Changes observed during successful MCP inspections.
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 says the tool 'emits' output, implying a read-only or generative operation, but does not disclose whether it writes to disk, returns a string, requires a valid theme name, or has side effects. For a tool with no annotations and an output schema, description adds little beyond naming output formats.
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 with no wasted words. It is appropriately concise, though it may be too terse given the lack of parameter and usage details.
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 no annotations, 0% schema coverage, 2 parameters, and many overlapping sibling tools, the description is insufficient. It omits parameter semantics, usage context, and behavioral details. The presence of an output schema alleviates the need to describe return values, but other gaps remain significant.
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 description coverage is 0%, so the description must compensate for both parameters. It indirectly refers to 'name' and the format choice, but does not explain what values 'name' accepts, whether it must match an existing theme, or what valid 'fmt' values are. Since an output schema exists, return value explanation is unnecessary, but parameter meaning is left undocumented.
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 a verb and resource: 'Emit a named theme as CSS custom properties (or full JSON).' This is clear about what it does. However, it doesn't distinguish itself from sibling tools like palette_themes_impl or palette_export_impl, which likely overlap in theme output. Without that differentiation, the purpose is adequate but ambiguous in the sibling context.
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 is provided on when to use this tool versus alternatives such as palette_export_impl or palette_themes_impl. It mentions output formats but does not state when one should choose CSS over JSON or why this tool is preferable to siblings. Neither conditions nor exclusions are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
