explain_reverse_stage

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

The annotation readOnlyHint=true already covers the safety profile. The description adds the content sections of the explanation, which is useful context. However, it does not disclose behavior beyond that, such as how includeDocs affects the output or any response format details. With annotations covering the main concern, a 3 is appropriate.

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, front-loaded sentence that lists the tool's output components without waste. It is appropriately brief for a simple read-only tool, though it could have added parameter guidance without becoming bloated.

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?

With no output schema, sparse annotations, and zero parameter descriptions, the tool remains under-specified. The description outlines the explanation content but fails to clarify the input parameters (especially includeDocs) or what the response looks like, leaving the agent guessing on invocation details.

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 explain either parameter. The term 'stage' is mentioned, giving some hint about the primary parameter, but 'includeDocs' is entirely unexplained. The description does not compensate for the lack of schema descriptions, leaving parameter meaning ambiguous.

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 a specific verb ('Explain') and resource ('reverse-engineering stage') with detailed content ('goals, entry criteria, avoid list, and recommended tools'). This clearly distinguishes it from siblings like 'recommend_next_step' by focusing on stage explanation rather than next-step suggestions.

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 implies clear usage context: use this tool when you need to understand a reverse-engineering stage's details. It does not explicitly mention alternatives or when not to use, but the purpose is unmistakeable.

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