Transactions Delete Transaction Attachment

transactions_delete_transaction_attachment
Destructive

Remove an attachment from a transaction using its attachment ID, helping manage or clean up transaction data.

Instructions

Delete transaction attachment. This may delete, clear, reset, or otherwise remove data.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",

  "params": {
    "arguments": {
      "attachment_id": "<attachment_id>"
    },
    "name": "transactions_delete_transaction_attachment"
  }
}

TDQS

B3.4/5.0
Behavior3/5

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

Annotations already communicate destructiveHint=true and readOnlyHint=false, so the agent knows this is a destructive mutation. The second sentence vaguely adds that data 'may delete, clear, reset, or otherwise remove data,' but it does not specify what data beyond the attachment or whether deletion is reversible. It neither contradicts the annotations nor provides concrete behavioral detail.

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

Conciseness3/5

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

The first sentence is direct and front-loaded, but the second sentence is largely redundant with the destructiveHint and the first sentence. 'This may delete, clear, reset, or otherwise remove data' is generic filler rather than a precise disclosure. The overall length is appropriate, but not every sentence earns its place.

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 simple delete operation with one required parameter, the schema plus annotations provide most of the necessary context: destructive behavior, idempotency, read-only status, and output shaping. The description is sufficient for an agent to understand the core call, though it omits explicit side-effect scope and usage guidance. A return/value description would be nice but is not essential for a destructive action.

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?

The schema documents fields and output_mode with clear descriptions and examples, covering 67% of parameters. The required attachment_id has no schema description, but its meaning is reasonably inferable from its name and the tool purpose. The description itself does not add any parameter-level meaning beyond the schema.

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 starts with the imperative 'Delete transaction attachment,' which names a specific action and resource. The noun 'attachment' clearly distinguishes it from transactions_delete_transaction and from list/get/upload/download attachment siblings. There is no ambiguity about the operation.

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

Usage Guidelines2/5

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

No guidance is given about when to use this tool versus alternatives, such as downloading the attachment first, removing just the attachment versus deleting the whole transaction, or how to add an attachment back. The agent is left to infer usage entirely from the tool name and sibling list. Destructive preconditions or side effects are not mentioned.

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