Update Repository README Skill (Enhanced)

Purpose

Autonomously audit the entire repository and update the main README with comprehensive, accurate documentation of the current codebase. This skill is designed for AI-first consumption, ensuring complete context for understanding the system holistically.

Enhanced with: Git diff intelligence, structured reporting, cross-domain impact analysis, validation, and user review workflow.

Activation

Invoke with: update-readme (no parameters required)

Example:

code

"Hey, we just finished our day. Go ahead and use your update repo README skill and go ahead and do what you need to do."

Key Enhancements

This enhanced version includes:

•Git Diff Intelligence - Parses recent commits to identify priorities and new features
•Structured JSON Reports - Sub-agents use JSON instead of markdown for easier synthesis
•Handbook Scanning - Maps available handbook files for accurate referencing
•Efficient Handbook Loading - Main agent loads once, distributes to sub-agents
•Proposed Content Drafting - Sub-agents write actual content, not just identify gaps
•Cross-Domain Impact Analysis - Identifies how changes in one domain affect others
•Conflict Resolution - Detects and resolves contradictions between agents
•Progress Tracking - TodoWrite updates keep user informed throughout execution
•Explicit Roadmap Logic - Systematic rules for updating roadmap items
•Validation Phase - Checks markdown syntax, links, duplicates before finalizing
•User Review Workflow - Shows diff summary and gets approval before committing
•No Auto-Push - User chooses whether to commit and/or push changes

Workflow Overview

Phase 1: Discovery & Preparation

Use TodoWrite immediately to track progress throughout this skill execution.

1.1 Git Diff Analysis (Enhanced)

Parse recent git activity to identify priorities:

bash

# Get commits since README was last modified
git log README.md -1 --format="%H"  # Last README commit
git log --since="24 hours ago" --name-only --pretty=format:"%s"

Extract intelligence:

•List of changed files and their paths
•Commit messages (identify new features, bug fixes, refactors)
•Folders with most activity (priority for auditing)
•New files added (might need documentation)
•Deleted files (remove from README if referenced)

Create priority map:

json

{
  "high_priority": ["amplify/auth", "src/app"],
  "new_features": ["Custom auth triggers", "Real-time subscriptions"],
  "deleted_features": [],
  "commits_analyzed": 50
}

1.2 Repository Structure Discovery

Automatically detect all major subsystems:

•/amplify - Backend infrastructure (auth, data, functions)
•/src - Frontend code (pages, components, hooks)
•amplify_outputs.json - Runtime AWS resource configuration
•TypeScript interfaces and type definitions
•GraphQL schema (AppSync)
•Package.json and environment setup
•Lambda function patterns and integrations
•Known TODOs and limitations (grep for TODO comments)

1.3 Resources Handbook Scan (NEW)

Map available handbook documentation:

bash

ls -R resources/handbook/

Create handbook map:

json

{
  "auth": ["AUTH_SETUP.md", "OAUTH_SETUP.md"],
  "data": ["GROUP_AUTHORIZATION.md", "DATA_MODELING.md"],
  "functions": ["AUTHORIZATION_EXPLAINED.md", "LAMBDA_PATTERNS.md"],
  "available": true
}

Provide this map to sub-agents so they can accurately reference handbook files.

Phase 2: Parallel Sub-Agent Audits (Enhanced)

2.1 Preparation

•Update TodoWrite: Mark "Discovery complete", set "Sub-agent audits" to in_progress
•Load handbook ONCE (main agent loads it, extracts key concepts)
•
Prepare sub-agent context package containing:
- •Current README
- •Priority map (from git diff analysis)
- •Handbook map (from resources scan)
- •Key Amplify concepts (extracted from handbook)
- •Handbook sections relevant to their domain

2.2 Spin Up 8 Sub-Agents

Each agent receives their context package (no need to load handbook independently).

CRITICAL: Ignored Folders Sub-agents must NOT read these folders (excluded from tsconfig.json):

•node_modules - Dependencies, not part of codebase
•resources - Developer handbook, not part of app
•src_original - Old/archived code
•src/warehouse - Excluded from build
•OldSource - Legacy code
•amplify/**/* (for agents auditing /src)
•context/**/* - Meeting notes, not app code
•scripts/**/* - Utility scripts, not core app

Rule: Stick to your assigned folder. Do not explore excluded directories.

2.3 Sub-Agent Execution Sequence

Each sub-agent follows this sequence:

a. Step 1: Understand the App

•Read the root README to understand what BeonIQ is
•Get context on the overall value proposition and architecture

b. Step 2: Process Pre-Loaded Amplify Knowledge

•Review Amplify Gen 2 concepts (provided in context package)
•
Focus on concepts relevant to their domain:
- •Auth agents: Cognito, SSO, group-based authorization
- •Data agents: DynamoDB, GraphQL schema, authorization rules
- •Function agents: Lambda patterns, two-pass system, resource access
- •Frontend agents: Client-side integration, hooks, providers

c. Step 3: Review Priority Map

•Check which files in their domain changed recently
•Prioritize audit efforts on high-activity areas
•Note new features from commit messages

d. Step 4: Audit Their Assigned Domain

•Read their assigned folder/subsystem thoroughly
•Compare current implementation against README section
•
Identify gaps:
- •What's documented in README but not in code?
- •What's in code but not documented in README?
- •What changed since last README update (use priority map)?
- •What doesn't follow Amplify best practices?
- •What TODOs or known limitations exist?

e. Step 5: Draft Proposed Content (NEW)

•Don't just identify gaps - write the actual content
•Draft new sections, code examples, explanations
•Include file references with line numbers

f. Step 6: Write Structured JSON Report (CHANGED)

•Create a JSON report (.readme-report-[domain].json)
•Use this structured format:

json

{
  "domain": "Backend Infrastructure",
  "agent_id": 1,
  "audit_complete": true,
  "priority_areas_reviewed": ["amplify/auth", "amplify/data"],

  "accurate_documentation": [
    {
      "topic": "Multi-tenant architecture",
      "readme_section": "Multi-Tenant Architecture",
      "status": "accurate"
    }
  ],

  "missing_documentation": [
    {
      "topic": "OAuth redirect URI configuration",
      "severity": "high",
      "readme_section": "Authentication Setup",
      "proposed_content": "After running `npx ampx sandbox`, add your unique Cognito domain to Google Cloud Console:\n1. Go to...",
      "code_references": ["amplify/auth/resource.ts:45-67"]
    }
  ],

  "outdated_documentation": [
    {
      "topic": "SUPER_ADMIN role explanation",
      "readme_section": "Multi-Tenant Architecture (line 206)",
      "current_text": "SUPER_ADMIN users...",
      "proposed_text": "SUPER_ADMIN is a platform permission...",
      "reason": "Implementation changed to require company group assignment"
    }
  ],

  "new_features_found": [
    {
      "feature": "Custom Cognito auth triggers",
      "discovered_in": "amplify/auth/resource.ts",
      "should_document": true,
      "proposed_section": "Authentication Setup > Custom Triggers",
      "proposed_content": "BeonIQ now supports custom Cognito triggers for..."
    }
  ],

  "handbook_references": [
    {
      "topic": "Lambda authorization two-pass system",
      "handbook_file": "resources/handbook/functions/AUTHORIZATION_EXPLAINED.md",
      "should_link": true,
      "suggested_location": "Development Guidelines > Lambda Authorization Pattern"
    }
  ],

  "cross_domain_impacts": [
    {
      "affects_domain": "Data Layer",
      "topic": "Group-based authorization changes",
      "note": "Auth agents modified group filtering - Data agents should verify authorization rules are documented"
    }
  ],

  "todos_found": [
    "amplify/auth/resource.ts:89: TODO: Add MFA support"
  ],

  "recommendations": [
    "Add explicit OAuth redirect URI setup steps",
    "Document custom auth trigger patterns",
    "Link to AUTHORIZATION_EXPLAINED.md from Lambda section"
  ]
}

2.4 Progress Tracking

Update TodoWrite after each agent completes:

•"Sub-agent audits (1/8 complete)"
•"Sub-agent audits (2/8 complete)"
•... etc.

This gives user visibility into progress.

Sub-Agent Assignments

Distribute domains across 8 agents:

- •GraphQL schema and operations
- •Data model contracts

Phase 2.5: Cross-Domain Impact Analysis (NEW)

Update TodoWrite: Mark "Sub-agent audits" complete, set "Cross-domain analysis" to in_progress

After all 8 JSON reports are collected, run a cross-reference check:

•
Parse all cross_domain_impacts from JSON reports
•
Identify cross-cutting concerns:
- •Auth changes that affect Data layer
- •Data model changes that affect Frontend
- •Lambda pattern changes that affect multiple domains
•
Verification pass:
- •If Agent A says "This affects Data layer", check if Data agent addressed it
- •If not, flag for synthesis agent to resolve
•
Create impact map:

json

{
  "auth_to_data": ["Group filtering changes require authorization rule updates"],
  "functions_to_frontend": ["New Lambda patterns need client-side examples"],
  "unresolved_impacts": []
}

Phase 3: Report Collection & Synthesis (Enhanced)

Update TodoWrite: Mark "Cross-domain analysis" complete, set "Synthesizing reports" to in_progress

•
Load all 8 JSON reports (structured data, easy to parse)
•
Main synthesis agent reads:
- •All 8 JSON reports
- •Cross-domain impact map (from Phase 2.5)
- •Git diffs (priority signals)
- •Current README (what exists now)
- •Handbook context (Amplify best practices)
•
Conflict Resolution (NEW):
- •
  Check for contradictions:
  - •Agent A: "X is documented accurately"
  - •Agent B: "X is missing"
- •
  If conflicts found:
  - •Re-read the actual code/README to verify ground truth
  - •Resolve based on evidence
  - •Document resolution in synthesis notes
•
Consolidate findings:
- •Merge all missing_documentation items
- •Merge all outdated_documentation items
- •Merge all new_features_found items
- •Prioritize by severity (high > medium > low)
- •Cross-reference with impact map
- •Ensure holistic consistency
•
Map to README sections:
- •Group updates by README section
- •Identify sections needing major rewrites vs. minor edits
- •Prepare structured update plan

Phase 4: README Update (Enhanced)

Update TodoWrite: Mark "Synthesizing reports" complete, set "Updating README" to in_progress

•
Apply all consolidated updates to the main README
•
Sections to check/update:
- •Key Features - Add new features found in code
- •Tech Stack - Update dependencies from package.json
- •Architecture Overview - Reflect major structural changes
- •Data Models - Add new models, update schema changes
- •Project Structure - Update folder tree if reorganized
- •Quick Start - Update setup steps if process changed
- •Development Guidelines - Add new patterns, update rules
- •Production Deployment - Update configuration requirements
- •Key Integrations - Document new external services
- •Roadmap - Apply explicit roadmap logic (see below)
•
Roadmap Update Logic (NEW):

Rules:
- •Check each roadmap item against actual code
- •Move completed items from "Post-MVP" to "MVP" section
- •Update checkboxes based on implementation status
- •Add new items if major features exist but aren't on roadmap
Example:
markdown
```
**Post-MVP Enhancements:**
- [ ] Pin/unpin functionality for dashboard customization
```
If code shows pinning is implemented:
- •Move to MVP section:
markdown
```
**MVP (November 2025):**
- ✅ Pin/unpin functionality for dashboard customization
```
If new feature found (e.g., "export to CSV"):
- •Add to Post-MVP:
markdown
```
**Post-MVP Enhancements:**
- [ ] Export insights to CSV format
```
•
Use proposed content from JSON reports:
- •Sub-agents already drafted new sections
- •Insert their proposed_content directly
- •Add code examples they provided
- •Include file references with line numbers
•
Add handbook links:
- •Use handbook references from JSON reports
- •Format: See [AUTHORIZATION_EXPLAINED.md](./resources/handbook/functions/AUTHORIZATION_EXPLAINED.md) for details

Phase 4.5: Validation (NEW)

Update TodoWrite: Mark "Updating README" complete, set "Validating changes" to in_progress

Before finalizing, validate the updated README:

•
Markdown Syntax Check:
- •Verify all code blocks are properly closed
- •Check header hierarchy (no skipped levels: H1 → H3)
- •Ensure lists are properly formatted
- •Verify tables have correct syntax
•
Link Validation:
- •
  Check all internal links point to existing files:
  - •./resources/handbook/...
  - •./amplify/...
  - •./src/...
- •Verify handbook references exist
- •Test anchor links (if any)
•
Duplicate Section Check:
- •Scan for duplicate headers
- •Check for redundant content
- •Ensure no conflicting information
•
Code Block Validation:
- •Verify code examples have language specifiers
- •Check for syntax errors in code blocks
- •Ensure examples reference actual files/line numbers
•
Completeness Check:
- •All JSON report items addressed
- •No orphaned sections
- •Roadmap properly updated

If validation fails:

•Fix issues automatically where possible
•Flag critical issues for user review

Phase 5: Review & User Approval (CHANGED)

Update TodoWrite: Mark "Validating changes" complete, set "Preparing review" to in_progress

NO AUTO-PUSH. User must review first.

•

Context Requirements for Sub-Agents

Each sub-agent receives these inputs (pre-loaded in skill prompt):

•Handbook Skill Context - Amplify Gen 2 patterns and best practices
•Current README - What's documented now
•Git Diff - What changed (for priority)
•amplify_outputs.json - What AWS resources exist
•Type Definitions - TypeScript interfaces and data models
•GraphQL Schema - AppSync API contract
•Environment Variables - Configuration requirements
•Build/Deploy Procedures - How the system runs
•TODOs & Limitations - Known incomplete areas

Critical Rules

•Holistic Audit - Examine entire repo structure, not just changed files
•AI-First Documentation - README is for AI consumption; assume agents reading it need complete context
•Amplify Fluency - All sub-agents must understand Amplify Gen 2 patterns before auditing
•Structured Reports - Domain reports use consistent format for easy synthesis
•No Artifacts - Delete all temporary reports after consolidation
•Handbook First - Sub-agents read handbook before their domain (pre-loaded)
•Root README First - Sub-agents understand the app before diving into their domain
•Context Priority - Complete context > minor optimization; better to include everything than miss connections
