register_gem

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

No annotations are available, so the description must carry behavioral disclosure. It states the action but does not disclose side effects such as modifying project registration files, prerequisites, or reversibility, leaving the agent under-informed about the mutation's impact.

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 compact sentence plus two concise argument definitions; every part is functional. There is no redundant detail or filler.

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 simple two-string-parameter tool, the arguments are sufficiently documented and an output schema is present. However, because this is a mutation with no annotations and no mention of side effects or prerequisites, the behavioral context is incomplete.

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 input schema provides only parameter names and types with 0% description coverage. The description compensates by defining gem_path as 'Path to the gem directory' and project_path as 'Path to the project to add the gem to', making the relationship between both parameters clear.

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 names a specific verb ('Register'), a resource ('external gem'), and a destination ('O3DE project'), so it is clear what this tool does. This distinguishes it from sibling tools like create_gem, enable_gem, and list_gems, which operate on gems in different ways.

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 explicit guidance on when to choose this tool over alternatives or what conditions are required, such as whether the gem must already exist or whether the project must be active. The only guidance is the action itself, which is implied rather than stated.

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