fx_set_preset

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

No annotations provided. Description only states action without disclosing side effects, error behavior, or state changes. For a mutation tool (loading a preset), this is insufficient.

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?

Extremely concise: one-line action then three parameter descriptions. No extraneous information.

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?

Tool has 3 required parameters, no output schema, no annotations. Description omits return value, error states, and interaction with other fx tools. Incomplete for safe invocation.

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 0%, but description adds '0-based' for track_index and fx_index, which is helpful. However, no further detail on preset_name format or allowed values. Minimal extra beyond schema titles.

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?

Description explicitly states 'Load preset by name', with clear verb 'Load' and resource 'preset'. Differentiates from siblings like fx_get_preset and fx_navigate_preset.

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 on when to use this tool vs alternatives (e.g., fx_get_preset or fx_navigate_preset). No context about prerequisites or typical use cases.

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