metashunt_set_trigger

Configure or replace a trigger that watches the live current stream and fires when readings cross above or below a set mA threshold.

Instructions

Add/replace a host-side trigger watching the live stream for a crossing above above_ma and/or below below_ma (mA).

B3.2/5.0
Behavior2/5

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

No annotations are provided, so the description itself must disclose behavior. It states 'Add/replace' but does not explain side effects, such as whether an existing trigger with the same name is overwritten, whether the trigger starts immediately, or what happens on invalid threshold combinations.

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?

The description is a single concise sentence that packs the essential purpose and threshold semantics without unnecessary words or repetition.

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?

The description gives enough to understand the core operation, but lacks important context such as parameter meanings for 'name', threshold validation rules, return behavior, and side effects. It is adequate but not fully complete for an agent to use confidently.

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

Parameters2/5

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

Schema coverage is 0% and the description only partially clarifies above_ma and below_ma as threshold values in mA. The required 'name' parameter is not described at all, and the exact semantics of 'and/or' and whether at least one threshold must be provided remain ambiguous.

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

Purpose5/5

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

The description clearly states a specific action ('Add/replace') and resource ('host-side trigger'), and defines the trigger condition as crossing above and/or below the given mA thresholds. It is easily distinguished from sibling tools like list_triggers and remove_trigger.

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

Usage Guidelines2/5

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

The description does not explicitly explain when to use this tool versus alternatives, such as metashunt_list_triggers or metashunt_remove_trigger. There is no guidance on conditions for creating versus replacing an existing trigger or when another tool would be more appropriate.

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