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

No annotations exist, so the description carries the full behavioral burden. 'Transparent rankings' is marketing phrasing that discloses no mechanism: not whether this is read-only, deterministic, whether it runs full simulations internally, execution cost, or what the ranking is based on. Minimal disclosure for an unannotated 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 front-loaded sentence with no filler. It is efficient, though the brevity comes at the cost of substance rather than being a case of well-targeted concision.

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 seven undocumented parameters, no annotations, and no output schema, the description is far too thin. It does not convey what a 'ranking' contains, how policies are scored, or what defaults mean — an agent cannot reliably construct a call from this.

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 0% and all seven parameters have empty descriptions, so the description must compensate. It only indirectly implies that the _a/_b/_c suffixed parameters correspond to the three policies being compared; pipeline_delay, units, valid ranges, and the meaning of supply_line_weight remain completely unexplained.

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?

States a specific verb (compares) and resource (managerial ordering policies) with a clear scope cap of three. It implicitly distinguishes itself from simulate/optimize/diagnose siblings by being the side-by-side comparison tool, though it never names or contrasts an 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?

There is no when-to-use guidance, no precondition, and no reference to any of the six sibling tools (simulate, optimize, sweep, stability, diagnose, model_info) that a user might pick instead. The agent must infer that this is the multi-policy comparison entry point.

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