with only a minimal description, this tool is not fully documented. It doesn't explain return values, the relationship between email and username, or edge cases like duplicate memberships.

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 mention any parameters. The input schema covers role, email, and username, but project lacks a description. With 75% schema coverage, the description doesn't compensate for the missing project semantics.

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 clearly states the action (create) and resource (membership), and the title adds 'Project Member'. It distinguishes from sibling tools like membership_update and membership_delete, but it's minimal and doesn't explicitly note it's for a single membership vs bulk create.

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 membership_bulk_create or membership_update. The description lacks any context about prerequisites or alternatives.

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