cancel_editing_transaction

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

The description discloses that the in-memory tree is dropped and the on-disk file is unchanged, and mentions the return value. No annotations are present, so the description carries full burden. It lacks details on prerequisites like transaction existence, but is transparent about core behavior.

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 concise with two sentences, front-loading the action and effect. The return value is listed but could be integrated better. Overall efficient and clear.

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's simplicity (one param, no output schema, no annotations), the description covers the main behavioral outcome and return fields. It omits error conditions and prerequisites, but is sufficient for a straightforward cancellation tool.

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 only parameter, transaction_id, is not described in the description beyond being mentioned in the return value. Schema coverage is 0%, so the description should compensate, but it does not provide any additional semantics or guidance on the parameter.

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 it discards a transaction, dropping in-memory tree while keeping on-disk file unchanged. It distinguishes from sibling tools like commit_editing_transaction by explicitly noting the on-disk file is unchanged.

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 explains what the tool does but does not provide explicit guidance on when to use it versus alternatives (e.g., commit_editing_transaction). The usage context is implied by the description of its effects.

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