Development setup often takes too long and leaves new contributors blocked. This skill helps Claude, Codex, and Claude Code design setup guides, scripts, shortcuts, and tooling improvements.

Errors and incidents are hard to triage when evidence is spread across logs, stack traces, and services. This skill structures diagnosis, parses logs, identifies patterns, and guides minimal fixes.

Unused imports, functions, and classes increase maintenance cost and deployment size. This skill guides Claude, Codex, and Claude Code through conservative analysis, backups, removal, and validation.

CLI commands often grow inconsistent, unclear, or hard to maintain. This skill helps Claude, Codex, and Claude Code design usable commands, arguments, error handling, and documentation.

Developers often lose time tracing why code exists and what depends on it. This skill prompts Claude, Codex, or Claude Code to gather related graph knowledge, callers, imports, and tests before changes.

AI coding sessions can leave redundant comments, defensive checks, type casts, and inconsistent style. This skill guides focused cleanup that preserves behavior and verifies changes.

Teams need stable identifiers that work across services and databases. This skill explains UUID v4 and v7 usage with TypeScript examples.

Fullscreen UI work can be fragile across browsers and Angular components. This skill provides screenfull patterns for toggles, viewers, dashboards, and presentation modes.

Angular teams often struggle to choose the right RxJS operator and cleanup pattern. This skill gives practical patterns for reactive data flows, Signals interop, and error handling.

Enterprise Angular teams need consistent ng-alain components. This skill guides table, form, ACL, layout, theming, and accessibility patterns.

Angular teams often repeat data formatting, cloning, grouping, and browser helper logic. This skill shows how to use @delon/util helpers in ng-alain and task workflow components.

Teams need consistent Angular forms with validation, layout, and async options. This skill guides Claude, Codex, and Claude Code through @delon/form patterns.

Angular teams need consistent charts that match ng-alain dashboard patterns. This skill provides @delon/chart examples and guidance for common enterprise visualizations.

Angular apps often repeat API requests and recompute data without a cache plan. This skill guides memory, session, LocalStorage, and HTTP caching with @delon/cache.

Angular modules often need shared updates without tight coupling. This skill guides BlueprintEventBus events, subscriptions, lifecycle cleanup, and workflow coordination.

Angular teams need consistent patterns for CDK interactions. This skill gives reusable guidance for drag-drop, overlays, virtual scrolling, clipboard, accessibility, and platform detection.

Angular teams need consistent standalone components that follow current framework patterns. This skill guides Claude, Codex, and Claude Code to generate components with signals, modern templates, and clean service integration.

FigJam plugin development can fail when the CLI, WebSocket server, and plugin consoles disagree. This skill gives a focused checklist for diagnosing connection, sync, and patch problems.

Core DSL changes can break validation, normalization, diffing, and patch behavior. This skill gives Claude, Codex, and Claude Code a focused workflow for safe core package updates.

Prompt changes can silently reduce output quality. This skill builds golden datasets, runs Promptfoo evaluations, and summarizes failures and recent trends.
