Behavior2/5

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

No annotations are provided, so the description must carry the behavioral disclosure burden. It mentions tracing and reporting a verdict but omits that the tool likely launches MAME, generates Lua scripts (indicated by the dryRun parameter), and does not explain what the 'status verdict' actually is. Side effects and outcome are opaque.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no filler and is front-loaded with the tool's focus. It efficiently conveys the scope and purpose without redundant information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 10 parameters, no output schema, and no annotations, this one-sentence description is under-specified. It lacks information about the execution lifecycle, expected return value format, error behavior, and prerequisites, making it inadequate for autonomous invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds no parameter-specific semantics beyond the generic harness context; it does not explain how parameters like injectPreset or frames relate to the C-Chip tracing.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description defines a specific verb ('trace') and a precise resource ('C-Chip accesses' in the $900000-$900FFF range) and adds a report action on the $900803 status. The 'Superman helper' qualifier distinguishes it from generic sibling tools like trace_memory_access.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'Superman helper' implies the tool is for Superman game debugging, giving some context. However, it does not explicitly state when to use this tool over alternatives like trace_memory_access or run_lua_script, so the usage guidance is only implied.

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