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

Annotations already declare this as a safe, idempotent read. The description adds useful context that it returns only one level deep and requires the tasks:read API scope, but it omits pagination behavior, ordering, and return-shape details.

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 definition is front-loaded and compact: one sentence for the operation and one for the API-key scope. Every sentence carries useful information with 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 simple read-only list endpoint with annotations covering safety, the core purpose is clear. Still, with five parameters and no output schema, the undefined limit/cursor semantics and missing usage alternatives leave gaps for an agent calling it correctly.

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 coverage is only 60%, with limit and cursor undocumented in both schema and description. The description says 'by ref' and clarifies the ref is a parent task, but adds no meaning for the pagination parameters or the account/workspace context beyond the schema text.

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: list direct subtasks of a parent task, with the important one-level-depth scope. It is clearly distinguishable from broader task-fetching tools, though it does not explicitly name a sibling alternative.

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?

Usage is implied: call this when you have a parent task ref and need its immediate children. However, it does not say when to prefer this over pm_get_task, pm_search_tasks, or relationship-listing tools, and gives no exclusions.

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