Tool Overlap Analyzer

Analyze project tooling (agents, skills, commands, hooks, workflows) for overlap and optimization opportunities. Each tool type is compared only within its own category.

Step 0: Deduplication (Cross-Platform Copies)

Many projects distribute identical tools to multiple platform directories (e.g., agents/claude/, agents/opencode/, skills/agents/). These are intentional copies for distribution, not redundancy issues.

Before analysis, deduplicate by:

1. Identify platform directories:

   • */claude/, */opencode/, */gemini/ → platform-specific
   • skills/agents/ → may mirror agents/*/

2. Compare files with same name across platforms:

   • If content is identical (or near-identical) → treat as single tool
   • Keep one representative for analysis (prefer claude/ or first found)

3. Record deduplication:

   Deduplicated: code-architect.md
   - agents/claude/code-architect.md (analyzed)
   - agents/opencode/code-architect.md (skipped - identical)
   - skills/agents/code-architect.md (skipped - identical)
   

Important: Cross-platform copies are NOT overlap issues. Only compare unique tools within each type.

Step 1: Discovery

Scan the project for each tool type:

For each discovered tool, record:

• File path
• Name (from filename or frontmatter)
• First 20 lines (for coarse scan)

Step 2: Coarse Scan (Within Same Type Only)

For each tool type separately, compare tools using:

1. Name similarity - Similar names suggest overlap (e.g., git-commit vs commit-standards)
2. Keyword extraction - Extract key terms from first 20 lines
3. Purpose inference - Infer primary purpose from description/frontmatter

Flag pairs as "potentially overlapping" if:

• Name similarity > 60% (Levenshtein or semantic)
• Shared keywords > 3
• Similar inferred purpose

Step 3: Deep Analysis

For flagged pairs, read full content and analyze:

Overlap Score Calculation

Overlap Score = (Purpose × 0.4) + (Trigger × 0.2) + (Output × 0.25) + (Deps × 0.15)

Score Interpretation:
  90-100%  →  Duplicate (recommend: merge or remove)
  70-89%   →  High overlap (recommend: consolidate)
  50-69%   →  Moderate overlap (recommend: clarify boundaries)
  30-49%   →  Low overlap (recommend: document relationship)
  0-29%    →  Distinct (no action needed)

Step 3.5: Cross-Reference Analysis (Before Optimization)

Before recommending merges or removals, check if tools are referenced by other files:

Why This Matters

Tools often have inter-dependencies:

• Commands may reference Skills (e.g., see: skill-name)
• README files may list available tools
• Documentation may link to specific commands
• Other tools may call or reference the tool

How to Check

For each tool flagged for potential merge/removal, search for references:

# Search for tool name in entire project
grep -r "tool-name" --include="*.md" --include="*.yaml" --include="*.json"

# Common reference patterns to find:
# - Direct links: [link](./tool-name.md)
# - Command references: /tool-name
# - Skill references: skill: tool-name
# - Import/see-also: see: tool-name

Reference Categories

Include in Report

For each optimization recommendation, add:

**Cross-References Found:**
- `README.md:466` - Lists /tool-name in command table
- `commands/claude/README.md:91` - Command list entry
- `skills/other-skill/SKILL.md:15` - References as related

**Required Updates:** 3 files need updating before removal

Step 4: Report Generation

Generate report at docs/report/tool-overlap-analysis-{YYYY-MM-DD}.md

### Boundary Clarification Needed
[Tools that need clearer scope definition]

### Documentation Improvements
[Tools that need better relationship documentation]

Writing Style for Report

The report should be written in natural, readable prose:

• Use clear headings and subheadings
• Explain findings in context, not just list data
• Provide actionable recommendations
• Include reasoning for each suggestion
• Use tables for comparisons, prose for analysis
• Maintain professional but accessible tone

Example Analysis Output

### Skills: custom-skills-git-commit vs commit-standards

**Overlap Score: 78% (High)**

| Dimension | custom-skills-git-commit | commit-standards | Similarity |
|-----------|-------------------|------------------|------------|
| Purpose | Generate commits with custom workflow | Format commit messages | 85% |
| Trigger | "git commit", "commit changes" | "commit message", "format commit" | 70% |
| Output | Git commit executed | Commit message text | 75% |
| Dependencies | Git CLI | None | 60% |

**Analysis:**
Both skills address commit message generation, but `custom-skills-git-commit` includes
the full workflow (staging, committing, pushing) while `commit-standards` focuses
solely on message formatting according to Conventional Commits.

**Recommendation:**
Consider merging `commit-standards` into `custom-skills-git-commit` as the message
formatting module, or clearly document that `commit-standards` is the lightweight
option for users who only need message formatting.
