blender_pack_textures

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

The description discloses the core behavioral effect: loose images are packed into the .blend, making it self-contained. Since annotations only mark the tool as non-read-only, non-idempotent, and non-destructive, the description adds meaningful context about what actually happens.

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 two short sentences with no filler. The first sentence front-loads the action and outcome, and the second gives a concrete operational trigger. Every word 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?

For a simple two-parameter tool, the description covers the main purpose and usage context well. However, the undocumented 'repack' parameter is a meaningful gap, and there is no mention of what happens when the operation is run on a file that has no loose images or already packed textures.

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 description coverage is only 50%, and the tool description adds no parameter guidance. The 'repack' boolean has no schema description and is not mentioned at all, leaving an agent to guess when or why it should be set. Only 'response_format' is documented in the schema.

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 a specific verb and resource: 'Pack every loose image into the .blend.' It also clarifies the intended outcome ('so the file is self-contained'), which clearly distinguishes it from sibling tools like blender_load_image_texture or blender_bake_texture.

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 gives explicit usage timing: 'Do this before handing a .blend to someone else or committing it.' It does not mention alternatives or when not to use it, but the context is clear enough for an agent to decide.

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