OverviewDiscussionsAdmin

Read this booking and offer timeline

get_booking_history
Read-onlyIdempotent

Use this when retrieving the OAuth-selected booking's recorded offer, change and cancellation events. Do not use for current state (use get_booking_status instead); unpaid checkout uses get_booking_payment_review. Keep the same booking selection while following nextCursor via after. Each page has its own observedAt cutoff, so pagination is not a frozen snapshot. Access is checked around one bounded stored-event query, without provider refresh. An empty page means no matching visible events; unavailable leaves history unverified. Events do not prove payment, refund or fulfillment.

Input Schema

NameRequiredDescriptionDefault
afterNoOmit for the newest page. For older events, copy the preceding non-null nextCursor unchanged. Stop when nextCursor is null.
limitNoMaximum entries in this page, 1–50; defaults to 20. The selected booking stays unchanged.
bookingKeyNoOmit to use exactly the booking already selected by this OAuth connection. If supplied, use that same booking's ID or visible reference; another identifier cannot switch selection or grant access.

TDQS

A4.8/5.0
Behavior5/5

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

Goes well past the readOnly/idempotent annotations: access is checked around one bounded stored-event query with no provider refresh, each page has its own observedAt cutoff so pagination is not a frozen snapshot, and events do not prove payment, refund or fulfillment. It also explains what 'empty' and 'unavailable' mean operationally, which is rare and valuable.

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?

Front-loaded with the use case and the exclusions, and nearly every clause carries distinct information. The last three sentences are dense and slightly clipped ('unavailable leaves history unverified'), which costs a little readability but not meaning.

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?

With an output schema present, the description need not describe return values, and it correctly focuses on pagination behavior, selection semantics, access model, and interpretation caveats. Nothing an agent needs to call this correctly is missing.

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 semantics the schema does not: the cursor must be followed while holding the same booking selection, and the page cutoff semantics of 'after'. It does not restate the limit range or the bookingKey fallback, which the schema handles.

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: retrieving the OAuth-selected booking's recorded offer, change and cancellation events. It immediately separates itself from get_booking_status (current state) and get_booking_payment_review (unpaid checkout), so an agent can pick the right tool without reading schemas.

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

Usage Guidelines5/5

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

Gives an explicit use case plus two named negative cases with the sibling to use instead. It also states the operative constraint for continuation ('keep the same booking selection while following nextCursor via after'), which is the when/how guidance an agent actually needs.

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