Project Completion Knowledge Extraction

Project Completion: Knowledge Extraction Pattern

Pattern Type: Project Management Applies To: All projects that deploy to production or create reusable patterns Last Updated: 2025-10-07 Validated: feature-salesjournaltoreact (production deployment)

Core Principle

Sandbox work must be distributed to proper repositories when complete.

Projects in projects/active/ are SANDBOXES for coordination. When projects complete:

• Code goes to production repositories
• Documentation goes to multiple locations based on audience
• Knowledge gets extracted for agent learning
• Each repository gets its own PR (never mix repos in one commit)

The Problem This Solves

Before this pattern:

• All work stayed in project sandbox
• Documentation duplicated across repos
• Agents couldn't find patterns from completed projects
• READMEs became novels (500+ lines)
• Maintenance nightmare (update docs in 3 places)

After this pattern:

• Clear separation of concerns
• Zero duplication (single source of truth per topic)
• Agents discover knowledge via three-tier system
• Lightweight READMEs (< 200 lines)
• Update once, links work everywhere

Three-Tier Documentation Architecture

Tier 1: Repository README (Lightweight)

Location: <repo>/README.md (e.g., react-customer-dashboard/README.md) Purpose: Get developers productive FAST Size: < 200 lines Contains:

• App purpose (2-3 sentences)
• Quick start (npm install, npm run dev)
• Technology stack (bullet list)
• Architecture overview (1 paragraph + link to Tier 2)
• Deployment quick reference (commands + link to Tier 2)
• Troubleshooting (quick fixes + link to Tier 2)

Audience: Human developers, AI agents doing code-level work IN that repo

Template:

# App Name

One-sentence purpose.

**Production**: https://...

## Quick Start
npm install && npm run dev

## What This App Does
- Key feature 1
- Key feature 2

## Technology Stack
- Frontend: React + TypeScript
- Backend: FastAPI
- Auth: ALB OIDC

## Architecture
Brief summary (1 paragraph)

📚 For complete architecture, deployment, operations:
→ See knowledge/applications/<app-name>/ in da-agent-hub

## Deployment
Quick commands

📚 For deployment runbook:
→ See knowledge/applications/<app-name>/deployment/ in da-agent-hub

Tier 2: Knowledge Base (Comprehensive)

Location: knowledge/applications/<app-name>/ Purpose: Complete source of truth for architecture/deployment/operations Size: Unlimited Structure:

<app-name>/
├── README.md (comprehensive overview)
├── architecture/
│   ├── system-design.md (full architecture, diagrams)
│   ├── authentication-flow.md (auth details)
│   └── data-sources.md (integrations)
├── deployment/
│   ├── production-deploy.md (complete runbook)
│   ├── docker-build.md (container details)
│   └── rollback-procedures.md
└── operations/
    ├── monitoring.md (CloudWatch, health checks)
    ├── troubleshooting.md (comprehensive guide)
    └── incident-response.md

Audience: AI agents coordinating deployments, operations, cross-system work

Maintenance: Update when architecture or infrastructure changes

Tier 3: Agent Pattern Index (Pointers)

Location: .claude/agents/specialists/<agent>.md Purpose: Help agents quickly find proven patterns Size: Pattern name + confidence + link (not full content)

Format:

## Production-Validated Architecture Patterns

### ALB OIDC Authentication Pattern (Confidence: 0.92)
**Production Status**: ✅ Validated (app-portal + customer-dashboard)
**Reference**: `knowledge/applications/app-portal/architecture/alb-oidc-authentication.md`
**When to use**: React apps requiring Azure AD SSO

Audience: AI agents deciding what pattern to apply

Also Update:

• Role agents (e.g., frontend-developer-role.md) with "Known Applications" section
• Points agents to knowledge base for comprehensive docs

Separation by Repository: The Critical Rule

NEVER mix repository changes in one PR or commit.

When completing a project that touches multiple repos:

Step 1: Identify What Goes Where

da-agent-hub (Platform Knowledge):

• .claude/agents/ - Agent pattern updates
• knowledge/applications/ - Comprehensive app docs
• CLAUDE.md - Pattern documentation
• .gitignore - Config updates

Production App Repos (react-customer-dashboard, da-app-portal, etc.):

• README.md - Lightweight Tier 1 docs ONLY
• NO architecture/deployment details (link to knowledge base)

Never Put in Sandbox:

• Production code doesn't stay in projects/active/
• Project sandbox is for COORDINATION, not final destination

Step 2: Create Independent PRs

PR 1: da-agent-hub (Knowledge Base + Agent Updates)

cd da-agent-hub
git checkout main
git pull origin main
git checkout -b feat/knowledge-base-<app-name>

# Add only da-agent-hub changes
git add knowledge/applications/ .claude/agents/ CLAUDE.md .gitignore
git commit -m "feat: Add <app-name> to knowledge base with three-tier docs"
git push -u origin feat/knowledge-base-<app-name>
gh pr create

PR 2: react- (Lightweight README)

cd react-<app-name>
git checkout main  # or appropriate base branch
git pull origin main
git checkout -b docs/update-readme-with-knowledge-base-links

# Add ONLY README.md
git add README.md
git commit -m "docs: Update README with three-tier pattern"
git push -u origin docs/update-readme-with-knowledge-base-links
gh pr create --base main

PR 3: da-app-portal (if applicable)

# Same pattern as PR 2

Step 3: Archive Project Sandbox

cd da-agent-hub
git checkout main
mkdir -p projects/completed
mv projects/active/<project-name> projects/completed/
git add projects/
git commit -m "chore: Archive completed <project-name>"

Knowledge Extraction Checklist

When completing a project with production deployment:

da-agent-hub Updates

• Create knowledge/applications/<app-name>/ structure
• Write architecture/system-design.md (comprehensive)
• Write deployment/production-deploy.md (complete runbook)
• Write operations/troubleshooting.md (common issues)
• Update knowledge/applications/README.md (add app to index)
• Update specialist agent (e.g., aws-expert.md) with patterns + confidence scores
• Update role agent (e.g., frontend-developer-role.md) "Known Applications" section
• Update CLAUDE.md if pattern is novel
• Update .gitignore if new knowledge directory added

Production Repo Updates

• Create lightweight README (< 200 lines)
• Include quick start for local dev
• Link to knowledge base for comprehensive docs
• Remove duplicated architecture/deployment details
• Keep troubleshooting quick fixes (link for comprehensive)

Project Archival

• Move projects/active/<name> to projects/completed/
• Commit archival to da-agent-hub main branch
• Document where knowledge was extracted (commit message)

Anti-Patterns to Avoid

❌ Mixing repos in one PR

# WRONG - This mixes da-agent-hub and react-app changes
git add knowledge/ ../react-app/README.md
git commit -m "Update everything"

✅ Separate PRs per repo

# CORRECT - Independent PRs
# PR 1: da-agent-hub (knowledge base)
# PR 2: react-app (README only)

❌ Duplicating comprehensive docs

# WRONG - Same architecture diagram in both places
react-app/README.md: [full architecture diagram]
knowledge/applications/app/architecture/: [same diagram]

✅ Link instead of duplicate

# CORRECT - Diagram lives once, README links to it
react-app/README.md: "See knowledge/applications/... for architecture"
knowledge/applications/app/architecture/: [full diagram]

❌ Keeping work in sandbox

# WRONG - Completed work stays in projects/active/
projects/active/feature-app/production-code.ts

✅ Deploy to proper repos

# CORRECT - Code goes to production repo
react-app/src/production-code.ts
projects/completed/feature-app/ (just coordination docs)

Example: feature-salesjournaltoreact Completion

What We Had (Sandbox):

projects/active/feature-salesjournaltoreact/
├── working/ (deployment experiments)
├── tasks/ (agent coordination)
├── RESUME_POINT_*.md (session notes)
└── context.md (working state)

What We Created (Distributed):

PR #96: da-agent-hub (feat/knowledge-base-three-tier-docs)

• knowledge/applications/app-portal/ (architecture, deployment, operations)
• knowledge/applications/customer-dashboard/ (architecture, deployment, operations)
• .claude/agents/specialists/aws-expert.md (ALB OIDC 0.92, ECS 0.88)
• .claude/agents/roles/frontend-developer-role.md (Known Applications)
• CLAUDE.md (three-tier pattern docs)
• .gitignore (allow knowledge/applications/**)

PR #3: da-app-portal (docs/update-readme-with-knowledge-base-links)

• README.md (lightweight, links to knowledge base)

PR: react-customer-dashboard (docs/update-readme-with-knowledge-base-links)

• Task-aware documentation (read what you need)
• Production-validated patterns with confidence scores

For Maintenance:

• Update once in knowledge base
• Links from READMEs don't break
• No duplicated content to keep in sync
