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

Annotations only provide destructiveHint=true, which is a coarse safety signal. The description adds that this is a POST creation endpoint and mentions optional fields, but it does not explain authentication requirements, whether duplicate project names are allowed, what happens to omitted fields, or any side effects.

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 compact single sentence plus a backend endpoint note. The main purpose is front-loaded, and there is little wasted text, though the POST endpoint is of marginal value to an agent.

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 no output schema, the description should explain what the tool returns or confirm success behavior, but it does not. It also omits required fields, permission expectations, and any error or side-effect context for a creation tool with eight parameters.

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 63%, so the schema partially documents parameters. The description names three optional fields (task_rate, budget, due_date) and implies name and client_id are required, but it omits color, public_notes, and private_notes and adds no format details beyond the schema.

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 a specific verb and resource: create a project. It adds key optional attributes (hourly task rate, budget, due date) and the underlying POST endpoint. It does not explicitly differentiate from sibling create tools, but the resource is unambiguous.

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 guidance on when to use this tool versus alternatives such as list_projects, create_task, or create_client. The description only states what the tool does, leaving all usage context to inference.

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