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

With no annotations provided, the description carries full burden. It discloses the overwrite behavior ('Overwrites if the name already exists'), which is valuable for a mutation tool. However, it lacks information about permissions, side effects, error conditions, or what happens after association (e.g., persistence scope).

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 front-loaded with the core purpose, followed by behavioral note and parameter details. Every sentence earns its place with zero waste—no redundant or vague phrasing. The structure is logical and efficiently conveys essential information.

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?

For a mutation tool with no annotations and no output schema, the description is minimally adequate. It covers the basic operation and parameters but lacks details on return values, error handling, or integration with sibling tools (e.g., how symbols relate to breakpoints or memory operations). Given the debugging context, more behavioral context would be helpful.

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. It explicitly lists all three parameters with brief explanations ('session_id: The session ID', 'name: Symbol name', 'address: Memory address'), adding meaningful context beyond the bare schema. However, it doesn't specify format constraints (e.g., address integer range, name character limits).

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's purpose with a specific verb ('Associate') and resource ('symbolic name with a memory address'). It distinguishes from siblings like 'remove_symbol' by specifying creation/overwrite behavior rather than deletion.

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 provides no guidance on when to use this tool versus alternatives like 'list_symbols' or 'remove_symbol'. It mentions overwriting behavior but doesn't specify prerequisites, constraints, or typical use cases within the debugging context.

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