preview_specification_autofill

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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Safe preview' weakly suggests non-destructiveness, but it does not state whether the tool modifies anything, whether it requires an open document, what side effects it may trigger, or what the preview result looks like. The safety claim is too vague to be actionable.

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 a single concise sentence with no filler or repetition. It loses a point because the phrasing is somewhat awkward and telegraphic, but overall it is efficiently sized.

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?

This is a seven-parameter tool with zero schema coverage, no annotations, and no output schema, so the description needed to provide substantial context. It only gives a high-level preview notion and leaves out parameter semantics, return value, safety guarantees, and relation to the many sibling tools. It is far from complete.

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 for seven undocumented parameters. It does not explain `fields`, `fill_only`, `document_id`, `layout_name`, `max_objects`, `include_root`, or `description_index`. An agent has no semantic grounding for any parameter.

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 names a specific verb ('preview'), a resource ('specification autofill'), and the data source ('model tree'), which is enough to distinguish it from the sibling `apply_specification_autofill`. However, 'filling or syncing' is somewhat ambiguous about what the preview actually shows or computes.

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 phrase 'safe preview' implies that this should be used before applying changes, but it never explicitly says when to use this tool versus `apply_specification_autofill` or `refresh_specification_from_model`. No exclusions, prerequisites, or alternatives are named.

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