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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this is an update operation but doesn't explain whether this replaces the entire connections list or merges with existing ones, what permissions are required, whether changes are reversible, or what happens on success/failure. For a mutation tool with complex nested parameters, this is a significant gap in behavioral context.

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 brief with two sentences that get straight to the point without unnecessary elaboration. However, the second sentence could be more informative about what 'fields to update' means in context. Overall, it's efficiently structured but could benefit from slightly more substantive content.

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?

For a tool that updates complex fabric connections with nested objects, no annotations, and no output schema, the description is inadequate. It doesn't explain the mutation behavior, error conditions, relationship to sibling tools, or what constitutes a successful update. The agent lacks sufficient context to use this tool effectively in the broader fabric management system.

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 100%, so the schema already documents both parameters (fabricId and connections) thoroughly with detailed descriptions of all nested properties. The description adds no additional parameter semantics beyond what's in the schema, merely stating to 'pass the resource ID and the fields to update as arguments.' This meets the baseline for high schema coverage.

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 'Update the list of connections' which provides a basic verb+resource combination, but it's vague about what exactly is being updated (connections within a fabric) and doesn't distinguish this from sibling tools like fabricsAddFabricConnections or fabricsDeleteFabricConnections. The purpose is understandable but lacks specificity about scope and 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 like fabricsAddFabricConnections or fabricsDeleteFabricConnections. It only gives basic usage instructions ('pass the resource ID and the fields to update as arguments') without context about appropriate scenarios, prerequisites, or exclusions. This leaves the agent with insufficient context for tool selection.

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