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

Annotations already declare a read-only, idempotent, closed-world read, so the safety profile is covered. The description adds real domain context — that some dates exist upstream of the rental tool (pushId) and some are owner-closed (claimId) — but says nothing about pagination, empty windows, or what the response shape looks like, and there is no output schema to lean on.

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?

It is a single sentence with no filler, which is good, but the compression is excessive: the parenthetical claimId/pushId clauses are cryptic to a reader who has not seen the response. Density is traded against comprehension.

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 tool with four required parameters and no output schema, the description should carry the return-value burden. It gestures at the important fields (claimId, pushId) and the window limit, but never explains the structure of returned dates per home, so an agent cannot predict the response.

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 four parameters are already documented, including the YYYY-MM-DD format and the 62-day bound. The description only obliquely implies slug identifies a collection ('a collection's homes') and adds no format or constraint 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 names a concrete resource — booked and closed dates for a collection's homes — and distinguishes data provenance types (owner-closed dates carrying claimId vs. not-yet-pushed dates carrying pushId). It never states a verb and never names calendar siblings such as set_dates or share_calendar_link, so it stops short of a 5.

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?

There is no when-to-use guidance and no routing to alternatives; an agent looking to change availability must infer on its own that set_dates (not this tool) is the mutation counterpart. The only implied context is the 62-day span limit.

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