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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered; the description adds real context beyond that by stating who is affected (each staff member in the Team Inbox) and who is exempt (owners always see the full table). It still doesn't say the setting overwrites the prior configuration for all staff or whether it takes effect immediately, which is what an agent would want before a destructive write.

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 compact paragraph with three value clauses and no filler. The terse "tone blunt =" / "hidden =" shorthand is efficient, though the sentence structure is slightly telegraphic and the setting-overview lead-in precedes any statement of what the tool does.

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 no-output-schema mutation tool, the description covers the setting semantics well but omits the response behavior, required permission level, and any mention of the read-side siblings. The gap around scope of effect (all staff vs one) and reversibility is the main shortfall for a tool flagged destructive.

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 coverage is only 33%, but the description compensates well: it defines both enum values of `tone` (blunt = rank, points and reply speed; friendly = rank and points with an encouraging line) and clarifies the otherwise cryptic `hidden` boolean as suppressing all of it. Only `brand` is left to the schema, which does describe it adequately.

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 title plus description make clear this configures staff visibility of the weekly scoreboard, and the description spells out what each setting produces. However, the description itself never states the action verb ("set"), opening instead with a description of the current state, so an agent must infer from the title that this is a mutation. It also doesn't distinguish itself from the sibling set_tone, which shares the word "tone."

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 explains the effect of each option but never says when to call the tool, what prerequisite or permission level is needed, or which sibling to use instead. With set_tone, get_team_board, and get_my_standing nearby, the agent gets no routing guidance and must infer that this is the write counterpart to the read tools.

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