render_load_preset

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

No annotations are provided, so the description carries the full burden. It discloses that the tool applies the preset's settings, implying a state-changing operation. However, it does not mention whether current settings are overwritten, behavior on invalid names, or any return value, though the presence of an output schema reduces the need for return details.

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, front-loaded sentence that states the action and result with no wasted words. Every clause earns its place.

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?

The tool is simple (one parameter, well-documented schema, output schema exists). The description fully conveys the primary action. It lacks only an explicit statement about side effects or prerequisites in the main description, but the schema covers the prerequisite.

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 coverage is 100% with a helpful parameter description ('Exact name of the preset. Get valid names from render_get_presets()'). The main tool description adds no parameter-level information, so the baseline of 3 applies.

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 a specific verb 'Load' with a clear resource 'render preset' and mechanism 'by name, applying its settings'. It distinguishes itself from sibling tools like render_get_presets (which lists presets) and render_set_settings (which sets individual settings).

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 main description implies usage (when you want to load a preset), and the schema for preset_name explicitly directs the agent to render_get_presets() for valid names, providing a clear prerequisite. However, it does not explicitly discuss alternatives or exclusions, such as when to use render_set_settings instead.

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