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

Beyond the annotations, it discloses that the rename takes effect immediately, that Environments keep running, and that no human approval is involved. These are meaningful behavioral details for a mutation tool, though it does not discuss permissions or collision/error behavior.

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, front-loaded with the action and containing no wasted text. Each sentence adds a useful behavioral fact.

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 two-parameter mutation tool with annotations covering safety and no output schema, the description supplies the key operational context: immediate effect, environments unaffected, and no approval step. It is mostly complete, with minor gaps around permissions and error handling.

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 documents the new name ("to") and its uniqueness constraint, but the "project" parameter has no schema description. The description establishes that "project" is the target and "to" is the new name, but it adds little beyond that implicit mapping.

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: "Rename a Project." That is clear enough to distinguish it from project_create/project_remove and the other rename tools, though it does not explicitly name alternatives.

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?

It implies the operation is immediate and requires no human approval, which gives useful usage context. However, it does not explicitly say when to choose this over siblings such as service_rename or config_rename, nor does it state prerequisites or exclusions.

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