Vitest Agent Plugin Configuration

Plugin Options (vitest.config.ts)

The plugin is configured via AgentPlugin in your Vitest config:

import { AgentPlugin } from "@vitest-agent/plugin";
import { defineConfig } from "vitest/config";

export default defineConfig({
  plugins: [
    AgentPlugin({
      // Output format: "markdown" | "json" | "vitest-bypass" | "silent"
      format: "markdown",

      // Per-executor console matrix. The plugin auto-detects the
      // executor (human, agent, ci) and picks the matching slot.
      console: {
        human: "passthrough",   // Vitest's reporters render
        agent: "agent",         // markdown final-frame string
        ci: "passthrough",      // Vitest's reporters render
      },

      reporterOptions: {
        // Coverage thresholds (Vitest-native format)
        coverageThresholds: {
          lines: 80,
          branches: 80,
          functions: 80,
          statements: 80,
        },

        // Aspirational goals (informational, not enforced)
        coverageTargets: {
          lines: 95,
          branches: 90,
        },

        // Auto-ratchet baselines toward targets
        autoUpdate: true,

        // Max low-coverage files shown in console
        coverageConsoleLimit: 10,
      },
    }),
  ],
});

Common Configurations

Strict CI mode

AgentPlugin({
  format: "markdown",
  console: { agent: "agent" },
  reporterOptions: {
    coverageThresholds: { lines: 90, branches: 85 },
  },
})

Development mode (quiet)

AgentPlugin({
  format: "vitest-bypass",
  console: { human: "passthrough" },
})

Live Ink animation for humans

import { AgentPlugin } from "@vitest-agent/plugin";
import { createLiveInk, eventSourcedReporter } from "@vitest-agent/ui";

const live = createLiveInk();

AgentPlugin({
  console: { human: "ink", agent: "agent" },
  reporter: eventSourcedReporter,
  onRunEvent: live.event,   // fires only when human resolves to ink
})
