save_blend

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

There are no annotations, so the description must carry the behavioral burden. It discloses that this is a save operation and adds a guardrail against unsolicited saves, but it does not explicitly state that the current file is overwritten on disk or note any irreversibility. The behavior is mostly inferable, but the side effect is not fully spelled out.

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 sentence that front-loads the action and then states the usage constraint, with no filler or redundancy. It is concise while conveying both what and when.

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 zero-parameter operation, the action and invocation condition are covered, and an output schema exists to document the return value. The only minor gap is the lack of explicit overwrite/destructive warning, which the absence of annotations makes more relevant.

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 tool has zero parameters, so the schema is complete and no parameter documentation could be expected. The description adds no parameter-specific meaning, but none is required; per baseline, a zero-parameter tool earns a 4.

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 the specific verb 'save' with a concrete resource, 'the current .blend', which exactly and unambiguously identifies the operation. It also distinguishes this tool from the sibling tools, none of which perform a file save.

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?

It provides an explicit call condition: 'call only after an explicit user save request.' This tells the agent when to invoke the tool and implicitly when not to, and no alternative save tool exists among the siblings, so no further routing is needed.

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