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

No annotations provided, so description carries full burden. Fails to disclose message limits (how many returned), time range (recent vs all), pagination behavior, or whether this is a destructive vs safe operation. Lacks critical behavioral context for a data retrieval tool.

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?

Extremely concise single sentence with zero redundancy. Appropriate length for a simple zero-parameter read operation, front-loaded with the essential action and resource.

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?

Covers the basic purpose but leaves significant gaps given no output schema or annotations. Missing: return format (message structure), volume limits, and whether channel context is inferred from session or hardcoded. Adequate but minimal for agent decision-making.

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?

Input schema has zero parameters (empty properties object). With no parameters to document, the baseline score of 4 applies. Description does not need to compensate for missing schema documentation.

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?

States a clear verb ('Read') and resource ('messages from a Teams channel'). Specifies 'channel' which helps distinguish from sibling tool 'teams_read_chat_messages', though it doesn't explicitly clarify the difference between channels vs chats for agents unfamiliar with Teams terminology.

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?

Provides no guidance on when to use this versus 'teams_read_chat_messages' or prerequisites like needing channel IDs from 'teams_list_channels' first. No mention of required permissions or authentication context.

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