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

No annotations are provided, so the description carries full burden. It only says 'detecting structure' without disclosing side effects, preconditions, or what the tool modifies. The agent cannot predict the tool's behavior confidently.

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 two sentences with no fluff and front-loaded. It is concise and well-structured, though the brevity sacrifices necessary detail.

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?

Given it has an output schema but no annotations, the description fails to explain what 'finalizes project setup' does, what structure detection involves, or what the output contains. The description is too minimal for an agent to understand the tool's complete contract.

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 schema has one required parameter (root_working_directory) with no description, and the tool description doesn't mention it at all. With 0% schema description coverage, the agent has zero semantic understanding of this parameter.

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 clear action ('Finalizes project setup') and resource, and distinguishes from sibling tools (init_project) by indicating this is a post-creation step. However, 'finalizes' is somewhat vague and doesn't specify what the finalization entails.

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?

Provides explicit when-to-use guidance: 'Call this tool immediately after creating any new project.' This makes the invocation context clear. It doesn't mention when not to use it or alternatives, but the instruction is specific enough.

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