“PR”

Code Generation from Issue/PRD

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

Performance Profiling & Optimization Coach

Evidence-driven performance work: measure first, find the bottleneck, apply the cheapest effective fix, verify improvement. Works for CPU/memory/IO.

Pair-Programmer for an Unfamiliar Codebase

Onboarding/exploration prompt: builds an accurate mental model of unknown code, tracing one request end to end before changing anything.

Property-Based Test Designer

Finds invariants and writes property-based tests (Hypothesis/fast-check) that discover edge cases humans miss.

ML Problem Framing & Baseline Designer

Before modeling: defines the business problem, label, metrics, baselines, and data requirements — prevents solving the wrong problem with a fancy model.

Prompt/Template CI & Regression Harness Builder

Productionizes prompt changes: versioned prompts, offline eval gates, online shadows, and rollback — prompt-as-code.

Data Governance / Privacy Engineering (GDPR)

Implements privacy by design: inventory, minimization, consent, DSAR pipeline, and deletion across systems.

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

Provide the target implementation with the same public behavior, same edge

Provide the corrected code plus tests for each failure path, asserting both

Target architecture: in-process module first (seams, interfaces), then optional

Strangler steps as independently shippable PRs with feature flags, metrics for

Technical Debt Prioritization Facilitator

Converts vague "tech debt" complaints into a ranked, quantified backlog linked to business risk and remediation cost.

Feature Flag / Progressive Delivery Planner

Safe rollout system: flag lifecycle, targeting, kill switches, experimentation guardrails, and cleanup.

File Export / Import & CSV Processing

Robust bulk data in/out: streaming, validation, error reports, huge files, encoding issues, and idempotent upserts.

Progressive Web App / Offline Sync Engineer

Offline-capable web apps: service worker caching strategy, conflict resolution, background sync, and update UX.
