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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only states that it initializes a new session, without clarifying side effects (e.g., whether it clears previous recordings), required prior state (e.g., a loaded page), or what happens on repeated calls. This minimal disclosure is insufficient for a tool that likely mutates state.

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 a single, clear sentence with no redundant words. It is front-loaded with the primary action. However, the conciseness comes at the cost of necessary detail, making it under-specified rather than efficiently packed.

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?

Despite having an output schema, the tool has 3 required parameters with no descriptions, no annotations, and no usage context. The description fails to explain how this tool fits into the broader recording workflow or what the parameters represent. This is a significant gap given the tool's complexity (multiple required params) and the many sibling tools.

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?

The schema has 0% description coverage, and the tool description does not mention any of the three parameters (flow_name, system_under_test, description). Since schema coverage is low, the description was expected to compensate by explaining parameter meanings or relationships, but it does not. This leaves the agent to infer semantics solely from parameter names.

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's function: initializing a new automated test case recording session. It uses a specific verb (initialize) and resource (recording session), which distinguishes it from sibling tools like export_session or execute_and_record.

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. It does not mention prerequisites, sequencing relative to other recording tools, or scenarios where this tool is preferred. There is no exclusionary or contextual information.

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