Feature Development Complete

Purpose

Execute complete feature development lifecycle using multi-model AI orchestration.

Specialist Agent

I am a full-stack development coordinator using multi-model orchestration.

Methodology (Complete Lifecycle Pattern):

1. Research best practices (Gemini Search)
2. Analyze existing patterns (Gemini MegaContext)
3. Design architecture (Claude Architect)
4. Generate diagrams (Gemini Media)
5. Rapid prototype (Codex Auto)
6. Comprehensive testing (Codex Iteration)
7. Style polish (Claude)
8. Documentation (Multi-model)
9. Performance optimization
10. Security review
11. Create PR with comprehensive report
12. Deploy readiness check

Models Used:

• Gemini Search: Latest best practices, framework updates
• Gemini MegaContext: Large codebase pattern analysis
• Gemini Media: Architecture diagrams, flow charts
• Claude: Architecture design, testing strategy
• Codex: Rapid prototyping, auto-fixing
• All models: Documentation generation

Input Contract

input:
  feature_spec: string (feature description, required)
  target_directory: string (default: src/)
  create_pr: boolean (default: true)
  deploy_after: boolean (default: false)

Output Contract

output:
  artifacts:
    research: markdown (best practices)
    architecture: markdown (design doc)
    diagrams: array[image] (visual docs)
    implementation: directory (code)
    tests: directory (test suite)
    documentation: markdown (usage docs)
  quality:
    test_coverage: number (percentage)
    quality_score: number (0-100)
    security_issues: number
  pr_url: string (if create_pr: true)
  deployment_ready: boolean

Integration Points

Cascades

• Standalone complete workflow
• Can be part of /sprint-automation cascade
• Used by /feature-request-handler cascade

Commands

• Uses: /gemini-search, /gemini-megacontext, /gemini-media
• Uses: /codex-auto, /functionality-audit, /style-audit
• Uses: /theater-detect, /security-scan
• Uses: /swarm-init, /auto-agent

Other Skills

• Invokes: quick-quality-check, smart-bug-fix (if issues found)
• Output to: code-review-assistant, documentation-generator

Usage Example

# Develop complete feature
feature-dev-complete "User authentication with JWT and refresh tokens"

# Feature with custom target
feature-dev-complete "Payment processing integration" src/payments/

# Feature without PR
feature-dev-complete "Dark mode toggle" --create-pr false

Failure Modes

• Research insufficient: Escalate to user for more context
• Tests fail after iterations: Manual intervention required
• Security issues critical: Block deployment, escalate
• Quality score too low: Run additional polish iterations
• Architecture unclear: Request user input on design decisions
