Key Innovation: Structural Understanding

v0.3.0 adds AST tree navigation with symbol graph analysis:

• PageRank ranking - Symbols ranked by importance (how connected they are)
• Call graph analysis - Track callers/callees for impact assessment
• Structural overview - Map the codebase before reading code

Quick Reference

# Always run with --nologo for clean output
claudemem --nologo <command>

# Core commands for agents
claudemem map [query]              # Get structural overview (repo map)
claudemem symbol <name>            # Find symbol definition
claudemem callers <name>           # What calls this symbol?
claudemem callees <name>           # What does this symbol call?
claudemem context <name>           # Full context (symbol + dependencies)
claudemem search <query>           # Semantic search with --raw for parsing
claudemem search <query> --map     # Search + include repo map context

Version Compatibility

Claudemem has evolved significantly. Check your version before using commands:

claudemem --version

Command Availability by Version

Version Detection in Scripts

# Get version number
VERSION=$(claudemem --version 2>/dev/null | grep -oE '[0-9]+\.[0-9]+\.[0-9]+' | head -1)

# Check if v0.4.0+ features available
if [ -n "$VERSION" ] && printf '%s\n' "0.4.0" "$VERSION" | sort -V -C; then
  # v0.4.0+ available
  claudemem --nologo dead-code --raw
  claudemem --nologo test-gaps --raw
  claudemem --nologo impact SymbolName --raw
else
  echo "Code analysis commands require claudemem v0.4.0+"
  echo "Current version: $VERSION"
  echo "Fallback to v0.3.0 commands (map, symbol, callers, callees)"
fi

Graceful Degradation

When using v0.4.0+ commands, always provide fallback:

# Try impact analysis (v0.4.0+), fallback to callers (v0.3.0)
IMPACT=$(claudemem --nologo impact SymbolName --raw 2>/dev/null)
if [ -n "$IMPACT" ] && [ "$IMPACT" != "command not found" ]; then
  echo "$IMPACT"
else
  echo "Using fallback (direct callers only):"
  claudemem --nologo callers SymbolName --raw
fi

Why This Matters:

• v0.3.0 commands work for 90% of use cases (navigation, modification)
• v0.4.0+ commands are specialized (code analysis, cleanup planning)
• Scripts should work across versions with appropriate fallbacks

The Correct Workflow ⭐CRITICAL

Phase 1: Understand Structure First (ALWAYS DO THIS)

Before reading any code files, get the structural overview:

# For a specific task, get focused repo map
claudemem --nologo map "authentication flow" --raw

# Output shows relevant symbols ranked by importance (PageRank):
# file: src/auth/AuthService.ts
# line: 15-89
# kind: class
# name: AuthService
# pagerank: 0.0921
# signature: class AuthService
# ---
# file: src/middleware/auth.ts
# ...

This tells you:

• Which files contain relevant code
• Which symbols are most important (high PageRank = heavily used)
• The structure before you read actual code

Phase 2: Locate Specific Symbols

Once you know what to look for:

# Find exact location of a symbol
claudemem --nologo symbol AuthService --raw

# Output:
# file: src/auth/AuthService.ts
# line: 15-89
# kind: class
# name: AuthService
# signature: class AuthService implements IAuthProvider
# exported: true
# pagerank: 0.0921
# docstring: Handles user authentication and session management

Phase 3: Understand Dependencies

Before modifying code, understand what depends on it:

# What calls AuthService? (impact of changes)
claudemem --nologo callers AuthService --raw

# Output:
# caller: LoginController.authenticate
# file: src/controllers/login.ts
# line: 34
# kind: call
# ---
# caller: SessionMiddleware.validate
# file: src/middleware/session.ts
# line: 12
# kind: call

# What does AuthService call? (its dependencies)
claudemem --nologo callees AuthService --raw

# Output:
# callee: Database.query
# file: src/db/database.ts
# line: 45
# kind: call
# ---
# callee: TokenManager.generate
# file: src/auth/tokens.ts
# line: 23
# kind: call

Phase 4: Get Full Context

For complex modifications, get everything at once:

claudemem --nologo context AuthService --raw

# Output includes:
# [symbol]
# file: src/auth/AuthService.ts
# line: 15-89
# kind: class
# name: AuthService
# ...
# [callers]
# caller: LoginController.authenticate
# ...
# [callees]
# callee: Database.query
# ...

Phase 5: Search for Code (Only If Needed)

When you need actual code snippets:

# Semantic search
claudemem --nologo search "password hashing" --raw

# Search with repo map context (recommended for complex tasks)
claudemem --nologo search "password hashing" --map --raw

Output Format

All commands support --raw flag for machine-readable output:

# Raw output format (line-based, easy to parse)
file: src/core/indexer.ts
line: 45-120
kind: class
name: Indexer
signature: class Indexer
pagerank: 0.0842
exported: true
---
file: src/core/store.ts
line: 12-89
kind: class
name: VectorStore
...

Records are separated by ---. Each field is key: value on its own line.

Command Reference

claudemem map [query]

Get structural overview of the codebase. Optionally focused on a query.

# Full repo map (top symbols by PageRank)
claudemem --nologo map --raw

# Focused on specific task
claudemem --nologo map "authentication" --raw

# Limit tokens
claudemem --nologo map "auth" --tokens 500 --raw

Output fields: file, line, kind, name, signature, pagerank, exported

When to use: Always first - understand structure before reading code

claudemem symbol

Find a symbol by name. Disambiguates using PageRank and export status.

claudemem --nologo symbol Indexer --raw
claudemem --nologo symbol "search" --file retriever --raw  # hint which file

Output fields: file, line, kind, name, signature, pagerank, exported, docstring

When to use: When you know the symbol name and need exact location

claudemem callers

Find all symbols that call/reference the given symbol.

claudemem --nologo callers AuthService --raw

Output fields: caller (name), file, line, kind (call/import/extends/etc)

When to use: Before modifying anything - know the impact radius

claudemem callees

Find all symbols that the given symbol calls/references.

claudemem --nologo callees AuthService --raw

Output fields: callee (name), file, line, kind

When to use: To understand dependencies and trace data flow

claudemem context

Get full context: the symbol plus its callers and callees.

claudemem --nologo context Indexer --raw
claudemem --nologo context Indexer --callers 10 --callees 20 --raw

Output sections: [symbol], [callers], [callees]

When to use: For complex modifications requiring full awareness

claudemem search

Semantic search across the codebase.

claudemem --nologo search "error handling" --raw
claudemem --nologo search "error handling" --map --raw  # include repo map
claudemem --nologo search "auth" -n 5 --raw  # limit results

Output fields: file, line, kind, name, score, content (truncated)

When to use: When you need actual code snippets (after mapping)

Code Analysis Commands (v0.4.0+ Required)

claudemem dead-code

Find unused symbols in the codebase.

# Find all unused symbols
claudemem --nologo dead-code --raw

# Stricter threshold (only very low PageRank)
claudemem --nologo dead-code --max-pagerank 0.005 --raw

# Include exported symbols (usually excluded)
claudemem --nologo dead-code --include-exported --raw

Algorithm:

• Zero callers (nothing references the symbol)
• Low PageRank (< 0.001 default)
• Not exported (by default, exports may be used externally)

Output fields: file, line, kind, name, pagerank, last_caller_removed

When to use: Architecture cleanup, tech debt assessment, before major refactoring

Empty Result Handling:

RESULT=$(claudemem --nologo dead-code --raw)
if [ -z "$RESULT" ] || [ "$RESULT" = "No dead code found" ]; then
  echo "Codebase is clean - no dead code detected!"
  echo "This indicates good code hygiene."
else
  echo "$RESULT"
fi

Static Analysis Limitations:

• Dynamic imports (import()) may hide real callers
• Reflection-based access not captured
• External callers (other repos, CLI usage) not visible
• Exported symbols excluded by default for this reason

claudemem test-gaps

Find high-importance code without test coverage.

# Find all test coverage gaps
claudemem --nologo test-gaps --raw

# Only critical gaps (high PageRank)
claudemem --nologo test-gaps --min-pagerank 0.05 --raw

Algorithm:

• High PageRank (> 0.01 default) - Important code
• Zero callers from test files (*.test.ts, *.spec.ts, *_test.go)

Output fields: file, line, kind, name, pagerank, production_callers, test_callers

When to use: Test coverage analysis, QA planning, identifying critical gaps

Empty Result Handling:

RESULT=$(claudemem --nologo test-gaps --raw)
if [ -z "$RESULT" ] || [ "$RESULT" = "No test gaps found" ]; then
  echo "Excellent! All high-importance code has test coverage."
  echo "Consider lowering --min-pagerank threshold for additional coverage."
else
  echo "$RESULT"
fi

Static Analysis Limitations:

• Test file detection based on naming patterns only
• Integration tests calling code indirectly may not be detected
• Mocked dependencies may show false positives

claudemem impact

Analyze the impact of changing a symbol using BFS traversal.

# Get all transitive callers
claudemem --nologo impact UserService --raw

# Limit depth for large codebases
claudemem --nologo impact UserService --max-depth 5 --raw

Algorithm:

• BFS traversal from symbol to all transitive callers
• Groups results by depth level
• Shows file:line for each caller

Output sections: direct_callers, transitive_callers (with depth), grouped_by_file

When to use: Before ANY modification, refactoring planning, risk assessment

Empty Result Handling:

RESULT=$(claudemem --nologo impact FunctionName --raw)
if [ -z "$RESULT" ] || echo "$RESULT" | grep -q "No callers found"; then
  echo "No callers found - this symbol appears unused or is an entry point."
  echo "If unused, consider running: claudemem --nologo dead-code --raw"
  echo "If entry point (API handler, main), this is expected."
else
  echo "$RESULT"
fi

Static Analysis Limitations:

• Callback/event-based calls may not be detected
• Dependency injection containers hide static call relationships
• External service callers not visible

LLM Enrichment Document Types (v0.2.0+)

Claudemem v0.2.0+ supports LLM-enriched semantic search with specialized document types.

Document Types

Navigation Mode

For agent-optimized search with document type weighting:

# Navigation-focused search (prioritizes summaries)
claudemem --nologo search "authentication" --use-case navigation --raw

# Default search (balanced)
claudemem --nologo search "authentication" --raw

Navigation mode search weights:

• symbol_summary: 1.5x (higher priority)
• file_summary: 1.3x (higher priority)
• code_chunk: 1.0x (normal)
• idiom: 1.2x (higher for pattern discovery)

Symbol Summary Fields

symbol: AuthService.authenticate
file: src/services/auth.ts
line: 45-89
behavior: "Validates user credentials and generates JWT token"
params:
  - name: credentials
    type: LoginCredentials
    description: "Email and password from login form"
returns:
  type: AuthResult
  description: "JWT token and user profile on success, error on failure"
side_effects:
  - "Updates user.lastLogin timestamp"
  - "Logs authentication attempt"
  - "May trigger rate limiting"

File Summary Fields

file: src/services/auth.ts
purpose: "Core authentication service handling login, logout, and session management"
exports:
  - AuthService (class)
  - authenticate (function)
  - validateToken (function)
patterns:
  - "Dependency Injection (constructor takes IUserRepository)"
  - "Factory Pattern (createSession)"
  - "Strategy Pattern (IAuthProvider interface)"
dependencies:
  - bcrypt (password hashing)
  - jsonwebtoken (JWT generation)
  - UserRepository (user data access)

Using Document Types in Investigation

# Find function behavior without reading code
claudemem --nologo search "processPayment behavior" --use-case navigation --raw

# Output includes symbol_summary:
# symbol: PaymentService.processPayment
# behavior: "Charges customer card via Stripe and saves transaction"
# side_effects: ["Updates balance", "Sends receipt email", "Logs to audit"]

# Find file purposes for architecture understanding
claudemem --nologo search "file:services purpose" --use-case navigation --raw

# Find anti-patterns to avoid
claudemem --nologo search "anti_pattern SQL" --raw

Regenerating Enrichments

If codebase changes significantly:

# Re-index with LLM enrichment
claudemem index --enrich

# Or enrich specific files
claudemem enrich src/services/payment.ts

Static Analysis Limitations

Claudemem uses static AST analysis. Some patterns are not captured:

Dynamic Imports

// NOT visible to static analysis
const module = await import(`./modules/${name}`);

Result: May show as "dead code" but is actually used dynamically. Action: Mark as "Potentially Dead - Manual Review"

External Callers

// Exported for external use
export function publicAPI() { ... }

Result: May show 0 callers but used by other repositories. Action: Use --include-exported carefully, or mark as "Externally Called - Manual Review Required"

Reflection/Eval

// NOT visible to static analysis
const fn = obj[methodName]();
eval("functionName()");

Result: Callers not detected. Action: Search codebase for eval, Object.keys, bracket notation.

Event-Driven Code

// NOT visible as direct callers
emitter.on('event', handler);
document.addEventListener('click', onClick);

Result: handler and onClick may show 0 callers. Action: Check for event registration patterns.

Dependency Injection

// Container registration hides relationships
container.register(IService, ServiceImpl);

Result: ServiceImpl may show 0 callers. Action: Check DI container configuration.

Scenarios

Scenario 1: Bug Fix

Task: "Fix the null pointer exception in user authentication"

# Step 1: Get overview of auth-related code
claudemem --nologo map "authentication null pointer" --raw

# Step 2: Locate the specific symbol mentioned in error
claudemem --nologo symbol authenticate --raw

# Step 3: Check what calls it (to understand how it's used)
claudemem --nologo callers authenticate --raw

# Step 4: Read the actual code at the identified location
# Now you know exactly which file:line to read

Scenario 2: Add New Feature

Task: "Add rate limiting to the API endpoints"

# Step 1: Understand API structure
claudemem --nologo map "API endpoints rate" --raw

# Step 2: Find the main API handler
claudemem --nologo symbol APIController --raw

# Step 3: See what the API controller depends on
claudemem --nologo callees APIController --raw

# Step 4: Check if rate limiting already exists somewhere
claudemem --nologo search "rate limit" --raw

# Step 5: Get full context for the modification point
claudemem --nologo context APIController --raw

Scenario 3: Refactoring

Task: "Rename DatabaseConnection to DatabasePool"

# Step 1: Find the symbol
claudemem --nologo symbol DatabaseConnection --raw

# Step 2: Find ALL callers (these all need updating)
claudemem --nologo callers DatabaseConnection --raw

# Step 3: The output shows every file:line that references it
# Update each location systematically

Scenario 4: Understanding Unfamiliar Codebase

Task: "How does the indexing pipeline work?"

# Step 1: Get high-level structure
claudemem --nologo map "indexing pipeline" --raw

# Step 2: Find the main entry point (highest PageRank)
claudemem --nologo symbol Indexer --raw

# Step 3: Trace the flow - what does Indexer call?
claudemem --nologo callees Indexer --raw

# Step 4: For each major callee, get its callees
claudemem --nologo callees VectorStore --raw
claudemem --nologo callees FileTracker --raw

# Now you have the full pipeline traced

Token Efficiency Guide

Optimal order: map → symbol → callers/callees → search (only if needed)

This pattern typically uses 80% fewer tokens than blind exploration.

Integration Pattern for Agents

For maximum efficiency, follow this pattern:

1. RECEIVE TASK
   ↓
2. claudemem --nologo map "<task keywords>" --raw
   → Understand structure, identify key symbols
   ↓
3. claudemem --nologo symbol <high-pagerank-symbol> --raw
   → Get exact location
   ↓
4. claudemem --nologo callers <symbol> --raw  (if modifying)
   → Know the impact radius
   ↓
5. claudemem --nologo callees <symbol> --raw  (if needed)
   → Understand dependencies
   ↓
6. READ specific file:line ranges (not whole files)
   ↓
7. MAKE CHANGES with full awareness
   ↓
8. CHECK callers still work

PageRank: Understanding Symbol Importance

PageRank measures how "central" a symbol is in the codebase:

Why PageRank matters:

• High-PageRank symbols are heavily used → understand them first
• Low-PageRank symbols are utilities → read later if needed
• Focus on high-PageRank symbols to understand architecture quickly

claudemem index

# Check status
claudemem --version && ls -la .claudemem/index.db 2>/dev/null

Framework Documentation (v0.7.0+) ⭐NEW

Claudemem v0.7.0+ includes automatic framework documentation fetching for your project dependencies. Documentation is indexed alongside your code, enabling unified semantic search across both.

Quick Reference

# Core documentation commands
claudemem docs status            # Show indexed libraries and cache state
claudemem docs fetch             # Fetch docs for all detected dependencies
claudemem docs fetch react vue   # Fetch specific libraries
claudemem docs providers         # List available documentation providers
claudemem docs refresh           # Force refresh all cached documentation
claudemem docs clear             # Clear all documentation cache
claudemem docs clear react       # Clear specific library cache

Documentation Providers

Claudemem uses a provider hierarchy with automatic fallback:

Dependency Detection

Claudemem automatically detects dependencies from:

Setup

# Option 1: Run init (includes docs configuration)
claudemem init

# Option 2: Configure Context7 manually (optional, for best coverage)
export CONTEXT7_API_KEY=your_key

# Get free API key at: https://context7.com/dashboard

Usage Examples

# Check current documentation status
claudemem docs status

# Output:
# 📚 Documentation Status
#
#   Enabled:     Yes
#   Providers:   Context7, llms.txt, DevDocs
#   Libraries:   12 indexed
#   Cache Age:   2h 15m
#
#   Indexed Libraries:
#     react (v18) via Context7 - 145 chunks
#     typescript (v5) via Context7 - 89 chunks
#     express (v4) via llms.txt - 34 chunks
#     ...

# Fetch documentation for all project dependencies
claudemem docs fetch

# Output:
# 📚 Fetching Documentation
#
#   [1/8] react... ✓ 145 chunks via Context7
#   [2/8] typescript... ✓ 89 chunks via Context7
#   [3/8] express... ✓ 34 chunks via llms.txt
#   [4/8] lodash... ✓ 67 chunks via DevDocs
#   ...

# Fetch specific library
claudemem docs fetch fastapi

# View available providers
claudemem docs providers

# Force refresh (clears cache, refetches)
claudemem docs refresh

Unified Search (Code + Documentation)

After indexing documentation, claudemem search returns results from both your codebase and framework documentation:

claudemem --nologo search "how to use React hooks" --raw

# Output includes:
# --- Your Code ---
# file: src/components/UserProfile.tsx
# line: 12-45
# kind: function
# name: useUserProfile
# score: 0.89
# content: Custom hook for user profile management...
# ---
# --- React Documentation ---
# library: react
# section: Hooks Reference
# title: useEffect
# score: 0.87
# content: The useEffect Hook lets you perform side effects...
# ---
# library: react
# section: Hooks Reference
# title: useState
# score: 0.85
# content: useState is a Hook that lets you add state...

When to Use Documentation Commands

Integration with Investigation Workflow

Add documentation fetch to your investigation workflow:

# ENHANCED Investigation Workflow (v0.7.0+)

# Step 0: Ensure framework docs are available (one-time)
claudemem docs status || claudemem docs fetch

# Step 1: Map architecture (now includes library patterns)
claudemem --nologo map "authentication" --raw

# Step 2: Search both code AND framework docs
claudemem --nologo search "JWT token validation" --raw
# Returns: your auth code + library docs on JWT handling

# Step 3: Understand how the library recommends usage
claudemem --nologo search "react best practices hooks" --raw
# Returns: your patterns + React official guidance

Version Information

The claudemem docs command requires v0.7.0+. Check your version:

claudemem --version
# Expected: 0.7.0 or higher

Note: If claudemem docs help returns "Unknown command", upgrade your claudemem installation.

Index Freshness Check (v0.5.0)

Before proceeding with investigation, verify the index is current:

# Count files modified since last index
STALE_COUNT=$(find . -type f \( -name "*.ts" -o -name "*.tsx" -o -name "*.js" -o -name "*.jsx" -o -name "*.py" -o -name "*.go" -o -name "*.rs" \) \
  -newer .claudemem/index.db 2>/dev/null | grep -v "node_modules" | grep -v ".git" | grep -v "dist" | grep -v "build" | wc -l)
STALE_COUNT=$((STALE_COUNT + 0))  # Normalize to integer

if [ "$STALE_COUNT" -gt 0 ]; then
  # Get index time with explicit platform detection
  if [[ "$OSTYPE" == "darwin"* ]]; then
    INDEX_TIME=$(stat -f "%Sm" -t "%Y-%m-%d %H:%M" .claudemem/index.db 2>/dev/null)
  else
    INDEX_TIME=$(stat -c "%y" .claudemem/index.db 2>/dev/null | cut -d'.' -f1)
  fi
  INDEX_TIME=${INDEX_TIME:-"unknown time"}
