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

With no annotations, the description carries the full burden and does meaningful work: it discloses the destructive blast radius (all projects and vaults) and the auth requirement (X-API-Key, with a fallback). It omits whether the action is reversible or how the confirm flag interacts with execution, which is the main residual gap for a destructive tool.

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 tight sentences with the destructive purpose front-loaded before the authentication detail. Every sentence carries information about what the tool does or how to authenticate.

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, no-output, no-annotation tool, the definition covers the critical facts: cascade scope and authentication. It would be fully complete if it stated irreversibility or that confirm must be true to proceed, but the schema enum already enforces the latter.

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 coverage is 100%, so both api_key and confirm are already documented in the schema, including the header fallback and the confirm-to-proceed semantics. The description largely restates the api_key rationale, 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 and resource ('Deletes the team account') and immediately qualifies scope with the cascade ('plus all projects and vaults'). This scope wording distinguishes it from siblings like delete_project and delete-code-vault, which act on single resources.

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 implied by the account-wide cascade, and it usefully explains the header-vs-argument auth path. However, it never states when to prefer this over the narrower delete_project / delete-code-vault siblings or any preconditions beyond authentication.

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