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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so 'This is a destructive project operation' merely restates structured data. The description omits genuinely useful behavior: whether deletion is permanent/irreversible, whether it cascades to variants, assets, screenshots, or layouts, and whether confirmation or special permissions are required.

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?

Very short and front-loaded, but the second sentence is pure redundancy against the annotations, so half the text earns no place. Efficient in size, weak in density of useful information.

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 explained, but for an irreversible destructive operation with cascading side effects and an undocumented id parameter, the description says nothing an agent needs before invoking it. It is under-specified for the risk level of the tool.

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?

One required parameter with 0% schema description coverage; the schema gives only type/format/pattern, not what a project is or where to obtain the id. 'The specified project' adds nothing beyond the parameter name, and does not point the agent to list_projects or get_project.

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 ('Deletes the specified project'), which is unambiguous on its own. It does not distinguish itself from similar destructive siblings such as delete_assets, delete_variant, or delete_asset_folder, so an agent gets no help disambiguating scope.

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?

No guidance on when to use this versus the other delete tools, no prerequisites (where the projectId comes from, e.g. list_projects or get_project), and no warning about what must be done before deleting. Only implied usage from the name.

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