# voltagent-data-ai A pack of subagents for Claude covering data pipelines, model training, LLM work and database tuning. Useful when a project hits ETL or ML work. - plugin · `type=plugin` · Claude Code · ★ 26065 - Author: VoltAgent Community - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/VoltAgent/awesome-claude-code-subagents/tree/HEAD/categories/05-data-ai - Updated: 2026-10-11 - HTML: https://affpapa.org/en/nevibecode/plugins/voltagent-data-ai ## What it does The plugin adds thirteen data and machine learning subagents to Claude. Among them `data-engineer` for ETL/ELT and warehouses, `ml-engineer` and `machine-learning-engineer` for training and shipping models, `llm-architect` for prompts and fine-tuning, `nlp-engineer` for text processing, `postgres-pro` for PostgreSQL queries and schemas. Narrower roles are there too: `reinforcement-learning-engineer` with algorithms such as PPO, SAC and DQN, `mlops-engineer` for model monitoring and versioning, plus `prompt-engineer`, `data-analyst`, `data-scientist`, `database-optimizer` and `ai-engineer`. You pick by task, not by stack. Building a pipeline calls for `data-engineer`, a slow query goes to `database-optimizer`, a model that needs monitoring goes to `mlops-engineer`. The README ships a quick selection table if reading thirteen descriptions sounds tedious. Worth installing if you already work in Claude and want a separate agent for each stage of the ML lifecycle. It does not replace the libraries or the infrastructure: a subagent will help you shape a pipeline, but Spark, Airflow or the cluster are still yours to run. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin marketplace add VoltAgent/awesome-claude-code-subagents ``` In the agent chat (not a shell): ```text /plugin install voltagent-data-ai@voltagent-subagents ``` ## When to use it - build an ETL pipeline from scattered sources - speed up slow PostgreSQL queries and rebuild indexes - take a model from notebook to production with monitoring - design prompts and fine-tuning for a specific task - parse text data and pull entities out of it ## Example prompts - help me design an ETL pipeline: data comes from an API and lands in a warehouse - this PostgreSQL query runs too long, look at the plan and suggest indexes - I need to deploy a model with versioning and drift monitoring ## Source text · 05-data-ai · MIT Below is the content of a third-party file.
