The library

code-reviewer · When you need systematic code review for bugs, security, and quality improvements.

palette-stylist · When you need cohesive, accessible color systems from reference images and vibes.

nutrient-metabolism · When you need detailed biochemistry of how your body processes specific nutrients.

cpp-pro · When you need expert C++ development with modern language features and optimizations.

nutrition-science-foundations · When you need foundational knowledge of how macronutrients, micronutrients, and digestion work.

csharp-developer · When building C# applications with clean architecture and async patterns.

chaos-engineering · Validating infrastructure resilience before production relies on a service.

database-optimizer · Diagnosing 100+ ms query latency when generic optimization doesn't pinpoint the bottleneck.

skillx_class_aware_c2__feature_engineering__SKILL · Preparing respondent-keyed data for difference-in-differences causal analysis.

incident-response · Coordinating response to SEV1/SEV2 incidents when multiple teams need synchronized action.

debugging-wizard · When stack traces don't immediately reveal the bug and multiple independent-seeming changes coincide.

monitoring-observability · Gaining the three pillars (logs/metrics/traces) when a single monitoring signal is insufficient.

devops-engineer · Automating build-test-deploy across environments when manual deployments risk inconsistency.

release-management · Minimizing blast radius when deploying high-traffic or stateful services.

django-expert · Scaffolding a production Django API with query optimization and permission constraints.

sre-patterns · When service reliability is ad-hoc and alert fatigue prevents visibility into true availability.

dotnet-core-expert · Scaffolding a .NET Core service when C# and strong typing are organizational standards.

constraint-drilling · Sharpening a broad research hypothesis into testable subclaims.

agent-orchestration · When multiple independent agents must coordinate on shared goals without central control.

embedded-systems · When embedded performance or power constraints demand hardware-aware firmware.

fleet-mission · When a fleet must execute synchronized, distributed behaviors toward a shared objective.

fastapi-expert · When a Python service needs sub-100ms latency and high concurrency that sync frameworks can't match.

gupp-propulsion · When vehicle efficiency or acceleration performance must be pushed beyond default calibrations.

feature-forge · When baseline model accuracy plateaus and feature engineering is the remaining leverage.

mayor-coordinator · When a project spans multiple teams and success requires explicit coordination, not just communication.

fine-tuning-expert · When zero-shot performance is inadequate but full training is too expensive.

notion-2 · Agents needing read-modify-append workflows on Notion databases without destructive rewrites.

polecat-worker · Single-task ephemeral agents that execute one bead to completion and terminate, never re-activate.

flutter-expert · Cross-platform mobile development where reusable const widgets and scoped state management (Riverpod) reduce rebuilds and improve frame rates.

runtime-hal · Multi-runtime agent frameworks needing uniform hook/GUPP semantics across Claude Code, Codex, Gemini, Cursor without editing skills.

fullstack-guardian · Teams building features across frontend, backend, and database that need security-first design avoiding common injection and timing attacks.

sling-dispatch · Orchestrating work across multiple ephemeral execution units where idempotent dispatch and crash recovery matter more than atomic transactions.

game-developer · Cross-platform games requiring stable 60+ FPS, minimal GC pressure, and proper object lifecycle management (pooling, caching).

witness-observer · Passive observation of worker agent health where escalation to a supervisor (mayor) is needed but the observer never modifies work or resolves conflicts.

golang-pro · Concurrent systems requiring fine-grained goroutine lifecycle, bounded resource pools, and time-bounded execution with proper cancellation.

accessibility-patterns · When using accessibility patterns in skill contexts.

graphql-architect · When using graphql architect in skill contexts.

kit · When using kit in skill contexts.

api-design · designing APIs, choosing status codes, or creating endpoints

java-architect · building, configuring, or debugging enterprise Java applications with Spring Boot 3

ci-cd-patterns · CI/CD pipeline best practices for GitHub Actions, deployment strategies, and pipeline optimization

javascript-pro · building vanilla JavaScript applications, implementing Promise-based async flows, optimising browser or Node

kubernetes-specialist · deploying or managing Kubernetes workloads

docker-patterns · Best for building production Docker images with multi-stage builds and security hardening.

laravel-specialist · Best for developing Laravel 10+ applications with Eloquent models, API resources, and queues.

env-setup · Best for securing environment configurations and preventing secrets from leaking into version control.

legacy-modernizer · Best for incrementally modernizing legacy systems without disrupting production operations.
