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

No annotations are supplied, so the description carries the full behavioral burden for a destructive operation. It does not say whether deletion is irreversible, what happens to the underlying website content or subscription, whether the website must be unpublished first, or what the response contains. 'Delete' alone conveys no side-effect or permission information.

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?

A single short sentence with no filler and the verb front-loaded. Its terseness is the problem addressed under completeness, not a structural flaw.

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, annotation-less tool with no output schema and several near-identical deletion siblings, the description is too thin. It leaves the agent guessing about irreversibility, side effects and correct tool selection among website_delete, website_property_delete and subscription_remove_agent_website.

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?

There is one parameter and schema coverage is 100%, with the schema already explaining that agentId identifies the owning agent. The description adds no meaning beyond that, so the baseline of 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 verb and resource ('Delete an agent website'), but leaves the core ambiguity unresolved: whether it deletes the website entity itself or only the agent-to-website association. The presence of both 'website_delete' and 'subscription_remove_agent_website' as siblings makes that distinction critical, and the description does nothing to separate itself from them.

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 when-to-use guidance and no named alternative. An agent cannot tell from the description whether this is the right tool for detaching a website from an agent versus deleting the site outright, which is exactly the decision the sibling list implies it must make.

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