remove_initiate_login_uri

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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered. The description adds genuinely new context beyond the annotations — the OAuth token requirement — and confirms the destructive semantics ('This deletes the URI'), though it says nothing about what happens on repeated calls or when no URI is set.

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?

Four short sentences, front-loaded with the purpose before alternatives and the auth note. The trailing 'This deletes the URI' is largely redundant with destructiveHint=true, so it does not earn its place as strongly as the rest.

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 single-parameter, no-output-schema tool, the description covers purpose, alternatives for the set and read cases, and the authentication requirement. Return values need not be explained, and nothing an agent needs to invoke this correctly appears missing.

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 a single parameter with 100% schema description coverage (including the env_<id> format pattern), so the schema carries the parameter semantics. The description adds no format or constraint detail beyond naming the environment, which is the expected baseline.

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?

The first sentence states a specific verb and resource ('Clear the initiate-login URI for an environment'), which is unambiguous and separable from sibling operations like remove_redirect_uri or set_initiate_login_uri. An agent can identify the target resource and the mutation without opening the 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?

It explicitly routes to two named alternatives with their conditions: set_initiate_login_uri for setting a new value and list_redirect_uris for reading the current one. It also states the authentication prerequisite ('Requires the caller OAuth token'), leaving little to inference.

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