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

Annotations are absent, so the description carries full burden. It lists the simulation's conceptual components but says nothing about actual tool behavior: whether it executes synchronously, returns transcripts, mutates state, requires a setup environment, or has side effects. This is thin for a tool with no safety annotations.

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?

A single concise sentence with no wordiness and the core idea front-loaded. However, it errs on the side of under-specification rather than being merely tight.

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 an output schema, the description leaves out critical operational context: parameter meanings, how the simulation is configured, what outputs are returned, and how this relates to other simulation tools. For a four-parameter tool with zero parameter documentation, this is incomplete.

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 coverage is 0% and the description does not mention any of the four parameters (game_type, num_rounds, agent_actions, opponent_policy). An agent gets no help understanding defaults, value ranges, or how they affect the simulation.

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 specific verb ('Simulate') and resource ('repeated multi-agent interaction') with distinctive features (social dilemmas, speech acts, reputation tracking). It clearly distinguishes itself from siblings like cognitive_create_simulated_environment and cognitive_step_simulated_environment by focusing on the simulation run rather than environment creation or stepping.

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 such as run_closed_loop_agent or simulate_actions. No conditions, prerequisites, or exclusions are provided, leaving the agent to infer suitability from the name and description alone.

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