tracesCreateConfiguration

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

Annotations only provide readOnlyHint=false and destructiveHint=false. The description adds meaningful behavioral information beyond that: the recording does not start immediately but on the user's next run, and it discloses the error behavior for a bare parameters ID and a plain date (a flat 400 that does not name the field). This is more than the annotations would have conveyed alone.

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 three reasonably sized sentences with the primary purpose front-loaded. It packs a good amount of detail without resorting to padding, and no sentence is wasted. It becomes a bit dense in the third sentence about normalization and the 400 error, but it is still readable and efficient.

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?

The tool only has a nested config object and no output schema, so the description carries a heavy burden. It does name the fields that are likely needed inside config, which is a good start, but it does not specify types or value enumerations for properties like processType, objectType, expires, or maximalExecutions. An agent might still struggle to construct a syntactically correct config without additional assumptions on the format.

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 single config parameter is described only as an object or JSON string in the schema, so the description adds value by enumerating the nested fields: parametersId, traceUser, traceClient, processType, objectType, expires, and maximalExecutions. It goes further to state that a bare parameters ID and a plain date are normalized, providing practical constraints better than the generic schema. However, it still does not define exact value types or allowed formats for each nested property.

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 and resource: "Create a trace configuration: which user and which process to record, and for how long." It clearly differentiates the tool from related trace tooling by specifying the creation intent and the key trigger condition (recording starts when the user next runs something). It also frames the input as the output of a sibling, tracesSetParameters, removing ambiguity.

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 gives a clear context for use: creating a trace configuration, and it explicitly states a prerequisite: a parametersId from tracesSetParameters. It does not, however, explicitly contrast with alternatives—for example it does not say "use tracesDeleteConfiguration to remove a trace"—so it falls short of the highest bar, but it is still more actionable than a generic one-line purpose.

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