initialize_data_registry

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

Annotations declare destructive=true, readOnly=false, and idempotent=false. The description adds genuine mechanism beyond that: it names the subsystem call, says the registry's sources become live, and notes that precached DataTable sources are cached for synchronous gets. It does not spell out what existing state is overwritten, but it adds real behavioral context and does not contradict the annotations.

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?

Front-loaded with the action, followed by mechanism and return keys. There is little waste, and the return block is useful because no output schema exists. Slightly heavier than necessary, but well structured.

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 one-parameter mutation tool with annotations but no output schema, the description supplies the return shape and internal mechanism, which are important. However, it omits when-not-to-use and gives no routing against sibling registry tools, leaving a meaningful gap for an agent choosing between them.

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 100% for the single registry_path parameter, which is already documented as the content path to the UDataRegistry asset. The description adds no syntax, format, or path semantics beyond the schema; it only echoes registry_path in the return shape, so baseline 3 applies.

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+resource: load, register, and initialize a UDataRegistry, and names the underlying call UDataRegistrySubsystem::LoadRegistryPath. It does not explicitly position itself against close siblings like create_data_registry or refresh_data_registry_map, so it stops short of a 5.

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 when-to-use, when-not-to-use, or alternative guidance is provided. With siblings such as create_data_registry, refresh_data_registry_map, and list_data_registry_sources, the agent gets no routing help beyond the verb itself.

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