pixelblaze_set_active_pattern

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

No annotations are provided, so the description must convey behavioral traits. It indicates a mutation (switch) and returns confirmation, but lacks details on side effects, permissions, latency, or whether the change is instantaneous. The minimal disclosure limits transparency beyond the obvious action.

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 brief, with a clear purpose statement followed by compact parameter documentation. Every sentence serves a purpose: stating the action, explaining the parameter, and indicating the return value. No extraneous content.

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?

While the tool is simple (one parameter, mutation), the description lacks details about preconditions (e.g., device must be connected) or consequences (e.g., stops previous pattern). The existence of an output schema (not shown) may supplement, but the description alone feels adequate but minimal for a mutation tool with no annotations.

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 input schema has no description for 'pattern_id' (0% coverage), but the tool description adds: 'pattern_id: The pattern ID to activate (from pixelblaze_list_patterns).' This explains the parameter's meaning and source, providing clear semantic value beyond the schema alone. Could be enhanced with format or constraints.

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 states 'Switch the PixelBlaze to run a specific pattern by its ID,' clearly identifying the action (switch/run), resource (pattern), and selection mechanism (by ID). This distinguishes it from siblings like pixelblaze_get_active_pattern (read) and pixelblaze_list_patterns (list).

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 mentions 'from pixelblaze_list_patterns' for pattern_id, implying a prerequisite step, but does not explicitly state when to use this tool versus alternatives (e.g., get vs set) or provide exclusions. The guidance is implied rather than explicit.

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