get_worker_balance

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

With no annotations and no parameters, the description carries the burden of disclosure. It does reveal that the result is a prioritized staffing suggestion derived from comparing idle jobs against current distribution, which is genuinely useful behavioral context. It does not say whether the tool is read-only, where the underlying data comes from, or how the ranking is computed, leaving notable gaps for a zero-annotation tool.

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?

A single compact sentence with no filler, and the core action is front-loaded. It is efficient, though it could have spent the same length on when-to-use guidance instead.

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?

With zero parameters and no output schema, the description must convey what comes back, and it only broadly characterizes the result as a suggested staffing order. It says nothing about the form of the response (ranked list, per-site detail, reasoning) or the data sources consulted, leaving the agent under-informed about interpreting the output.

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 takes no parameters, so there is nothing for the description to disambiguate. The baseline of 4 applies since no parameter semantics are required.

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 gives a verb pair ('compare', 'suggest') and names a domain ('idle construction jobs', 'job distribution'), so the general function is graspable. However, it never states the resource the tool reports on in the terms of its own name (worker balance), and it does not distinguish itself from plausible siblings such as get_recommendations or get_mission_plan, which likely also produce suggestions. The mismatch between name and described behavior forces the agent to guess which framing is authoritative.

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?

There is no indication of when this tool should be called, what preconditions apply, or which alternative to prefer. No exclusions or alternatives are named, so the agent has no routing signal beyond the vague phrase 'staff first'.

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