Gtm Transformation

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

With no annotations, the description carries the full behavioral burden. It discloses the confirm=true requirement for remove/revert, which is a meaningful safety-relevant behavior, and lists destructive-sounding actions. It does not explain side effects, required permissions, or response characteristics, so it is only partially transparent.

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 a single compact sentence that front-loads the resource and action set; there is no filler or repetition. The reference to gtm_tag is efficient but slightly cryptic for an agent that has not already read that tool's definition.

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?

Despite an output schema, the input side is underspecified: six parameters, a required action, no parameter descriptions, and no behavioral context. An agent would struggle to know how to construct an object for the various actions. The description covers surface-level operations but not enough to invoke complex actions confidently.

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 explain parameters, but it only implies that confirm gates remove/revert. It leaves path, action, config, params, and parent effectively undefined except by name, so an agent cannot determine what values to pass without additional context.

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 names a specific resource (GTM transformations), scopes it to a workspace, and enumerates the supported operation set (create, get, list, update, remove, revert). It is not a tautology and gives an agent enough to distinguish this from the sibling tools by resource type, though it does not define what a transformation is.

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 establishes the tool covers GTM transformations and that its action set mirrors gtm_tag, which gives some sense of appropriate context. However, it never states when to choose transformation over another sibling, nor any conditions or exclusions beyond the confirm requirement.

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