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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the write/destructive profile is covered. The description still adds real value beyond them: it confirms the replacement semantics, notes earlier versions stay restorable in the app, and states that invalid input returns field-level errors. It does not describe auth requirements or rate limits.

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?

It is front-loaded with the core action before descending into content and timing constraints, and most sentences carry information an agent needs (timing math, element ordering, validation behavior). It is dense and long, with a few details that would sit better as schema annotations, but little is pure 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?

For a deeply nested, destructive tool with no output schema, the description covers content constraints, style sourcing, timing rules, replacement/restore behavior, and error reporting. The only gap is that it does not characterize a successful return, which slightly matters given the absence of an output schema.

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% and the schema itself fully enumerates the nested brand/scenes structure, so the baseline is 3. The description adds conceptual meaning (brand derives from logo and product styles, story comes from the delivery summary) but gives no field-level syntax or defaults beyond what the schema already encodes.

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 opens with a specific verb+resource ('Save a delivery's release presentation') and immediately characterizes the artifact and its rendering surface (Public Delivery Page, brand's style). It distinguishes itself from the get/delete/update siblings by framing the operation as a save that replaces the current presentation.

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 through the artifact's purpose and the note that it 'Replaces the current presentation,' but the definition never states when to choose this over update_delivery, get_delivery_presentation, or delete_delivery_presentation, nor any prerequisites. The agent must infer routing from sibling names alone.

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