Design GraphQL schemas: type design, N+1 prevention, pagination patterns, mutation design, and schema evolution.

Design statistically rigorous A/B tests: hypothesis formation, sample size calculation, metric selection, and guardrail setup.

Design event-driven systems: event schema design, broker selection, idempotency, ordering guarantees, and event sourcing.

Audit error handling across a codebase: unhandled rejections, swallowed exceptions, missing retries, and inconsistent error types.

Use before running untrusted or model-generated code, installs, or binaries: stand up a disposable, network-restricted sandbox, run it, then tear it down.

Use when deploying or operating apps on DigitalOcean App Platform and Managed Databases: app specs, secrets, PRE_DEPLOY migrations, domains, scaling, cost.

Design and implement design systems: token architecture, component APIs, documentation patterns, and governance.

Manage API and feature deprecations safely: sunset timelines, migration guides, usage tracking, and forced upgrade paths.

Find and safely remove dead code: unreachable branches, unused exports, orphaned files, and stale configuration.

Design data governance frameworks: data classification, lineage tracking, access policies, retention, and compliance mapping.

Design ergonomic component APIs: prop design, composition patterns, accessibility defaults, and forward compatibility.

Conduct systematic competitor analysis: feature matrices, positioning maps, moat assessment, and strategic gap identification.

Use when reviewing a diff, PR, or staged changes: a five-pass protocol that yields severity-ranked findings with concrete failure cases.

Create comprehensive onboarding documentation for any codebase: architecture maps, data flow diagrams, and gotchas for new developers.

Analyze customer churn: cohort analysis, churn signals, at-risk scoring, retention experiments, and win-back strategies.

Invoke when building or tuning a RAG/semantic-search pipeline's chunking: pick strategy, chunk size, and overlap validated against retrieval metrics.

Design rate limiting strategies for APIs: token bucket, sliding window, per-user limits, and 429 response patterns.

Design API products: endpoint design for developer experience, versioning strategy, rate tiers, and ecosystem growth.

Use when API reference docs must be generated or updated from source code, with verified schemas, runnable examples, and complete error catalogs.

Generate and run contract tests for REST and GraphQL APIs from OpenAPI specs or schema definitions.

Design cohesive animation systems: motion principles, timing curves, choreography rules, and accessible motion.

Manage AI agent products: capability roadmaps, eval-driven development, safety reviews, user trust, and launch criteria.

Use to scan agent transcripts, traces, and telemetry for leaked secrets or PII before they are stored or shared, and to fix the root cause.

Design accessibility programs: WCAG compliance, assistive tech support, testing workflows, and disability inclusion.
