MCP Path

Screenshot Task-Isolation

Screenshot Task-Isolation is a public reference for visual evidence, screenshots, and reviewable differences. It names the signal, policy, or flow an agent should understand before choosing a concrete tool.

Purpose

What this entry explains

What it does

This reference explains Screenshot Task-Isolation for visual evidence, screenshots, and reviewable differences. It is kept as a named reference so agents can cite the flow without inventing a tool name.

Use when

  • Use this entry when an agent needs to start or monitor the bounded flow "Screenshot Task-Isolation" for visual evidence, screenshots, and reviewable differences.
  • Use it as a reference path when the catalog describes a capability but no single public tool name is explicit.
  • 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.

Signal, gate, behavior, boundary

Screenshot Task-Isolation describes a behavior for visual evidence, screenshots, and reviewable differences. The path shows which signal, gate, behavior, or boundary must be checked before choosing a concrete tool.

When agents cite it

An agent cites this path when it needs Screenshot Task-Isolation as context for a decision, block, target check, or follow-up tool choice.

Why no callable name

The public source does not name one callable tool for this path. The documentation therefore keeps it as a reference path and does not invent a callable name.

Signals and rule

Relevant response signals: screenshotFilePath, contextId, claimTaskId, mcpSessionId. Safety axes: Recording / media, Automation. The reference path alone is not permission to execute. Before acting, check current MCP discovery, visible target, scope, and the actual response.

Family example

A user needs visual or media evidence in visual evidence, screenshots, and reviewable differences without capturing private content unnecessarily.

The agent starts with nova.stream_url, reads the current response or reference, and only then chooses the concrete next tool.

Capture only needed evidence, keep recording state visible, and respect private content.

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 fieldExplanation
screenshotFilePathArtifact or evidence reference. Do not publish local values; use it for lookup, lifetime, or review context.
contextIdIdentifier or reference value. Do not guess it from memory; read it from the current response.
claimTaskIdIdentifier or reference value. Do not guess it from memory; read it from the current response.
mcpSessionIdIdentifier or reference value. Do not guess it from memory; read it from the current response.

Safety

Boundary before execution

Effect

Starts or observes a bounded run. Scope, limits, progress, and terminal status need to stay visible.

Agent rule

Set scope and limits before starting the run, poll explicit progress or status fields, and stop instead of assuming completion.

Human control

For humans, this entry shows which bounded flow in visual evidence, screenshots, and reviewable differences starts or continues, and where scope, progress, and stopping conditions belong.

High-Impact Review

Execution boundary and recheck hints

Review category: Recording/screenshots/media

Execution boundary

Capture only the needed visual or media evidence and respect private content, recording state, and export boundary.

Typical false assumption

False assumption: screenshots or recordings contain only technical evidence.

Visible user control

Recording, screenshot, media access, or export must be visible to the user and purpose-bound.

Agent rule

Before capture, check target, scope, and privacy; use artifacts as evidence only and do not forward them unrequested.

Abort or recheck

Abort if private content is visible, media permission is unclear, or the export contains more than needed.

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.

Recording / media recording_or_media

Creates or reads screenshots, recordings, media, visual evidence, or audio/video signals.

Capture only needed evidence, respect private content, and keep media or recording state visible.
Automation automation_run

Starts or monitors crawls, sequences, schedulers, tasks, batches, or longer runs.

Keep scope, budget, progress, stop condition, and terminal status visible before and during the run.
