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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds the post-deletion outcome 'restoring normal responses' but omits irreversibility, auth, or operational impact detail, so it adds limited value beyond annotations.

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?

One front-loaded sentence with no filler; both deletion modes and the effect are packed efficiently.

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?

Low-complexity two-param destructive tool; annotations carry safety and schema carries parameters. The description covers both deletion modes and outcome, though it could point to list_fault_rules for discovering rule_id. Complete enough for correct invocation.

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 both rule_id and workspace are already documented. The description repeats the omit-rule_id behavior without adding format or semantics beyond the schema; baseline 3 applies.

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 'fault rule(s)' with workspace scope and effect ('restoring normal responses'), making it easy to separate from list_fault_rules and set_fault_rule. Does not explicitly name siblings, so it is clear but not fully differentiating.

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?

Gives two operating modes (single rule_id or all rules in workspace) but no explicit when-to-use guidance or alternatives, such as using set_fault_rule to edit instead of delete. Usage is implied by the operation itself.

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