np_query_triggers

Retrieve trigger signals sent to an organoid over a configurable time window, with optional deduplication of repeated up transitions.

Behavior2/5

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

With no annotations provided, the description carries the full burden, but it only states the query purpose. It does not explicitly confirm read-only behavior, side effects, or any limitations beyond the schema's parameter details.

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

Conciseness4/5

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

The description is brief and front-loaded, fitting in one sentence. However, the 'TriggersQuery' prefix is redundant with the tool name, wasting a few words, though the rest is concise.

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 tool is simple with two well-documented parameters and no output schema, so the description is nearly adequate. However, it doesn't describe the return format, error behavior, or how it relates to sibling trigger/spike tools.

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

Parameters3/5

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

Schema coverage is 100% for both parameters, so the baseline is 3. The description adds no additional parameter context, but the schema already fully documents each parameter's meaning, so no gap exists.

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?

The description identifies the resource (triggers sent to the organoid) and the operation (query over a window), clearly distinguishing it from sibling spike-related tools. However, it lacks an explicit verb like 'retrieve' or 'list', relying on the tool name.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention exclusions or alternatives like np_query_spike_events or np_send_trigger, leaving the agent without decision-making support.

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