get_ms_copilot_topics

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

The annotations already declare readOnlyHint=true and openWorldHint=true, so the description doesn't contradict them. The description adds the useful clarification that the mapping is configured in Copilot Studio on the Microsoft side, which helps set expectations about what the tool can and cannot do. With good annotations present, this is adequate but not exceptional.

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?

Two concise sentences, front-loaded with the primary purpose and followed by an important caveat. The second sentence about Copilot Studio configuration earns its place by setting expectations and preventing the agent from incorrectly expecting mapping configuration to be exposed via the API. No wasted words.

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 simple single-parameter read-only listing tool with readOnlyHint and openWorldHint annotations and 100% schema coverage, the description is largely complete. It covers purpose, scope, and an important architectural caveat. Given the tool's simplicity, there's little else it could meaningfully add. The output schema absence is acceptable for a straightforward list 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?

Schema coverage is 100% and there's only one optional parameter (limit). A single optional limit parameter with clear default documentation is straightforward; the description doesn't repeat what's in the schema. Description appropriately doesn't waste space explaining parameters that are already fully documented.

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 states the tool lists Virtual Agent topics (sys_cs_topic) that back a Microsoft Copilot integration, with a specific verb (List) and resource. It distinguishes from the sibling get_virtual_agent_topics by scoping to MS Copilot specifically, though it doesn't explicitly name the sibling. The second sentence usefully clarifies that topic mapping is configured on the Microsoft side.

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 context that this is for Microsoft Copilot integrations and implies it's a read-only listing tool. However, it doesn't explicitly state when to prefer this over get_virtual_agent_topics or other listing tools, nor does it give when-not-to-use guidance. The note about Copilot mapping being external is helpful context but not usage guidance per se.

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