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

With no annotations, the description carries the full burden. It explicitly discloses that the operation is destructive and cascades to 'all its snapshots and diff history', which is critical behavioral context. It does not mention irreversibility or permission requirements, but the key side effects are clearly stated.

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, direct sentence that front-loads the action and scope without unnecessary words. Every word earns its place, and the structure is immediately comprehensible.

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 simple one-parameter delete operation with no output schema, the description is adequately complete. It explains what is deleted, including the cascading effect on snapshots and diff history. It could mention error behavior or idempotency, but those are minor gaps given the tool's simplicity.

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 already provides 100% coverage of the parameter meaning with 'Endpoint ID to delete'. The description adds no additional parameter-level detail, so the baseline score of 3 applies; the schema carries the semantic weight.

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 uses the specific verb 'remove' and identifies the resource as 'a monitored endpoint' with explicit scope ('all its snapshots and diff history'). This clearly distinguishes it from sibling tools like compare_snapshots, get_diff_history, and register_endpoint, which serve different purposes.

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 implies usage when deleting an endpoint, but provides no explicit guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. It does not mention that this is the inverse of register_endpoint or that it should be used when permanent removal is intended.

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