Use when you need a detailed breakdown of a specific cloud service's costs — EC2, RDS, S3, Lambda, etc. — to understand usage patterns and find optimization opportunities

Used to run an audit via our auditing service.

Optimize machine learning model hyperparameters using grid search, random search, or Bayesian optimization. Finds best parameter configurations to maximize performance. Use when asked to "tune hyperparameters" or "optimize model". Trigger with relevant phrases based on skill purpose.

Implement machine learning experiment tracking using MLflow or Weights & Biases. Configures environment and provides code for logging parameters, metrics, and artifacts. Use when asked to "setup experiment tracking" or "initialize MLflow". Trigger with relevant phrases based on skill purpose.

Planning pipeline with multi-mode routing (plan/verify/replan). Session discovery → context gathering (spawn_agent) → conditional conflict resolution → task generation (spawn_agent or N+1 parallel agents) → plan verification → interactive replan. Produces IMPL_PLAN.md, task JSONs, TODO_LIST.md.

Dual-mode brainstorming pipeline. Auto mode: framework generation → parallel role analysis (spawn_agents_on_csv) → cross-role synthesis. Single role mode: individual role analysis. CSV-driven parallel coordination with NDJSON discovery board.

Initialize project-level state and configure specs via interactive questionnaire.

Iterative Five Whys root cause analysis drilling from symptoms to fundamentals

Design multi-agent architectures for complex tasks. Use when single-agent context limits are exceeded, when tasks decompose naturally into subtasks, or when specializing agents improves quality.

Use for Docker with Bun, Dockerfiles, oven/bun image, containerization, and deployments.

Guide for porting a C module to Rust. Use this when starting to port a C module to Rust.

Teaches agents OS platform awareness (Windows vs Linux shell/path conventions) and social restraint around git operations. Avoids wrong-command retries and premature commit/push prompts.
