create_session

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

With no annotations, the description must disclose behavioral traits but only says 'Create a new session (event).' It does not mention side effects, default values, authentication needs, or whether the session is immediately available. The brevity leaves the agent guessing.

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 (one sentence), but it is under-specified to the point of being unhelpful. Proper conciseness should include essential usage context, not just a tautology of the tool name.

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 the tool's complexity (16 parameters, nested objects, no output schema, no annotations), the description is completely inadequate. An agent has no guidance on parameter semantics, required fields beyond schema, or expected behavior.

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 0%, meaning no parameter descriptions in the schema. The tool description adds no meaning beyond the property definitions (e.g., slug pattern, multilingual objects, status enum). For a tool with 16 parameters and nested objects, this is critically insufficient.

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 verb 'create' and resource 'session', with parenthetical 'event' to clarify context. It effectively distinguishes from sibling tools like create_solution or create_story, though it could be more specific about what a session entails.

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?

No guidance on when to use this tool versus alternatives like update_session (for existing sessions). Lacks prerequisites, when-not to use, or context for creation (e.g., required fields, default status).

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