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

With no annotations provided, the description carries the full burden of behavioral disclosure. It fails to mention whether the test modifies game state, generates output files, requires a running scene, or has performance implications. The term 'stress test' implies intensity but lacks specifics on resource usage or side effects.

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 appropriately brief with two short fragments, avoiding verbosity. However, the '(Compatibility tool)' parenthetical adds minimal value without elaboration, and the extreme brevity constitutes under-specification rather than efficient information density.

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 has 2 parameters with 0% schema coverage, no annotations, and no output schema, the description is inadequate. It omits parameter semantics, behavioral constraints, and return value information necessary for safe and correct invocation.

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%, and the description provides no compensation. It does not explain what 'timeoutMs' controls (test duration? connection timeout?) or what 'autoConnect' connects to (the game? a test harness?). The parameters remain semantically undocumented.

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 states the tool runs a 'stress input test' and labels it as a 'Compatibility tool', providing basic verb and resource identification. However, it fails to distinguish from sibling test tools like 'run_test_scenario' or explain what 'compatibility' means in this context (backward compatibility vs. compatibility testing).

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 is provided on when to use this tool versus alternatives such as 'run_test_scenario', 'simulate_sequence', or 'assert_node_state'. The parenthetical '(Compatibility tool)' hints at a specific use case but lacks explicit 'when to use/when not to use' instructions.

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