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

The annotations already declare this as a non-readonly, non-destructive, non-idempotent mutation. The description adds useful context that cycle and relationship validation applies and that organizational and business-workflow approval rules may affect execution, but it does not explain side effects, failure behavior, or idempotency beyond the annotations.

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?

Two concise sentences with the creation action front-loaded. The second sentence adds relevant approval context, though it is somewhat generalized.

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?

Although an output schema exists, the input schema has 0% description coverage and a nested data object with several required semantics-heavy fields. For a mutation tool with approval implications, the description does not provide enough parameter or operational context to fully guide correct invocation.

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%, including nested dependency fields such as predecessorTaskId, dependencyType, offsetDays, and date-affecting flags. The description adds no meaning for taskId, data, or any nested parameter, leaving the agent dependent on bare schema names and enums.

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 action, creating a dependency, and the tool name supplies the task-dependency resource. It is clear enough to distinguish from delete/list dependency siblings, but it does not explicitly differentiate itself from those alternatives.

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 no explicit when-to-use or when-not-to-use guidance relative to list_task_dependencies, delete_task_dependency, update_task, or task creation. It mentions validation and approvals, but those are behavioral constraints rather than selection guidance.

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