Use Coval by simulating conversations using prompts, transcripts, workflows, or audio inputs. Evaluate agent performance with built-in or custom metrics. Track regressions, compare results, and incorporate human-in-the-loop labeling. Monitor production calls, define alerts, and analyze performance.
Install the Mesa SDK, authenticate with a private key, create a versioned repository, and mount it as an isolated virtual filesystem. Define the repository layout and agent author information, then use standard filesystem operations or Unix commands to read, write, and execute files. Agents can create branches, run in parallel, submit changes for review, and restore previous filesystem checkpoints through the API.
