Async Python code can leak sessions, block responses, and deadlock under load. This skill gives FastAPI and SQLAlchemy patterns for safer async database work.

Alembic autogenerate can create migrations that lose data or lock tables. This skill gives practical PostgreSQL patterns for safer schema changes, reviews, testing, and production rollout.

Slow database queries harm application reliability and scale. This skill gives practical PostgreSQL patterns for faster queries, safer migrations, and clearer monitoring.

PostgreSQL migrations can pass tests while causing locks, slow scans, or index bloat. This skill gives Claude, Codex, and Claude Code practical patterns for safer schema and query review.

iOS release work for Expo apps requires EAS profiles, credentials, TestFlight steps, and version rules. This skill gives focused checklists and commands for build, submit, OTA updates, and troubleshooting.

Expo apps often hide broken API flows, unsafe token handling, and stale screen data. This skill guides Claude, Codex, or Claude Code through a structured API audit.

React interfaces often fail to show clear loading, error, empty, and submission states. This skill gives practical patterns for predictable async UI behavior.

GraphQL client work often creates duplicate operations, weak error handling, and stale generated types. This skill guides consistent .gql files, Apollo generated hooks, codegen steps, and mutation UI safeguards.

Formik forms often repeat validation, error display, and submit-state logic. This skill provides concise patterns for reusable fields, Yup schemas, GraphQL submissions, edit forms, and multi-step flows.

Large repositories can overwhelm code exploration and consume limited context. This skill builds a local symbol index so you can retrieve targeted code and preserve project knowledge.

Large repositories make symbol lookup slow and repetitive. This skill adds repo-map MCP tools that index project symbols and retrieve relevant code context quickly.

Store teams need a reliable way to format and route thermal print jobs. This skill documents printer setup, connectivity checks, immediate printing, and scheduled jobs.

Preparing molecular dynamics starting structures requires precise Packmol syntax and geometry choices. This skill helps create inputs, solvation setups, interfaces, and validation steps for Packmol workflows.

AI coding sessions can skip requirements, design, or testing when pressure rises. This skill keeps work inside a strict waterfall flow with documented gates.

Teams lose project intent when requirements live only in chat or task lists. This skill keeps scope, tests, decisions, and progress in a persistent features.yml file.

Inconsistent commit messages make reviews and release notes harder to scan. This skill formats concise Conventional Commit summaries with clear 72-column bodies.

Remix apps need cache freshness without fragile invalidation logic. This skill guides Redis-backed caches, SSE revalidation, TTL choices, and tests.

Repeated workflow lessons can be lost or applied without enough evidence. This skill captures structured experiences and creates traceable proposals before durable guidance changes.

Security teams need structured ways to inventory authorized targets. This skill organizes reconnaissance phases, evidence capture, and reporting for controlled assessments.

Linux privilege escalation reviews require careful enumeration and strict authorization. This skill organizes common checks, risky vectors, and evidence capture for controlled labs and defensive audits.
