Delete an Untappd check-in

untappd_delete_checkin
DestructiveIdempotent

Delete one of your Untappd check-ins permanently by ID. Requires confirmation to prevent accidental loss; returns a preview and confirmation token for two-step approval.

Instructions

Permanently delete one of YOUR check-ins by its id. This is destructive and cannot be undone. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
checkin_idYesUntappd check-in id
confirmTokenNoONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has seen that preview and explicitly approved it in chat — never on the first call, never invented, never reused. Call again with the same arguments. Ignored when the client supports elicitation.

TDQS

A4.5/5.0
Behavior5/5

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

Annotations already flag destructiveHint=true, and the description adds crucial detail: permanence ('cannot be undone'), the requirement to ask the user first, and the preview/confirmToken fallback mechanism. This meaningfully exceeds what the annotations alone convey.

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?

The description is compact and front-loaded: purpose first, then safety, then confirmation mechanics. Every sentence adds necessary information without repeating schema content.

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 destructive tool with no output schema, the description fully covers what an agent needs: what is deleted, irreversibility, user confirmation requirements, and how the confirmToken fallback sequence works. Nothing critical is missing for correct invocation.

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

Parameters3/5

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

Schema coverage is 100%, and both parameters already have detailed descriptions in the schema. The description adds ownership context for checkin_id and relates confirmToken to the confirmation flow, but the schema already carries most of the parameter semantics.

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?

The description states a specific verb and resource: 'delete one of YOUR check-ins by its id'. It clearly scopes the operation to the user's own check-ins, distinguishing it from sibling tools like untappd_delete_comment.

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?

The description clearly says this is a destructive, irreversible action and explains the confirmation flow, including the two-step fallback with a confirmToken. It provides strong context but does not explicitly name sibling alternatives or say when not to use it.

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