Create Tracker entity

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

Annotations already cover readOnlyHint=false, destructiveHint=false, openWorldHint=true, idempotentHint=false, so the safety profile is declared. The description adds the useful note that the created entity is returned with its id, which is context beyond annotations, but says nothing about auth scope, required fields at runtime, or side effects.

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?

Single tight sentence that front-loads the verb, resource, subtypes, and the return value. No filler.

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 3-parameter mutation with a nested body and no output schema, the description is minimal. Annotations cover the safety profile and the schema is fully documented, but the description could clarify hierarchy (parentEntity vs entity_type), required field behavior, and return shape details. Adequate but with clear 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?

Schema description coverage is 100%, including nested field docs and 'summary is required on create', so the schema carries the parameter burden. The description adds no parameter detail beyond 'returns it with its id', making baseline 3 appropriate.

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?

States a specific verb and resource ('Create a Tracker entity') and enumerates the three subtypes (project, portfolio, goal), which matches the entity_type enum-like description in the schema. It does not explicitly differentiate from siblings like tracker_entities_update or tracker_projects_create, but the create semantics are unambiguous.

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 when-to-use guidance, no mention of alternatives such as tracker_projects_create for project-specific creation, and no prerequisites (permissions, parent entity requirements). The agent must infer all routing from the name.

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