imgui_unload_texture

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

No annotations are provided, so the description carries the full burden. It does disclose the destructive nature ('unload', 'free its GPU resources'), which is useful. However, it doesn't specify what happens on invalid IDs, whether errors are raised or silently ignored, or any associated state changes beyond GPU resource freeing. For a resource-management tool, some error/edge-case disclosure would be valuable.

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?

A single, tight sentence that states both the operation and its effect. Zero wasted words. No redundancy with the schema or annotations.

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?

This is a simple tool with one parameter, fully documented schema, and no output schema required. The description covers the core purpose adequately. However, given it's a destructive operation with no annotations, some additional guidance on behavior with invalid/duplicate IDs or whether the id is reusable could improve completeness. Still, for the tool's simplicity, it is near-minimally-viable but not fully complete on edge cases.

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 single parameter 'id' already has a schema description ('Texture identifier to unload') with 100% coverage, so the schema carries the load. The tool description references 'a previously loaded texture' which implies the id must correspond to a loaded texture, adding slight value beyond the schema. Baseline 3 is appropriate since schema fully documents the parameter and description adds minimal extra meaning.

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 uses a specific verb+resource pair ('Unload a previously loaded texture') and clearly states the action of freeing GPU resources. It naturally pairs with the sibling imgui_load_texture in the sibling list, making the purpose distinguishable.

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 implies the tool should be called after a texture has been loaded via imgui_load_texture (the sibling tool), establishing clear context. However, it doesn't explicitly state when not to use it, prerequisites (e.g., texture must exist), or what happens when unloading an already-unloaded or nonexistent texture.

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