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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds little beyond that — the endpoint reference (GET /projects/{id}) is a restatement, and there's no mention of error behavior for missing ids or what a project record contains, though the latter is partially excused by the lack of an output schema.

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?

Two short sentences, with the actual purpose front-loaded. The API endpoint line is low-value filler but not harmful.

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?

This is a simple one-parameter read tool with full schema coverage and a readOnlyHint, so heavy description isn't required. Still, nothing is said about the returned project or failure modes, leaving the definition minimally adequate rather than complete.

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 coverage is 100% for the single required parameter, so the baseline of 3 applies. The description contributes nothing beyond the schema's 'The project id.' and doesn't clarify whether the id is numeric or string despite the schema allowing both.

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 ('Get one project by id'), which naturally distinguishes it from the sibling list_projects. It doesn't explicitly name the sibling, but the singular/plural distinction 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?

Usage is implied: fetch a single project when you have its id. There's no explicit guidance on when to prefer this over craftboxx_list_projects or what happens if the id is unknown, but the condition for use is reasonably inferable.

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