MCP Tool
nova.traces_list
For page perception, diagnostics, and verifiable read signals, an agent uses this public tool to check the state or evidence for "Traces read". 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.traces_list
An agent uses this tool to check the state or evidence for "Traces read". It belongs to page perception, diagnostics, and verifiable read signals; 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 "Traces read" for page perception, diagnostics, and verifiable read signals.
- 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 task in page perception, diagnostics, and verifiable read signals can trigger powerful execution and therefore needs target, approval, and result check before the step.
The agent starts with nova.eval, reads the current response or reference, and only then chooses the concrete next tool.
Current discovery, target, user control, warning signals, and result check come before execution.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
No stable public input field is derived from the catalog source for this path. Read current MCP discovery before execution.
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.
Use the response as current evidence, then choose a more specific next tool only after target, scope, and freshness are clear.
For humans, this entry explains what an agent reads in page perception, diagnostics, and verifiable read signals and which current signal should be checked before trusting the result.
High-Impact Review
Execution boundary and recheck hints
Review category: Eval/CDP/diagnostics
Run only on the currently confirmed target; expression, expected result, and visible context must be clear before the call.
False assumption: because a script is intended to read, the path is automatically harmless.
The user must be able to see which page is targeted and why code, CDP, or diagnostics are being run.
Before execution, check current discovery, target, expression, and stop signal; do not derive additional scripts from the result.
Abort or recheck if the target changed, the expression touches third-party data, or the response contains warnings.
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.
