## pi-workflows: Extending AI Programming Assistant pi with Workflow Orchestration

pi-workflows is an extension for the TUI-based AI programming assistant pi, enabling developers to define multi-step AI agent pipelines using simple JavaScript/TypeScript scripts. It supports running, monitoring, and debugging these workflows via pi's TUI, addressing the limitation of single-round AI assistant interactions for complex tasks. Key features include phase-based structuring, traceability, structured output with JSON Schema, and a local web dashboard for visualization.

## The Need for Workflow Orchestration in AI Programming Assistants

AI programming assistants have evolved from code completion to context-aware tools, but most still operate in single-round dialogue mode. This falls short for complex tasks requiring multi-step, dependent actions (e.g., analyzing code structure → modifying files → running tests). pi-workflows was created to solve this by enabling structured orchestration of AI agent execution.

## pi-workflows: Core Design & Key Principles

pi-workflows is an extension for pi (a TUI AI assistant by earendil-works). Its core value is letting developers define complex workflows with JS/TS scripts and run them via pi's TUI. Design principles:
- **Phases**: Workflows split into logical stages (e.g., Discover, Analyze).
- **Traceability**: Every step's state, time, and output are recorded for debugging/audit.
- **Structured Output**: AI outputs can be validated with JSON Schema for reliable use in subsequent steps.
- **Concurrency**: Parallel processing within stages while maintaining order between stages.

## Runtime API & Workflow Execution

pi-workflows provides a runtime API for workflow scripts:
1. **agent(prompt, opts)**: Calls an AI agent with tools (file access, bash) and optional JSON Schema for structured output.
2. **pipeline(items, ...stages)**: Processes items in parallel within stages, sequentially between stages.
3. **step(name, phase, fn)**: Wraps non-AI local tasks for traceability.
4. **log(message)**: Shows progress notifications.

Example workflow: Define meta (name, phases) and an execution function using the API. Workflows are discovered from local/global directories (e.g., `.pi/workflows/`). Commands like `/workflow start test-plan` run workflows; `/dashboard` launches a web UI for visualization.

## Implementation & Best Practices

Technical modules: index.ts (entry), loader.ts (workflow discovery), runtime.ts (API), store.ts (persistence), types.ts (TypeScript types). Uses Bun runtime with 39 unit tests.

Constraints/best practices:
- All declared phases must be used in code.
- Non-AI tasks must use `step` instead of raw code.
- Phase names in code must match meta exactly.
- Deconstruct runtime functions (agent, pipeline, etc.) in the workflow function signature.

## Use Cases & Unique Advantages

Ideal scenarios: batch code refactoring, test generation, documentation creation, dependency analysis, code reviews.

Compared to LangChain/AutoGPT:
- **TUI Integration**: Seamless with pi's terminal workflow (no context switch).
- **Simplicity**: Uses standard JS/TS (no complex DSL).
- **Traceability**: Full step logging.
- **Structured Output**: Native JSON Schema support.

## Limitations, Future Plans & Final Thoughts

Current limitations: lack of workflow dependency/composition, limited visualization options, no template sharing, no CI/CD integration. Future directions: address these gaps.

Conclusion: pi-workflows evolves AI assistants from passive tools to active task partners, enabling structured, reproducible use of AI for complex dev tasks. For pi users, it's a valuable extension to enhance AI utility in software development. Project link: https://github.com/umutbasal/pi-workflows.
