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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=true and idempotentHint=false, so the write semantics and safe-retry profile are covered structurally. The description adds real value beyond that with the key-scope restriction on who may call it. It says nothing about what side effects occur on success, whether the creator gets owner rights, or how retries interact with request_id.

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?

Three short sentences, all load-bearing: the action first, the exclusion second, the authorization limit third. Zero filler and the core purpose is front-loaded.

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?

An output schema exists, so return values need no explanation, and the tool is a simple two-parameter create. The remaining gap is that the description never explains the workspace/account context a project is created under or the naming constraints, which matters for a creation call.

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?

With 50% schema description coverage, request_id is already fully documented in the schema and name carries only length bounds. The description adds no meaning to either parameter, notably nothing about name uniqueness or naming constraints within the workspace. Baseline 3 is appropriate since the schema does part of the work.

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?

States a specific verb and resource ("Create an engineering project") and immediately bounds it by excluding Design/Studio application projects, which lets an agent separate it from other create_* siblings. It stops short of naming the sibling that handles design projects, so the differentiation is by category rather than by tool.

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?

Gives an explicit when-not (not for Design/Studio application projects) and an eligibility precondition (project-restricted keys cannot create projects). It never points to an alternative tool to use instead, so an agent must infer the redirect from sibling names.

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