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

Annotations already declare destructiveHint=true and readOnly=false, and the description does not contradict that. It adds useful non-obvious behavior beyond annotations: deleted concepts leave ads' stamps intact, and the operation respects the active Space or can be overridden for a single call.

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 short, front-loaded with the main action, and every sentence earns its place. It states what happens, the side effect, and the relevant scoping behavior without bloat.

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 destructive annotation, simple two-parameter schema, and absence of an output schema, the description provides enough context for correct invocation: it names the action, the side effect, the Space scoping, and the override mechanism. The only minor gap is no explicit format or semantics for concept_id, but the tool name makes it clear.

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 description coverage is 50%, so the schema fully documents only space_id. The description reinforces the space_id override behavior but does not add much meaning for concept_id, though that parameter is self-evident from the tool name and is the required identifier.

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 names a specific verb and resource: 'Delete a concept.' This cleanly distinguishes it from other delete_* siblings in the tool list, and the side-effect note ('Ads keep their stamp') adds domain-specific clarity about what the deletion does not affect.

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 clearly conveys the operative context: the operation is scoped to the active Space and tells the agent how to change or override that Space via set_active_space or space_id. It does not explicitly list when not to use this tool versus other delete_* tools, but the resource is unambiguous.

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