Project Bootstrapper

Philosophy: Define how code must be written before writing any code. Bugs are prevented at design time, not discovered at runtime.

This is a meta-skill — it does not write application code. It generates the rules, patterns, guardrails, and quality standards that govern all code written afterward, by any developer or AI assistant.

How It Works

[Idea] → [Interview] → [Tech Stack] → [Skill Map] → [Generate Skills] → [Validate] → [Code]

Activation

This skill activates when:

• User describes a new software project idea
• User says "bootstrap", "new project", "start from scratch", "set up project"
• User wants to generate a skill suite for an existing codebase
• User asks for coding standards, project scaffolding, or development guardrails
• Any context where skills should be created before development begins

Important: Read References First

Before generating ANY skills, you MUST read these reference files in order:

1. references/skill-catalog.md — Full catalog of 40+ skill domains
2. references/skill-template.md — Universal template every skill must follow
3. references/generation-guide.md — Domain-specific generation instructions with code
4. references/quality-standards.md — Quality checklist for generated skills
5. references/cross-cutting-concerns.md — Rules that span all skills

Phase 1: Project Intelligence Gathering

1.1 — Understand the Idea

Extract or ask about:

What (Product):

• What does this project do? (one sentence)
• What type is it? (web app, mobile app, desktop app, CLI, library/SDK, API service, browser extension, IoT, embedded, game, data pipeline, ML platform, monorepo with multiple products)
• Who is the end user? (developers, consumers, enterprise, internal team)
• What is the revenue model? (open-source, freemium, SaaS subscription, one-time purchase, marketplace, ad-supported, enterprise license)

How Big (Scale):

• Expected users at launch? At 12 months?
• Data volume? (records, files, events/sec, storage)
• Geographic scope? (single region, continental, global)
• Availability requirement? (99.9%, 99.95%, 99.99%)

How (Constraints):

• Required technologies? (must use React, must deploy on AWS, etc.)
• Existing codebase? (greenfield vs brownfield)
• Team size? (solo, small team 2-5, medium 5-15, large 15+)
• Timeline? (hackathon/weekend, MVP in weeks, production in months)
• Budget constraints? (free tier only, moderate, enterprise)
• Compliance requirements? (GDPR, HIPAA, SOC2, PCI-DSS, COPPA, CCPA)

If the user already provided details, extract answers from their message instead of asking. Only ask what's missing and genuinely needed to make tech stack decisions.

1.2 — Determine Tech Stack

Based on the answers, recommend a complete tech stack.

🔍 MANDATORY: Version Research (Latest Stable) — ZERO TOLERANCE

This is NON-NEGOTIABLE. Before proposing ANY technology, you MUST verify its latest stable version via real-time lookup.

⚠️ CRITICAL: AI models have knowledge cutoffs. Package ecosystems evolve daily. A skill generated with outdated versions will produce vulnerable, deprecated code.

Research Protocol (execute for EVERY technology):

1. Use available tools (in priority order):

   • WebSearch: "{package} latest stable version {current_year}"
   • WebFetch: Official docs site (e.g., nextjs.org, python.org, go.dev)
   • Context7: resolve-library-id → query-docs for changelog
   • Package registry: npmjs.com, pypi.org, crates.io, pkg.go.dev, maven.apache.org

2. Extract exact version:

   • Format: Major.Minor.Patch (e.g., Next.js 16.1.0)
   • Verify it's STABLE (not alpha, beta, RC, canary, nightly)
   • Note release date — reject if >6 months old without updates

3. Document verification:

   Technology: Next.js
   Version: 16.1.0
   Verified via: nextjs.org/blog
   Verification date: 2026-03-09
   Release date: 2026-02-15
   Node requirement: >= 22.0.0
   

HARDCORE RULES:

• ✅ MUST: Verify EVERY dependency, not just frameworks
• ✅ MUST: Pin exact versions in all configs (package.json, requirements.txt, Cargo.toml, etc.)
• ✅ MUST: Use latest APIs/syntax from verified version in ALL code examples
• ❌ NEVER: Use memorized versions under ANY circumstance
• ❌ NEVER: Skip verification even for "well-known" packages
• ❌ NEVER: Use deprecated APIs from older versions
• ⚠️ WARN: If verification fails, mark clearly: ⚠️ VERSION UNVERIFIED — MUST CONFIRM

Abandonment Detection:

• Last commit/release >12 months = investigate alternatives
• No maintainer response to issues >6 months = red flag
• Security advisories unpatched >30 days = DO NOT USE

Example research queries:

• "next.js latest version" → nextjs.org or npm
• "postgresql latest stable release" → postgresql.org
• "tailwind css latest version" → tailwindcss.com or npm
• Context7: resolve library ID → query docs for version/changelog

Tech Stack Decision Table

Organize as a layered decision table:

Polyglot Projects: Generate separate {language}-standards skills for each language.

1.3 — Generate Skill Map

Based on confirmed tech stack, produce a skill map — the complete list of skills to generate. Read references/skill-catalog.md for the full domain catalog.

• websocket-patterns — connection management, rooms, reconnection
• microservice-patterns — service boundaries, communication, discovery

Present the skill map organized by generation layer. Wait for user confirmation.

Phase 2: Skill Generation Engine

2.1 — Generation Order (Dependency Layers)

Generate skills in strict dependency order — later skills can reference earlier ones:

Layer 0: project-architecture
         (defines folder structure, module boundaries, naming — everything else references this)

Layer 1: {language}-standards, git-workflow, documentation-standards
         (foundational coding and process standards)

Layer 2: security-hardening, error-handling, data-validation, privacy-compliance,
         dependency-management
         (cross-cutting safety and quality concerns)

Layer 3: database-design, api-design, auth-patterns, caching-strategy
         (data and communication layer)

Layer 4: {framework}-patterns, ui-engineering, state-management,
         accessibility-standards
         (presentation and interaction layer)

Layer 5: testing-strategy, performance-optimization
         (quality assurance — needs all other skills to exist first)

Layer 6: devops-pipeline, observability, container-orchestration,
         infrastructure-as-code
         (operations layer)

Layer 7: Domain-specific skills (payments, i18n, email, search, realtime,
         background-jobs, feature-flags, AI, etc.)
         (only relevant domains)

2.2 — Skill File Structure

Every generated skill MUST produce this file tree:

{skill-name}/
├── SKILL.md              # Main instructions (< 500 lines)
├── references/
│   ├── patterns.md       # Approved patterns with full code examples
│   ├── anti-patterns.md  # Forbidden patterns with severity + explanation
│   └── checklist.md      # Pre-commit/pre-merge verification checklist
└── templates/            # (optional) Code templates, configs
    └── *.template.*

2.3 — Content Requirements

Read references/skill-template.md for the exact skeleton. Read references/generation-guide.md for domain-specific content requirements.

Every generated skill MUST contain:

1. YAML frontmatter — name + aggressive description for reliable triggering
2. Activation conditions — exact triggers (file types, directories, user phrases)
3. Project context — references to actual project tech, paths, decisions
4. Numbered core rules (15-40 per skill) — each with rationale + code examples
5. Approved patterns — copy-pasteable code showing the right way
6. Anti-patterns with severity (🔴 CRITICAL / 🟠 HIGH / 🟡 MEDIUM / 🟢 LOW)
7. Performance budgets — concrete measurable numbers, not vague goals
8. Security checklist — domain-specific security verification items
9. Error scenarios table — what fails, how to detect, how to recover
10. Edge cases — documented with handling instructions
11. Integration points — how this skill connects to other generated skills
12. Pre-commit checklist — verification items before code can be committed

2.4 — Writing Principles

• Explain the WHY: Claude and developers are smart — reasoning > rigid commands
• Concrete over abstract: Real code examples > descriptions of code
• Project-specific: Reference actual tech choices, paths, and decisions — never generic
• Opinionated: Pick one best approach and enforce it, don't offer menus
• Testable: Every rule must be verifiable (lint rule, test, code review check)
• Examples compile: All code examples must work if copy-pasted, no pseudocode
• Both sides: Show correct AND incorrect for every critical rule

2.5 — Cross-Skill Consistency

After generating all skills, verify:

• No contradictions between skills
• Shared terminology is consistent across all skills
• Import paths reference actual project structure
• Tech versions match across all skills
• Error handling patterns are uniform
• Logging format is identical everywhere
• Validation approach is the same everywhere
• Security rules don't conflict

Phase 3: Output

3.1 — Directory Layout

3.2 — Bootstrap Manifest

Generate _bootstrap-manifest.json:

{
  "project": "{name}",
  "bootstrapped_at": "{ISO-8601}",
  "tech_stack": {},
  "skills_generated": [
    {
      "name": "{skill-name}",
      "path": ".claude/skills/{skill-name}/",
      "layer": 0,

    "testing": true,
    "accessibility": true,
    "error_handling": true,
    "documentation": true,
    "observability": true
  }
}

Phase 4: Validation

Before declaring bootstrap complete, run validation using both JavaScript and Python validators:

Validation Checklist

1. Completeness — Every tech stack component is covered by at least one skill
2. Contradictions — No two skills give conflicting advice
3. Dependencies — Every skill's depends_on targets exist
4. Coverage — Security, performance, privacy, testing, error handling all covered
5. Specificity — Skills reference actual project names, paths, versions
6. Quality — Run validators against the generated skills

Running Validators

JavaScript/Node.js (default):

# Validate all skills
node scripts/validate_bootstrap.js .claude/skills/

# Check version consistency
node scripts/version_checker.js .claude/skills/

# Check compliance (if you have source code)
node scripts/check_skill_compliance.js src/

Python (alternative):

# Validate all skills
python scripts/validate_bootstrap.py .claude/skills/

# Check version consistency
python scripts/version_checker.py .claude/skills/

# Check compliance
python scripts/check_skill_compliance.py src/

Validation Output

Present a summary table:

╔═══════════════════════════════════════════════════╗
║  BOOTSTRAP COMPLETE                               ║
╠═══════════════════════════════════════════════════╣

╚═══════════════════════════════════════════════════╝

Phase 5: Continuous Compliance (project-manager skill)

CRITICAL: After bootstrap, the project-manager skill ensures ongoing compliance:

What project-manager Does

• Monitors all code changes in real-time
• Validates every modification against active skills
• Blocks commits with skill violations
• Reports compliance metrics weekly
• Guides developers back to skill compliance
• Detects skill drift automatically

Tools Available

JavaScript:

# Check code compliance
node scripts/check_skill_compliance.js src/

# Analyze skill coverage
node scripts/analyze_skill_coverage.js src/

# Generate weekly report
node scripts/generate_compliance_report.js --week

Python:

# Check code compliance
python scripts/check_skill_compliance.py src/

# Analyze skill coverage
python scripts/analyze_skill_coverage.py src/

# Generate weekly report
python scripts/generate_compliance_report.py --week

Pre-Commit Hooks

Set up automated compliance checking:

# Install pre-commit hook
cp scripts/pre-commit.example .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit

Result: Skills become active guardrails, not just documentation.

Phase 6: Handoff

After bootstrap and validation:

1. Confirm all skills are generated in .claude/skills/
2. Explain the project-manager skill will monitor compliance
3. Show how to run validators (both JS and Python options)
4. Demonstrate compliance checking commands
5. Transition to actual development

Every file created or edited will be governed by the relevant skills automatically, enforced by the project-manager skill.

Rules for This Skill

Core Principles

• This skill generates OTHER skills — it never generates application code
• Generated skills must be project-specific, not generic boilerplate
• When in doubt, generate MORE skills rather than fewer
• If the user's project needs a domain not in the catalog, invent a new skill for it
• Follow the user's language preference (English by default)
• The tech stack is tech-agnostic: works for TypeScript, Python, Go, Rust, Java, C#, Swift, Kotlin, PHP, Ruby, or any combination
• For polyglot projects, generate per-language skills
• Read ALL reference files before generating ANY skills

Validation Requirements

ALWAYS run validators after generation:

# Option 1: JavaScript/Node.js (recommended, no Python needed)
node scripts/validate_bootstrap.js .claude/skills/

# Option 2: Python (if available)
python scripts/validate_bootstrap.py .claude/skills/

Validation must pass before declaring bootstrap complete.

Required Skills

ALWAYS generate the project-manager skill alongside other skills. It:

• Monitors compliance throughout development
• Validates code against skills in real-time
• Generates compliance reports
• Prevents skill drift

Version Verification

CRITICAL: Every technology version MUST be verified via real-time lookup:

• Use WebSearch, WebFetch, or Context7
• Document verification source and date
• Never use memorized versions
• Verify ALL dependencies, not just frameworks

Post-Generation Checklist

Before handoff:

• All skills generated in .claude/skills/
• project-manager skill included
• Validation passed (JS or Python)
• Version checker run
• _bootstrap-manifest.json created
• Compliance tools explained to user
• Pre-commit hooks mentioned
