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, {
    // task inputs
  });

  artifacts.push(...(phase1Result.artifacts || []));

  // Breakpoint for human review (when needed)
  await ctx.breakpoint({
    question: 'Review the results and approve to continue?',
    title: 'Phase 1 Review',
    context: {
      runId: ctx.runId,
      files: [
        { path: 'artifacts/output.md', format: 'markdown', label: 'Output' }
      ]
    }
  });

  // ============================================================================
  // PHASE 2: [PHASE NAME] - Parallel Execution Example
  // ============================================================================

  const [result1, result2, result3] = await ctx.parallel.all([
    () => ctx.task(task1, { /* args */ }),
    () => ctx.task(task2, { /* args */ }),
    () => ctx.task(task3, { /* args */ })
  ]);

  // ============================================================================
  // 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;

    return {
      kind: 'node',  // or 'agent', 'skill', 'shell', 'breakpoint'
      title: `Task: ${inputs.inputName}`,
      node: {
        entry: 'scripts/task-runner.js',
        args: ['--input', inputs.inputName, '--effect-id', effectId]
      },
      io: {
        inputJsonPath: `tasks/${effectId}/input.json`,
        outputJsonPath: `tasks/${effectId}/result.json`
      },
      labels: ['category', 'subcategory']
    };
  }
});

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:

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

Examples by Type

Methodology Process (atdd-tdd style)

/**
 * @process methodologies/my-methodology
 * @description My development methodology with quality convergence
 * @inputs { feature: string, targetQuality?: number }
 * @outputs { success: boolean, quality: number, artifacts: array }
 */
export async function process(inputs, ctx) {
  const { feature, targetQuality = 85 } = inputs;
  // ... implementation
}

Specialization Process (game-development style)

/**
 * @process specializations/game-development/core-mechanics-prototyping
 * @description Prototype and validate core gameplay mechanics through iteration
 * @inputs { prototypeName: string, mechanicsToTest: array, engine?: string }
 * @outputs { success: boolean, mechanicsValidated: array, playtestResults: object }
 */
export async function process(inputs, ctx) {
  const { prototypeName, mechanicsToTest, engine = 'Unity' } = inputs;
  // ... implementation
}

Domain Process (science/research style)

/**
 * @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
}
