nexus_unblock_mods_from_earning_dp

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

Annotations already cover idempotency and non-destructiveness. The description adds the meaningful permission requirement and the return contract ('JSON {success} or an error string'), which go beyond the structured annotations. No contradiction with annotations exists.

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 compact and front-loaded: the action is stated first, followed by the key permission caveat and the return format. Every sentence earns its place without redundant elaboration.

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 single-optional-parameter mutation tool with annotations and an output schema, this description covers the essential context: what the tool does, the permission boundary, and the response shape. Nothing critical is missing.

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 describes `user_id` well ('User ID. Omit for the current user.'), so the baseline is strong. The description adds valuable parameter-related context by clarifying that targeting another user requires moderator permissions, which helps the agent decide whether and how to populate `user_id`.

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 opens with a specific action and target: 'Unblock a user's mods from earning Donation Points via v2 GraphQL.' This clearly distinguishes it from the sibling `nexus_block_mods_from_earning_dp` while also stating the exact resource and 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 a useful prerequisite ('Requires moderator permissions when targeting another user') and implies the tool is for reversing a block, but it never explicitly states when to prefer this tool over the sibling block tool or when not to use it. The usage context is mostly implied by the name and sibling list rather than spelled out.

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