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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the tool uses 'Keystone' but doesn't describe what happens after assembly (e.g., where the machine code is stored, if it's executed, or if errors are returned). For a tool that transforms code, this lack of output or error behavior details is a significant gap.

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 well-structured and front-loaded with the core purpose, followed by parameter details. Every sentence adds value, with no redundant information. It could be slightly more concise by integrating the parameter explanations more seamlessly, but it's highly efficient overall.

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 is incomplete for a tool that performs code transformation. It explains inputs well but omits critical details about outputs (e.g., machine code format, error handling) and behavioral context (e.g., how this integrates with sibling tools like emulation). This leaves gaps for an agent to use it effectively.

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 effectively explains all three parameters: 'arch' with architecture examples, 'code' with assembly source examples, and 'address' with its effect on relative offsets. This adds substantial meaning beyond the bare schema, though it could specify format constraints (e.g., integer base for address).

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: 'Assemble instructions into machine code using Keystone.' It specifies the verb ('assemble'), resource ('instructions'), and technology ('Keystone'), distinguishing it from sibling tools like 'disassemble' which performs the inverse operation.

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. While it mentions 'Keystone,' it doesn't explain when assembly is needed in the context of sibling tools like emulation or memory operations, leaving the agent to infer usage from the tool name alone.

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