code-explainer

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

The description lacks any behavioral context such as whether the tool reads or modifies code, requires authentication, or has side effects. With no annotations, this omission is critical for safe usage.

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 concise sentence, but it omits essential details such as input method, output format, and usage examples. While brief, it is not adequately informative.

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 no parameters, no output schema, and minimal description, the tool definition is severely incomplete for an agent to use correctly. The description does not specify what the tool does exactly (e.g., returns a report, updates code, etc.) or how to invoke it.

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?

Despite having zero parameters, the description does not explain how the agent should provide code for exploration. The input schema is empty, implying input may come from context, but this is not clarified, leaving ambiguity in invocation.

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 helps novice programmers understand code and analyze tech stack and best practices. It is specific on the target audience and function, but does not differentiate from sibling tools like gen_prd_prototype_html or typescript-challenge-analyzer, leaving some ambiguity about when to use this one.

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. There is no mention of prerequisites, context, or conditions that would help an agent decide whether to invoke code-explainer over other tools.

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