create_transaction

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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It only says 'create', which implies a mutation, but does not disclose any side effects, validation rules, or return behavior. No mention of what happens on success, whether the transaction is immediately posted, or if there are dependencies between fields. This is critically insufficient for a write operation.

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 overly terse—a single sentence that merely repeats the tool name and a few enum values. This is under-specification rather than proper conciseness; it lacks essential details an agent needs. While it is front-loaded, the content is too minimal to be considered appropriately sized.

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 tool has 8 parameters (5 required), no output schema, and no annotations, the description is severely incomplete. It fails to explain how a 'simple' transaction differs from a split one, the meaning of source/destination names, the default behavior for date, or any constraints. An agent cannot reliably construct a valid call from this description alone.

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?

The input schema has 8 parameters but only 13% schema description coverage (just 'date' has an inline description). The description adds no information about any parameters, including required ones like type, amount, description, source_name, and destination_name. It does not explain the meaning of these fields or their relationships, so agents have no textual guidance beyond the schema skeleton.

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 verb 'Create' and resource 'transaction', and specifies the three allowed types (withdrawal, deposit, transfer). This differentiates it from sibling tools like create_split_transaction, which is evident from the name and description. However, it could be more explicit about what 'simple' means in contrast to a split transaction, but it's still specific enough.

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 on when to use this tool versus alternatives like create_split_transaction or update_transaction. The word 'simple' implies a contrast but does not explicitly state the conditions for choosing this tool over others. No prerequisites or context about required fields are mentioned.

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