vtex_create_gift_card_transaction

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this is an 'Add' operation (implying mutation) but doesn't cover important aspects like required permissions, whether transactions are reversible, rate limits, error conditions, or what happens to gift card balance after the operation. The description is minimal and lacks behavioral context.

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 extremely concise - a single sentence that directly states the tool's purpose. There's zero wasted language or redundancy. It's front-loaded with the core action and could serve as a model of efficiency for simple tools.

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 a mutation tool with no annotations and no output schema, the description is inadequate. It doesn't explain what happens after the transaction is added, what the response looks like, error handling, or important behavioral constraints. Given the complexity of financial transactions and lack of structured safety information, the description should provide more context about the operation's implications.

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 100%, so the schema already documents all parameters well. The description adds minimal value beyond what's in the schema - it mentions 'credit or debit' which aligns with the operation enum, but doesn't provide additional context about parameter usage, relationships, or business rules. Baseline 3 is appropriate when schema does the heavy lifting.

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 clearly states the action ('Add transaction') and resource ('to gift card'), specifying it can be credit or debit. It distinguishes from sibling tools like vtex_create_gift_card (which creates the card itself) and vtex_get_gift_card (which retrieves information), but doesn't explicitly mention these distinctions in the description text.

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 description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing gift card), when to choose credit vs. debit operations, or how this differs from related tools like vtex_get_transaction. Usage context is implied but not stated.

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