-## Mastra Master Reference
-
-This document is a single, practical reference for building with Mastra: agents, workflows, streaming, structured outputs, RAG, evals, and the new Network concepts. It favors concrete, type-safe patterns with Zod, shows end-to-end flows, and highlights operational practices so nothing is left to assumption.
-
-Where APIs evolve, verify against the official docs and examples:
-- Website: `https://mastra.ai/`
-- GitHub: `https://github.com/mastra-ai/mastra`

-## Setup and project scaffolding
-
-Install and scaffold a new Mastra project.
-
-```bash
-npm create mastra@latest
-cd your-project
-npm install
-```
-
-Add provider keys to `.env` (only the ones you use):
-
-```bash
-OPENAI_API_KEY=...
-ANTHROPIC_API_KEY=...
-GOOGLE_GENERATIVE_AI_API_KEY=...
-AZURE_OPENAI_API_KEY=...
-COHERE_API_KEY=...
-
-# Optional vector DBs
-DATABASE_URL=postgres://user:pass@host:5432/db  # for pgvector
-PINECONE_API_KEY=...
-QDRANT_URL=...
-QDRANT_API_KEY=...
-WEAVIATE_URL=...
-WEAVIATE_API_KEY=...
-```
-
-Recommended repo structure (kebab-case for dirs/files):
-
-```

-
----
-
-## Conventions for this repo (naming, structure)
-
-- Use PascalCase for components, type definitions, and interfaces.
-- Use kebab-case for directories and file names (e.g., `tools/vector-query-tool.ts`).
-- Use camelCase for variables, functions, methods, hooks, and props.
-- Prefix event handlers with `handle` (e.g., `handleSubmit`).
-- Prefix booleans with verbs like `is`, `has`, `can`.
-- Keep modules small and single-purpose; group by domain (agents, tools, workflows, rag, evals).
-- Store prompts and schemas under `src/lib/` to reuse across agents, tools, and steps.
-- Export registries so discoverability stays high:
-
-```ts
-// src/lib/registries.ts
-export const agents = { /* chefAgent, qaAgent */ };
-export const tools = { /* vectorQueryTool, fetchWeatherTool */ };
-export const workflows = { /* dataWorkflow, branchingWorkflow */ };
-```
-
----
-
-## Core concepts
-
-### Models and providers
-Mastra standardizes access to model providers via the AI SDK ecosystem. Import only what you need and keep it injectable.
-
-```ts
-import { openai } from "@ai-sdk/openai";
-// Example usage: openai("gpt-4o-mini")
-```
-
-Keep model choice configurable (env-driven) for portability and cost control.
-
-### Agents
-Agents encapsulate instructions, model config, memory, and available tools. They can also run within workflows.
-
-```ts
-import { Agent } from "@mastra/core";
-import { openai } from "@ai-sdk/openai";
-
-export const chefAgent = new Agent({
-  name: "Chef Agent",
-  instructions: "You are Michel, a practical home chef who gives specific, step-by-step cooking advice.",
-  model: openai("gpt-4o-mini"),
-  // memory: { ... }   // optional long/short-term memory strategies
-  // tools: [vectorQueryTool, webSearchTool],
-});
-```
-
-### Tools
-Tools are type-safe functions the agent/workflow can call. Always define schemas to ensure safe inputs/outputs.
-
-```ts
-import { createTool } from "@mastra/core";
-import { z } from "zod";
-
-export const fetchWeatherTool = createTool({
-  id: "fetch-weather",
-  description: "Fetch 24h forecast for a city.",
-  inputSchema: z.object({ city: z.string().min(1) }),
-  outputSchema: z.object({
-    city: z.string(),
-    forecast: z.array(z.object({ hour: z.number(), tempC: z.number() })),
-  }),
-  execute: async ({ inputData }) => {
-    // Call your API here; sanitize inputs; add retries/timeouts as needed
-    const res = await fetch(`https://api.example.com/forecast?city=${encodeURIComponent(inputData.city)}`);
-    const data = await res.json();
-    return { city: inputData.city, forecast: data.forecast };
-  },
-});
-```
-
-### Workflows
-Workflows are durable, graph-based state machines built from steps. Each step has typed input/output and an `execute` function.
-
-```ts
-import { createWorkflow, createStep } from "@mastra/core/workflows";
-import { z } from "zod";
-
-const fetchDataStep = createStep({
-  id: "fetch-data",
-  description: "Fetch JSON from a URL",
-  inputSchema: z.object({ url: z.string().url() }),
-  outputSchema: z.object({ data: z.unknown() }),
-  execute: async ({ inputData }) => {
-    const res = await fetch(inputData.url);
-    return { data: await res.json() };
-  },
-});
-
-const transformStep = createStep({
-  id: "transform",
-  description: "Map raw data to normalized form",
-  inputSchema: z.object({ data: z.unknown() }),
-  outputSchema: z.object({ normalized: z.any() }),
-  execute: async ({ inputData }) => {
-    // Implement your transformation here
-    return { normalized: inputData.data };
-  },
-});
-
-export const dataWorkflow = createWorkflow({ id: "data-workflow" })
-  .then(fetchDataStep)
-  .then(transformStep)
-  .commit();
-```
-
-Features you should leverage:
-- Branching/merging (decider steps) for control flow
-- Suspend/resume for human-in-the-loop
-- Orchestrate agents inside workflows, or expose workflows as tools
-
-### Memory
-Use a memory strategy appropriate to your use case (e.g., short-term conversational memory, long-term retrieval memory). Keep memory explicit: size, retention, privacy, and PII handling.
-
-### Storage
-Persist workflow runs, step states, and artifacts in your app database. For vectors, use a vector store (see RAG below).
-
-### Observability
-Adopt structured logging and distributed tracing early. Ensure every step logs inputs/outputs (redact secrets) and duration. Emit traces around model calls, tool calls, and vector queries.
-
----
-
-## Configuration and dependency injection (DI)
-
-Keep configuration explicit and validated; pass heavy dependencies in from the edges.
-
-```ts
-// src/lib/env.ts
-import { z } from "zod";
-
-const envSchema = z.object({
-  OPENAI_API_KEY: z.string().min(1),
-  DATABASE_URL: z.string().url().optional(),
-  LOG_LEVEL: z.enum(["fatal", "error", "warn", "info", "debug", "trace"]).optional(),
-  MODEL_NAME: z.string().optional().default("gpt-4o-mini"),
-});
-
-export const env = envSchema.parse(process.env);
-```
-
-```ts
-// src/lib/clients.ts
-import { openai } from "@ai-sdk/openai";
-import { env } from "./env";
-
-export function getLLM(model = env.MODEL_NAME) {
-  return openai(model);
-}
-```
-
-Pass clients via execution context or closures rather than importing globally inside steps/tools to simplify testing.
-
----
-
-## Logging and tracing
-
-Centralize logging and redact sensitive data; include run/step correlation IDs.
-
-```ts
-// src/lib/logger.ts
-import pino from "pino";
-
-export const logger = pino({
-  level: process.env.LOG_LEVEL ?? "info",
-  redact: { paths: ["req.headers.authorization", "context.secrets.*"], remove: true },
-  transport: process.env.NODE_ENV !== "production" ? { target: "pino-pretty" } : undefined,
-});
-```
-
-Use in steps/tools:
-
-```ts
-import { logger } from "../lib/logger";
-
-const start = Date.now();
-logger.info({ stepId: "fetch-data", url: inputData.url }, "step:start");
-try {
-  const res = await fetch(inputData.url);
-  const data = await res.json();
-  logger.info({ stepId: "fetch-data", ms: Date.now() - start }, "step:end");
-  return { data };
-} catch (err) {
-  logger.error({ stepId: "fetch-data", err }, "step:error");
-  throw err;
-}
-```
-
-Tracing: emit spans around model calls, vector queries, and remote tools (e.g., OpenTelemetry). Propagate `x-trace-id` across network boundaries and include it in logs.
-
----
-
-## Streaming
-
-Two common streaming modes:
-
-1) Token streaming from the model to your UI
-2) Event streaming of workflow/step progress to your UI
-
-### Token streaming (model → client)
-
-With the `ai` SDK models, stream tokens in your server route and forward to the browser (SSE or WebSocket). Example using SSE:
-
-```ts
-// server/routes/sse-stream.ts (Next.js route handler or any Node server)
-import { openai } from "@ai-sdk/openai";
-import { streamText } from "ai";
-
-export async function GET(req: Request) {
-  const url = new URL(req.url);
-  const userPrompt = url.searchParams.get("q") || "";
-
-  const stream = await streamText({
-    model: openai("gpt-4o-mini"),
-    prompt: userPrompt,
-  });
-
-  return new Response(stream.toAIStream(), {
-    headers: {
-      "Content-Type": "text/event-stream",
-      "Cache-Control": "no-cache, no-transform",
-      Connection: "keep-alive",
-    },
-  });
-}
-```
-
-### Workflow/run event streaming (steps → client)
-
-Stream step lifecycle events to the UI so users see long-running progress. Pattern:
-
-```ts
-// Pseudo-API: subscribe to a run's events and forward via SSE/WebSocket
-import { dataWorkflow } from "../workflows/data-workflow";
-
-export async function startAndStream(req: Request) {
-  const run = dataWorkflow.createRun();
-
-  const encoder = new TextEncoder();
-  const stream = new ReadableStream({
-    start(controller) {
-      run.on("event", (evt) => {
-        // evt: { stepId, status, startedAt, finishedAt, output? }
-        controller.enqueue(encoder.encode(`event: step\ndata: ${JSON.stringify(evt)}\n\n`));
-      });
-    },
-  });
-
-  // Kick off execution
-  await run.start({ inputData: { url: "https://api.example.com/data" } });
-
-  return new Response(stream, { headers: { "Content-Type": "text/event-stream" } });
-}
-```
-
-Notes:
-- Persist run state so reconnects can resume
-- Redact secrets before emitting events
-
----
-
-## Structured outputs
-
-Always make structure explicit with Zod. Validate at step and tool boundaries. Optionally, use model-side object generation when appropriate.
-
-```ts
-import { createStep } from "@mastra/core/workflows";
-import { z } from "zod";
-
-// Step with strict input/output
-export const summarizeStep = createStep({
-  id: "summarize",
-  inputSchema: z.object({ text: z.string().min(1) }),
-  outputSchema: z.object({ title: z.string(), bullets: z.array(z.string()) }),
-  execute: async ({ inputData, llm }) => {
-    // Use your preferred prompt; keep outputs aligned to schema
-    const title = `Summary of ${inputData.text.slice(0, 20)}...`;
-    const bullets = ["Bullet 1", "Bullet 2"]; // Replace with LLM call if desired
-    return { title, bullets };
-  },
-});
-```
-
-Model-driven object generation (optional pattern) using the `ai` SDK:
-
-```ts
-import { z } from "zod";
-import { generateObject } from "ai";
-import { openai } from "@ai-sdk/openai";
-
-const result = await generateObject({
-  model: openai("gpt-4o-mini"),
-  schema: z.object({ title: z.string(), bullets: z.array(z.string()) }),
-  prompt: "Summarize the following text into a title and 3 bullet points...",
-});
-
-// result.object is guaranteed to match the schema
-```
-
-Guidelines:
-- Keep schemas in `src/lib/schemas/` and import across steps/tools
-- Fail fast when parsing invalid outputs; log and retry with guardrails
-
----
-
-## RAG (Retrieval-Augmented Generation)
-
-A minimal, production-ready RAG pipeline has five parts:
-1) Ingestion (load + parse)
-2) Chunking (strategy + overlap)
-3) Embeddings (batching + rate limits)
-4) Vector store (upsert + filter + index)
-5) Query tool (embed query + search + rerank) used by an agent/workflow
-
-### Ingestion and chunking
-
-```ts
-import { MDocument } from "@mastra/rag";
-
-// From raw text; also support PDFs/HTML/Markdown via appropriate loaders
-const doc = MDocument.fromText("Your document content here...");
-const chunks = await doc.chunk({
-  strategy: "recursive", // keep semantic boundaries
-  size: 512,
-  overlap: 50,
-  separator: "\n",
-});
-```
-
-### Embeddings
-
-```ts
-import { embedMany } from "ai";
-import { openai } from "@ai-sdk/openai";
-
-const { embeddings } = await embedMany({
-  values: chunks.map((c) => c.text),
-  model: openai.embedding("text-embedding-3-small"),
-});
-```
-
-### Vector store (example: pgvector)
-
-```ts
-// src/rag/stores/pgvector.ts
-import { PgVector } from "@mastra/pg";
-
-export const pgVector = new PgVector(process.env.DATABASE_URL!);
-
-export async function upsertEmbeddings(indexName: string, vectors: number[][], metadatas: unknown[]) {
-  await pgVector.upsert({ indexName, vectors, metadatas });
-}
-
-export async function queryEmbeddings(indexName: string, queryVector: number[], topK = 5) {
-  return pgVector.query({ indexName, queryVector, topK });
-}
-```
-
-Stores commonly used with Mastra: pgvector (Postgres), Pinecone, Qdrant, Weaviate, MongoDB Vector. Choose based on latency, filtering, ops comfort, and cost. Keep a unified API in your app so stores are swappable.
-
-### Vector query tool (agentic RAG)
-
-```ts
-// src/tools/vector-query-tool.ts
-import { createTool } from "@mastra/core";
-import { z } from "zod";
-import { embed } from "ai";
-import { openai } from "@ai-sdk/openai";
-import { queryEmbeddings } from "../rag/stores/pgvector";
-
-export const vectorQueryTool = createTool({
-  id: "vector_query",
-  description: "Search relevant chunks from the knowledge base.",
-  inputSchema: z.object({ query: z.string(), topK: z.number().int().min(1).max(20).default(5) }),
-  outputSchema: z.object({
-    results: z.array(
-      z.object({ id: z.string().optional(), score: z.number(), text: z.string(), metadata: z.record(z.any()).optional() })
-    ),
-  }),
-  execute: async ({ inputData }) => {
-    const { embedding } = await embed({ model: openai.embedding("text-embedding-3-small"), value: inputData.query });
-    const raw = await queryEmbeddings("kb-embeddings", embedding, inputData.topK);
-    const results = raw.map((r: any) => ({ id: r.id, score: r.score, text: r.text, metadata: r.metadata }));
-    return { results };
-  },
-});
-```
-
-### Agent that uses the RAG tool
-
-```ts
-import { Agent } from "@mastra/core";
-import { openai } from "@ai-sdk/openai";
-import { vectorQueryTool } from "../tools/vector-query-tool";
-
-export const qaAgent = new Agent({
-  name: "KB QA Agent",
-  instructions: "Answer strictly using provided context. If unsure, say you don’t know and suggest next steps.",
-  model: openai("gpt-4o-mini"),
-  tools: [vectorQueryTool],
-});
-```
-
-Reranking (optional): add a re-ranker model (or an LLM judging prompt) to improve top-K ordering before final answer generation.
-
----
-
-## Evals
-
-Evals keep quality measurable during development and CI. Use both rule-based and model-graded checks. Keep datasets versioned.
-
-Recommended approach:
-- Define metrics: answer relevancy, context recall, faithfulness, structure validity, toxicity, latency, cost
-- Build small eval workflows that take (query, reference, output, context) and return numeric scores with rationales
-- Run ad hoc locally during development; run in CI on pull requests with thresholds
-
-Example: a lightweight, model-graded relevancy evaluator step:
-
-```ts
-import { createStep } from "@mastra/core/workflows";
-import { z } from "zod";
-import { openai } from "@ai-sdk/openai";
-import { generateText } from "ai";
-
-export const answerRelevancyEval = createStep({
-  id: "answer-relevancy-eval",
-  inputSchema: z.object({ question: z.string(), answer: z.string() }),
-  outputSchema: z.object({ score: z.number().min(0).max(1), rationale: z.string() }),
-  execute: async ({ inputData }) => {
-    const prompt = `Rate from 0 to 1 how directly the ANSWER addresses the QUESTION. Provide a brief rationale.\nQUESTION: ${inputData.question}\nANSWER: ${inputData.answer}`;
-    const { text } = await generateText({ model: openai("gpt-4o-mini"), prompt });
-    // Parse your score and rationale from text (or generate structured JSON via generateObject)
-    const match = text.match(/score\s*[:=]\s*(0(\.\d+)?|1(\.0+)?)/i);
-    const score = match ? Math.min(1, Math.max(0, Number(match[0].split(/[:=]/)[1]))) : 0;
-    return { score, rationale: text };
-  },
-});
-```
-
-Operational tips:
-- Store eval results with run metadata (model, prompt revision, dataset version)
-- Visualize score trends; fail CI when scores regress beyond thresholds
-
----
-
-## Workflows (advanced semantics)
-
-Use decider steps for branching and error policy for retries/timeouts. Keep steps small and composable.
-
-```ts
-import { createWorkflow, createStep } from "@mastra/core/workflows";
-import { z } from "zod";
-
-const decidePath = createStep({
-  id: "decide-path",
-  inputSchema: z.object({ value: z.number() }),
-  outputSchema: z.object({ route: z.enum(["A", "B"]) }),
-  execute: async ({ inputData }) => ({ route: inputData.value > 0 ? "A" : "B" }),
-});
-
-const pathA = createStep({ id: "path-A", inputSchema: z.object({}), outputSchema: z.object({ done: z.literal(true) }), execute: async () => ({ done: true }) });
-const pathB = createStep({ id: "path-B", inputSchema: z.object({}), outputSchema: z.object({ done: z.literal(true) }), execute: async () => ({ done: true }) });
-
-export const branchingWorkflow = createWorkflow({ id: "branching" })
-  .then(decidePath)
-  .after(decidePath)
-    .step(pathA)
-    .step(pathB)
-  .commit();
-```
-
-Human-in-the-loop: pause after a step, persist state, await approval/input, then resume. Ensure idempotent steps and durable state to safely retry.
-
----
-
-## Network (new)
-
-Network refers to composing agents/workflows/tools across service boundaries (process, machine, org). Treat tools as your stable interface and call them over the network with strong typing and auth.
-
-Patterns that map cleanly to Mastra today:
-- Expose tools behind HTTP/GraphQL endpoints; call them from `createTool` executors
-- Use signed requests, scopes, and rate limits; never pass raw keys to the client
-- Maintain a registry (service discovery) mapping tool IDs to network locations; version tool contracts via schemas
-- Emit tracing headers across boundaries for end-to-end observability
-
-Example: a tool that calls a remote service (conceptually “network tool”):
-
-```ts
-import { createTool } from "@mastra/core";
-import { z } from "zod";
-
-export const remoteInvoiceTool = createTool({
-  id: "remote-invoice:create",
-  description: "Create an invoice in the Accounting Service.",
-  inputSchema: z.object({ customerId: z.string(), amountCents: z.number().int().positive() }),
-  outputSchema: z.object({ invoiceId: z.string(), status: z.enum(["created", "queued"]) }),
-  execute: async ({ inputData, context }) => {
-    const res = await fetch(`${process.env.ACCOUNTING_BASE_URL}/invoices`, {
-      method: "POST",
-      headers: { "Content-Type": "application/json", Authorization: `Bearer ${context.secrets.ACCOUNTING_TOKEN}` },
-      body: JSON.stringify(inputData),
-    });
-    if (!res.ok) throw new Error(`Remote error ${res.status}`);
-    return res.json();
-  },
-});
-```
-
-Security and governance:
-- Validate all inputs with Zod; reject on schema mismatch
-- Sign/verify requests (JWT or mTLS); enforce least-privilege scopes per tool
-- Log and trace every remote call with correlation IDs
-
-As first-class “Network” capabilities mature in Mastra, prefer official registries, permissioning, and remote tool invocation APIs when available. Until then, the pattern above keeps contracts explicit and safe.
-
----
-
-## Testing and maintenance (unit, integration, mocking)
-
-Testing pyramid for Mastra apps:
-- Unit tests: functions, tools, and steps with mocked dependencies
-- Integration tests: workflows end-to-end with test doubles for external HTTP
-- Contract tests: schemas for tools and steps validated with sample payloads
-
-Recommended setup (Vitest):
-
-```ts
-// src/tools/__tests__/vector-query-tool.test.ts
-import { describe, it, expect, vi } from "vitest";
-import { vectorQueryTool } from "../vector-query-tool";
-
-vi.mock("../../rag/stores/pgvector", () => ({
-  queryEmbeddings: vi.fn(async () => [{ id: "1", score: 0.9, text: "chunk", metadata: { source: "test" } }]),
-}));
-
-describe("vectorQueryTool", () => {
-  it("returns results from vector store", async () => {
-    const out = await vectorQueryTool.execute({ inputData: { query: "hello", topK: 3 } } as any);
-    expect(out.results.length).toBeGreaterThan(0);
-  });
-});
-```
-
-HTTP recording: use `nock` or `msw` for deterministic tests. Keep fixtures in `test/fixtures/` and sanitize secrets.
-
-Maintenance:
-- Encapsulate provider-specific code in `lib/clients.ts`
-- Keep schemas and prompts centralized; version prompts when changed
-- Document each agent/tool/workflow with a brief README near the module
-
----
-
-## Best practices
-
-- Type safety first: every boundary uses Zod; no `any` types
-- Keep steps/tools small, pure where possible; avoid hidden state
-- Centralize model/provider selection (env) and log model, temperature, maxTokens per call
-- RAG: benchmark retrieval; filter by metadata; consider reranking; keep chunking domain-aware
-- Streaming: back-pressure and timeouts; redact PII in events
-- Evals: store scores and rationales; fail CI on regressions; regularly refresh datasets
-- Observability: structured logs, traces around LLM/tool/vector calls
-- Cost: track tokens per feature; set budgets/alerts
-- Security: sanitize inputs, never expose secrets to clients, rate-limit tools
-- Testing: unit-test steps/tools; integration-test workflows; record/replay external HTTP
-
----
-
-## Intern onboarding checklist
-
-- Read `plan/00-mastra-master-reference.md` end-to-end
-- Set up `.env` with only the keys you need; never commit secrets
-- Run a local example: start the SSE route and test streaming
-- Add a new tool: implement input/output schema, logging, and a unit test
-- Add a small workflow: 2–3 steps with a decider; include an integration test
-- Build a tiny RAG dataset: ingest 1–2 docs, upsert embeddings, and query via the tool
-- Add one eval: model-graded relevancy; wire into a CI job with a basic threshold
-- Confirm logs show correlation IDs and durations for steps and model calls
