create_series

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state permissions required, side effects, persistence behavior, defaults, or what is returned after creation, which leaves important mutation behavior undocumented.

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 front-loaded sentence with no wasted words. It immediately communicates the action and the created resource.

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 schema is rich and fully documented, which compensates for some gaps. However, for a creation tool with no annotations and no output schema, the description omits expected return behavior, side effects, and relationship to existing sketches, leaving the agent with an incomplete behavioral picture.

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 100%, so all six parameters are already documented in the input schema. The description reinforces narrative, intent, and workflow stages but adds no meaningful syntax, constraints, or semantics beyond what the schema provides.

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 states a specific verb and resource: creating a curated series of sketches, with narrative, intent, and workflow stages. It implicitly distinguishes itself from single-sketch tools by saying 'series,' but does not explicitly name or contrast a sibling tool such as create_sketch.

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?

Usage is implied by the phrase 'Create a new curated series,' suggesting it should be used when grouping sketches into a series. However, there is no explicit when-to-use guidance, no exclusions, and no comparison to alternatives like create_sketch, save_sketch, or series_summary.

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