Save Canvas Project

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

The description adds useful behavioral details beyond the annotations: atomicity (all-or-nothing save), validation of the project, and externalization of image data to content-addressed assets. These are not covered by the annotations and do not contradict them, enhancing the agent's understanding of side effects.

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 two sentences long and front-loaded with the core action ('Atomically save a validated Canvas project'). Every sentence adds meaningful information without unnecessary detail or repetition.

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 complex nested project parameter and zero schema coverage, the description lacks structural detail and validation specifics. However, the existence of an output schema and annotations partially compensates, making the description moderately complete but with clear gaps.

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 schema has zero description coverage for the 'project' parameter, and the description only refers to a 'validated Canvas project' without specifying its structure, required fields, or validation criteria. This is insufficient guidance for an agent to construct a valid parameter object.

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 the tool atomically saves a validated Canvas project within the bound workspace, using a specific verb ('save') and resource ('Canvas project'). It effectively distinguishes itself from sibling tools like save_canvas_asset, which saves individual assets.

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 implies the tool is for saving a whole project, but it does not explicitly state when to use it versus alternatives or provide exclusions. The mention of 'validated' suggests a precondition, but no alternative tools are named or contrasted, leaving usage guidelines implicit.

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