Purpose: This document guides any AI coding agent (Kiro, Cursor, Antigravity, Copilot) on how to build, test, and ship changes to the Agent_in BI platform. Follow these instructions exactly. No shortcuts. No gaps.
Two caveats for anyone reading this from the public repository.
- The
.kiro/specs/tree referenced throughout is not part of this repository — it is gitignored and lives only on the original author's machine. Sections below that instruct you to read or tick a spec file describe the process that was used during development; you will not find those files here.- This document describes the intended end state, not the current one. It is written in the aspirational voice of a build plan ("what this becomes"), and several things it names are targets rather than shipped facts. For what is actually built, tested, and running, read
README.md, which is deliberately scoped to verifiable claims.
What this is: A multi-agent Business Intelligence platform that takes business prompts and produces comprehensive Go-To-Market strategy reports using 7 specialized AI agents (Orchestrator, Research, Strategy, Critic, Planner, QA, Memory).
What it becomes: A production-grade, enterprise-ready, customer-facing SaaS application with:
- Scale-to-zero infrastructure — $0 cost when nobody is using it
- Enterprise multi-tenancy — data isolation at the database level
- Custom payments — Stripe + UPI, subscription billing
- Modern frontend — Next.js on Vercel with glassmorphism design
- Durable workflows — Inngest replacing Celery + Redis
NEVER write code without a spec. Every change follows this sequence:
1. REQUIREMENTS → What must the system do? (acceptance criteria)
2. DESIGN → How will the system do it? (interfaces, data models, architecture)
3. TASKS → What steps to implement? (ordered, with dependencies)
4. CODE → Build it (following the design exactly)
5. TEST → Verify it (LHS three-tier testing)
6. VERIFY → Confirm it (integration tests, cold start tests)

| Concern | Choice | Reason |
|---|---|---|
| Backend Framework | FastAPI + Uvicorn | Async ASGI, auto OpenAPI docs, Pydantic validation — already in use |
| Frontend Framework | Next.js 14+ (App Router, TypeScript) | SSR/SSG, edge deployment, React ecosystem |
| Frontend Hosting | Vercel | Edge CDN, preview deploys, zero-config, free tier |
| Backend Hosting | Google Cloud Run (intended target — nothing currently deployed) | Scale-to-zero, per-request billing, container-based. A service (agent-in-api, project gen-lang-client-0777740340, region asia-south1) was deployed previously and has been torn down. IaC: cloudrun-service.yaml; runbook: deploy/cloudrun-deploy.md. (render.yaml is deprecated/non-canonical.) |
| Database | Supabase PostgreSQL (or Neon) | Scale-to-zero, pgvector, RLS, Auth built-in, free tier |
| Vector Storage | pgvector (in PostgreSQL) | Eliminates ChromaDB, single database, RLS-protected |
| Async Workflows | Inngest | Durable functions, event-driven, zero-cost idle, step-level retry |
| Authentication | Supabase Auth | OAuth (Google/GitHub), anonymous sessions, JWT, free tier |
| Payments | Stripe (Payment Intents API + UPI) | Custom flow, PCI compliant, UPI support, global coverage. Stripe MCP server available for direct API operations |
| Observability | Langfuse + structlog + OpenTelemetry | LLM-specific metrics, distributed tracing, structured logs |
| Testing | pytest + LHS methodology | Three-tier classification from Project 3000 |
| Linting | ruff | Fast Python linter, replaces flake8 + isort |
| Type Checking | mypy (strict) | Catch bugs at compile time |
| CI/CD | GitHub Actions | Free for public repos, integrated with Vercel |
EVERY test file MUST follow the three-tier classification. No exceptions.
Standard inputs that verify expected behavior. These tests MUST always pass.

]When testing security punctures, ALWAYS check that hostile payloads are NOT echoed back in responses:
# BAD — payload passes through unsanitized
assert "OR '1'='1" not in response.text
assert "<script>" not in response.text
assert "\x00" not in response.text- Type hints everywhere — all function signatures, return types, and class attributes
- Pydantic for all data contracts — request/response models, config, internal DTOs
- async/await by default — all database queries, HTTP calls, LLM invocations
- Dependency injection — use FastAPI's
Depends()for auth, tenant context, rate limiting, database sessions - No bare exceptions — always catch specific exception types
- Structured logging — use
structlogwith context bindings (job_id, user_id, agent_role) - Docstrings — every public function and class gets a docstring explaining purpose, args, returns
- Constants over magic values — define limits, timeouts, retry counts as named constants
- Maximum function length — 50 lines. If longer, decompose.
- No print statements — use logger
- Strict TypeScript —
strict: truein tsconfig.json, noanytypes - React Server Components by default — use
'use client'only when needed (interactivity, hooks) - CSS Modules for styling — no inline styles, no Tailwind (unless explicitly requested). All styles via
.module.cssfiles - Design tokens from
tokens.ts— never hardcode colors, spacing, or fonts. Usetokens.colors.primary[500], not'#8b7cf6' - Font roles are strict — DM Sans for UI/navigation/labels, Source Serif 4 for agent output/reports, JetBrains Mono for code/logs. No mixing.
- Error boundaries — wrap every page-level component
- Loading states — skeleton screens for every async data fetch
- Accessibility — ARIA labels on all interactive elements, semantic HTML
- Pretext for virtualized text only — use
pretextlibrary in<LogStream>and<WorkflowDAG>components for DOM-free text measurement. Do NOT use Pretext for static pages, forms, or billing UI. - Theme support — all components must work in both dark and light modes via CSS custom properties. Never hardcode theme-specific colors.

- DO NOT add Redis or any always-on service. Everything must scale to zero.
- DO NOT store sensitive payment data in the application database. Use Stripe's servers.
- DO NOT rely on in-memory state between requests. Serverless functions are ephemeral.
- DO NOT use application-level WHERE clauses for tenant isolation. Use RLS policies.
- DO NOT skip the Critic Agent evaluation step. ALL strategic outputs must pass through it.
- DO NOT create infinite retry loops. Bounded retries only (max 1 for Critic, max 20 total steps).
- DO NOT hardcode LLM model names in agent code. Use the LLM Router.
- DO NOT use
print(). Usestructloglogger. - DO NOT create test files without all three LHS tiers.
- DO NOT merge code without passing
ruff check .andmypy app/ --strict. - DO NOT use Tailwind CSS unless explicitly requested by the user.
- DO NOT use inline styles in React components. Use CSS Modules + design tokens.
- DO NOT skip skeleton screens. Every async data fetch needs a loading state.
- DO NOT deploy without verifying cold start time is under 3 seconds.
- DO NOT use pure black (#000000) for backgrounds. Use warm near-black (#1a1a1a) to prevent halation.
- DO NOT use font weight 300 (light) in dark mode. Minimum weight is 400 (regular).
- DO NOT use saturated accent colors (e.g., #6c63ff). Use desaturated variants (#8b7cf6) to prevent vibration on dark backgrounds.
- DO NOT apply glassmorphism (backdrop-filter) to full-page backgrounds or large surfaces. Reserve for cards and modals only.
- DO NOT hardcode 'dark' or 'light' theme values. Use CSS custom properties that switch automatically based on theme mode.
- DO NOT use Inter, Roboto, or Arial as primary fonts. The design system mandates DM Sans (UI), Source Serif 4 (reading), JetBrains Mono (code).
- DO NOT modify design.md, requirements.md, or design_system tokens after approval. Only tasks.md checkboxes may be updated during execution.

fetch_stripe_resources |
List/fetch any Stripe resource | Any |
Generic API Access (for ANY Stripe operation):
| Tool | Purpose | Task |
|---|---|---|
stripe_api_search |
Find any Stripe API operation by keyword | Any |
stripe_api_details |
Get full parameter details for an operation | Any |
stripe_api_execute |
Execute ANY Stripe API call (with human confirmation for writes) | Any |
Documentation & Planning:
| Tool | Purpose | Task |
|---|---|---|
search_stripe_documentation |
Search Stripe docs | Any |
stripe_integration_recommender |
Get integration planning guidance | 3.2 (initial setup) |
Phase 3 — Task 3.2 (Billing API Endpoints):
1. Use `stripe_integration_recommender` to validate the Payment Intents + Subscription architecture
2. Use `stripe_api_search` to find exact API operation IDs for PaymentIntent, Subscription, Customer
3. Use `stripe_api_details` to get full parameter schemas for each operation
4. Implement Python service code using the `stripe` pip package (NOT the MCP server)
5. Use MCP tools for verification: `fetch_stripe_resources` to confirm resources were created correctly
Phase 3 — Task 3.3 (Webhook Handler):
1. Use `search_stripe_documentation` to find webhook event schemas
2. Use `stripe_api_search` for webhook endpoint registration API
3. Implement webhook handler using `stripe` pip package with signature verification
4. Use `stripe_api_execute` to register webhook endpoint URL
Phase 6 — Task 6.1 (Configure Stripe Products & Prices):
1. Use `create_product` to create "Standard Plan" and "Enterprise Plan" products
2. Use `create_price` to create monthly and annual prices for each product:
- Standard Monthly: ₹999/month (99900 paisa)
- Standard Annual: ₹9,999/year (999900 paisa)
- Enterprise Monthly: ₹4,999/month (499900 paisa)
- Enterprise Annual: ₹49,999/year (4999900 paisa)
3. Store returned product IDs and price IDs in environment variables
4. Use `fetch_stripe_resources` to verify all products and prices are correct
Phase 6 — Task 6.2 (End-to-End Payment Flow):
1. Use `stripe_api_search` for "create payment intent" to get operation details
2. Use `create_customer` to test customer creation flow
3. Use `stripe_api_execute` with "GetPaymentIntents" to verify test payments
4. Use `search_stripe_resources` to audit customer-subscription mappings
- MCP for infrastructure, SDK for application code: Use MCP tools to CREATE and VERIFY Stripe resources. Use the
stripePython pip package in the actual application code. - Live mode caution: The Stripe account is in LIVE mode. The
stripe_api_executetool requires human confirmation for write operations — this is a safety feature. - Never store Stripe secrets via MCP: Environment variables and secrets are managed through
.envfiles, not MCP tools. - Neon MCP for schema operations: Use
mcp-server-neonfor database branching, schema comparison, and migration testing — not for application queries. - Cloud Run MCP for deployment: Use
cloudrunMCP only during Phase 3 deployment, not during local development. - Inngest MCP for workflow testing: Use the
inngestMCP server tools (once the local Inngest Dev Server is started vianpx inngest-cli@latest devornpx inngest@latest dev) to inspect and trigger durable workflow functions during Phase 4.
| Tool | Purpose | When |
|---|---|---|
run_sql |
Execute SQL directly (migrations, debugging) | Any phase |
describe_table_schema |
Inspect table structure | Verify migrations |
get_database_tables |
