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

No annotations are provided, so the description carries the full behavioral burden. It does not disclose idempotency, whether retries duplicate fulfillment/side effects, required permissions, or failure handling — significant gaps for an action/mutation tool with zero annotation coverage.

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?

A single front-loaded sentence with no wasted words. However, it is under-specified rather than genuinely concise — too little content for the tool's operational complexity.

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?

For an action tool with no annotations, no output schema, and fully undocumented parameters, the definition is incomplete. An agent lacks the permission, side-effect, and identifier details needed to invoke it safely.

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?

Two required parameters at 0% schema description coverage, and the description offers no semantics for deposit_id or product_id. It does not compensate for the schema gap or clarify which identifiers are expected.

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?

States a specific verb and resource ('Resend/retry fulfillment') plus the qualifying condition ('for an approved deposit'). It is clearly distinguishable from approve_deposit/reject_deposit, though it doesn't name a sibling it might be confused with.

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?

The phrase 'for an approved deposit' implies a precondition (the deposit must already be approved), but there is no explicit when-to-use vs when-not, no mention of alternatives, and no guidance on repeated retries.

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