blender_file_save

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

Annotations already indicate readOnlyHint=false and destructiveHint=false, so the description could add value by clarifying that saving overwrites the file and that the default compression is true. It does not mention behavior when filepath is null or the return value contents. Contradictions: none.

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 very short and uses an Args/Returns structure, which is good. However, it is under-specified; conciseness is not valuable if it omits essential information.

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 tool with one param (nested) and no output schema shown, the description is incomplete. It does not explain what 'Save result' means or whether the tool returns a path or status. With annotations providing idempotent hint, the description still lacks details about the save behavior and error conditions.

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% per context, but the schema itself has descriptions for compress and filepath. The description's 'File path and compression options' is vague and does not explain that filepath defaults to null meaning 'use current file' or that compress defaults to true. It adds minimal meaning beyond 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 clearly states 'Save the Blender file,' which is a specific verb+resource action. This distinguishes it from sibling tools like blender_file_open (open) and export tools (export to formats). However, it could be more precise about whether it saves to the current file path or prompts for a new location.

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 is provided on when to use this tool versus alternatives like blender_export_fbx or blender_file_open. The description gives no context for when not to use it or what prerequisites exist (e.g., file must be open).

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