Overview

Package workflow provides workflow state management and node implementations for AI-powered development workflows.

Core types:

  • State: Workflow execution state with git, spec, implementation, and review data
  • NodeFunc: Function signature for workflow nodes
  • NodeConfig: Configuration for node behavior (retries, transcripts, etc.)
  • Ticket: External ticket reference (Jira, GitHub issue, etc.)

Workflow nodes:

  • CreateWorktreeNode: Creates git worktree for isolated work
  • GenerateSpecNode: Generates feature specification from ticket
  • ImplementNode: Implements code based on specification
  • ReviewNode: Reviews implementation for issues
  • FixFindingsNode: Fixes issues found during review
  • RunTestsNode: Executes test suite
  • CheckLintNode: Runs linting checks
  • CreatePRNode: Creates pull request
  • NotifyNode: Sends workflow notifications

Example usage: 

state := workflow.NewState("ticket-to-pr")
state.SetTicket(workflow.Ticket{ID: "TK-421", Title: "Add feature"})
result, err := workflow.CreateWorktreeNode(ctx, state)

func NotifyNode 

func NotifyNode(ctx flowgraph.Context, state State) (State, error)
