read_project_settings

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

The description declares the tool as read-only. However, with no annotations providing readOnlyHint, the description could be more explicit about side effects, error conditions, or dependencies (e.g., file existence). It is adequate but not comprehensive.

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?

The description is a single front-loaded sentence with no extraneous information. Every word adds value.

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?

Given the simplicity of the tool and the presence of many sibling tools, the description covers the core function. However, it could mention return type details or error handling. The lack of an output schema places some burden on the description, which is not fully addressed.

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 100% with one parameter. The description adds context that the file is 'project.godot' but does not elaborate on the path format or constraints. Baseline 3 is appropriate as the schema already defines the parameter.

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 clearly states the tool reads the project.godot file and outputs structured JSON. It is specific about the resource and output format, and distinguishes from sibling tools like modify_project_settings or get_project_info.

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?

The description does not provide explicit guidance on when to use this tool versus alternatives. It implies read-only access but lacks context about prerequisites or scenarios where other tools (e.g., modify_project_settings) would be appropriate.

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