Project overview

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds the content inventory, but says nothing about behavior when projectPath is invalid, whether the listed scenes/scripts are truncated, or performance on large projects, which is the remaining useful ground.

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?

Two sentences, zero filler, with the resource and its contents front-loaded and the usage hint placed last. Every clause earns its place.

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, the description correctly takes on the burden of describing the return payload and does so field by field. The only gap is that it does not signal whether the scene/script lists are bounded or paged.

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?

There is only one optional parameter and schema description coverage is 100%, including the default-project fallback, so the schema carries the load. The description does not mention projectPath at all, adding nothing beyond the structured field.

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 ('Overview') and resource ('a Godot project') and enumerates exactly what is covered (name, main scene, renderer, autoloads, plugins, scenes/scripts). It is clearly broader than siblings like get_godot_version or get_scene_tree, but it never names those siblings to force the distinction.

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?

'A good first call' gives explicit positive usage context — an agent knows to reach for this during project discovery. There is no when-not guidance or named alternative, so it stops short of full routing instructions.

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