Experiments View

Manage and run experiments from a centralized view in the FluxLoop Activity Bar.

Overview​

The Experiments view provides quick access to your current experiment configuration, recording mode controls, and recent experiment runs. It serves as the main control panel for experiment execution.

Features​

Current Experiment​

Displays configuration from configs/simulation.yaml:

  • Configuration file: Click to open in editor
  • Runner: Shows module_path and function_name
  • Iterations: Current iteration count from config
  • Record Mode: Shows if argument recording is enabled

If no simulation config exists, shows placeholder message.

Run Experiment​

Root-level action button (no need to expand folders):

  1. Click to start experiment execution
  2. Select environment (Local Python/Dev Container/Docker)
  3. Optionally override iteration count
  4. Runs in new terminal at project root

See Running Experiments for details.

Recording Mode​

Collapsible section with three actions:

  • Enable Recording Mode: Turns on argument recording (updates .env and config)
  • Disable Recording Mode: Turns off argument recording
  • Show Recording Status: Displays current recording state in terminal

For complex agents (WebSocket handlers, callbacks), recording captures actual arguments for replay. See Recording Mode Guide.

Experiments Folder​

Lists recent experiment runs (same as Results view):

  • Grouped under Experiments for organization
  • Shows up to 10 most recent runs
  • Each displays timestamp and success rate
  • Expand to see artifact files

Recordings​

Shows recorded argument files from recordings/ directory:

  • Lists up to 10 most recent .jsonl files
  • Click to open recording file
  • Used for argument replay during experiments

Actions​

Run Experiment​

Executes fluxloop run experiment with selected environment and optional iteration override.

Open Configuration​

Opens configs/simulation.yaml in editor for direct editing.

Recording Controls​

  • Enable: Runs fluxloop record enable (or uses VSCode command)
  • Disable: Runs fluxloop record disable
  • Status: Runs fluxloop record status

File Watchers​

The Experiments view automatically refreshes when:

  • configs/simulation.yaml is modified
  • .env file changes (affects recording status)
  • New experiments complete in experiments/
  • Recording files are added to recordings/

Tips​

  • Quick Run: Run Experiment is always visible at root level for fast access
  • Config Editing: Click Open configuration to directly edit simulation settings
  • Recording Toggle: Enable/disable recording without manual config editing
  • Experiment History: Recent runs appear here; full history in Results view
