ledfx_update_virtual_config

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

With no annotations, the description carries the full burden. It states 'Update' but does not disclose whether changes are immediate, affect active effects, or require specific permissions. No mention of side effects, error conditions, or result behavior.

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 sentence that front-loads the action and lists key capabilities. It is concise with no redundant words, though it could be slightly more structured with bullet points.

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 10 parameters and no output schema or annotations, the description is too succinct. It omits details about parameter interactions, default values, or the effect of updates on the virtual's state. The phrase 'and more' is vague and unhelpful.

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%, so baseline is 3. The description provides a high-level grouping of parameters (e.g., 'transitions', 'brightness'), but adds no new meaning beyond the schema's own parameter descriptions and enum values.

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 'Update virtual configuration' followed by specific aspects like transitions, brightness, frequency range, and matrix settings. This distinguishes it from sibling tools such as ledfx_activate_virtual (activation) or ledfx_update_virtual_segments (presumably segment-specific updates).

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 usage for modifying virtual properties but does not explicitly state when to use this tool over alternatives like ledfx_update_virtual_segments or ledfx_apply_global. No conditions or exclusions are provided.

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