Master Index Updater Skill

Master Index Updater Skill

Purpose: Automate updates to Functional Area Master Index when features or documentation change.

When to Use: After creating new functional area documentation or completing feature work.

Why the Master Index Matters

Problem: Documentation scattered across /​docs/​functional-areas/ becomes undiscoverable.

Solution: Single navigation index at /​docs/​architecture/​functional-area-master-index.md

Result: All documentation discoverable, organized by domain, with status tracking.

Master Index Structure

Location: /​docs/​architecture/​functional-area-master-index.md

Organization:

# Functional Area Master Index

## Core System
- Authentication & Authorization
- User Management
- Profile Management

## Events Domain
- Event Management
- Session Management
- Registration System

## Content & Community
- Teacher Bios
- Event Catalog
- Venue Management

## Operations
- Safety & Reporting
- Payment Processing
- Communication System

[For each area:]
## Feature Name

**Domain**: Core System | Events | Content | Operations
**Status**: Active | Deprecated | Planned
**Owner**: Team/​Agent
**Last Updated**: YYYY-MM-DD

Update Types

1. New Feature Addition

When new feature is completed:

• Add entry to appropriate domain section
• Link all documentation
• List key files
• Set status: Active
• Update last modified date

2. Feature Status Update

• Update status (Active → Deprecated)
• Add migration notes if deprecated
• Update last modified date

3. Documentation Addition

When new docs created:

• Add links to existing feature entry

• Update last modified date

4. Domain Reorganization

When functional areas restructure:

• Move entries to new domains
• Update navigation structure
• Preserve all links

How to Use This Skill

From Command Line

# Add new feature to index
bash .claude/​skills/​master-index-updater/​execute.sh \
  add \
  "Streamlined Check-in Workflow" \
  "Events Domain" \
  "docs/​functional-areas/​events/​new-work/​2025-11-03-streamlined-checkin-workflow"

# Update existing feature timestamp
bash .claude/​skills/​master-index-updater/​execute.sh \
  update \
  "Event Management" \
  "" \
  ""

# Mark feature as deprecated
bash .claude/​skills/​master-index-updater/​execute.sh \
  deprecate \
  "Legacy Registration System" \
  "" \
  ""

# Show help and usage information
bash .claude/​skills/​master-index-updater/​execute.sh --help

From Claude Code

Use the master-index-updater skill to add [feature-name] to the index

Common Usage Patterns

After organizing feature documentation (librarian):

bash .claude/​skills/​master-index-updater/​execute.sh \
  add \
  "New Feature Name" \
  "Core System" \
  "docs/​functional-areas/​auth/​new-feature"

When deprecating old feature:

bash .claude/​skills/​master-index-updater/​execute.sh \
  deprecate \
  "Old Feature Name" \
  "" \
  ""

---

Usage Examples (Legacy - For Reference)

From Librarian Agent (Automated)

After organizing feature documentation, I'll use the master-index-updater skill to add the feature to the index.

Manual Addition

# Add new feature
bash .claude/​skills/​master-index-updater.md \
  add \
  "Streamlined Check-in Workflow" \
  "Events Domain" \
  "docs/​functional-areas/​events/​new-work/​2025-11-03-streamlined-checkin-workflow"

Update Existing Feature

# Update feature timestamp
bash .claude/​skills/​master-index-updater.md \
  update \
  "Event Management" \
  "" \
  ""

Deprecate Feature

# Mark feature as deprecated
bash .claude/​skills/​master-index-updater.md \
  deprecate \
  "Legacy Registration System" \
  "" \
  ""

Integration with Librarian Agent

Librarian is responsible for:

• Creating new functional area folders
• Organizing documentation
• Updating Master Index (uses this skill)
• Maintaining navigation structure

Workflow:

1. Librarian organizes documentation
2. Librarian uses master-index-updater skill
3. Master Index updated with new feature
4. Documentation becomes discoverable

Validation Rules

Before Adding Entry

• Feature documentation exists
• Domain is correct (Core/​Events/​Content/​Operations)
• No duplicate entries
• All documentation links valid
• Key files paths accurate

After Adding Entry

• Entry appears in correct domain
• All links work
• Last Updated timestamp correct
• Navigation preserved
• Alphabetical order maintained (if applicable)

Common Issues

Issue: Wrong Domain Classification

Problem: Feature added to wrong domain Impact: Confusing navigation Solution: Move entry to correct domain, update related links

Issue: Broken Documentation Links

Problem: Links point to non-existent files Impact: Users can't find documentation Solution: Validate links before adding, fix broken links

Issue: Duplicate Entries

Problem: Feature added multiple times Impact: Confusing navigation Solution: Check for existing entry before adding

Issue: Stale Entries

Problem: Deprecated features not marked Impact: Users try to use old features Solution: Regular audit, mark deprecated features

Maintenance Tasks

Weekly

• Validate all links work
• Check for new features without index entries
• Update timestamps for modified features

Monthly

• Review deprecated features for removal
• Reorganize if domain structure changes
• Consolidate related features

Quarterly

• Complete navigation audit
• Update domain definitions
• Archive truly obsolete features

Remember: The Master Index is the entry point for all feature documentation. Without it, documentation is invisible. With it, every feature is discoverable, organized, and maintainable. This skill automates keeping it current.
