delete_transaction_attachment

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

Annotations already have destructiveHint: true. The description adds 'Irreversible', which reinforces the destructiveness but does not add new behavioral context beyond what the annotation provides. No contradiction.

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

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

Extremely concise: two short sentences with no filler. The key action and consequence are front-loaded. Every word earns its place.

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

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

Given the simplicity of the tool (single delete operation) and no output schema, the description covers the essential action and irreversibility. However, it lacks context about the relationship to transactions or where to obtain the file_id. Adequate but not thorough.

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

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

Schema coverage is 100% with a clear description for file_id. The tool description adds nothing beyond the schema. Parameter semantics are sufficiently covered by the schema, so baseline of 3 is appropriate.

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

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

Clearly states the verb 'Delete' and the resource 'transaction file attachment'. Distinguishes it from sibling tools like delete_transaction (deletes a whole transaction) and get_transaction_attachment_url (retrieves attachment URL). No ambiguity.

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

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

Provides no guidance on when to use this tool versus other deletion tools. No mentions of prerequisites, alternatives, or when not to use it. Agent must infer context from the name alone.

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