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

Annotations indicate readOnlyHint=false and destructiveHint=false, implying the operation is not read-only but not destructive either. The description says 'Bind' which implies a mutation but does not state the dynamic nature (e.g., whether it's reversible or requires agent creation). It does not contradict annotations, and adds some context about the relationship but not behavioral details like idempotency or error conditions.

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 one short sentence, which is concise and front-loaded. It is appropriately sized for a simple binding operation. No unnecessary words. The title and description are clear, but given the simplicity, it could be slightly expanded to include usage guidance without losing conciseness.

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?

With a simple 2-parameter operation, no output schema, and high schema coverage, the description is adequate but not complete. An agent might need to know if attaching an AI tool has prerequisites (e.g., the tool must exist) or side effects. Given the low complexity, this is acceptable but could be improved.

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 coverage is 100% and both parameters have descriptions. The description adds no additional meaning to the parameters beyond 'Bind'. The schema already documents that tool_id is an AI tool id and agent_id is the target agent's id. So the description does not add value; baseline 3 aligns with high schema coverage.

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 states a clear verb and resource ('Bind' and 'AI tool' to the agent). It does not differentiate from sibling tools like attach_sub_agent or attach_mcp_server, but the resource type is specific enough. A score of 3 is appropriate because it lacks explicit differentiation from similar attach tools, but purpose is evident.

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?

There is no explicit guidance on when to use this versus alternatives. However, the context is clear: it binds an AI tool to an agentanglophone. With many sibling attach tools, a description of when to choose this over attach_sub_agent would be valuable, but the purpose is implied by the name and description. This is minimal guidance.

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