get_registry_entity

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

No annotations are provided, so the description carries full behavioral burden. 'Get' implies a safe read, but nothing is said about permission requirements, error behavior for an unknown entity_id, or what 'full registry details' actually includes.

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 short sentence, front-loaded with the verb and resource, with no wasted words. Brevity here reflects terseness rather than padding, though it borders on under-specification.

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 no output schema, no annotations, and 0% parameter coverage, the description should at minimum sketch what registry fields are returned and how the id is sourced. It leaves both gaps open for a tool whose only job is to return that data.

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 description coverage is 0% for the single entity_id parameter, so the description must compensate and does not — it never explains the expected id format or where an agent obtains a valid one. It only restates that the id identifies one entity.

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 (Get), resource (registry entity), and scope (full details for a single entity_id). The word 'single' implicitly contrasts with the sibling list_registry_entities, but no sibling is named explicitly, so the differentiation is only implied.

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?

No guidance on when to use this versus list_registry_entities, get_device, or update_registry_entity. The agent must infer that this is the fetch-one-by-id counterpart to the list tool.

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