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

Annotations only give readOnlyHint=false, destructiveHint=false, openWorldHint=true. The description adds real context beyond that: the operation reaches other people and therefore requires per-call user confirmation, confirmation can be disabled, and the call needs a Cotlet API key scoped to this app. It stops short of stating irreversibility or what happens to the request record afterward.

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 core action and effect are front-loaded, but the clause 'the prospect gets access to tour the property' is stated twice in the opening sentences, which is redundant and dilutes an otherwise compact definition.

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 single-parameter write tool with no output schema, the description covers the effect, the auth requirement, and the human-confirmation obligation. Minor gaps remain around reversibility and the resulting state of the request, but nothing essential to invoking it correctly is missing.

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% and the ID parameter already documents its source ('Request ID from list_safe_mode_requests'). The description only restates that it acts on 'one pending' request, adding no format or sourcing detail beyond the schema, so the 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?

The description names a specific verb (approve/grant) and resource (Safe Mode request/access) and states the outcome ('the prospect gets access to tour the property'). It is distinct from read siblings like rently_list_safe_mode_requests, though it never names rently_dismiss_safe_mode_request, its natural opposite.

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 says it approves 'one pending Safe Mode request,' which implies the request must already exist (and the schema points to list_safe_mode_requests for the ID). However, there is no explicit when-to-use/when-not guidance versus dismiss_safe_mode_request or the self-tour tools, so the agent must infer the routing.

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