Changes observed during successful MCP inspections.
v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Read page details' implies a read-only operation but doesn't specify what 'details' include, whether authentication is required, rate limits, error conditions, or how pages are identified. This leaves significant behavioral gaps for a tool with no structured safety hints.
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 extremely concise with just three words, front-loading the core action ('Read page details'). There's no wasted language or unnecessary elaboration, making it efficient for quick scanning.
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 complexity of sibling tools and lack of annotations or output schema, the description is insufficient. It doesn't explain what 'page details' entail, how pages are selected, or what the return format looks like. For a tool in a crowded namespace with no structured output documentation, more context is needed to be complete.
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 has 0 parameters with 100% schema description coverage, so the schema fully documents the absence of inputs. The description doesn't need to compensate for any parameter gaps, and it correctly implies no required inputs by not mentioning any. This meets the baseline for a parameterless tool.
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 'Read page details' is a tautology that restates the tool name 'page_details' with a generic verb. It doesn't specify what kind of page, what details are returned, or how this differs from sibling tools like 'page_id', 'page_posts', or 'page_events'. The purpose is vague and lacks differentiation.
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 alternatives. With many sibling tools like 'page_id', 'page_posts', and 'page_events' that might retrieve specific aspects of pages, there's no indication of what makes this tool distinct or when it should be preferred over others.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
