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

The description adds useful behavioral detail beyond the annotations by disclosing the B20 no-op case and the legacy calldata return shape. With readOnlyHint=false and destructiveHint=false already covering the safety profile, this is helpful but still omits what the caller should do with the returned calldata or any auth requirements.

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?

Two compact clauses are front-loaded and each carries distinct, decision-relevant information. There is no filler or repetition.

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 one-parameter tool with no output schema, the description covers the key conditional outcomes and return payload for legacy programs plus the B20 no-op. It stops short of explaining how the returned calldata should be used, but it is complete enough for correct tool selection and invocation.

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?

The schema already fully documents the single token_address parameter at 100% coverage. The description does not add any parameter-level meaning, so the baseline score of 3 is appropriate.

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 specific conditional behavior: legacy ERC-20 programs return unpauseUtility and enableMinting calldata, while B20 programs are a no-op. This makes the activation purpose clear, though it does not explicitly distinguish the tool from siblings such as update_program_status or register_loyalty_program.

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?

It gives clear context by program type: use it for legacy ERC-20 activation and recognize that B20 programs are already active, making the call a no-op. It does not name alternative tools or explicitly state when to prefer them, so it falls short of full selection guidance.

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