test_chat_hook

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

There are no annotations, so the description must fully disclose behavior. It only states 'Test an AI chat hook' and the plan requirement, without explaining whether the hook is actually invoked, what side effects occur, or what the response/result looks like.

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?

The description is two short sentences, front-loaded with the core action 'Test an AI chat hook' and no filler. The 'PRO+ plan' note is a concise, relevant constraint.

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 test tool with no annotations, no output schema, and an empty input schema, the description is too thin. It lacks context about what a test does, what result to expect, and how this differs from test_webhook, leaving significant gaps for an agent.

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?

The input schema has zero parameters and trivially 100% description coverage, so the 0-parameter baseline of 4 applies. The schema includes additionalProperties: true, but with no defined parameters, the description does not need to add more.

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 'Test an AI chat hook' uses a specific verb and resource, clearly indicating the tool's action. However, it does not distinguish itself from similar siblings like test_webhook or describe what 'test' entails, so it stops short of a 5.

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?

No guidance is provided on when to use this tool versus alternatives, prerequisites, or expected conditions. The only additional note is 'PRO+ plan', which is a plan restriction, not a usage guideline.

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