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

With no annotations at all, the description carries the full behavioral burden and does disclose the two things an agent most needs: the operation is irreversible ('Permanently') and it destroys an enumerated set of child resources. It stops short of stating authorization requirements, confirmation needs, or what happens to in-flight state on failure.

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?

One sentence, front-loaded with the destructive verb and resource, then the blast radius. Nothing is redundant or padded.

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 annotations and no output schema, the description covers the essential facts: irreversibility and what is destroyed. It is slightly thin on authorization and failure behavior, which an agent might need before invoking a permanent delete.

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 100% and the single projectId parameter is already documented as 'Database ID of the project to delete'. The description adds no format, range, or lookup guidance beyond that, so the schema does all the work and 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?

The description pairs a specific verb ('Permanently delete') with a precise resource ('an entire project workspace') and enumerates the cascading scope (collections, mock endpoints, rules, request logs). That scope statement makes it distinguishable from the narrower delete_mock and delete_state siblings without needing to open any schema.

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?

Usage is only implied by the word 'Permanently' and the breadth of the cascade; there is no explicit when-to-use vs when-not guidance, no mention of the alternative of removing individual resources, and no stated preconditions such as required ownership or permissions.

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