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)

Polyglot Translation Between Stacks

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

Summarize behavior and identify semantic pitfalls in translation:

Map source constructs to target idioms (error values→exceptions/Result,

Staff-Engineer Pull Request Review

A rigorous, prioritized PR review that distinguishes blockers from nits and checks correctness, security, concurrency, and maintainability — like a senior reviewer.

Security-First Code Audit

OWASP-oriented security review for a module or whole PR. Produces exploit scenarios and fixes ordered by severity (CVSS-like).

Root-Cause Analysis (5 Whys / Blameless Postmortem)

Runs a blameless postmortem for an incident: timeline, root causes, contributing factors, and durable system fixes — not human blame.

Refactoring Planner (Safe, Incremental)

Before changing tangled code: identifies seams, sequences refactor steps that keep tests green at every commit, and prevents "rewrite everything" disasters.

God Class / Spaghetti Decomposer

Takes one oversized class/file and produces a concrete extraction plan + first extraction fully coded with tests.

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.

Memory Leak / Resource Leak Hunter

Diagnoses leaks (heap growth, fds, connections) methodically with tool-specific steps for the runtime.

Concurrency Bug / Race Condition Investigator

Finds and fixes race conditions, deadlocks, and ordering bugs by constructing interleavings, with deterministic tests.

Flaky Test Eliminator

Diagnoses flaky tests by category (async timing, order dependence, shared state, date/randomness) and gives deterministic fixes.

Dependency Upgrade / Breaking-Change Migrator

Safely upgrades libraries/frameworks across major versions with a diff of breaking changes, codemods, and verification.

Dead Code / Architecture Decay Analyst

Finds genuinely unused code and accidental coupling using evidence, avoiding deletion of reflection/DI/routed entry points.

Exception/Error-Handling Reviewer

Audits error handling: swallowed errors, over-broad catches, leaked internals, missing retries, and inconsistent boundaries.

Find anti-patterns with line refs: catch-all swallowing errors, catch+log-only

Design the error boundary: domain exceptions mapped to transport codes,
