Environment Factory: SDK Setup & Validation

You are a backend engineer. Your job is to install the Autonoma SDK, configure the handler with factories, and validate the scenario lifecycle for this application.

CRITICAL: Database Safety

You may be connected to a production database. Follow these rules absolutely:

• ALL writes go through the SDK endpoint only. The SDK has production guards, HMAC authentication, and signed refs tokens that prevent accidental damage.
• You MAY read from the database using psql, database GUIs, or ORM queries for verification purposes (SELECT only).
• You MUST NEVER run INSERT, UPDATE, DELETE, DROP, or TRUNCATE directly via psql, raw SQL, ORM write methods, or any other path outside the SDK endpoint.
• You MUST NEVER delete the whole database, truncate tables, or run destructive migrations.
• The SDK’s down action only deletes records that up created, verified by a cryptographically signed token. This is the only safe deletion path.

HARD CONTRACT — READ FIRST

You MUST NOT:

• Create a new server, app, or sidecar process. No new FastAPI() / express() / Flask() / standalone main.py / start-*.py / main.go launcher at the repo root.
• Install a Python SDK into a TypeScript backend (or vice versa). The SDK language MUST match the backend’s language.
• Scaffold files at the repo root when an existing backend directory exists — even if that directory is named core-app-backend/, apps/api/, services/core/, or any other non-standard name.
• Pick an SDK before you have located and identified the backend in Phase 1.

If you cannot locate a backend, or the backend’s language has no matching Autonoma SDK, STOP and ask the user. Never fall back to a sidecar.

Phase 0: Locate prerequisites

0.1 — Find scenarios.md

1. Check for autonoma/scenarios.md at the workspace root.
2. If not found, search broadly for scenarios.md anywhere in the workspace.

If not found, tell the user:

“I need scenarios.md to implement the Environment Factory. Please run the Scenario Generator (Step 2) first, then come back and run this prompt.”

Do not proceed without it.

0.2 — Read the Environment Factory documentation

Fetch the Autonoma documentation to understand the current SDK setup:

1. Fetch https://docs.agent.autonoma.app/llms.txt to get the documentation index
2. Read the Environment Factory Guide — understand the SDK packages, factory registration with inputSchema / input_model, the scopeField on HandlerConfig, auth callback patterns, and the create tree format
3. Read the framework example that matches this project’s stack if one exists

Always read the live docs. The SDK may have been updated since this prompt was written.

0.3 — Read scenarios.md

Read scenarios.md fully. Identify:

• The scenario names and their create trees
• Every model referenced in the create trees
• Cross-branch references (_alias / _ref)
• Fields that use testRunId for uniqueness

Phase 1: Explore the codebase

This exploration builds your understanding of the project — the same understanding that determines factory registration and auth implementation.

1.1 — Locate the backend and detect its language (do this BEFORE anything else in Phase 1)

Real projects use many directory conventions. Do NOT hardcode backend/. Enumerate candidates with Glob:

• backend/, server/, api/, service/, services/
• *-backend/, *-api/, *-server/, core-*/, app-*/, core-app-backend/
• Monorepo layouts: apps/*, packages/*, services/*
• Single-repo backends at the workspace root

Detect language per candidate from its manifest file — this determines which Autonoma SDK you install:

Pick exactly one backend. If multiple plausible candidates exist, STOP and ask the user. Do not guess. Do not implement in more than one.

State your finding back to the user before writing any code:

“I found the backend at <path> (language: <lang>, framework: <framework>). I’ll implement the endpoint there using the <sdk-package> SDK. Is that the right location?”

Wait for confirmation.

If no candidate matches a supported SDK language: STOP and ask the user. Do NOT build a standalone Python (or any) sidecar as a workaround. Do NOT install a language SDK that doesn’t match the backend.

If the backend is in a separate repo not open in this workspace: generate a self-contained prompt the user can run in the backend workspace, including the full scenarios.md content, a link to the live docs, and all implementation instructions. Do not create a sidecar in the current workspace.

1.2 — Understand the stack

Identify:

• Framework: Next.js, Express, Hono, FastAPI, Flask, Django, etc.
• DB layer: Whatever ORM/repository pattern the app already uses — your factories will call those services directly. The SDK does not need a connection.
• Auth mechanism: How users log in (session cookies, JWT, OAuth, Better Auth, Lucia, etc.)
• Existing route patterns: How other endpoints are structured

1.3 — Read entity-audit.md

Read autonoma/entity-audit.md and parse the frontmatter. The audit tells you exactly which models to wire up:

• Every model in the audit gets a factory. The SDK is factory-driven: there is no SQL fallback. Every factory must declare an inputSchema (Zod) / input_model (Pydantic) so the SDK can describe the model to the dashboard and validate the create payload before invoking your code.
• Models with independently_created: true get a factory that calls the identified creation_file / creation_function.
• Models with independently_created: false still need a factory, but it can be a thin repository call (db.tag.create({...}) / repo.tag.create(...)) since there’s no shared business logic to preserve.

The audit’s side_effects field is informational — it helps you understand what each factory will preserve.

1.4 — Understand auth creation

Find the code path that creates sessions or tokens for users. Search for createSession, jwt.sign, lucia, better-auth, iron-session, or similar. You need to replicate this in the auth callback.

Phase 2: Plan — go into plan mode

Present a complete implementation plan:

## Implementation Plan

### SDK packages to install
[Exact packages: `@autonoma-ai/sdk` + `@autonoma-ai/server-<framework>` + `zod` (TS), or `autonoma-ai` (Python). No ORM-specific package — factories use whatever client the app already has.]

### Endpoint location
[Exact file path]

### Scope field
[e.g., organizationId — explain why]

### Environment variables
- `AUTONOMA_SHARED_SECRET` — shared with Autonoma for HMAC request verification
- `AUTONOMA_SIGNING_SECRET` — private, for signing refs tokens

### Factories to register (from entity-audit.md)
For every model the audit lists, register a factory. Each one declares:
- `inputSchema` (Zod) / `input_model` (Pydantic): every dashboard-supplied field, with the right type. Drives discover.
- `create`: invokes the audit's `creation_file` / `creation_function` for `independently_created: true`, or a thin repository call for `independently_created: false`.
- `teardown`: optional but recommended — invoked during `down` to remove what `up` created.

For every `independently_created: true` row, name the function the factory calls and the side effects observed in the audit. For `independently_created: false`, name the table the factory writes to.

### Auth callback strategy
[How sessions/tokens are created — specific code path in the app]

Wait for user approval before proceeding.

Phase 3: Implement

2.5 — Research pass (MANDATORY before writing any factory)

Post-mortems of past runs show a consistent failure mode: the agent makes one bad decision and applies it uniformly to every model. The research pass prevents this by forcing a per-model pause and a documented decision before any handler code is written.

Emit autonoma/.factory-plan.md with one row per independently_created: true model:

| Model | Audit function | File opened? | Import path | DI dependencies observed | Decision (Branch 1/2/3) | Notes |
|-------|----------------|--------------|-------------|--------------------------|-------------------------|-------|

Column rules:

• File opened? — “yes, lines X-Y” or “no, why”. If “no”, you MUST NOT proceed — you cannot pick Branch 1 vs Branch 2 without reading the source.
• Import path — the exact import ... from "..." the handler will use. For Branch 1 rows, this is the new export you will create during extraction, not the current inline location.
• DI dependencies observed — every constructor arg or closed-over variable the function uses (DB client, logger, event bus, Temporal client, analytics client, etc.). The factory has no ctx.executor to lean on; it imports the same DB client / repository singletons the rest of the app uses. Listing every dependency makes any silent give-up visible.
• Decision — Branch 1 (extract inline → export → call), Branch 2 (import existing export → call), or Branch 3 (independently_created: false, plain repository call is fine). “Inline ORM in production code path” is NOT a valid value for Branches 1 or 2.

Cross-codebase DI discovery

Run these greps against the backend BEFORE filling the table:

# Find how each service is actually constructed in production code.
grep -rnE "new ${ServiceName}\(" apps/ --include='*.ts' --include='*.tsx' | head -20
# Find exported singletons and module-level instances.
grep -rnE "^(export )?(const|let) [a-zA-Z]+ = new " apps/ --include='*.ts' | head -40
# Find composition root candidates.
grep -rnlE "(container|registry|services/index|app\.module)" apps/ | head

Use the results to fill “DI dependencies observed” honestly. If a service needs logger, eventBus, temporal, analytics and you can’t find where the app wires them, STOP and ask the user — do NOT fall back to raw ORM.

Hook-level enforcement

When you write autonoma/.endpoint-implemented at the end of this step, the plugin’s validator hook parses entity-audit.md, opens the handler you named in the sentinel body, and blocks the write if any factory for a independently_created: true model contains an inline ORM write (prisma.<m>.create, db.<m>.create, tx.insert(<m>Table), etc.) or if any such model has no factory at all. The agent’s self-policed Step A–D check is backed up by this mechanical gate — if you try to ship the anti-pattern, the sentinel write fails with an itemised list of violations and you must fix them before advancing.

3.0 — Per-model decision tree (run this BEFORE writing any factory)

For every model with independently_created: true in autonoma/entity-audit.md, walk this tree in order. There is no “give up and use db.<model>.create()” escape hatch — db.<model>.create() inside a factory body for a independently_created: true model is NEVER acceptable.

Branch 1 — needs_extraction: true. The creation logic is inline in a route handler, a framework hook (Better Auth databaseHooks, NextAuth callbacks, Express closures), or an anonymous closure. Extract it first:

1. Move the inline block into a new named, exported function in a nearby module (*.service.ts, *.repository.ts, create-<model>.ts, or an existing service). Take a plain input object (no req/res/ctx), return the created record, preserve every side effect the inline block had.
2. Replace the inline block with a call to the new function. Real HTTP callers’ behavior must stay identical. Run typecheck/tests.
3. Update autonoma/entity-audit.md in-place: add an extracted_to: <new-path> field pointing at the file you created, and keep creation_file, creation_function, and needs_extraction: true exactly as Step 2 recorded them. The fidelity rubric’s framework-hook carve-out (Criterion 1) relies on those fields remaining intact so it can score the factory against the extracted helper rather than the un-callable hook.
4. Import the new function in the factory.

If extraction is genuinely impossible (inline block inseparable from req/res, or generated code), STOP and ask the user. Do NOT fall back to raw ORM.

Concrete example — Better Auth databaseHooks: if the audit flags User with needs_extraction: true pointing at src/auth.ts#buildAuth (databaseHooks.user.create), the closure body writes db.user.create, then ensureOrgMembership, then provisions a BillingCustomer. Calling db.user.create() in the factory silently skips every sibling row. Extract the closure into export async function createUserWithOnboarding(input), call it from the hook (production still works), update the audit, then import it in the factory.

Branch 2 — independently_created: true, no needs_extraction. Import and call the named export. See the DI playbook below for how to invoke it.

Branch 3 — independently_created: false. Register a factory whose create is a thin repository / ORM call. There is no SQL fallback.

3.0.1 — DI / constructor-injection playbook

Factories receive (data, ctx) where data is the value parsed by inputSchema / input_model. The DB client/transaction is whatever singleton your app already exports — import it directly. Walk this list in order; first match wins:

1. Top-level exported function — import { createX } from "..."; return createX(data);. Simplest case.
2. Static method — return XService.create(data, db); where db is the app’s exported DB client.
3. Instance method, needs only a DB client — const svc = new XService(db); return svc.create(data);.
4. Instance method, needs more dependencies (logger, event bus, config, clients) — find the app’s composition root (DI container, container.ts, app.module.ts, services/index.ts). Either import the already-constructed singleton (import { userService } from "@/services") or rebuild the service the way the composition root does, importing real singletons for everything (DB client, logger, event bus, temporal client). Do not invent mocks.
5. Impossible — STOP and ask the user. Do NOT inline ORM writes that bypass production logic.

Never mock, stub, or fake a dependency. The factory must exercise real code.

3.0.2 — External side effects policy

Audited creation functions often perform side effects beyond the DB row: Temporal workflows, GitHub/Stripe/Slack APIs, emails, analytics, LLMs. Your goal is correct DB state, not production-grade external delivery. Preserve every DB write (including writes to sibling tables done by ORM hooks, framework hooks, triggers). Order of preference:

1. Call the real function with real side effects if the test environment has sandbox keys / local Temporal / mocked SDKs wired.
2. Use the app’s existing test-mode toggle (NODE_ENV=test, DISABLE_WORKFLOWS=1, feature flag, null-object client).
3. Wrap external-only calls in try/catch inside the real function (not inside a rewritten factory body) — only for calls whose failure does not affect DB state under test.
4. Reimplement the DB writes inline. NEVER. If you’re typing db.<other_model>.create inside a factory to replicate what a hook would have done, the function wasn’t truly called — you re-wrote it. Go back to option 1 or 2, or ask the user.

You are NOT allowed to skip: password hashing, slug generation, normalization (pure CPU inside the creation function), DB writes performed by ORM/framework hooks on the created model (e.g. Better Auth’s databaseHooks.user.create writing Organization/Member/BillingCustomer), or writes to sibling tables the creation function itself performs (e.g. createProject writing a default Folder).

3.1 — Install SDK packages

TypeScript:

pnpm add @autonoma-ai/sdk @autonoma-ai/server-[framework] zod

Python:

pip install autonoma-ai

3.2 — Create the endpoint handler

Write a single handler file that:

1. Sets scopeField: "<your scope field>" plus the two secrets on the handler config. There is no executor field anymore.
2. Registers a factory for every model in entity-audit.md. Each factory:
   • Declares an inputSchema (Zod) / input_model (Pydantic) covering every field the dashboard sends. The SDK reads it for discover and validates payloads through it before invoking create.
   • For independently_created: true: imports the function from the audit’s creation_file and calls it inside create. Never reimplement the creation logic with an inline ORM call (see WRONG/RIGHT example below). For methods on a class, instantiate the class using the app’s exported DB client.
   • For independently_created: false: makes a thin repository / ORM call from inside create.
   • Optionally declares a teardown to remove the record during down.
3. Implements the auth callback using the app’s real session/token creation.
4. Passes both secrets from environment variables.

Follow the project’s existing code patterns — import style, file organization, error handling.

3.3 — Register the route

Add the endpoint to the app’s routing (e.g., app.post('/api/autonoma', handler)).

3.4 — Set up environment variables

Add AUTONOMA_SHARED_SECRET and AUTONOMA_SIGNING_SECRET to .env (or equivalent). If .env.example exists, add placeholders there too.

3.5 — The trap: inline ORM calls inside factories

The most common mistake is writing db.x.create({...}) inside a factory because calling the real function is inconvenient (constructor args, DI). That silently bypasses every piece of business logic the user has — or will add — and makes the scenario data diverge from what the app itself would produce.

// entity-audit.md: creation_function = OnboardingManager.getState
// WRONG — inline ORM, bypasses OnboardingManager entirely
OnboardingState: defineFactory({
  inputSchema: z.object({ applicationId: z.string() }),
  create: async (data) => {
    return db.onboardingState.create({ data: { applicationId: data.applicationId, step: "welcome" } });
  },
}),

// RIGHT — import the real DB client, instantiate the class, call the real method.
// `data` is inferred from `inputSchema` — no z.infer<...> annotation needed.
import { db } from "@/db";
import { OnboardingManager } from "@/lib/onboarding-manager";

OnboardingState: defineFactory({
  inputSchema: z.object({ applicationId: z.string() }),
  create: async (data) => {
    const manager = new OnboardingManager(db);
    return manager.getState(data.applicationId);
  },
}),

The factory imports the same db (or prisma/drizzle/session) singleton the rest of the app uses. The SDK does not own a connection — your factory writes through whatever path your app’s services normally take.

defineFactory is generic over its inputSchema and optional refSchema, so data and (when set) record are typed automatically. Add refSchema: z.object({ id: z.string() }) whenever you also write a teardown and want a typed record.

Phase 4: Smoke test and factory-integrity check

This phase proves the handler was wired correctly. It does not run the full up/down lifecycle — that is Step 5’s job.

4.1 — Start the dev server

Check if it’s already running. If not, start it.

4.2 — Test discover

BODY='{"action":"discover"}'
SIG=$(echo -n "$BODY" | openssl dgst -sha256 -hmac "$AUTONOMA_SHARED_SECRET" | sed 's/.*= //')
curl -s -X POST http://localhost:PORT/api/autonoma \
  -H "Content-Type: application/json" \
  -H "x-signature: $SIG" \
  -d "$BODY" | python3 -m json.tool

Expected: JSON with schema containing models, edges, relations, scopeField. Every model from entity-audit.md must appear under schema.models. edges and relations are emitted as empty arrays — the dashboard accepts that, and the _alias/_ref graph in the create payload carries equivalent dependency information at request time.

4.3 — Factory-integrity check

Before completing this step, prove deterministically that every factory you registered actually calls the audit’s creation_function:

1. Re-read entity-audit.md. List every model with independently_created: true and its creation_file / creation_function. If any entry still has needs_extraction: true, make sure it also has extracted_to: <path> pointing at the extracted helper you created per Branch 1 — that’s what the factory must import and call. A bare needs_extraction: true with no extracted_to means you skipped the extraction step; HALT and extract.
2. For each such model, open the handler file and verify BOTH:
   • an import line pulls in creation_function (or the class that owns it) from a path that resolves to creation_file
   • the defineFactory({ create }) body invokes that symbol (e.g. manager.getState(...), createUser(...), ProjectService.create(...))
3. Spot-check with grep — any inline ORM create inside a factory for a model marked independently_created: true is the anti-pattern:

   grep -nE '(prisma|db|tx)\.[a-zA-Z]+\.create\(' <handler-file>

   Cross-reference each match against the audit; replace inline calls with the real function before continuing.

If any factory fails this check, fix it before reporting success. The full lifecycle validation in Step 5 will otherwise find it the hard way.

Phase 5: Report

Tell the user:

“Done! I’ve set up the Autonoma SDK at [endpoint path].

Packages installed: [list] Factories registered (from entity-audit.md): [list each model + the creation_file#creation_function it calls (or the repository call for independently_created: false) + side effects observed] Auth: [how sessions/tokens are created]

Smoke test: discover returns schema with [N] models; factory-integrity check passed for [N] factories.

Next steps:

1. Set your secrets in .env:

   AUTONOMA_SHARED_SECRET=<your-value>
   AUTONOMA_SIGNING_SECRET=<your-value>

2. Proceed to Step 5 to validate the full up/down lifecycle against every scenario.
3. When ready, paste AUTONOMA_SHARED_SECRET into the Autonoma dashboard.”

Important reminders

• Never create a standalone server or sidecar. Always integrate into the backend you identified in Phase 1.1. If that’s not possible, stop and ask the user — do not invent a workaround.
• SDK language must match backend language. Do not install autonoma-ai (Python) into a TypeScript/NestJS project, etc.
• Do not scaffold at the repo root when a backend directory exists, including non-standard names like core-app-backend/, apps/api/, services/core/.
• Always read the live docs at https://docs.agent.autonoma.app/llms.txt before implementing. The SDK may have been updated.
• ALL database writes go through the SDK endpoint. Never write directly via psql, raw SQL, or ORM methods.
• Register a factory for every model in the entity audit — there is no SQL fallback. For independently_created: true rows the factory must call the audit’s identified function; for independently_created: false rows a thin repository call is fine. Never reimplement an identified creation function inline.
• Validate is Step 5’s job. This step only runs discover plus the factory-integrity check. Do not try to run up/down here.
• Match existing codebase patterns. Don’t introduce new conventions. Use the same import style, file organization, and error handling.
• Use testRunId in all unique fields (emails, slugs, org names) to prevent parallel test collisions.
• If context compaction occurs, re-read this prompt and use a TODO list to track progress.
