Bootstrap Sandbox Guardrail

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

Annotations indicate write operation (readOnlyHint=false) and non-destructive (destructiveHint=false). Description adds important context about sandbox-only nature and no live settlement rails, which complements annotations without contradiction.

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 sentences directly state purpose and usage boundaries without any filler. Essential information is front-loaded in the first sentence.

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 the complexity (6 parameters), low schema coverage, and presence of an output schema, the description is incomplete. It fails to explain how parameters relate to the sandbox guardrail creation, which is needed for correct use.

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% and description provides no explanation of the 6 parameters (e.g., what 'operation' values are valid, how 'requested_spend_cents' is used). Parameter names alone are insufficient for correct invocation.

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?

Description explicitly states the tool creates a sandbox-only guardrail intent for testing, with clear differentiation from production tools. The verb 'bootstrap' and phrase 'sandbox-only guardrail intent' clearly define the resource and scope.

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?

Provides explicit when-to-use ('building or testing a first paid-tool integration') and when-not-to-use ('do not use for production live money movement or already-created Harbor intents'). Could be improved by naming specific alternative tools for production use.

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