Code Search Tool Selector

This skill helps choose the most effective search tool for your task.

When Semantic Search Works Better

Claudemem provides better results for conceptual queries:

When Native Tools Work Better

Why Semantic Search is Often More Efficient

Token Efficiency: Reading 5 files costs ~5000 tokens; claudemem search costs ~500 tokens with ranked results.

Context Discovery: Claudemem finds related code you didn't know to ask for.

Ranking: Results sorted by relevance and PageRank, so important code comes first.

Example: Semantic Query

User asks: "How does authentication work?"

Less effective approach:

Copygrep -r "auth" src/
# Result: 500 lines of noise, hard to understand

More effective approach:

Copyclaudemem status  # Check if indexed
claudemem search "authentication login flow JWT"
# Result: Top 10 semantically relevant code chunks, ranked

Quick Decision Guide

Classify the Task

Step 2: Check claudemem Status (MANDATORY for Semantic)

Copy# ALWAYS run this before semantic search
claudemem status

Interpret the output:

Step 2b: If Not Indexed, Offer to Index

CopyAskUserQuestion({
  questions: [{
    question: "Claudemem is not indexed. Index now for better semantic search results?",
    header: "Index?",
    multiSelect: false,
    options: [
      { label: "Yes, index now (Recommended)", description: "Takes 1-2 minutes, enables semantic search" },
      { label: "No, use grep instead", description: "Faster but less accurate for semantic queries" }
    ]
  }]
})

If user says yes:

Copyclaudemem index -y

Step 3: Execute the Search

IF CLAUDEMEM IS INDEXED (from Step 2):

Copy# Get role-specific guidance first
claudemem ai developer  # or architect, tester, debugger

# Then search semantically
claudemem search "authentication login JWT token validation" -n 15

IF CLAUDEMEM IS NOT AVAILABLE:

Use the detective agent:

CopyTask({
  subagent_type: "code-analysis:detective",
  description: "Investigate [topic]",
  prompt: "Use semantic search to find..."
})

Tool Recommendations by Use Case

Native tools (Grep, Glob, find) work well for exact matches but provide no semantic ranking.

---

When Hooks Redirect to Claudemem

If a hook provides claudemem results instead of native tool output:

1. Use the provided results - They're ranked by relevance
2. For more data - Run additional claudemem queries
3. Bypass available - Use _bypass_claudemem: true for native tools when needed

The hook system provides claudemem results proactively when the index is available.

Task-to-Tool Mapping Reference

When Grep IS Appropriate

✅ Use Grep for:

• Finding exact string: grep -r "DEPRECATED_FLAG" src/
• Counting occurrences: grep -c "import React" src/**/*.tsx
• Finding specific symbol: grep -r "class UserService" src/
• Regex patterns: grep -r "TODO:\|FIXME:" src/

❌ Never use Grep for:

• Understanding how something works
• Finding implementations by concept
• Architecture analysis
• Tracing data flow
• Auditing integrations

Integration with Detective Skills

After using this skill's decision tree, invoke the appropriate detective:

Pre-Investigation Checklist

Before ANY code investigation task, verify:

• Ran claudemem status to check index
• Classified task as SEMANTIC or EXACT MATCH
• Selected appropriate tool based on classification
• NOT using grep for semantic queries when claudemem is indexed

Multi-File Read Optimization

When reading multiple files, consider if a semantic search would be more efficient:

Quick check before bulk reads:

1. Is claudemem indexed? (claudemem status)
2. Can this be one semantic query instead of N file reads?

Interception Examples

❌ About to do:

CopyRead src/services/auth/login.ts
Read src/services/auth/session.ts
Read src/services/auth/jwt.ts
Read src/services/auth/middleware.ts
Read src/services/auth/types.ts
Read src/services/auth/utils.ts

✅ Do instead:

Copyclaudemem search "authentication login session JWT middleware" -n 15

❌ About to do:

CopyGlob pattern: src/services/prime/**/*.ts
Then read all 12 matches sequentially

✅ Do instead:

Copyclaudemem search "Prime API integration service endpoints" -n 20

❌ Parallelization trap:

Copy"Let me Read these 5 files while the detective agent works..."

✅ Do instead:

CopyTrust the detective agent to use claudemem.
Don't duplicate work with inferior Read/Glob.

Efficiency Comparison

Tip: Claudemem results include context around matches, so you often don't need to read full files.

---

Recommended Workflow

1. Check index: claudemem status
2. Search semantically: claudemem search "concept query" -n 15
3. Read specific code: Use results to target file:line reads

This workflow finds relevant code faster than reading files sequentially.
