Emergency fix-and-deploy pipeline — diagnose a bug, apply a minimal fix, verify safety, deploy to production, and confirm the service is healthy. Supports Vercel, AWS, Railway, Fly.io, Heroku, and Kubernetes. Tracks incident timeline and MTTR. Triggered by 'fix and deploy', 'hotfix and ship', 'emergency fix', 'fix this bug and deploy', 'patch and push', 'fix and ship'.

Automated app improvement cycles. Assesses each app's health, prioritizes by staleness and debt, consumes recall/metrics/evolve findings from cron, then runs targeted fix pipelines per app. Fully autonomous — runs unattended via cron or manually. Triggers: tend my apps, improve my apps, app maintenance, run improvement cycle, garden, maintain apps.

Profile and audit mobile app performance -- cold/warm/hot startup time, memory leaks, battery drain, network efficiency, frame rate jank, and binary size. Covers Flutter, React Native, Swift, and Kotlin apps. Detects image memory issues, undisposed controllers, polling without backoff, missing virtualized lists, and unused asset bloat. Use when diagnosing slow launches, investigating ANRs, reducin

Analyze manufacturing defect detection and quality control systems — computer vision inspection pipelines, SPC control charts, Six Sigma process capability (Cp/Cpk), defect classification taxonomies, root cause analysis tooling, and measurement system analysis. Audit QC codebases for detection accuracy, false reject rates, statistical rigor, and traceability compliance.

Audit adaptive learning and student personalization systems for pedagogical quality. Use when you need to evaluate learning path algorithms (branching, remediation, acceleration), mastery detection models (Bayesian, IRT, threshold-based), knowledge graph prerequisite accuracy, recommendation engine fairness and bias, spaced repetition and interleaving, WCAG 2.1 AA and Section 508 accessibility com

Audits and implements mandatory image resizing and compression for all uploaded user images to reduce storage costs while preserving visual quality.

Statically scan a CSS / single-file HTML / multi-file frontend project for references to undefined CSS custom properties — the silent class of bug where `color: var(--ink-2)` is written but `--ink-2` is never declared in any `:root { ... }` block, and the text renders invisible because `var()` with no fallback resolves to the unset initial value. TRIGGER this skill whenever the user says any of: "

Audit a tenant management system for eviction prevention and risk prediction. Evaluates payment pattern analysis and arrears tracking, early warning indicators (financial, behavioral, external), intervention trigger automation, pre-filing mediation workflows, emergency rental assistance integration (ERAP, LIHEAP), legal process tracking with jurisdiction-specific compliance (VAWA, SCRA), and outco

Analyze behavioral segmentation systems for RFM scoring, cohort tracking, churn propensity, engagement scoring, persona clustering, and journey mapping using behavioral economics frameworks. USE THIS SKILL WHEN: user mentions customer segmentation, RFM analysis, cohort analysis, churn prediction, engagement scoring, customer personas, journey mapping, retention analysis, customer lifetime value, o

Generate integration tests for APIs, databases, and external services. Auto-detects backend stack (Express, Fastify, NestJS, Django, FastAPI, Rails, Go), ORM (Prisma, TypeORM, SQLAlchemy, GORM), and database (PostgreSQL, MongoDB, Firestore), then creates tests covering endpoint CRUD, auth flows, DB transactions, and external service failures with proper fixtures and mocks. Self-heals failing tests

Feature discovery agent — mines project docs, memory, user feedback, and competitor gaps to surface the highest-leverage features to build next. Outputs a prioritized feature backlog.

Full-stack app pipeline — build, test, review, and deploy across one or ALL repos. Scans CLAUDE.md, MEMORY.md, TODOs, open PRs, and issues for shippable work. Supports 'ship all' for multi-repo. Use when: 'build and ship', 'ship it', 'ship all', 'deploy everything', 'full pipeline', 'what needs shipping', 'end to end'.
