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 flows
• references.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
 */
export async function process(inputs, ctx) {
  const {
    inputName,
    optionalInput = 'default-value',
    // ... destructure with defaults
  } = inputs;

  const artifacts = [];

  // ============================================================================
  // PHASE 1: [PHASE NAME]
  // ============================================================================

  ctx.log?.('info', 'Starting Phase 1...');

  const phase1Result = await ctx.task(someTask, {

  ]);

  // ============================================================================
  // PHASE 3: [ITERATION EXAMPLE]
  // ============================================================================

  let iteration = 0;
  let targetMet = false;

  while (!targetMet && iteration < maxIterations) {
    iteration++;

    const iterResult = await ctx.task(iterativeTask, {
      iteration,
      previousResults: /* ... */
    });

    targetMet = iterResult.meetsTarget;

    if (!targetMet && iteration % 3 === 0) {
      // Periodic checkpoint
      await ctx.breakpoint({
        question: `Iteration ${iteration}: Target not met. Continue?`,
        title: 'Progress Checkpoint',
        context: { /* ... */ }
      });
    }
  }

  // ============================================================================
  // COMPLETION
  // ============================================================================

  return {
    success: targetMet,
    iterations: iteration,
    artifacts,
    // ... other outputs matching @outputs
  };
}

// ============================================================================
// TASK DEFINITIONS
// ============================================================================

/**
 * Task: [Task Name]
 * Purpose: What this task accomplishes
 */
const someTask = defineTask({
  name: 'task-name',
  description: 'What this task does',

  // Task definition - executed externally by orchestrator
  // This returns a TaskDef that describes HOW to run the task

  inputs: {
    inputName: { type: 'string', required: true },
    optionalInput: { type: 'number', default: 10 }
  },

  outputs: {
    result: { type: 'object' },
    artifacts: { type: 'array' }

  async run(inputs, taskCtx) {
    const effectId = taskCtx.effectId;

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 requirements?',
  title: 'Specification Review',
  context: {
    runId: ctx.runId,
    files: [
      { path: 'artifacts/spec.md', format: 'markdown', label: 'Specification' },
      { path: 'artifacts/spec.json', format: 'json', label: 'JSON Schema' },
      { path: 'src/implementation.ts', format: 'code', language: 'typescript', label: 'Implementation' }
    ]
  }
});

Conditional Breakpoint

if (qualityScore < targetScore) {
  await ctx.breakpoint({
    question: `Quality score ${qualityScore} is below target ${targetScore}. Continue iterating or accept current result?`,
    title: 'Quality Gate',
    context: {
      runId: ctx.runId,
      data: { qualityScore, targetScore, iteration }
    }
  });
}

---

Common Patterns

Quality Convergence Loop

let quality = 0;
let iteration = 0;
const targetQuality = inputs.targetQuality || 85;
const maxIterations = inputs.maxIterations || 10;

while (quality < targetQuality && iteration < maxIterations) {
  iteration++;
  ctx.log?.('info', `Iteration ${iteration}/${maxIterations}`);

  // Execute improvement tasks
  const improvement = await ctx.task(improveTask, { iteration });

  // Score quality (parallel checks)
  const [coverage, lint, security, tests] = await ctx.parallel.all([
    () => ctx.task(coverageTask, {}),
    () => ctx.task(lintTask, {}),
    () => ctx.task(securityTask, {}),
    () => ctx.task(runTestsTask, {})
  ]);

  // Agent scores overall quality
  const score = await ctx.task(agentScoringTask, {
    coverage, lint, security, tests, iteration
  });

  quality = score.overall;
  ctx.log?.('info', `Quality: ${quality}/${targetQuality}`);

  if (quality >= targetQuality) {
    ctx.log?.('info', 'Quality target achieved!');
    break;
  }
}

return {
  success: quality >= targetQuality,
  quality,
  iterations: iteration
};

Phased Workflow with Reviews

// Phase 1: Research
const research = await ctx.task(researchTask, { topic: inputs.topic });

await ctx.breakpoint({
  question: 'Review research findings before proceeding to planning.',
  title: 'Research Review',
  context: { runId: ctx.runId }
});

// Phase 2: Planning
const plan = await ctx.task(planningTask, { research });

await ctx.breakpoint({
  question: 'Review plan before implementation.',
  title: 'Plan Review',
  context: { runId: ctx.runId }
});

// Phase 3: Implementation
const implementation = await ctx.task(implementTask, { plan });

// Phase 4: Verification
const verification = await ctx.task(verifyTask, { implementation, plan });

await ctx.breakpoint({
  question: 'Final review before completion.',
  title: 'Final Approval',
  context: { runId: ctx.runId }
});

return { success: verification.passed, plan, implementation };

Parallel Fan-out with Aggregation

// Fan out to multiple parallel analyses
const analyses = await ctx.parallel.map(components, component =>
  ctx.task(analyzeTask, { component }, { label: `analyze:${component.name}` })
);

// Aggregate results
const aggregated = await ctx.task(aggregateTask, { analyses });

return { analyses, summary: aggregated.summary };

Process Builder Workflow

1. Gather Requirements

Ask the user:

Question	Purpose
Domain/Category	Determines directory location
Process Name	kebab-case identifier
Goal	What should the process accomplish?
Inputs	What data does the process need?
Outputs	What artifacts/results does it produce?
Phases	What are the major steps?
Quality Gates	Where should humans review?
Iteration Strategy	Fixed phases vs. convergence loop?

2. Research Similar Processes

# Find similar processes
ls plugins/babysitter/skills/babysit/process/methodologies/
ls plugins/babysitter/skills/babysit/process/specializations/

# Read similar process for patterns
cat plugins/babysitter/skills/babysit/process/methodologies/atdd-tdd/atdd-tdd.js | head -200

# Check methodology README structure
cat plugins/babysitter/skills/babysit/process/methodologies/atdd-tdd/README.md

3. Check Methodologies Backlog

cat plugins/babysitter/skills/babysit/process/methodologies/backlog.md

4. Create the Process

For Methodologies:

1. Create methodologies/[name]/README.md (comprehensive documentation)
2. Create methodologies/[name]/[name].js (process implementation)
3. Create methodologies/[name]/examples/ (sample inputs)

For Specializations:

1. If domain-specific: specializations/domains/[domain]/[spec]/
2. If engineering: specializations/[category]/[process].js
3. Create README.md, references.md, processes-backlog.md first
4. Then create individual process.js files

5. Validate Structure

Checklist:

• JSDoc header with @process, @description, @inputs, @outputs, @example, @references
• Import from @a5c-ai/babysitter-sdk
• Main export async function process(inputs, ctx)
• Input destructuring with defaults
• Clear phase comments (// === PHASE N: NAME ===)
• Logging via ctx.log?.('info', message)
• Tasks via ctx.task(taskDef, inputs)
• Breakpoints at key decision points
• Artifact collection throughout
• Return object matches @outputs schema

 */
export async function process(inputs, ctx) {
  const { feature, targetQuality = 85 } = inputs;
  // ... implementation

 */
export async function process(inputs, ctx) {
  const { prototypeName, mechanicsToTest, engine = 'Unity' } = inputs;
  // ... implementation

/**
 * @process specializations/domains/science/bioinformatics/sequence-analysis
 * @description Analyze genomic sequences using standard bioinformatics workflows
 * @inputs { sequences: array, analysisType: string, referenceGenome?: string }
 * @outputs { success: boolean, alignments: array, variants: array, report: object }
 */
export async function process(inputs, ctx) {
  const { sequences, analysisType, referenceGenome = 'GRCh38' } = inputs;
  // ... implementation
