executing-plans
Use when you have a written implementation plan to execute in a separate session with review checkpoints. Alternative to subagent-driven development for batch execution.
overview-exploration
This skill should be used when performing quick project overview exploration at the start of ultrawork sessions. Executes directly without agent spawn for fast codebase understanding.
jcl-migration-analyzer
Analyzes legacy JCL (Job Control Language) scripts to assist with migration to modern workflow orchestration and batch processing systems. Extracts job flows, step sequences, data dependencies, conditional logic, and program invocations. Generates migration reports and creates implementation strategies for Spring Batch, Apache Airflow, or shell scripts. Use when working with mainframe job migration, JCL analysis, batch workflow modernization, or when users mention JCL conversion, analyzing .jcl/.JCL files, working with job steps, procedures, or planning workflow orchestration from JCL jobs.
bash-script-generator
Generate Bash 3.2-compatible scripts with a standardized check_requirements guardrail, friendly validation errors, and optional shfmt formatting. Use when writing or updating bash scripts that need consistent argument validation, dependency checks, and portability.
bash-linux
Bash/Linux terminal patterns. Critical commands, piping, error handling, scripting. Use when working on macOS or Linux systems.
zen-runner
Zen is the Executor. Autonomous task runner powered by zen-mode CLI. Runs development tasks from start to finish without human intervention. Invoke with "Zen, run this task" or delegate well-defined work.
database-workflows
Database workflows - schema design, migrations, query optimization. Use when designing schemas, reviewing migrations, optimizing queries, preventing N+1 problems, or working with ORMs like Prisma, Drizzle, and TypeORM.
data-engineering
Automatically reviews data pipelines, optimizes SQL queries, and ensures data quality. Activates when you mention: data pipeline, ETL, SQL optimization, query performance, data quality, schema design, Airflow DAG, database index, slow query. Provides: Pipeline design patterns, SQL query optimization, index recommendations, data validation strategies, schema improvements. Supports: PostgreSQL, MySQL, SQLAlchemy, Prisma, Spring Data JPA
code-execution-helper
Guide for using code execution capabilities to perform parallel batch processing, conditional filtering, and data aggregation. This skill should be used when agents need to analyze multiple files efficiently, validate large result sets, aggregate data from multiple sources, or reduce token consumption through execution-based filtering. Provides reusable templates for quota-aware workflows, error handling patterns, and token-efficient data processing.
cli-agent-runner
Use this skill when you need to invoke another Claude Code session via the cli-agent-runner.sh script to perform specialized, potentially long-running tasks in a simplified way. This wrapper handles session management, result extraction, and can be run in background with polling support.
python-venv
Bootstrap Python projects with virtual environments and modern tooling. Use when creating Python applications, scripts, APIs, data science projects, or when the user wants a properly configured Python development environment.
uv-package-manager
Manage Python projects and dependencies using UV, the ultra-fast Rust-based package manager. Use when creating Python projects, managing dependencies, or running Python scripts.
claude-helper
A generic helper for various tasks. Assists with common operations.
managing-local-system
Manages local filesystem operations, runs shell commands, and performs calculations. Use when working with local files, directories, executing shell commands, or doing mathematical calculations.
state-directory-manager
Manage persistent state directories for bash scripts
east-node-std
Node.js platform functions for the East language. Use when writing East programs that need Console I/O, FileSystem operations, HTTP Fetch requests, Cryptography, Time operations, Path manipulation, Random number generation, or Testing. Triggers for: (1) Writing East programs with @elaraai/east-node-std, (2) Using platform functions like Console.log, FileSystem.readFile, Fetch.get, Crypto.uuid, Time.now, Path.join, Random.normal, (3) Testing East code with describeEast and Assert.
