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

No annotations are provided, so the description carries the full behavioral burden, yet it says nothing about what the tool returns, whether results are ranked, or that it is a read-only query. Only a vague implication of 'find quotations of triggers' exists; behavioral traits are essentially undisclosed.

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?

One front-loaded sentence beginning with 'Use when' with no filler; the examples are useful. It is somewhat list-heavy but every clause earns its place.

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 lookup tool with no output schema, no annotations, and a nested constraints object, the description should hint at the return set and the meaning of process_id. It covers the trigger well but leaves output and key parameter semantics unspecified.

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 33%, so the description must compensate. It loosely references the constraint dimensions (lead time, cost, material), which map to max_lead_days, cost_tier and material_id, but the required process_id and the nested constraints object are not explained.

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 examples ('what can replace FDM', 'alternative to CNC') make the intent clear: return alternative manufacturing processes for a given part/process. However, it never states a clean verb+resource purpose directly and does not distinguish itself from siblings like compare_processes or get_material_process_compatibility.

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?

Strong when-to-use triggers are given: replace a process, switch due to lead time/cost/material constraints. It lacks any explicit 'when not to use' or named alternative sibling (e.g. compare_processes), so routing is good but not complete.

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