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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Create' implies a write/mutation operation, but the description doesn't disclose any behavioral traits: no information about permissions needed, whether it's idempotent, what happens on duplicate reviews, error conditions, or what the tool returns. This is a significant gap for a mutation tool with zero annotation coverage.

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 extremely concise at just three words: 'Create a course review.' It's front-loaded with the core action and resource, with zero wasted words or unnecessary elaboration. This is appropriately sized for what it communicates.

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?

Given this is a mutation tool with 5 parameters, no annotations, and no output schema, the description is incomplete. It doesn't explain what happens after creation, what the tool returns, error handling, or behavioral constraints. The 100% schema coverage helps with parameters, but overall context for proper tool use is lacking.

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 all 5 parameters with their types, constraints, and basic descriptions. The description adds no additional parameter information beyond what's in the schema. According to the rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in the description.

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 'Create a course review' clearly states the action (create) and resource (course review), which is better than a tautology. However, it doesn't differentiate from sibling tools like 'create_user' or 'create_category' beyond the resource type, and it lacks specificity about what a 'course review' entails beyond the basic verb+noun.

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. There's no mention of prerequisites (e.g., user must be enrolled), when not to use it, or how it relates to sibling tools like 'get_course_review' or 'list_course_reviews'. It's a bare statement with no contextual usage information.

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