sentinel_stablecoins

Monitor stablecoin pegs (USDC, USDT, DAI) across blockchain networks to detect depegs and deviations from target values.

Instructions

Monitor stablecoin pegs (USDC, USDT, DAI) across all chains. Detects depegs and deviations.

No arguments

Behavior3/5

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

With no annotations provided, the description carries full burden. It discloses scope ('across all chains') and detection targets ('depegs and deviations'), but omits whether this triggers alerts, requires subscriptions, returns current state vs historical data, or has side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two efficient sentences with zero waste. First sentence establishes scope and coverage, second specifies detection behavior. Well front-loaded and appropriately sized.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, and the description omits what the monitoring returns (current prices? deviation percentages? alerts?). For a zero-parameter monitoring tool, the description suffices for selection but leaves operational gaps regarding return values.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Zero parameters present, establishing baseline 4. The description implicitly confirms no filtering parameters are needed (covers 'all chains'), matching the empty schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clear specific verb ('Monitor') and resource ('stablecoin pegs USDC/USDT/DAI across all chains'). However, it does not explicitly differentiate from sibling tools like sentinel_scan or sentinel_chain despite their similar naming patterns, leaving potential ambiguity about overlap.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the specificity of the resource (stablecoins vs general monitoring), but there is no explicit guidance on when to prefer this over sentinel_scan, sentinel_compare, or other siblings, nor any prerequisites stated.

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