Register a tracked event

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

No annotations are provided, so the description must disclose behavior. It states the tool does not edit files, but it does not clarify whether registering an event has persistent side effects, requires authentication, or is effectively a read-only proposal. The word 'Register' implies mutation, yet the description leaves that ambiguity unresolved.

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 sentences with no filler: the first states the primary action and output, the second adds a key behavioral constraint. Information is front-loaded and each sentence earns its place.

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 tool with 6 parameters, no output schema, and no annotations, this description is incomplete. It omits side effects, response format, required parameter semantics, and any relationship to sibling tools. It is enough to identify the tool but not enough to call it confidently without inspecting the schema.

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 only 33% (2 of 6 properties have descriptions), so the description should compensate, but it adds no parameter-level detail. The reference to window.clarvivo.trackEvent loosely suggests how name, type, and value might be used, but it does not explain url, where, or which parameters are required.

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 ('Register') with a specific resource ('a Clarvivo event') and explains that the tool proposes the exact window.clarvivo.trackEvent call and handler placement. It is clearly distinct from siblings because it is about event registration rather than installation or revenue setup, though it does not explicitly name an alternative.

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 guidance on when to use this tool versus siblings like setup_analytics, connect_revenue, or get_install_snippet. The only contextual clue is 'This tool does not edit files,' which communicates a limitation but not a selection rule or prerequisite.

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