execute_operation

Executes a version-negotiated typed operation through a durable engine, using the operation UID as retry identity so conflicting or uncertain attempts are never duplicated.

Instructions

Execute one version-negotiated typed operation through the durable engine.

The exact operation UID is the retry identity. Changed content conflicts; an uncertain attempt is never sent again.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Behavior3/5

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

With no annotations, the description carries the behavioral burden. It adds useful transparency by disclosing that the operation UID is the retry identity and that uncertain attempts are never re-sent, plus the durable-engine framing implies persistence. However, it does not state whether the tool has side effects, requires specific permissions, or what happens on success/failure beyond the conflict note.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded with the main purpose, followed by three short sentences that carry substantive retry and conflict semantics. It avoids filler, though the second and third sentences are somewhat cryptic and could be clearer without adding length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having an output schema and a complex nested input schema, the description omits essential context: how to construct operation and client_offer, what version negotiation entails, when to use this instead of recovery tools, and what external effects execution has. It is not complete enough for an agent to confidently invoke the tool correctly in many scenarios.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description should compensate by explaining the top-level operation and client_offer parameters. It only obliquely references 'operation UID' and 'version-negotiated', without clarifying how to construct or select values for the two required object parameters. The description adds minimal parameter-level meaning beyond the raw schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb-resource pairing ('execute one ... typed operation') and names the durable engine, which makes the tool's core purpose identifiable. It does not explicitly differentiate itself from siblings like recover_operation or release_operation_risk, but 'execute' and 'durable engine' convey enough to separate it from the dominant getter tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus alternatives such as recover_operation or get_operation_status. It implies usage for 'operations' but never states the trigger conditions, prerequisites, or when not to use it. The retry semantics are explained, but not as usage direction.

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