Documentation Cleaner

Consolidate redundant documentation while preserving 100% of valuable content.

Core Principle

Critical evaluation before deletion. Never blindly delete. Analyze each section's unique value before proposing removal. The goal is reduction without information loss.

Workflow

Phase 1: Discovery

1. Identify all documentation files covering the topic
2. Count total lines across files
3. Map content overlap between documents

Phase 2: Value Analysis

For each document, create a section-by-section analysis table:

Section	Lines	Value	Reason
API Reference	25	Keep	Unique endpoint documentation
Setup Steps	40	Condense	Verbose but essential
Test Results	30	Delete	One-time record, not reference

Value categories:

• Keep: Unique, essential, frequently referenced
• Condense: Valuable but verbose
• Delete: Duplicate, one-time, self-evident, outdated

See references/value_analysis_template.md for detailed criteria.

Phase 3: Consolidation Plan

Propose target structure:

Before: 726 lines (3 files, high redundancy)
After:  ~100 lines (1 file + reference in CLAUDE.md)
Reduction: 86%
Value preserved: 100%

Phase 4: Execution

1. Create consolidated document with all valuable content
2. Delete redundant source files
3. Update references (CLAUDE.md, README, imports)
4. Verify no broken links

Value Preservation Checklist

Before finalizing, confirm preservation of:

• Essential procedures (setup, configuration)
• Key constraints and gotchas
• Troubleshooting guides
• Technical debt / roadmap items
• External links and references
• Debug tips and code snippets

Anti-Patterns

Pattern	Problem	Solution
Blind deletion	Loses valuable information	Section-by-section analysis first
Keeping everything	No reduction achieved	Apply value criteria strictly
Multiple sources of truth	Future divergence	Single authoritative location
Orphaned references	Broken links	Update all references after consolidation

Output Artifacts

A successful cleanup produces:

1. Consolidated document - Single source of truth
2. Value analysis - Section-by-section justification
3. Before/after metrics - Lines reduced, value preserved
4. Updated references - CLAUDE.md or README with pointer to new location

Decision Rules

Use deletion only when all of these are true:

• The content is duplicated elsewhere or no longer accurate.
• The replacement location is clear and linked.
• No active workflow, script, or contributor guide depends on the old path.
• The user can review the before/after structure.

Prefer consolidation when documents contain overlapping but non-identical procedures. Prefer archival when the content is historically useful but no longer operational. Prefer leaving content in place when ownership, accuracy, or downstream references are uncertain.

Verification Commands

After cleanup, run project-appropriate checks:

rg "old-document-name|old/path" .
rg "TODO|TBD|placeholder" docs README.md

For documentation sites, also run the site build or link checker when available. Report both the reduction achieved and the content that was intentionally preserved.

Review Notes

Documentation cleanup should be reversible until the user accepts the new structure. Prefer a small staged change when removing high-traffic docs: first add redirects or pointers, then remove duplicates after references are updated. If docs are generated, update the source template or generator instead of editing generated pages directly.

When the cleanup affects onboarding, run a quick reader test: can a new contributor still find setup, architecture, commands, troubleshooting, and ownership information within two clicks from the main README?
