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

Annotations declare destructiveHint=true and idempotentHint=true, and the description begins with 'Requires member:write,' which adds the needed authorization context beyond annotations. It does not clarify the behavior when the item does not exist (e.g., error vs. success), but the idempotentHint already implies safe repetition, so the description adds sufficient value.

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 description is very short, two sentences, with the critical authorization requirement front-loaded. Every word is useful, and there is no redundant filler. This is an excellent example of concise and well-structured writing.

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?

Given the tool's moderate complexity (two required params) and the presence of an output schema and annotations, the description is largely sufficient for a safe call. However, it lacks any context on return values or error handling (e.g., what happens if the item doesn't exist), which could be important for an agent to handle edge cases. Thus, it is adequate but not complete.

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%, so the description must explain the parameters, but it does not. The 'type' enum is visible in the schema, and the 'id' is a string, so an agent can infer what is needed, but the description offers no additional clarity on how type and id combine to identify a saved item. Given zero coverage, this is a gap, but the schema's enum provides some context, so a baseline 3.

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 description states a clear verb ('remove') and resource ('one saved guide item') and specifies the target ('from the connected member account'), which is sufficiently clear. It does not explicitly contrast with siblings like save_guide_item, but the inverse relationship is obvious, so it earns a 4 rather than a 5.

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?

The description provides no explicit guidance on when to use this tool versus alternatives. While it is the obvious inverse of save_guide_item, there is no mention of prerequisites like 'only if the item is saved' or any alternatives for managing guide state, leaving the agent to infer usage.

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