Receipts Upload Receipt

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

Annotations already declare readOnlyHint=false, so the description's statement that it 'may create or update Monarch data' adds useful context about the kind of write operation. However, it does not disclose file handling behavior, required permissions, or what happens to an uploaded receipt.

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?

The description is very concise with no filler and places the core action first. The opening sentence is somewhat redundant with the title, but the second sentence adds useful behavioral context without unnecessary detail.

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?

With no output schema and only a two-sentence description, an agent cannot determine what the tool returns, what file formats or paths are accepted, or how the uploaded receipt relates to transactions or matching workflows. The write behavior is annotated, but operational context is missing.

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 description coverage is only 40%, and the tool description adds no parameter-level meaning beyond the schema. The required file_path parameter is undocumented in both the schema and description, and filename and content_type are also unexplained.

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?

The description states the specific action 'Upload receipt' and clarifies the effect as creating or updating Monarch data. This distinguishes it from sibling receipt tools by the verb 'upload', though the first sentence largely restates the title.

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?

No guidance is given about when to use this tool versus alternatives such as receipts_match_receipt, receipts_update_receipt, or transactions_upload_transaction_attachment. Usage is only implied by the tool name and description, not explicitly stated.

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