+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=false, so the safety profile is covered structurally. The description adds no behavioral context beyond that — it doesn't say what existing styling is lost (overrides? per-slide edits?), that the operation is idempotent and safe to retry, or that it is scoped to one carousel.
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?
A single front-loaded sentence with zero filler, and the destructive verb 'Replace' leads. It is efficient, though the brevity tips into under-specification for a destructive tool.
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 destructive mutation with three sibling 'apply' tools and an undocumented optional workspaceId, the description leaves too much open: it never says whether all slides are re-styled, whether manual edits are lost, or how it differs from carousels_apply_theme. An output schema exists, so return values need not be explained, but the selection and impact gaps remain.
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 only 33% — only projectId carries a (generic 'UUID string.') description, while workspaceId and idempotencyKey are undocumented in the schema. The description compensates for none of this: it doesn't explain the optional workspaceId, nor whether idempotencyKey enables safe retries of this destructive replace.
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?
Names a specific action (replace styling) and the source applied (the workspace's saved brand theme), so the agent knows what the tool does. However, it makes no attempt to distinguish itself from the near-identical siblings carousels_apply_theme and carousels_apply_template, which is the highest-risk confusion for this tool.
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?
There is no when-to-use guidance, no when-not-to-use guidance, and no reference to the alternative 'apply theme' or 'apply template' tools. The agent is left to infer selection purely from the word 'brand' in the name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
