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

With no annotations provided, the description carries the full burden. It discloses key behavioral traits: idempotency ('same address replaces the existing watchpoint'), default values for parameters, and the tool's purpose. However, it doesn't mention potential side effects, error conditions, or performance implications.

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 perfectly structured: a clear purpose statement first, followed by behavioral note, then parameter details. Every sentence earns its place with no wasted words. It's appropriately sized for the tool's complexity.

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 annotations and no output schema, the description does well to explain parameters and idempotency. However, it doesn't describe what happens after adding a watchpoint (e.g., how breakpoints trigger, what data is returned). For a debugging tool with behavioral implications, this leaves some gaps.

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%, so the description must compensate fully. It successfully adds meaning for all 4 parameters: explains 'session_id' context, clarifies 'address' as a memory address, defines 'size' as bytes with default, and specifies 'access' options with defaults. This goes well beyond the bare schema.

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 specific action ('Add a memory watchpoint') and resource ('memory watchpoint'), distinguishing it from siblings like 'remove_watchpoint' or 'list_watchpoints'. It's not a tautology of the name and provides meaningful context about what the tool does.

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 usage by specifying idempotent behavior and default parameters, but does not explicitly state when to use this tool versus alternatives like 'add_breakpoint' or 'remove_watchpoint'. It provides some context but lacks explicit guidance on tool selection.

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