save_model

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

With no annotations provided, the description carries the full behavioral burden. It does disclose one genuinely non-obvious trait — an empty path targets the current file and fails if the model was never saved — but says nothing about overwriting existing files, permissions, path validation, or atomicity for what is a write/save operation.

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?

Two short sentences, front-loaded with the action, followed by a compact arg description. The 'Args:' block is slightly redundant with the single-parameter schema but adds the format detail, so little is wasted.

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?

An output schema exists, so return values need no explanation, and the single parameter is fully covered including its default behavior. The remaining gap is the absence of any annotation-equivalent safety detail for a save operation.

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 description must compensate, and it largely does: it specifies a full Windows path, the .bdb extension, and the exact semantics of the empty default (save to current file). It stops short of stating directory-existence or overwrite requirements.

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?

States a specific verb and resource ('Save the open model'), which is immediately distinguishable from siblings like open_model, new_model, and edit_table. It does not explicitly position itself against those siblings, but the action is unambiguous.

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?

Usage is implied rather than stated: it operates on the currently open model, so an agent can infer it applies after open_model/new_model. There is no explicit when-to-use/when-not guidance or named alternative, though the empty-path failure condition gives some operational context.

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