“EN-01-Code-Generation-Prompts”

Code Generation from Issue/PRD

Turns a product requirement into a shippable implementation plan + skeleton with acceptance criteria traceability. Useful at sprint start.

Infrastructure as Code (Terraform/Pulumi/Docker/K8s)

Produces reviewable IaC: modular, idempotent, least-privilege IAM, with state and rollout safety.

Legacy Code Modernization Engineer

Use when migrating old code (e.g. jQuery → React, Python 2 → 3, callbacks → async/await, class components → hooks) while preserving behavior exactly.

"Characterization": describe exactly what the current code does, including

Code wrapper with named groups and unit tests.

Concurrency & Distributed Systems Implementer

For locks, queues, idempotent workers, race conditions, and retries — forces correctness reasoning before code.

Polyglot Translation Between Stacks

Translates implementations across languages while preserving idioms, semantics, and gotchas (time zones, floats, concurrency, sorting) rather than line-by-line.

Senior Full-Stack Feature Builder

…complete, production-ready feature end to end (database schema, API, validation, frontend, tests). The prompt forces the model to ask clarifying questions first, plan before coding, and follow your team's stack.

Ask up to 8 clarifying questions about requirements, edge cases, auth rules,

Then produce a short technical plan: data model, API contract (method, path,

Function-Level Implementation with Strict Spec

Best for generating one well-tested function/module from a precise spec. The deliberate-questions-first pattern reduces hallucinated APIs.

Restate the contract and list 6-10 edge cases (empty input, duplicates,

Prove correctness with a brief argument, then provide a table-based test

Rewrite incrementally, keeping public function signatures stable where used

Provide a migration checklist and a strangler-fig rollout plan (feature flag

Include regression tests that encode CURRENT behavior BEFORE the rewrite

Python Production Script / CLI Generator

Generates a robust Python CLI with argparse, logging, retries, dry-run, and typed config — ideal for automation, data pipelines, and internal ops scripts.

React / Next.js Component + Page Builder

Builds accessible, typed React components with loading/error/empty states, server-client boundary decisions (Next.js App Router), and responsive styles.

REST API Designer + Implementer

Produces a consistent, versioned REST API: OpenAPI spec first, then implementation, auth, rate limits, idempotency, and docs. Great for new services.

GraphQL API & Resolver Builder

For designing GraphQL schemas without over-fetching pitfalls: pagination, dataloaders, auth in resolvers, n+1 prevention, and persisted queries.
