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

Annotations already cover safety (readOnlyHint, destructiveHint=false, openWorldHint). The description adds genuinely non-structured context: the auth requirement ('Needs the user's Cotlet API key with access to this app') and the default range behavior, which go beyond the 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?

The list of log contents is duplicated almost verbatim ('status dates, lead traffic sources, showings with type and feedback, inquiries, waitlist and vendor entries' repeated as 'It holds status dates...'). This redundancy wastes space and violates the front-loaded, every-sentence-earns-its-place standard.

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 read-only, single-property report with 100% schema coverage and no output schema, the description covers return contents, auth needs and default range adequately. Only explicit sibling routing is absent.

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 coverage is 100% and each parameter is documented ('Default: today', 'Property or unit ID from list_properties'). The description merely restates the from/to default already in the schema and adds no syntax or format detail, so 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 clear verb ('Returns the Activity Log') and resource ('of one property for a date range'), enumerating what the log contains. It is distinguishable from siblings like rently_get_dashboard and rently_list_leads, though it never explicitly contrasts itself with them.

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 default date-range behavior ('Without from and to, it covers up to today'), which is useful implied usage, but offers no when-to-use vs alternative guidance or exclusions relative to the other rently reporting/lead tools.

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