set_render_settings

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

With no annotations provided, the description must disclose behavioral traits. It only says 'Configure,' which implies mutation, but fails to clarify if changes are applied immediately, require a restart, or have side effects. No mention of permissions, validation, or error conditions.

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 concise: a single introductory sentence followed by a bulleted list of parameters. It is front-loaded with the purpose, and each line contributes useful information. Minor redundancy (e.g., 'Format string' could be omitted) but overall efficient.

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?

Given the tool has 3 optional parameters and an output schema (not described), the description covers most essential details for basic use. However, it lacks information on default behaviors, interaction between parameters (e.g., must render_format and codec be set together?), and what the tool returns or how it affects the project state.

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 schema has 0% description coverage, so the description compensates by listing common keys for 'settings' and examples for 'render_format' and 'codec'. This adds significant meaning beyond the schema's minimal titles, though it doesn't explain all possible parameters or their exact formats.

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 the tool's purpose: 'Configure render settings for the current project.' It uses a specific verb ('Configure') and resource ('render settings'), and distinguishes from siblings like 'get_render_settings' and 'start_rendering' by focusing on the configuration step.

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 description implies that this tool is used before rendering to set parameters, but it does not explicitly state when to use it versus alternatives. No guidance on prerequisites, exclusions, or scenarios where other tools (e.g., 'set_project_info') might be more appropriate.

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