Lazy MCP and skill capability hub

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

The description adds meaningful trust and scope context beyond the annotations: only trusted MCPs should be requested, and third-party proposals require human approval outside this MCP. However, it does not disclose what actions such as enable, disable, configure, or reload do to the catalog state, and the annotation shadow has readOnlyHint=false so mutation is implied. It does not contradict the annotations.

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 compact and well structured: an operational overview, a simple workflow rule, and a clear trust boundary. Every sentence contributes useful decision-making information. It avoids wasted words and front-loads the most important action: search.

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?

The description explains the main workflow and the important human-approval boundary, but the tool exposes many actions - configure, status, disable, proposals, catalog.reload, skill.load - and not all of them are explicitly characterized. Since there is no output schema and no sibling tool list, the agent must rely heavily on design wish for some branches. It is workable but not fully complete for such a complex dispatch tool.

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 covers all parameters with detailed descriptions, so the description does not need to restate them; the 100% schema coverage sets the baseline at 3. The only additional guidance, “avoid includeSchema unless necessary”, reinforces the schema's hint but adds no new meaning to the overall parameter set. The description is sufficient thanks to the schema, not beyond it.

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 identifies the tool as a multi-action hub: search/inspect a catalog, enable a trusted MCP, list tools, proxy a tool call, and load a skill body. It names a specific resource and the operations supported, making the dispatching nature obvious. There are no sibling tools to differentiate from, so the lack of explicit sibling contrast is not a major gap.

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 gives practical direction: “Start with search; avoid includeSchema unless necessary” and warns that third-party proposals require human approval outside this MCP. This tells the agent how to begin and when the proposal flow is not self-contained. It lacks explicit comparison to sibling tools because none exist, but it does not fully clarify when to choose configure/status/disable over the primary path.

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