MCP Tool
nova.explain
For knowledge signals, learning candidates, and explainable orientation, an agent uses this public tool to check the state or evidence for "Explain PKS Level". It explains which current signal can be used as evidence and when a follow-up step needs a fresh target check.
Canonical reference for a public MCP tool name.

Purpose
What this entry explains
What it does
nova.explain
An agent uses this tool to check the state or evidence for "Explain PKS Level". It belongs to knowledge signals, learning candidates, and explainable orientation; agents should combine it with current discovery, target awareness, and the visible result.
Use when
- Use this entry when an agent needs to check the state or evidence for "Explain PKS Level" for knowledge signals, learning candidates, and explainable orientation.
- Use it to understand the public tool name, its expected boundary, and the response signals to check.
- Use it before chaining follow-up tools so the next step is based on current evidence.
Reference Use
How agents should cite and apply this area
Examples are maintained at family level and use only public tool names or reference paths already present in the catalog.
Family example
A user asks for the current state in knowledge signals, learning candidates, and explainable orientation before an agent chooses the next browser or tool step.
The agent starts with nova.explain, reads the current response or reference, and only then chooses the concrete next tool.
The response is evidence for the next decision, but not approval for a follow-up action without a fresh target check.Contract
Inputs and important response fields
This page is a public reference. Agents and integrators should still read current MCP tool discovery before execution, because schemas can be gated by settings or version.
Inputs
phenomenonId
Reference key for the current target, object, or session. Read it from the current response instead of guessing.
Response fields
No fixed public response field is derived from the catalog source for this path. Use current tool discovery and the actual response before chaining the next step.
Safety
Boundary before execution
Reads current state or evidence. It should not be treated as permission to act without a fresh next-step check.
Treat stored knowledge as guidance only. Before any action, confirm the current page, target, scope, and visible evidence again.
For humans, this entry explains what an agent reads in knowledge signals, learning candidates, and explainable orientation and which current signal should be checked before trusting the result.
Safety Axes
How this path can affect work
Axes are stable catalog signals for humans, agents, and LLM discovery. One path can carry several axes.
read_current_state
Reads current state, response signals, or evidence without treating that alone as permission for a follow-up action.
Use the signal as current evidence and re-check target, scope, and visible state before any follow-up action.
