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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the useful fact that the slug returned is the dependency for other tools, but says nothing about return format, pagination, or result size. With annotations carrying the safety burden, this is adequate but not rich.

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 sentences, zero filler, and the actionable ordering instruction is front-loaded right after the purpose statement. Every clause earns its place.

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?

There is no output schema, so the description partially carries the return-value burden and does so minimally ('portals with their slug'). For a small, account-scoped list that is close to sufficient, though it omits any hint of whether all portals or a paginated subset are returned.

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% and the single optional 'fields' parameter is fully documented in the schema, so the baseline 3 applies. The description does not mention 'fields' or field-selection behavior, adding no meaning beyond the schema.

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 ('List the help center portals of this account') and identifies the key attribute returned ('with their slug'). This distinguishes it from delete_portal, update_portal, and add_new_portal_to_account in the sibling list without needing to open a 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?

Explicitly states the call ordering ('call this first') and gives the reason ('every other help center tool needs that slug'). An agent knows both when to use it and why it is a prerequisite for the help-center tool family.

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