resolve_pointer_chain

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the 'bounded' constraint (matching maxItems) and implies sequential pointer dereferencing, but it does not disclose potential failure modes (e.g., invalid addresses), whether memory is actually read at each step, or the exact return value. This is partial disclosure beyond annotations.

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, front-loaded sentence that directly states the tool's purpose without extraneous words. Every word contributes value, making it highly concise and well-structured.

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 the moderate complexity (two params, no output schema) the description is minimal but not entirely inadequate. It lacks critical context such as the expected return value (resolved address), when to use the tool vs alternatives, and possible failure conditions. It is complete for a very narrow definition but leaves gaps for an agent invoking it correctly.

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?

While schema coverage is only 50% (baseAddress has a description but offsets does not), the description compensates by clarifying that offsets are 'pointer offsets' and forming a 'bounded sequence'. This adds meaningful semantics beyond the raw schema for the offsets parameter, which otherwise lacks any description.

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 a specific verb ('Resolve') and resource ('base address plus a bounded sequence of pointer offsets'), which is a distinct operation from sibling tools like read_memory or dump_memory. It unambiguously identifies the tool's core function.

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, nor are any exclusions or prerequisites mentioned. The description simply defines the operation without contextualizing its use relative to memory reading or scanning tools.

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