Skill UI

Instrument LLM applications with Langfuse tracing, prompt versioning and evaluation. Covers SDK setup, masking sensitive data, span verification, dataset comparison and debugging production LLM pipelines.

This skill compares two code versions to verify semantic equivalence using semi-formal side-by-side tracing. It helps developers confirm behavior remains unchanged after refactoring, rewriting, or migration by identifying divergences in inputs, outputs, and side effects.

Locate the root cause of a confirmed failure (stack trace, failing assertion, error message, or wrong-value observation) using backward-then-forward semi-formal tracing. Provides a structured report with Primary Fault, Fault Confidence, and minimal remedy.

Find logic bugs in code files or functions through semi-formal execution tracing methodology. Analyzes Premises, Trace, Divergence, Trigger, and Remedy to identify and fix logical errors in programming code. Suitable for code review when users suspect issues without naming concrete failures.

Audit multi-role marketplace authorization across roles, resource ownership, tenant boundaries, and order-state transitions. Use this skill when access rules require evidence instead of UI assumptions, covering policy matrices, identity tracing, and field-level security checks.

This skill enables building production-ready monitoring, logging, and tracing systems for enterprise applications. It covers implementing observability strategies, managing SLIs and SLOs, and handling incident response workflows. Expertise includes distributed tracing, log management, alerting, and reliability engineering practices using tools like Prometheus, Grafana, and OpenTelemetry to ensure system stability and performance.

This skill assists in implementing comprehensive monitoring solutions including metrics collection, distributed tracing, and log aggregation. It guides you in creating insightful dashboards for system health visibility, establishing alerting strategies, and defining SLOs to reduce MTTR and enable proactive issue detection in production environments.

Builds a deterministic Software Graph from TypeScript repositories and exposes it via CLI, MCP server, and agent skills for evidence-backed architecture review, request tracing, impact analysis, and dependency topology inspection before searching source files directly.

Audit an Agent Skill, MCP server, connector, or desktop extension before installation by tracing code, dependencies, permissions, credentials, data flow, and irreversible actions.

Create realistic space phenomena such as black holes and wormholes using Three.js raymarching techniques. This skill involves numerical integration, curved-ray tracing, and GPU-based effects for procedural star fields and relativistic distortion. Essential for advanced 3D visual effects development.

Expert software engineer and systems analyst skill for deep codebase understanding, tracing actual code paths, and providing evidence-based architectural analysis. Use when users need to understand complex systems spanning many files or require pattern investigation.
