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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description adds the auth requirement (projects:write scope), which is genuinely useful context, but it says nothing about whether deletion cascades to child records (tasks, milestones, budgets) or is reversible.

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, front-loaded with the action and identifier, no filler. Every phrase carries 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?

For a destructive single-parameter delete, annotations and schema carry most of the load and the scope note covers the gap. The unresolved question of cascading deletion on a parent project is the one omission that would materially affect agent behavior, but the tool is otherwise callable as documented.

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?

Single parameter with 100% schema description coverage, so the schema already documents the UUID id. The description's "by ID" restates what the schema carries without adding format or resolution guidance. Baseline 3 is appropriate.

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 (Delete) and resource (project) plus the lookup key (by ID), which is clearer than the bare title. It does not differentiate from the many project-scoped delete siblings such as delete_project_task or delete_project_asset, so an agent could conflate the parent-entity delete with the sub-resource deletes.

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 gives no when-to-use guidance, no prerequisites beyond scope, and no pointer to alternatives. With ~150 delete siblings in the namespace, an agent gets no help deciding when deleting a whole project is the right call versus deleting its child records.

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