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

With no annotations provided, the description carries the full burden. It discloses the priority-based behavior, which is useful context beyond the input schema. However, it doesn't cover other traits like error handling, return format details (though output schema exists), or whether it's idempotent or state-changing.

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 extremely concise with two short sentences that front-load the core purpose and add essential priority context. Every word earns its place, with no wasted text or structural issues.

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 simplicity (0 parameters, output schema provided), the description is complete enough for an agent to understand what it does and the priority order. It could slightly improve by hinting at the return type or error cases, but the output schema mitigates this gap.

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 tool has 0 parameters with 100% schema description coverage, so the schema already documents this fully. The description doesn't need to add parameter details, and it appropriately avoids redundancy, earning a baseline score above 3 for not cluttering with unnecessary info.

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 clearly states the tool's purpose with a specific verb ('Returns') and resource ('first unbuilt item'), making it immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'save_route_plan' or 'write_component_file' which might also relate to project tasks.

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 implies usage by specifying priority order ('Models -> Routes -> Tests'), which suggests when to use it for task sequencing. But it lacks explicit guidance on when not to use it or alternatives among siblings, such as whether to use this for planning vs. execution tasks.

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