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

Annotations already indicate destructive and non-read-only behavior. The description adds valuable specifics: 'controlled staging', 'insert or replace', 'persist project assets', and 'clean temporary uploads', giving the agent a clear mental model of what side effects occur. No contradiction with annotations.

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 entire description is a single, dense sentence with a clear sequence of actions. Every phrase carries meaning, with no filler or redundant content.

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 output schema exists and annotations cover safety, the description sufficiently outlines the tool's multi-phase behavior. It does not elaborate on failure cases or the 'confirmTargetOverride' parameter, but the main purpose is covered.

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 0%, and the description provides no parameter-level details. While 'taskId' is self-explanatory, 'confirmTargetOverride' is completely unexplained, forcing the agent to guess its meaning. The description focuses on overall actions rather than parameter semantics.

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 enumerates concrete actions (download, insert/replace, persist, clean) and resources (successful task, Canvas objects, project assets, temporary uploads), making it distinct from sibling tools like submit or get. The verb 'finalize' is not used, but the multi-step language unambiguously establishes this as the completion step.

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 'Download a successful task' sets an explicit precondition, implying this tool is for post-success finalization. It does not name alternatives or say when not to use it, but the context is clear enough for an agent to select it as the finalization step.

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