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

Goes well beyond the annotations (readOnlyHint=false, destructiveHint=false) by disclosing concrete side effects: testers cannot submit answers or open tickets, the beta displays as paused, managers retain sketch-mode editing, and no emails are sent. It also flags reversibility, which is exactly the context an agent needs before a state mutation.

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 tight sentences, front-loaded with the action and its precondition, followed by effects and reversibility. No filler or redundancy.

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 one-parameter state-mutation tool with no output schema, the description covers precondition, side effects, notification behavior, and reversibility. Nothing an agent needs to invoke it correctly is missing.

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 100% for the single productId parameter, so the schema already carries the semantics and the description adds nothing about the parameter. Baseline 3 applies since the description does not supplement the parameter documentation.

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?

States a specific verb ('Pause') and resource ('this RUNNING beta project') with an explicit precondition on state. An agent can distinguish it from siblings like resumeBeta, archiveBeta, and launchBeta without opening any schema.

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?

Gives a clear precondition (project must be RUNNING) and names the counterpart tool 'resumeBeta' as the way to reverse it, which routes the agent well. It does not explicitly exclude archiveBeta or restoreBeta, so the alternative-space is not fully enumerated.

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