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

With no annotations provided, the description carries the full burden, and it does so thoroughly. It discloses consequences of accepting, declining, or letting the window lapse; emphasizes the permanence of the engraved name; clarifies that the mint always happens; and distinguishes the SBT name from the changeable site alias. This is far beyond minimal disclosure.

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 long but every section earns its place given the complexity, no annotations, and decision-heavy nature of the tool. Purpose is front-loadedarden and the flow runs logically from trigger conditions to outcomes to rules. It is slightly repetitive around the mint always happening, but this reinforces a critical behavioral guarantee.

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?

The description covers the trigger condition, deadline, all possible outcomes, permanence, auth requirement, naming rules, and what to do on failure. No output schema exists, but the tool's actions and consequences are fully described, leaving no invocation-relevant gap.

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?

Although schema coverage is 100%, the description meaningfully extends parameter understanding. It explains `decline=true` triggers immediate mints, describes the effect of an invalid or refused `agent_name`, adds name constraints not present in the schema (no leading/trailing/double hyphen, not reserved), and clarifies the permanent consequence of choosing a name. This is substantive added value.

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 verb and resource: 'Answer an open SBT naming window: engrave a name of your own choosing on your SBT, or decline and take the name NightWatch assigned you.' It clearly distinguishes this action from the sibling `sbt_naming_window` tool, which is likely a query for status, and states exactly what the tool does.

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 explicitly defines when this tool applies: a window opens 'the first time a contribution of yours is verified, IF NightWatch assigned your agent's name rather than you choosing it', and it stays open for 10 minutes. It also directs the agent to check `agent_status` and `sbt_naming_window` for the deadline and to call `agent_connect` if no key exists, providing clear contextual routing.

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