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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds substantive behavioral nuance: plan-limited runs_as behavior, credits_per_run_max cost caps, pending_first_audit activation after a successful audit, and recurring schedule/cost semantics.

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?

The purpose is front-loaded, but the remainder is a long, dense enumeration in a single paragraph. Much of the detail earns its place because there is no output schema, but the structure is burdensome and could be clearer with field grouping or bullets.

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?

With no output schema, the description carries the burden of explaining returned data and does so thoroughly: audit level, crawl settings, ownership, broken-link alerts, plan-limited runs_as, credit caps, and recurring-audit activation/cost semantics. It is complete enough for an agent to understand what this read tool returns and how plan constraints affect the values.

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 only one parameter, website_id, and schema description coverage is 100%, with the schema already explaining it comes from list_websites, run_audit, or add_website. The description adds no additional parameter-level meaning, so the high-coverage 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 specific verb, 'Read', and a specific resource, 'one website's stored audit settings', then enumerates the settings returned. It does not explicitly distinguish itself from update_website_settings or list_websites, so it is clear but lacks full sibling differentiation.

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?

There is no explicit when-to-use or when-not-to-use guidance, and the description does not route the agent between this tool, update_website_settings, or list_websites. 'Read one website's stored audit settings' implies inspection, but the usage context is left to inference.

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