Process Builder
Create new process definitions for the babysitter event-sourced orchestration framework.

3-Phase Workflow
Phase 1: Research & Documentation
Create foundational documentation:
# Check existing specializations
ls plugins/babysitter/skills/babysit/process/specializations/
# Check methodologies
ls plugins/babysitter/skills/babysit/process/methodologies/
Create:
README.md- Overview, roles, goals, use cases, common flowsreferences.md- External references, best practices, links to sources
Phase 2: Identify Processes
Create processes-backlog.md with identified processes:
# Processes Backlog - [Specialization Name]
## Identified Processes
- [ ] **process-name** - Short description of what this process accomplishes
- Reference: [Link to methodology or standard]
- Inputs: list key inputs
- Outputs: list key outputs
- [ ] **another-process** - Description
...
Phase 3: Create Process Files
Create .js process files following SDK patterns (see below).
Process File Structure
Every process file follows this pattern:
/**
* @process [category]/[process-name]
* @description Clear description of what the process accomplishes end-to-end
* @inputs { inputName: type, optionalInput?: type }
* @outputs { success: boolean, outputName: type, artifacts: array }
*
* @example
* const result = await orchestrate('[category]/[process-name]', {
* inputName: 'value',
* optionalInput: 'optional-value'
* });
*
* @references
* - Book: "Relevant Book Title" by Author
* - Article: [Title](https://link)
* - Standard: ISO/IEEE reference
*/
import { defineTask } from '@a5c-ai/babysitter-sdk';
/**
* [Process Name] Process
*
* Methodology: Brief description of the approach
*
* Phases:
* 1. Phase Name - What happens
* 2. Phase Name - What happens
* ...
*
* Benefits:
* - Benefit 1
* - Benefit 2
*
* @param {Object} inputs - Process inputs
* @param {string} inputs.inputName - Description of input
* @param {Object} ctx - Process context (see SDK)
* @returns {Promise<Object>} Process result

SDK Context API Reference
The ctx object provides these intrinsics:
| Method | Purpose | Behavior |
|---|---|---|
ctx.task(taskDef, args, opts?) | Execute a task | Returns result or throws typed exception |
ctx.breakpoint(payload) | Human approval gate | Pauses until approved via human |
ctx.sleepUntil(isoOrEpochMs) | Time-based gate | Pauses until specified time |
ctx.parallel.all([...thunks]) | Parallel execution | Runs independent tasks concurrently |
ctx.parallel.map(items, fn) | Parallel map | Maps items through task function |
ctx.now() | Deterministic time | Returns current Date (or provided time) |
ctx.log?.(level, msg, data?) | Logging | Optional logging helper |
ctx.runId | Run identifier | Current run's unique ID |
Task Kinds
| Kind | Use Case | Executor |
|---|---|---|
node | Scripts, builds, tests | Node.js process |
agent | LLM-powered analysis, generation | Claude Code agent |
skill | Claude Code skills | Skill invocation |
shell | System commands | Shell execution |
breakpoint | Human approval | Breakpoints UI/service |
sleep | Time gates | Orchestrator scheduling |
orchestrator_task | Internal orchestrator work | Self-routed |
Breakpoint Patterns
Basic Approval Gate
await ctx.breakpoint({
question: 'Approve to continue?',
title: 'Checkpoint',
context: { runId: ctx.runId }
});
With File References (for UI display)
await ctx.breakpoint({
question: 'Review the generated specification. Does it meet requ
