Skill UI

Provides a decision framework and patterns for designing applications across AWS, Azure, and GCP. Covers service comparison, migration strategies, cost optimization, and cloud-agnostic patterns like Kubernetes and Terraform. Helps architects select appropriate services and implement resilient infrastructure.

Diagnose and fix excessive Postgres egress (network data transfer) in a codebase. Use when users report high database bills, unexpected data transfer costs, egress spikes, or queries fetching more data than needed. Provides SQL diagnostics via pg_stat_statements and code-level fixes for common anti-patterns like SELECT *, missing pagination, and high-frequency static queries.

Nika is an open-source Rust engine that captures repeatable AI tasks as checkable YAML workflow files. It audits workflows before token spending, enforces strict cost budgets, and executes against local or cloud providers. Ideal for daily digests, ETL, and multi-step pipelines requiring audit trails and deterministic execution without autonomous coding capabilities.

This skill covers configuring and managing object storage solutions like AWS S3, MinIO, and GCS. It includes CLI operations for bucket management, uploading/downloading files, setting up versioning, implementing bucket policies for access control, and configuring lifecycle rules for cost optimization. Suitable for DevOps engineers managing application assets, backups, logs, and media files in cloud or on-premises environments.

A specialized AI agent designed to build and audit business models using Alexander Osterwalder’s comprehensive 9-block framework. It moves beyond mere filling of blocks, focusing on establishing the critical logical 'lock' between core components like Value Propositions, Customer Segments, and Cost Structures. This tool is ideal for initial business architecture design, auditing existing models for internal consistency (e.g., ensuring every key activity has a corresponding cost), or re-validating the core logic during a strategic pivot.

Caching strategies for LLM prompts, including Anthropic prompt caching, response caching, cache invalidation, and Cache Augmented Generation (CAG) to reduce latency and cost.

RouterBase acts as a unified, OpenAI-compatible API gateway, allowing applications to route requests across diverse large language models (LLMs) like GPT, Claude, and Gemini. It helps developers migrate existing OpenAI SDK calls, implement sophisticated primary/fallback model selection based on cost, latency, and quality, and manage multimodal payloads (image, audio, video) from a single, standardized endpoint.

A critical discipline for managing expenses when integrating paid AI or inference APIs. This guard treats dollar cost as a third complexity dimension, mandating the definition of cost contracts (max calls per run, max budget per run, max budget per day). It enforces best practices for bounding loops, retries, and fan-out, ensuring that code bugs cannot lead to unexpected overspending. Best practice requires configuring hard caps both in the code and at the provider dashboard for defense in depth.

Skill Sentinel audits and evolves a skills ecosystem by analyzing quality, security, cost, governance, documentation, dependencies, and cross-skill duplication, then generates health reports, recommendations, and orchestrates assessments for teams managing multiple automations.

A static analysis tool that audits SQL code for common cost and performance anti-patterns (e.g., full-table scans, Cartesian joins). It calculates a query health score (0-100) for data warehouses like BigQuery, Snowflake, and Redshift, providing a prioritized, actionable plan with concrete fixes and estimated cost savings. Essential for FinOps and data quality assurance.

This skill creates comprehensive 3-5 year financial models for startups, including revenue projections, cost structures, and cash flow analysis. It covers headcount planning, unit economics like CAC and LTV, and three-scenario modeling (conservative, base, optimistic) to support fundraising and strategic planning.

Create comprehensive 3-5 year financial models for early-stage startups, including revenue projections, cost structures, cash flow analysis, and scenario planning. Supports fundraising, operational strategy, and investor presentations with cohort-based revenue modeling and headcount planning.
