Behavior2/5

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

With no annotations provided, the description carries the full burden. It only states the basic function and parameter hints but omits behavioral details such as error behavior, side effects, or preconditions (e.g., need for an active session). The presence of an output schema partially mitigates, but the description itself lacks depth.

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 concise: a single sentence capturing the core action, followed by clean metadata (command, source, category, args, link). No extraneous information, and the purpose is front-loaded.

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

Completeness5/5

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

For a simple symbol lookup tool, the description covers the essential aspects: purpose, parameters, and a reference link. Since an output schema exists, return value details are already provided externally. Everything needed to understand and invoke the tool is present.

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

Parameters4/5

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

Schema description coverage is 0%, but the description adds meaning to both parameters: 'session_id: The UUID of the session' and 'value: Address or value to look up symbols near.' This clarifies their purpose beyond the schema's bare types, aiding proper usage.

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 clearly states the tool's purpose: 'List the symbols nearest to the provided value.' It uses a specific verb ('list') and resource ('symbols nearest'), and implicitly distinguishes from sibling tools like pwndbg_telescope or pwndbg_search by focusing on symbol lookup rather than memory visualization or pattern search.

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

Usage Guidelines2/5

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

No explicit guidance on when to use this tool versus alternatives. The description does not mention scenarios, prerequisites, or contraindications. It simply states the function without context that would help an agent decide when to invoke it over similar tools.

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