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

Annotations cover the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=true), and the description adds real context beyond them: per-call confirmation is on by default but switchable, the action affects other people, and a Cotlet API key with app access is required. It does not state reversibility of a dismissal, so not a full 5.

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?

Front-loaded with the action and effect, and the policy sentences are useful rather than filler. Minor redundancy: sentence one restates the title and sentence two largely repeats it before adding the consequence.

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 mutation with annotations and no output schema, the description covers purpose, external impact, confirmation behavior, and auth requirements. It stops short of covering failure modes (e.g., an already-approved or expired request).

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?

Only one parameter (request_id) and schema description coverage is 100%, with the schema itself pointing back to list_safe_mode_requests. The description adds no format or sourcing detail beyond the schema, so the baseline of 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 states a specific verb and resource — 'Decline a Safe Mode viewing request' — and clarifies scope ('Declines one pending Safe Mode request'), which cleanly separates it from siblings like rently_grant_safe_mode_access and rently_list_safe_mode_requests.

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 makes the trigger condition clear ('one pending Safe Mode request') and adds a confirmation policy, but never names the alternative tools (grant access, list requests) or states when dismissal is inappropriate versus granting access. Context is clear without explicit exclusions.

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