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

With no annotations, the description must carry the full behavioral burden. 'Returns ...' discloses that this is a read-only lookup, which is useful, but it says nothing about what happens with an unknown or invalid process_id, whether results are cached/static, or any auth or rate constraints. Adequate but thin 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?

Two sentences: the first front-loads the usage trigger with examples, the second enumerates return fields. No filler or repetition, though the field list is somewhat list-like and could be trimmed to reference the output structure.

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?

Since no output schema exists, enumerating the returned fields is genuinely necessary and done well. The remaining gap is the process_id input semantics, which is the one thing an agent must get right to invoke the tool successfully.

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 schema has 0% description coverage and the description never mentions process_id at all — it doesn't say what identifier format is expected, whether it is a slug or enum-like value, or how to discover valid values. The only parameter that gates a correct call is completely undocumented in both schema and prose.

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 states a clear retrieval action and enumerates the exact fields returned (category, build size, tolerance, compatible materials, lead time, surface finish), which distinguishes it from siblings like get_equipment_qc_specs or get_material_compliance. It lacks a crisp opening verb+resource phrase, but the intent is unambiguous.

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?

It gives explicit trigger conditions with three concrete user-question examples ('what is the tolerance of SLS?', 'build volume of FDM?', 'lead time for CNC machining?'), which is strong context. However, it never names an alternative tool (e.g., compare_processes or find_alternative_processes) or states when NOT to use it, so routing among siblings remains partly inferential.

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