Update colors

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true, so the write semantics are covered. The description adds only "Changes account configuration," which is marginal and omits the account-wide blast radius, reversibility, and the confirm requirement for delivery/audience changes.

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 short and front-loaded, but the second sentence ("Changes account configuration") is low-value filler that consumes the space where a scope or confirmation note should be.

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 mutation tool with nested payload support and a confirmation gate, two vague sentences are not enough. It omits that changes are account-level, that confirm may be required, and how payload/payload_file interact with the body flags.

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 the schema already documents colors, account, confirm, payload and payload_file thoroughly. The description adds nothing about parameters, but the baseline of 3 applies when the schema carries the semantic load.

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?

"Update colors" simply restates the tool name and title; the only added content is "Changes account configuration," which is broad and vague. It does not distinguish this from the sibling list_colors or explain what scope of configuration is affected.

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, when-not-to-use, or alternative guidance. An agent gets no signal on why it would call update_colors instead of list_colors or update_broadcast, and no prerequisites or confirmation workflow are mentioned.

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