close_cash_tracking_session

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Close' without explaining side effects (e.g., whether it's irreversible, whether endingCash must match the recorded balance, what happens to the session after closing). This is a significant transparency gap for a state-changing 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 a single, concise sentence with no wasted words. It front-loads the core action, which is efficient. However, it is under-specified relative to the tool's complexity, but that is more relevant to completeness than conciseness.

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 incomplete. It doesn't clarify the required ending cash, the business meaning of closing a session, return values, or error conditions. Sibling tools like get_cash_tracking_session provide context, but the description itself fails to give an agent enough to invoke correctly with confidence.

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%, with meaningful descriptions for 'id', 'note', and 'endingCash'. The description adds no parameter-level detail, but the schema already documents the parameters sufficiently, so the baseline of 3 applies.

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 'Close a cash tracking session' uses a specific verb ('close') and resource ('cash tracking session'), clearly distinguishing it from sibling tools like get_cash_tracking_session or create_cash_tracking_session. It is not a tautology and accurately states the action, though it lacks detail about the effect of closing.

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, no prerequisites (e.g., the session must be open), and no exclusions. It merely restates the action without contextualizing it relative to other cash tracking operations like add_cash_transaction or get_cash_tracking_session.

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