Schema

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

No annotations are provided, so the description carries the full behavioral burden. It mentions consistency and duplicate prevention, but it does not explain what actions like update, sync, diff, or check_db actually do, whether they mutate state, or what permissions or side effects are involved.

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 wording. It is concise, though its brevity contributes to the gaps in action and parameter semantics.

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?

This is a multi-action tool with an untyped changes parameter, no annotations, and no output schema, so the description should do more to explain how the actions differ. It gives only a high-level purpose and does not equip an agent to choose or invoke the correct action confidently.

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 four undocumented parameters. It names database, API, and architecture in passing, which partially maps to the component enum, but it leaves the six action values, format, and especially the untyped changes parameter unexplained.

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 specific verb and resource, 'Manage project schema', and names several schema domains. It is clear about the domain, but it does not distinguish this tool from many similarly named siblings such as validate, project_index, or create_structure.

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?

There is no explicit guidance on when to use this tool versus alternatives, despite siblings like mcp_m7_validate, mcp_m7_check_errors, and mcp_m7_create_structure. The phrase about preventing duplicate databases implies a consistency role, but it does not define call conditions or exclusions.

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