fmod_system_permission

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

No annotations are provided, and the description does not disclose behavioral traits such as idempotency, side effects (e.g., file permission changes), or required permissions. The input schema hints at read/write via omitting 'value', but the description does not confirm this.

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 short but confusing and poorly structured. It leads with a definition of an enumeration rather than the tool's action, which wastes the first sentence without adding value for tool selection.

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 tool has a single parameter with get/set behavior, the description does not explain what property is being accessed, what the return value is, or how the enumeration values are used. It is fundamentally incomplete for effective tool use.

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 description adds no meaning beyond the input schema. The schema already documents 'value' as optional for read vs write. The description's mention of 'Possible values are: [property · system.permission]' is vague and incomplete; it does not list actual enumeration options.

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 'An enumeration used with studio.system.File.setPermissions()' but fails to specify what the tool itself does. It is tautological with the tool name and does not describe the tool as a getter/setter of a permission property. No verb+resource is provided.

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 tool versus siblings like fmod_get_property or fmod_set_property. The description does not mention any context, prerequisites, or alternatives.

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