get_render_settings

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 burden. 'Current render settings' implies a read-only state query, but the description doesn't explicitly state that nothing is modified, nor does it describe the response shape or failure conditions. This is acceptable for a simple getter but leaves assumptions implicit.

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 compact fragment that contains exactly the information an agent needs for a no-argument getter. It is front-loaded and contains no filler.

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 no-parameter getter, the description is nearly complete: it states the subject (render settings) and the fields returned. It would be slightly stronger with an explicit return-format note, but the tool is simple enough that the missing output schema is not a major 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?

The tool has zero parameters, so there are no parameter semantics to document. The description's enumerated fields (engine, resolution, samples, output format) serve as useful context for what the returned data will contain, which is all that is needed here.

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 identifies the tool as exposing current render engine, resolution, samples, and output format; the 'get' in the name makes the retrieval intent clear. It is specific enough to be distinguished from set_render_settings, though it never uses an explicit verb like 'returns'.

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 given about when to call this versus alternatives such as set_render_settings, render_preview, or get_workspace_info. The only hint is the word 'Current', which implies a read operation, but no explicit exclusions or sibling references are provided.

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