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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety is covered structurally. The description adds real behavioral context beyond that: what a REFUSED result obligates (no publish, no invented audience) and that a positive permission is still gated by a second call for exact wording. It stops short of describing the non-REFUSED outcomes.

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?

Three sentences, all front-loaded with the decision first, then the refusal consequence, then the follow-up requirement. Every sentence carries information, though the phrasing is dense enough to require a second read.

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?

An output schema exists, so return-value details are not required, and the description covers the key decision semantics and the mandatory next step. The main gap is that three of four parameters receive no explanation, which matters at 0% schema coverage.

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 0%, so the description must carry parameter meaning. It implicitly maps the four action enum values to intents (state cause, state timeline, state workaround, publish), which is genuine added value, but boardId, channel, and targetAudience are never explained.

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 (decide) and resource (whether a channel may state a cause/timeline/workaround or publish), so the agent knows this is a policy/gate evaluation rather than a content operation. It also names the sibling evaluate_customer_update, which differentiates it from the other evaluation tool. The only softness is that the evaluated 'resource' is an abstract permission rather than a concrete entity.

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?

It explicitly says when this applies (before stating a cause, timeline, workaround, or publishing) and routes the agent to the correct alternative for exact wording ('still requires evaluate_customer_update for the exact text'). It also gives an explicit when-not: 'REFUSED means do not publish and do not invent an audience.'

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