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

With no annotations, the description carries the behavioral burden; it clearly states that the tool removes a previously set caller_limit, so the core action is transparent. However, it does not disclose side effects, idempotency, auth requirements, or what happens when no caller_limit exists.

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 entire description is one short sentence that names the action and resource in the opening words. There is no filler or repetition of schema details.

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 delete-like tool with a fully documented parameter schema, the description is mostly sufficient. Gaps remain because there are no annotations and no output schema, and the description gives no guidance on prerequisites or consequences of removing the limit.

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 parameters are already documented in the input schema. The description adds no additional meaning about how tool, caller_tenant, or tenant_key interact, but it does not need to compensate for missing schema info.

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 a specific action ('Remove') and a specific resource ('a caller_limit') and anchors it to the counterpart tool ('set by host.share.caller_limit'), which distinguishes it from the sibling setter. Even without a title, an agent can tell exactly what this tool does.

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 this is the inverse of host.share.caller_limit, but it never explicitly says when to use this tool over any alternative or mentions conditions such as needing a tenant_key when no Authorization header is present. Usage context is left to inference.

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