Methodology Bootstrapping

Apply Bootstrapped AI Methodology Engineering (BAIME) to systematically develop and validate software engineering methodologies through observation, codification, and automation.

The best methodologies are not designed but evolved through systematic observation, codification, and automation of successful practices.

What is BAIME?

BAIME (Bootstrapped AI Methodology Engineering) is a unified framework that integrates three complementary methodologies optimized for LLM-based development:

1. OCA Cycle (Observe-Codify-Automate) - Core iterative framework
2. Empirical Validation - Scientific method and data-driven decisions
3. Value Optimization - Dual-layer value functions for quantitative evaluation

This skill provides the complete BAIME framework for systematic methodology development. The methodology is especially powerful when combined with AI agents (like Claude Code) that can execute the OCA cycle, coordinate specialized agents, and calculate value functions automatically.

Key Innovation: BAIME treats methodology development like software development—with empirical observation, automated testing, continuous iteration, and quantitative metrics.

When to Use This Skill

Use this skill when you need to:

• 🎯 Create systematic methodologies for testing, CI/CD, error handling, observability, etc.
• 📊 Validate methodologies empirically with data-driven evidence
• 🔄 Evolve practices iteratively using OCA (Observe-Codify-Automate) cycle
• 📈 Measure methodology quality with dual-layer value functions
• 🚀 Achieve rapid convergence (typically 3-7 iterations, 6-15 hours)
• 🌍 Create transferable methodologies (70-95% reusable across projects)

Don't use this skill for:

• ❌ One-time ad-hoc tasks without reusability goals
• ❌ Trivial processes (<100 lines of code/docs)
• ❌ When established industry standards fully solve your problem

Quick Start with BAIME (10 minutes)

1. Define Your Domain

Choose what methodology you want to develop using BAIME:

• Testing strategy (15x speedup example)
• CI/CD pipeline (2.5-3.5x speedup example)
• Error recovery patterns (80% error reduction example)
• Observability system (23-46x speedup example)
• Dependency management (6x speedup example)
• Documentation system (47% token cost reduction example)
• Knowledge transfer (3-8x speedup example)
• Technical debt management
• Cross-cutting concerns

2. Establish Baseline

Measure current state:

# Example: Testing domain
- Current coverage: 65%
- Test quality: Ad-hoc
- No systematic approach
- Bug rate: Baseline

# Example: CI/CD domain
- Build time: 5 minutes
- No quality gates
- Manual releases

3. Set Dual Goals

Define both layers:

• Instance goal (domain-specific): "Reach 80% test coverage"
• Meta goal (methodology): "Create reusable testing strategy with 85%+ transferability"

4. Start Iteration 0

Follow the OCA cycle (see reference/observe-codify-automate.md)

Specialized Subagents

BAIME provides two specialized Claude Code subagents to streamline experiment execution:

iteration-prompt-designer

When to use: At experiment start, to create comprehensive ITERATION-PROMPTS.md

What it does:

• Designs iteration templates tailored to your domain
• Incorporates modular Meta-Agent architecture
• Provides domain-specific guidance for each iteration
• Creates structured prompts for baseline and subsequent iterations

How to invoke:

Use the Task tool with subagent_type="iteration-prompt-designer"

Example:
"Design ITERATION-PROMPTS.md for refactoring methodology experiment"

Benefits:

• ✅ Comprehensive iteration prompts (saves 2-3 hours setup time)
• ✅ Domain-specific value function design
• ✅ Proper baseline iteration structure
• ✅ Evidence-driven evolution guidance

iteration-executor

When to use: For each iteration execution (Iteration 0, 1, 2, ...)

What it does:

• Executes iteration through lifecycle phases (Observe → Codify → Automate → Evaluate)
• Coordinates Meta-Agent capabilities and agent invocations
• Tracks state transitions (M_{n-1} → M_n, A_{n-1} → A_n, s_{n-1} → s_n)
• Calculates dual-layer value functions (V_instance, V_meta) systematically
• Evaluates convergence criteria rigorously
• Generates complete iteration documentation

How to invoke:

Use the Task tool with subagent_type="iteration-executor"

Example:
"Execute Iteration 2 of testing methodology experiment using iteration-executor"

Benefits:

• ✅ Consistent iteration structure across experiments
• ✅ Systematic value calculation (reduces bias, improves honesty)
• ✅ Proper convergence evaluation (prevents premature convergence)
• ✅ Complete artifact generation (data, knowledge, reflections)
• ✅ Reduced iteration time (structured execution vs ad-hoc)

Important: iteration-executor reads capability files fresh each iteration (no caching) to ensure latest guidance is applied.

knowledge-extractor

When to use: After experiment converges, to extract and transform knowledge into reusable artifacts

What it does:

• Extracts patterns, principles, templates from converged BAIME experiment
• Transforms experiment artifacts into production-ready Claude Code skills
• Creates knowledge base entries (patterns/*.md, principles/*.md)
• Validates output quality with structured criteria (V_instance ≥ 0.85)
• Achieves 195x speedup (2 min vs 390 min manual extraction)
• Produces distributable, reusable artifacts for the community

How to invoke:

Use the Task tool with subagent_type="knowledge-extractor"

Example:
"Extract knowledge from Bootstrap-004 refactoring experiment and create code-refactoring skill using knowledge-extractor"

Benefits:

• ✅ Systematic knowledge preservation (vs ad-hoc documentation)
• ✅ Reusable Claude Code skills (ready for distribution)
• ✅ Quality validation (95% content equivalence to hand-crafted)
• ✅ Fast extraction (2-5 min, 195x speedup)
• ✅ Knowledge base population (patterns, principles, templates)
• ✅ Automated artifact generation (43% workflow automation with 4 tools)

Lifecycle position: Post-Convergence phase

Experiment Design → iteration-prompt-designer → ITERATION-PROMPTS.md
       ↓
Iterate → iteration-executor (x N) → iteration-0..N.md
       ↓
Converge → Create results.md
       ↓
Extract → knowledge-extractor → .claude/skills/ + knowledge/
       ↓
Distribute → Claude Code users

Validated performance (Bootstrap-005):

• Speedup: 195x (390 min → 2 min)
• Quality: V_instance = 0.87, 95% content equivalence
• Reliability: 100% success across 3 experiments
• Automation: 43% of workflow (6/14 steps)

Core Framework

The OCA Cycle

Observe → Codify → Automate
   ↑                    ↓
   └────── Evolve ──────┘

• Access pattern tracking
• Error rate monitoring

Codify: Extract patterns and document methodologies

• Pattern recognition from data
• Hypothesis formation
• Documentation as markdown
• Validation with real scenarios

Automate: Convert methodologies to automated checks

• Detection: Identify when pattern applies
• Validation: Check compliance
• Enforcement: CI/CD gates
• Suggestion: Automated fix recommendations

Evolve: Apply methodology to itself for continuous improvement

• Use tools on development process
• Discover meta-patterns
• Optimize methodology

Detailed guide: reference/observe-codify-automate.md

Dual-Layer Value Functions

Every iteration calculates two scores:

V_instance(s): Domain-specific task quality

• Example (testing): coverage × quality × stability × performance
• Example (CI/CD): speed × reliability × automation × observability
• Target: ≥0.80

V_meta(s): Methodology transferability quality

• Components: completeness × effectiveness × reusability × validation
• Completeness: Is methodology fully documented?
• Effectiveness: What speedup does it provide?
• Reusability: What % transferable across projects?
• Validation: Is it empirically validated?
• Target: ≥0.80

Detailed guide: reference/dual-value-functions.md

Convergence Criteria

Methodology complete when:

1. ✅ System stable: Agent set unchanged for 2+ iterations
2. ✅ Dual threshold: V_instance ≥ 0.80 AND V_meta ≥ 0.80
3. ✅ Objectives complete: All planned work finished
4. ✅ Diminishing returns: ΔV < 0.02 for 2+ iterations

Alternative patterns:

• Meta-Focused Convergence: V_meta ≥ 0.80, V_instance ≥ 0.55 (when methodology is primary goal)
• Practical Convergence: Combined quality exceeds metrics, justified partial criteria

Detailed guide: reference/convergence-criteria.md

Iteration Documentation Structure

Every BAIME iteration must produce a comprehensive iteration report following a standardized 10-section structure. This ensures consistent quality, complete knowledge capture, and reproducible methodology development.

File Naming Convention

iterations/iteration-N.md

Where N = 0, 1, 2, 3, ... (starting from 0 for baseline)

Documentation Quality Standards

Evidence-based scores:

• Every value component score must have concrete evidence
• Avoid vague assessments ("seems good" ❌, "72.3% coverage, +5% from baseline" ✅)
• Show arithmetic for all calculations

Honest assessment:

• Low scores early are expected and acceptable (baseline V_meta often 0.15-0.25)
• Don't inflate scores to meet targets
• Document gaps explicitly
• Acknowledge when objectives are not met

Complete coverage:

• All 10 sections must be present
• Don't skip reflections (valuable for meta-learning)
• Don't skip gap analysis (critical for planning)
• Don't skip convergence check (prevents premature convergence)

Tools for Iteration Documentation

Recommended workflow:

1. Copy examples/iteration-structure-template.md to iterations/iteration-N.md
2. Invoke iteration-executor subagent to execute iteration with structured documentation
3. Review examples/iteration-documentation-example.md for quality reference

Automated generation: Use iteration-executor subagent to ensure consistent structure and systematic value calculation.

Three-Layer Architecture

BAIME integrates three complementary methodologies into a unified framework:

Layer 1: Core Framework (OCA Cycle)

• Observe → Codify → Automate → Evolve
• Three-tuple output: (O, Aₙ, Mₙ)
• Self-referential feedback loop
• Agent coordination

Layer 2: Scientific Foundation (Empirical Methodology)

• Empirical observation tools
• Data-driven pattern extraction
• Hypothesis testing
• Scientific validation

Layer 3: Quantitative Evaluation (Value Optimization)

• Dual-layer value functions (V_instance + V_meta)
• Convergence mathematics
• Agent as gradient, Meta-Agent as Hessian
• Optimization perspective

Why "BAIME"? The framework bootstraps itself—methodologies developed using BAIME can be applied to improve BAIME itself. This self-referential property, combined with AI-agent coordination, makes it uniquely suited for LLM-based development tools.

Usage Templates

Experiment Template

Use templates/experiment-template.md to structure your methodology development:

• README.md structure
• Iteration prompts
• Knowledge extraction format
• Results documentation

Iteration Prompt Template

Use templates/iteration-prompts-template.md to guide each iteration:

• Iteration N objectives
• OCA cycle execution steps
• Value calculation rubrics
• Convergence checks

Automated generation: Use iteration-prompt-designer subagent to create domain-specific iteration prompts.

Iteration Documentation Template

Structure template: examples/iteration-structure-template.md

• 10-section standardized structure
• Blank template ready to copy and fill
• Includes all required components

Complete example: examples/iteration-documentation-example.md

• Real iteration from test strategy experiment
• Shows proper value calculations with evidence
• Demonstrates honest assessment and gap analysis
• Illustrates quality reflections and insights

Automated execution: Use iteration-executor subagent to ensure consistent structure and systematic value calculation.

Quality standards:

• Evidence-based scoring (concrete data, not vague assessments)
• Honest evaluation (low scores acceptable, inflation harmful)
• Complete coverage (all 10 sections required)
• Arithmetic shown (all value calculations with steps)

Common Pitfalls

❌ Don't:

• Use only one methodology layer in isolation (except quick prototyping)
• Predetermine agent evolution path (let specialization emerge from data)
• Force convergence at target iteration count (trust the criteria)
• Inflate value metrics to meet targets (honest assessment critical)
• Skip empirical validation (data-driven decisions only)

✅ Do:

• Start with OCA cycle, add evaluation and validation
• Let agent specialization emerge from domain needs
• Trust the convergence criteria (system knows when done)
• Calculate V(s) honestly based on actual state
• Complete all analysis thoroughly before codifying

Iteration Documentation Pitfalls

❌ Don't:

• Skip iteration documentation (every iteration needs iteration-N.md)
• Calculate V-scores without component breakdowns and evidence
• Use vague assessments ("seems good", "probably 0.7")
• Omit gap analysis or convergence checks
• Document only successes (failures provide valuable learnings)
• Assume convergence without systematic criteria evaluation
• Inflate scores to meet targets (honesty is critical)
• Skip reflections section (meta-learning opportunity)

✅ Do:

• Use iteration-executor subagent for consistent structure
• Provide concrete evidence for each value component
• Show arithmetic for all calculations
• Document both instance and meta layer gaps explicitly
• Include reflections (what worked, didn't work, learnings, insights)
• Be honest about scores (baseline V_meta of 0.20 is normal and acceptable)
• Follow the 10-section structure for every iteration
• Reference iteration documentation example for quality standards
