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

Annotations are empty, so the description is the only behavioral disclosure. It adds the auth requirement 'Requires mcp:write scope' but doesn't describe return values, side effects, or failure modes. This is a minimal but non-empty disclosure.

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?

One concise sentence that states both operation and required scope. Every word earns its place; no redundant qualifiers.

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 schema handles parameter definitions, and the description states the essential operation, but the absence of an output schema and any mention of return behavior leaves a gap. For a simple create tool, the description is adequate but not fully complete.

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 covers all 5 parameters with inline descriptions (100% coverage). The description adds no parameter-level meaning, so baseline 3 is appropriate.

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 uses the specific verb 'Creates' with a clear resource ('new action item on a retrospective board'), immediately distinguishing it from sibling tools like update/list/complete. No ambiguity about the operation.

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?

It implies use for creating action items, but doesn't explicitly contrast with retro.actions.update or retro.actions.complete. The 'Requires mcp:write scope' is a permission prerequisite, not tool-selection guidance.

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