save_blend

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

With no annotations and no output schema, the description carries the full behavioral burden, and it omits key traits: whether an existing file at this path is overwritten, whether missing parent directories are created, whether unsaved changes are flushed first, and whether the operation can fail or is idempotent. Only the mutation nature is implied by "Save".

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?

One short sentence with no filler, and the action is front-loaded. Its brevity is efficient rather than padded, though it leans toward under-specification rather than crispness.

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 write/mutation tool with zero annotations, no output schema, and an undescribed required parameter, the description does far too little — an agent cannot predict overwrite risk or the expected return. Sibling context doesn't fill the gap.

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 0%, so the single `path` parameter is undocumented in the schema. The description only implies that the path is a destination file by saying "as a .blend file"; it does not state whether the path is absolute or relative, whether the .blend extension is required or appended, or whether a directory is accepted.

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?

"Save a copy of the current scene as a .blend file" gives a specific verb (save) and resource (current scene → .blend file), which is enough to distinguish it from siblings like load_file or render_image. It stops short of explicitly contrasting with the closest sibling (load_file) or clarifying whether the document's own file path changes.

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 when-to-use guidance is offered: nothing says when to call this versus execute_blender_python (which could also write a .blend), or that a scene must exist / be loaded first. The agent must infer the preconditions from the name alone.

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