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

With no annotations, the description carries the full disclosure burden but delivers almost nothing: no statement about irreversibility, required permissions, side effects on the deposit or product, or whether a rejection can be undone. Only the mutating nature of the verb 'reject' is inferable.

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 single sentence is front-loaded but reflects under-specification rather than genuine conciseness. There is no wasted filler because there is almost no content at all.

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?

A state-changing tool with no annotations, no output schema, and no parameter documentation is left critically underspecified. An agent cannot know what rejecting does, what happens on success, or how it relates to the other deposit-lifecycle siblings.

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 0%, so the description must explain the three parameters, yet it adds nothing. The presence and optionality of 'reason' versus the required product_id/deposit_id pair is undocumented anywhere, leaving the parameter semantics entirely 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 names a specific verb and resource ('Reject a deposit'), which is unambiguous and distinguishable by antonym from the sibling approve_deposit. It does not, however, state scope or consequences (e.g. what rejection entails versus set_deposit_refund_status).

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as approve_deposit or set_deposit_refund_status even though those siblings overlap in the deposit lifecycle. The agent is left to infer all routing.

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