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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuine behavioral context beyond that: an idempotency/retry protocol, a canonicality note about trusting actual_tool_output, and a mandatory fresh-confirmation requirement — useful for a destructive mutation.

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 and the parenthetical is efficient, but the body is padded with generic boilerplate sections (Canonicality, Idempotency, Confirmation boundary) and a dangling reference to prerequisites 'stated above'. Some sentences do not earn their place for this specific tool.

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?

No output schema exists, and the description only gesturally points to 'returned actual_tool_output and context_engineering' rather than describing what removal yields. It does cover auth prerequisite, retry behavior and confirmation, which is adequate for a destructive single-action tool but leaves the post-call state under-explained.

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 0%, but the only parameter is the infrastructure-level _corply_context object (id/receipt), not a domain-specific input. The description adds no explicit parameter meaning, though it alludes to a 'tool-specific retry key' that might relate to the receipt. Baseline 3 is fair given the parameter is a system context wrapper.

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+resource ('Remove a chosen domain from the company's checkout before it is paid') and clarifies scope with the parenthetical that the founder decided not to register it. This distinguishes it reasonably from siblings like choose_company_domain and start_company_domain_checkout, though it never names 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?

Provides a conditional context ('before it is paid') and a prerequisite ('authenticated active company access'), plus a confirmation boundary. But it names no alternative tool and the prerequisite is self-referential ('every prerequisite stated above' — which does not exist here), leaving the when-to-use vs siblings implied rather than explicit.

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