Save a checked claim to your Untap account

save_claim

Saves the result of a train, flight or TfL check to the person’s Untap account, so it appears on their dashboard with its deadline. Accepts the save_claim arguments returned by a check, with the price paid added where the check listed it as missing. The verdict is worked out again from those facts rather than copied. A train journey that is already saved is returned as it is, not saved twice. Requires sign-in to Untap.

A4.1/5.0
Behavior4/5

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

Annotations already cover the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false). The description adds genuine context the annotations cannot: sign-in requirement, that the verdict is recomputed from the supplied facts rather than copied, that the missing price must be supplied, and that an already-saved train journey is returned unchanged. The train dedup claim sits in mild tension with idempotentHint=false, but since the hint is general and the description scopes dedup to train only, this is a nuance rather than a contradiction.

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

Conciseness5/5

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

Four tight sentences with no waste; the core action and destination lead, followed by input shape, recomputation behavior, dedup, and the auth prerequisite in descending order of importance.

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

Completeness4/5

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

For a mutation tool with no output schema, the description covers the write, the auth requirement, the input provenance, and the idempotency edge case. It does not describe what the returned claim object looks like (beyond the dedup case), which is the main remaining gap.

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% with deeply documented nested objects, so the baseline is 3. The description adds value on top by explaining that the check's save_claim arguments are passed through and that ticket_price_pence must be filled in where the check omitted it, which is exactly the field the schema marks required for train/flight but not for tfl.

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

Purpose4/5

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

States a specific verb ("saves"), the resource (the result of a train, flight or TfL check) and the destination/effect (the Untap account, dashboard, deadline). It clearly positions itself downstream of a check, but never names the sibling tools (add_train_journey, add_flight, update_claim_status) it must be chosen over, so sibling differentiation is left implicit.

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 real usage context: it consumes the save_claim arguments a check returned, and it requires sign-in to Untap. It also notes the dedup case for train journeys. What is missing is an explicit "use this instead of add_train_journey/add_flight when you already ran a check" contrast against the near-identical add_* siblings.

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