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

With no annotations, the description carries the full burden and does reasonably well: it discloses the return shape ({ id, flowId, version, name }), the side effect that connections and extension catalog are auto-loaded, and how the returned id is consumed later. It omits permissions/auth requirements and failure behavior, which keeps it below 5.

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?

Front-loads the action and the return payload, then tacks on the two field-level notes. Dense with semicolons but no filler sentences; every clause contributes information.

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 simple three-parameter creation tool with no output schema, the description supplies the return fields, the id-reuse contract, and side effects. The main remaining hole is the unexplained required workspaceId, which an agent would have to infer.

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 coverage is 0%, so the description must compensate. It explains name (3-50 characters) and description (optional text stating what the flow does), which is a real gain over an undocumented schema, but workspaceId — a required parameter — is never explained, leaving one of three parameters opaque.

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?

States a specific verb and resource ('Create an empty flow in the workspace') and adds the key modifier 'empty', which distinguishes this from cloning or importing a populated flow. No sibling tool creates flows, so explicit sibling differentiation isn't needed, but it also doesn't contrast with apply_operations or get_flow_json.

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?

Gives actionable downstream context: 'pass id as versionId to later calls' tells the agent this is a setup step for subsequent operations, and notes that connections and the extension catalog load automatically so no extra setup call is needed. It does not state explicit when-not-to-use conditions.

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