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

The annotations already establish a safe, read-only, idempotent operation, while the description adds limited result context by mentioning governance and validation rules. It does not clarify whether those rules are returned or used as filters, nor disclose pagination, ordering, or other result-scope behavior.

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 statement is front-loaded with the operation and resource and contains no filler. However, its compressed wording leaves “with governance and validation rules” ambiguous and omits scope that could have been stated briefly.

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?

This is minimally adequate for a simple one-parameter, read-only listing whose safety behavior is covered by annotations. The lack of an output schema and parameter documentation makes the ambiguous rule content, missing workspace scope, and absent differentiation from related tracking-plan tools meaningful gaps.

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?

With 0% schema description coverage, the description needed to explain the sole workspace_id parameter, but it never mentions workspace scoping or how to obtain the ID. The parameter name is reasonably self-explanatory, but the description itself adds no parameter semantics.

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 gives a specific verb and resource—listing tracking plans—and adds governance and validation rules as relevant content. It does not distinguish this tool from siblings such as get_source_tracking_plans_and_versions or list_tracking_plan_events.

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 explicit when-to-use guidance, prerequisite, or alternative-tool routing. An agent must infer that this is for general tracking-plan discovery rather than event-, violation-, or source/version-specific queries.

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