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

Annotations already declare destructiveHint=true and readOnlyHint=false, so safety semantics are covered. The description adds nothing beyond them: it does not state that the deletion is irreversible, what happens to linked interface contracts by default, or any permission requirements, so it contributes no behavioral context the annotations lack.

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?

A single front-loaded sentence with no filler, so nothing is wasted. However, for a destructive operation the brevity crosses into under-specification rather than genuine conciseness.

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?

The operation is simple, the schema fully documents inputs, and an output schema exists so return values need not be explained. Still missing is any usage or consequence context for the cascade option and irreversibility, leaving a modest gap for a destructive tool.

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 100%, so all three parameters are already documented, including the cascade_interface_contracts flag. The description only reinforces the UUID-based selection, which is the expected baseline 3 when the schema does the heavy lifting.

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?

States a specific verb (delete) and resource (subsystem) plus the identification mechanism (UUID), which cleanly distinguishes it from siblings like subsystems_get, subsystems_update, and subsystems_list. It does not explicitly name those siblings, but the CRUD naming makes the operation unambiguous.

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?

There is no when-to-use guidance, no exclusions, and no mention of when cascade deletion is appropriate versus deleting interface contracts separately. The agent must infer everything from the tool name and schema.

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