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

With no annotations provided, the description carries the full burden of behavioral disclosure. It says 'without mutation,' which is confusing given that 'dismiss' typically implies a state change; this contradiction is not clarified. It does not disclose side effects, required permissions, reversibility, or what happens to the recommendation after dismissal. This is a significant gap for a tool that likely mutates some state.

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 a single sentence, which is concise and front-loads the action. However, it lacks structure (no separate sections) and does not include critical details like parameter guidance or workflow context. While brevity is appreciated, the content is too sparse to be effective.

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 role in an optimization workflow alongside siblings like optimization_prepare_action and optimization_list_decisions, the description is woefully incomplete. It does not explain how this tool fits into the workflow, where decision_ref comes from, or what happens after dismissal. There is no output schema, so the agent has no expectation of the return value. This is inadequate for an agent to invoke it correctly.

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?

The schema has one required parameter, decision_ref, with a pattern and length constraints but no description. The tool description does not mention this parameter at all, providing no additional meaning about its format, purpose, or how to obtain a valid value. Since schema description coverage is 0%, the description should compensate, but it does not.

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 specific action (dismiss) on a specific resource (recommendation) with qualifiers ('open', 'tenant-owned'). This is a clear verb+resource pairing that differentiates from siblings like optimization_evaluate or optimization_list_decisions, though it does not explicitly name them. The purpose is reasonably clear, but the phrasing 'without mutation' introduces slight ambiguity that could confuse the agent about the action's actual effect.

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 guidance on when to use this tool versus alternatives such as optimization_prepare_action or optimization_list_decisions. There is no mention of workflow context, prerequisites, or situations where this tool should be chosen over others. An agent is left to infer its role solely from the name and description.

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