Changes observed during successful MCP inspections.
v0.3.1Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already disclose that this is a non-read-only, idempotent, and non-destructive operation. The description adds the target device ('Denon') but doesn't discuss side effects, prerequisites, or error conditions, though for a simple mute activation this is acceptable given annotation coverage.
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, compact sentence that immediately conveys the action and target. There is no superfluous information, achieving excellent conciseness.
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's simplicity—no parameters, no output schema, and straightforward action—the description provides adequate context by identifying the device and the operation. It doesn't reference related tools, but that is not strictly necessary for a basic mute-on command.
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 tool takes zero parameters, and the schema coverage is 100% (an empty schema). The description doesn't need to elaborate on parameters, and it correctly implies the mute operation applies to the Denon device, satisfying the baseline for parameterless tools.
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 a specific action ('activate the mute') and identifies the target device ('Denon'). This verb-resource pairing distinguishes it from sibling tools like mute_off and mute_toggle, making the tool's purpose unambiguous.
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 provides no guidance on when to use this tool versus its siblings, such as mute_off or mute_toggle. It does not mention scenarios where one might prefer one mute control over another, leaving the agent to infer usage from the tool name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
