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 structurally. The description adds the required scope ('projects:write'), which is genuine value beyond the annotations, but it says nothing about cascade effects on child records, reversibility, or preconditions such as project state, which matter for a destructive project-level delete.

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, front-loaded sentences: the action first, the auth requirement second. Nothing is padded or redundant.

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 one-parameter destructive tool with no output schema, the description covers action and authorization, which is the minimum viable set. It leaves the operationally important question of downstream impact on project sub-resources unanswered, which is a real gap for a delete at the project level.

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?

Only one parameter, and schema description coverage is 100% ('Project ID' with uuid format). The description adds no format or lookup guidance beyond the schema, so the baseline 3 applies.

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 ('a project') with the identifier form ('by ID'), which cleanly separates it from the many delete_project_* siblings that remove sub-resources rather than the project itself. It stops short of explicitly naming that distinction, so it doesn't quite reach 5.

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 an implied usage context (delete by ID) and a prerequisite scope, but offers no when-to-use guidance, no exclusions, and no pointer to alternatives such as a soft-delete or the project-archiving path. Usage is only lightly implied.

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