Find open times

find_times
Read-onlyIdempotent

Find the start times that are open for one visit (a service from the card whose bookable is true), between two dates (at most 14 days). Each time's end includes the minutes the business takes to settle the dog in. Pass windows (the customer's free time from their calendar) to get only the starts that fit both calendars. Returns ISO 8601 times with offsets. Only open times are ever shown.

Input Schema

NameRequiredDescriptionDefault
toYesLast day, YYYY-MM-DD. At most 14 days from `from`, counting both, and at most 60 days from today.
fromYesFirst day, YYYY-MM-DD, in the business's time zone (the card names it). Not in the past.
itemsYesExactly one visit. Each visit is booked on its own; add-ons the service takes go in answers.addons.
windowsNoThe customer's free time, as intervals with offsets. When given, only starts whose whole visit (its length plus its settling time) fits inside one window come back. Leave out to see every open start.

TDQS

A4.4/5.0
Behavior4/5

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

Annotations already cover safety (readOnlyHint, idempotentHint, non-destructive, non-open-world), so the bar is lower, and the description still adds real context: the visit's end includes the business's settling minutes, results are ISO 8601 with offsets, the window filter requires the whole visit plus settling time to fit inside one window, and only open slots are ever returned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four tight sentences, front-loaded with the primary action and range cap before the optional-filter detail. "Only open times are ever shown" is mildly redundant with the opening sentence, though it does add an explicit exclusivity guarantee.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only availability query with no output schema, the description covers what it returns (ISO 8601 start times with offsets), what is excluded (booked/closed times), and the window-fitting rule for the optional filter. Nothing an agent needs to call it correctly is absent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds meaning the schema does not spell out as plainly: `windows` is the customer's own calendar availability and, when supplied, only starts fitting both calendars come back — the AND semantics between business availability and customer windows. The 14-day span limit and the one-visit-per-call rule are also reinforced at the top level.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("Find the start times that are open") plus the scope constraint (one visit, a service whose bookable is true, two dates at most 14 days apart). No sibling in the list does availability lookup, and the framing makes clear this is the pre-booking read step rather than book/cancel.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit conditional usage for the optional parameter: pass `windows` to intersect with the customer's calendar, leave it out to see every open start, and the schema repeats that omitting it returns all open starts. It implies the lookup-before-book flow without naming the `book` sibling as the follow-up, so it stops short of full alternative routing.

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