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

The description states that brandProfile 'replaces both lists entirely' and warns to 'pass every domain and name the project should keep', which implies omitted entries are removed. That is a destructive update, but the annotations declare destructiveHint=false. This is a contradiction. The description also restates idempotency from the annotations via 'Safe to retry'.

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, front-loaded sentences with no filler. The first sentence states capabilities, the second explains the critical replacement behavior, and the third adds retry safety.

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 not be described. The description covers the key mutation semantics and idempotency, but it omits any mention of required organizationId/projectId and does not address permissions or auth requirements. Given the tool's complexity, it is mostly complete but has minor gaps.

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 only 25%. The description compensates for brandProfile by explaining full replacement semantics and clarifies that name and brandProfile are optional ('or both'). However, the required organizationId and projectId parameters receive no explanation beyond their self-evident names.

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 gives specific verbs and resources: rename a project and replace the website domains and brand names it is monitored for. It clearly distinguishes update_project from create_project or get_project by focusing on modification. However, it does not explicitly name any sibling tool or clarify when to use it instead of those 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?

The description implies usage by listing what can be changed, but it offers no explicit when-to-use guidance, prerequisites, or alternatives. It does not tell the agent when not to use this tool versus create_project, update_organization, or rename_cluster.

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