Rename project

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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description adds 'MUTATING' and notes that the 31-character limit comes from app validation, which is modest additional context, but it still does not explain permissions, reversibility, or side effects beyond what the annotations imply.

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 very short and front-loads the core action. However, the 'Max 31 chars (app validation)' detail overlaps with the schema's maxLength and name description, making it slightly redundant rather than purely additive.

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?

For a simple two-parameter rename operation with full schema coverage and annotations covering safety semantics, the description is largely complete. It could be richer about behavior around invalid names or the response, but no output schema exists and annotations cover the key safety profile.

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 100%, so both parameters are already documented in the input schema, including the 31-character maximum for 'name' and the source of 'id' from project_list. The description does not add meaning beyond what the schema provides.

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 uses a specific verb and resource ('Rename a project') and identifies the underlying operation ('renameFirmware'). It clearly distinguishes renaming from creation, deletion, or loading, but does not explicitly contrast itself with all sibling project tools.

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?

The description states that the operation is mutating and enforces a 31-character limit, but gives no guidance on when to use this tool versus alternatives such as project_save, project_create, or project_delete. An agent must infer the usage context.

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