Once root cause is confirmed: minimal fix, why it's correct, blast radius,

Regular Expression / Parser Generator

Builds correct, readable regexes with test matrices instead of cryptic one-liners; prefers real parsers when regex is the wrong tool.

The regex for {{flavor: PCRE/JS/Python RE2}} with the x/verbose mode and

Anchoring rules, Unicode handling, catastrophic-backtracking analysis, and

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.

List failure modes: duplicate delivery, at-least-once, lost ack, poison message,

Choose the concurrency primitives and justify vs alternatives:

Define retry/backoff/jitter, DLQ policy, and visibility timeout math.

Microservice / Event-Driven System Coder

Scaffolds an event-driven service with outbox, schema registry, contracts, and observability — keeps services loosely coupled.

gRPC / Protobuf API Builder

Defines versioned protobuf contracts, streaming RPCs, error model, and generates client/server stubs with interceptors.

Mobile (iOS/Android/Flutter) Feature Coder

Generates a mobile screen/feature with offline support, lifecycle correctness, and platform conventions.

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

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

CI/CD Pipeline Engineer

Creates secure, fast pipelines: caching, matrix tests, SBOM, signing, progressive delivery, and rollback.

Code Generation from Issue/PRD

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

Acceptance criteria in Gherkin (Given/When/Then) — every PRD claim traced to

Technical design: architecture sketch (ASCII), data model changes, API

Task breakdown: small (<1 day) tickets with title, acceptance criteria, files

Test plan (unit/integration/E2E mapping to ACs), rollout plan (flag → % rollout

Then implement the foundation layer (models + migration + contract + validation)
