ncloud_sourcedeploy_approve_canary

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 states the action 'Approve' without revealing side effects, irreversibility, permissions, or dependency on prior analysis steps. For a mutating operation, this is a significant gap.

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 sentence that starts with the verb 'Approve' and immediately conveys the action and target. Every word is necessary, with no redundancy or filler.

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?

The tool is part of a canary deployment workflow, as evidenced by sibling tools like reject_canary and get_canary_analysis_steps. The description does not explain the workflow context, prerequisites, or consequences of approval. With no annotations or output schema, this leaves the agent without enough information to use the tool correctly in a multi-step process.

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 provides descriptions for all three parameters (projectId, stageId, scenarioId), achieving 100% schema coverage. The description adds no additional parameter-level meaning, so it meets the high-coverage baseline of 3.

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 uses a specific verb 'Approve' and identifies the resource as 'a manually analyzed canary version deployment', which clearly distinguishes this tool from siblings like reject_canary or get_canary_analysis_report. The qualifier 'canary' and 'manually analyzed' narrows the scope precisely.

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 phrase 'manually analyzed' implies this tool is used after a human has reviewed canary analysis, providing some contextual guidance. However, it does not explicitly state when to use this over alternatives like reject_canary or approve_deploy, nor does it mention exclusions or prerequisites.

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