His mass–energy equivalence formula E = mc2, which arises from relativity theory, has been called \"the world's most famous equation\". He received the 1921 Nobel Prize in Physics \"for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect\", a pivotal step in the development of quantum theory.

LLM-Based Scorers + +Leverage language models for sophisticated evaluation: + +```typescript +import { Agent } from "@voltagent/core"; +import { openai } from "@ai-sdk/openai"; +import { z } from "zod"; + +const QUALITY_SCHEMA = z.object({ + score: z.number().min(0).max(10), + reason: z.string(), +}); + +const qualityScorer = buildScorer({ + id: "quality-check", + label: "Response Quality", +}) + .analyze(async ({ payload }) => { + const agent = new Agent({ + name: "quality-evaluator", + model: openai("gpt-4o-mini"), + instructions: "You evaluate response quality on a scale of 0-10", + }); + + const prompt = `Rate the quality of this response: ${payload.output}`; + const result = await agent.generateObject(prompt, QUALITY_SCHEMA); + + return result.object; + }) + .score(({ results }) => { + const analysis = results.analyze as z.infer; + return { + score: analysis.score / 10, + metadata: { rating: analysis.score, reason: analysis.reason }, + }; + }) + .build(); +``` + +### 3.

Type Safety + +Define clear interfaces for your scorer payloads: + +```typescript +interface SentimentPayload { + output: string; + targetSentiment: "positive" | "negative" | "neutral"; +} + +const typedScorer = buildScorer({ + id: "typed-sentiment", + label: "Typed Sentiment", +}) + .score(({ payload }) => { + // TypeScript knows payload structure + const isPositive = payload.targetSentiment === "positive"; + return { score: isPositive ? 1.0 : 0.0 }; + }) + .build(); +``` + +### 2. Error Handling + +Make your scorers resilient to unexpected inputs: + +```typescript +.prepare(({ payload }) => { + try { + const text = String(payload.output || ""); + if (!text) throw new Error("Empty output"); + return { text }; + } catch (error) { + return { text: "", error: error.message }; + } +}) +``` + +### 3. Performance Optimization + +- Use `prepare` to validate and clean data once +- Cache expensive computations in `analyze` +- Keep `score` lightweight for fast execution +- Use `reason` only when explanations are needed + +### 4. Testing Your Scorers + +```typescript +import { describe, it, expect } from "vitest"; + +describe("sentimentScorer", () => { + it("detects positive sentiment", async () => { + const result = await sentimentScorer.run({ + payload: { + output: "This is excellent!", + targetSentiment: "positive", + }, + params: {}, + }); + + expect(result.score).toBe(1.0); + expect(result.metadata.detectedSentiment).toBe("positive"); + }); + + it("handles empty input", async () => { + const result = await sentimentScorer.run({ + payload: { + output: "", + targetSentiment: "positive", + }, + params: {}, + }); + + expect(result.score).toBeDefined(); + expect(result.reason).toContain("neutral"); + }); +}); +``` + +## Pipeline Visualization + +The scorer pipeline flows through each step sequentially: + +``` +Input Payload + ↓ +┌─────────────┐ +│ Prepare │ → Transform & validate input +└─────────────┘ + ↓ +┌─────────────┐ +│ Analyze │ → Extract features & insights +└─────────────┘ + ↓ +┌─────────────┐ +│ Score │ → Calculate numeric score (0-1) +└─────────────┘ + ↓ +┌─────────────┐ +│ Reason │ → Generate explanation +└─────────────┘ + ↓ +Final Result +``` + +Each step has access to: + +- `payload`: Original input data +- `params`: Parameters for this evaluation +- `results`: Outputs from previous steps + - `results.prepare`: Output from prepare step + - `results.analyze`: Output from analyze step + - `results.raw`: All raw results for debugging + +## Advanced Patterns + +### Using Parameters + +Parameters allow customization per evaluation run: + +```typescript +interface KeywordParams { + keyword: string; + caseSensitive?: boolean; +} + +const keywordScorer = buildScorer, KeywordParams>({ + id: "keyword-match", + params: { caseSensitive: false }, // default +}) + .score(({ payload, params }) => { + const output = String(payload.output); + const keyword = params.keyword; + const caseSensitive = params.caseSensitive ?? false; + + const match = caseSensitive + ? output.includes(keyword) + : output.toLowerCase().includes(keyword.toLowerCase()); + + return match ? 1 : 0; + }) + .build(); +``` + +### Dynamic Parameters + +Parameters can be derived from the payload: + +```typescript +const dynamicScorer = buildScorer({ + id: "dynamic-params", + params: (payload) => ({ + expectedCategory: payload.category, + threshold: payload.confidence ?? 0.8, + }), +}) + .score(({ payload, params }) => { + const match = payload.output === params.expectedCategory; + return match ? 1 : 0; + }) + .build(); +``` + +### Weighted Composite Scorers + +Combine multiple scoring functions with `weightedBlend`: + +```typescript +import { weightedBlend } from "@voltagent/core"; + +const compositeScorer = buildScorer({ + id: "composite", +}) + .score( + weightedBlend([ + { + id: "length", + weight: 0.3, + step: ({ payload }) => { + const length = String(payload.output).length; + return Math.min(length / 500, 1); + }, + }, + { + id: "quality", + weight: 0.7, + step: async ({ payload }) => { + // Call LLM judge + const result = await evaluateQuality(payload.output); + return result.score; + }, + }, + ]) + ) + .build(); +``` + +## Next Steps + +- Explore [pre-built scorers](./prebuilt-scorers.md) for common evaluation needs +- Learn about [offline evaluations](./offline-evaluations.md) for batch testing +- Configure [Agent evaluations](./live-evaluations.md) for real-time monitoring diff --git a/website/docs/evals/cli-reference.md b/website/docs/evals/cli-reference.md new file mode 100644 index 000000000..4cf91e3b6 --- /dev/null +++ b/website/docs/evals/cli-reference.md @@ -0,0 +1,399 @@ +--- +title: CLI Commands Reference +sidebar_position: 8 +--- + +# CLI Commands Reference + +The VoltAgent CLI provides commands for managing datasets and running experiments.

The same experiment definition can run locally, in automation, or from a dashboard, while VoltOps captures detailed telemetry and scoring breakdowns. -Evaluation (evals) helps you measure and improve your AI agent's performance. VoltAgent uses [**Viteval**](https://github.com/viteval/viteval) as its official evaluation framework, providing a simple yet powerful way to test your agents. +This page explains the big picture: what makes up an evaluation, how runs flow from your code to VoltOps, and where to look next when you’re ready to dive in. -## Why Evals Matter +## Why run evaluations? -Without evaluation, you're building agents blindfolded. Evals help you: +- **Catch regressions before they ship.** Re-run the same dataset whenever a prompt or model changes and spot drops in accuracy or quality. +- **Standardise measurement.** A single experiment can mix multiple scorers (exact match, semantic similarity, moderation, LLM judges, …) and compute pass thresholds automatically. +- **Close the loop with VoltOps.** Every offline run shows up alongside your live traffic, with the same tags, filters, and search you already use to debug agents. +- **Scriptable & repeatable.** Experiments are plain TypeScript modules, so you can version them, share them, and run them in any Node.js environment. -- **Ensure Quality**: Catch issues before users do -- **Track Performance**: See if changes improve or break your agent -- **Build Confidence**: Know your agent works as expected -- **Meet Standards**: Validate safety and accuracy requirements +## Core building blocks -## What Gets Evaluated +| Concept | Responsibility | +| ---------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | +| **Experiment definition** (`createExperiment`) | Describes the run: dataset source, how to invoke your agent/runner, which scorers to apply, and any pass criteria. | +| **Runner** | A function that receives one dataset item and returns the agent output (plus optional metadata / traces). | +| **Dataset** | The evaluation inputs. Can be inline JSON, generated on the fly, or pulled from VoltOps. | +| **Scorers** | Re-usable scoring functions (exact match, embeddings, LLM graders, moderation, etc.) that produce scores, thresholds, and metadata. | +| **Aggregator** | Computes summary stats (mean score, pass rate, threshold compliance) and overall pass/fail. | +| **VoltOps integration** | Optional client that automatically creates a run, streams item results, and finalises the summary so you can inspect everything in the Console. | -### Agent Responses +## How it fits with the rest of VoltAgent -- **Accuracy**: Are the facts correct? -- **Relevance**: Does it answer the question? -- **Helpfulness**: Is it useful to the user? -- **Safety**: No harmful or inappropriate content? +- **Agents & workflows.** Experiments call into your agent code (e.g. the same functions your API or workflow uses). It’s your runner’s responsibility to invoke the agent with the right inputs. +- **VoltOps telemetry.** Runs appear alongside live traces. You get the same search, tagging, and drill-down experience for offline and online evaluation. +- **Scorer registry.** `@voltagent/scorers` ships ready-made graders (string similarity, number comparison, LLM judges). You can also write custom scorers or wrap external services. +- **Datasets.** Reuse the same dataset whether you run from CLI, CI, or VoltOps’s UI. The framework supports inline, generated, and VoltOps-hosted sources. -### Agent Behavior +## Offline Evaluations -- **Tool Usage**: Does it use the right tools correctly? -- **Following Instructions**: Does it stick to its role? -- **Consistency**: Similar inputs get similar outputs? +Offline evaluations run against a fixed dataset, return deterministic scores, and are ideal for regression testing, CI gates, and comparing branches. -## Viteval Integration +### End-to-End Flow -VoltAgent works seamlessly with Viteval: +1. **Define the experiment.** Import `createExperiment`, choose a dataset, and set up your runner. -```typescript -// In your agent file (e.g., src/agents/support.ts) -import { Agent } from "@voltagent/core"; + ```ts + // experiments/support-nightly.experiment.ts + import { createExperiment } from "@voltagent/evals"; + + export default createExperiment({ + id: "support-nightly", + dataset: { name: "support-nightly" }, + runner: async ({ item }) => ({ output: item.input }), + }); + ``` + +2. **Resolve the dataset.** Inline arrays run as-is; named datasets pull from VoltOps or a registry. + + ```ts + dataset: { + items: [ + { id: "greeting", input: "hello", expected: "hello" }, + { id: "farewell", input: "goodbye", expected: "goodbye" }, + ], + }; + + // or + dataset: { name: "support-nightly" }; + ``` + +3. **Execute the runner.** Call your agent and collect outputs/metadata. + + ```ts + runner: async ({ item }) => { + const reply = await supportAgent.generateText(item.input); + return { output: reply.text, metadata: { tokens: reply.usage?.total_tokens } }; + }; + ``` + +4. **Score the result.** Combine scorers with thresholds or LLM judges. + + ```ts + import { scorers } from "@voltagent/scorers"; + + scorers: [scorers.exactMatch, scorers.embeddingSimilarity({ expectedMin: 0.8 })]; + ``` + +5. **Aggregate and apply pass criteria.** + + ```ts + passCriteria: { type: "passRate", min: 0.95 }; + ``` + +### Running offline evals + +You can execute the experiment either from the CLI or directly in Node.js: + +```bash title="CLI" +npm run volt eval run \ + -- --experiment ./src/experiments/support-nightly.experiment.ts \ + --concurrency 4 +``` + +```ts title="Node script" +import { VoltOpsRestClient } from "@voltagent/sdk"; +import { runExperiment } from "@voltagent/evals"; +import experiment from "./experiments/support-nightly.experiment"; + +const voltOpsClient = new VoltOpsRestClient({ + publicKey: process.env.VOLTAGENT_PUBLIC_KEY, + secretKey: process.env.VOLTAGENT_SECRET_KEY, +}); + +const result = await runExperiment(experiment, { + voltOpsClient, + concurrency: 4, + onProgress: ({ completed, total }) => console.log(`Processed ${completed}/${total ??
