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

No annotations are provided, so the description carries full burden. 'List iterations/sprints' implies a read-only operation but doesn't disclose behavioral traits like pagination, sorting, filtering, rate limits, authentication needs, or return format. For a tool with zero annotation coverage, this leaves significant gaps in understanding how it behaves.

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 a single, efficient phrase ('List iterations/sprints') with zero wasted words. It's front-loaded with the core action and resource, making it immediately scannable. Every word earns its place by conveying essential purpose.

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?

Given the tool's complexity (listing iterations/sprints likely involves multiple items), lack of annotations, and no output schema, the description is incomplete. It doesn't explain what 'iterations/sprints' entails (e.g., metadata included), how results are structured, or any constraints. For a read operation with no structured support, more context is needed.

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 input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description doesn't add parameter details, which is appropriate. A baseline of 4 is assigned since the schema fully covers parameters, and the description doesn't need to compensate.

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 'List iterations/sprints' clearly states the verb ('List') and resource ('iterations/sprints'), making the purpose immediately understandable. It distinguishes from siblings like 'get_current_sprint' (singular) and 'get_sprint_work_items' (work items within sprints). However, it doesn't specify scope (e.g., all iterations vs. current project), which prevents a perfect score.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, context (e.g., project-specific), or compare to siblings like 'get_current_sprint' for a single sprint or 'list_work_items' for broader queries. Without usage instructions, the agent must infer context from tool names alone.

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