Architect Detective Skill

Version: 3.1.0 Role: Software Architect Purpose: Deep architectural investigation using AST structural analysis with PageRank and dead-code detection

Role Context

You are investigating this codebase as a Software Architect. Your focus is on:

•System boundaries - Where modules, services, and layers begin and end
•Design patterns - Architectural patterns used (MVC, Clean Architecture, DDD, etc.)
•Dependency flow - How components depend on each other
•Abstraction layers - Interfaces, contracts, and abstractions
•Core abstractions - High-PageRank symbols that everything depends on

Why `map` is Perfect for Architecture

The map command with PageRank shows you:

•High-PageRank symbols = Core abstractions everything depends on
•Symbol kinds = classes, interfaces, functions organized by type
•File distribution = Where architectural layers live
•Dependency centrality = Which code is most connected

Architect-Focused Commands (v0.3.0)

Architecture Discovery (use `map`)

bash

# Get high-level architecture overview
claudemem --nologo map "architecture layers" --raw

# Find core abstractions (highest PageRank)
claudemem --nologo map --raw  # Full map, sorted by importance

# Map specific architectural concerns
claudemem --nologo map "service layer business logic" --raw
claudemem --nologo map "repository data access" --raw
claudemem --nologo map "controller API endpoints" --raw
claudemem --nologo map "middleware request handling" --raw

Layer Boundary Discovery

bash

# Find interfaces/contracts (architectural boundaries)
claudemem --nologo map "interface contract abstract" --raw

# Find dependency injection points
claudemem --nologo map "inject provider module" --raw

# Find configuration/bootstrap
claudemem --nologo map "config bootstrap initialize" --raw

Pattern Discovery

bash

# Find factory patterns
claudemem --nologo map "factory create builder" --raw

# Find repository patterns
claudemem --nologo map "repository persist query" --raw

# Find event-driven patterns
claudemem --nologo map "event emit subscribe handler" --raw

Dependency Analysis

bash

# For a core abstraction, see what depends on it
claudemem --nologo callers CoreService --raw

# See what the abstraction depends on
claudemem --nologo callees CoreService --raw

# Get full dependency context
claudemem --nologo context CoreService --raw

Dead Code Detection (v0.4.0+ Required)

bash

# Find unused symbols for cleanup
claudemem --nologo dead-code --raw

# Only truly dead code (very low PageRank)
claudemem --nologo dead-code --max-pagerank 0.005 --raw

Architectural insight: Dead code indicates:

•Failed features that were never removed
•Over-engineering (abstractions nobody uses)
•Potential tech debt cleanup opportunities

High PageRank + dead = Something broke recently (investigate!) Low PageRank + dead = Safe to remove

Handling Results:

bash

DEAD_CODE=$(claudemem --nologo dead-code --raw)
if [ -z "$DEAD_CODE" ]; then
  echo "No dead code found - architecture is well-maintained"
else
  # Categorize by risk
  HIGH_PAGERANK=$(echo "$DEAD_CODE" | awk '$5 > 0.01')
  LOW_PAGERANK=$(echo "$DEAD_CODE" | awk '$5 <= 0.01')

  if [ -n "$HIGH_PAGERANK" ]; then
    echo "WARNING: High-PageRank dead code found (possible broken references)"
    echo "$HIGH_PAGERANK"
  fi

  if [ -n "$LOW_PAGERANK" ]; then
    echo "Cleanup candidates (low PageRank):"
    echo "$LOW_PAGERANK"
  fi
fi

Limitations Note: Results labeled "Potentially Dead" require manual verification for:

•Dynamically imported modules
•Reflection-accessed code
•External API consumers

Workflow: Architecture Analysis (v0.3.0)

Phase 1: Map the Landscape

bash

# Get structural overview with PageRank
claudemem --nologo map --raw

# Focus on high-PageRank symbols (> 0.01) - these are architectural pillars

Phase 2: Identify Layers

bash

# Map each layer
claudemem --nologo map "controller handler endpoint" --raw  # Presentation
claudemem --nologo map "service business logic" --raw       # Business
claudemem --nologo map "repository database query" --raw    # Data

Phase 3: Trace Dependencies

bash

# For each high-PageRank symbol, understand its role
claudemem --nologo symbol UserService --raw
claudemem --nologo callers UserService --raw  # Who depends on it?
claudemem --nologo callees UserService --raw  # What does it depend on?

Phase 4: Identify Boundaries

bash

# Find interfaces (architectural contracts)
claudemem --nologo map "interface abstract" --raw

# Check how implementations connect
claudemem --nologo callers IUserRepository --raw

Phase 5: Cleanup Opportunities (v0.4.0+ Required)

bash

# Find dead code
DEAD_CODE=$(claudemem --nologo dead-code --raw)

if [ -z "$DEAD_CODE" ]; then
  echo "No cleanup needed - codebase is well-maintained"
else
  # For each dead symbol:
  # - Check PageRank (low = utility, high = broken)
  # - Verify not used externally (see limitations)
  # - Add to cleanup backlog

  echo "Review each item for static analysis limitations:"
  echo "- Dynamic imports may hide real usage"
  echo "- External callers not visible to static analysis"
fi

3. Dependency Flow

code

Entry → Controller → Service → Repository → Database
                  ↘ Middleware (cross-cutting)

PageRank for Architecture

PageRank	Architectural Role	Action
> 0.05	Core abstraction	This IS the architecture - understand first
0.01-0.05	Important component	Key building block, affects many things
0.001-0.01	Standard component	Normal code, not architecturally significant
< 0.001	Leaf/utility	Implementation detail, skip for arch analysis

Anti-Patterns

Anti-Pattern	Why Wrong	Correct Approach
`grep -r "class"`	No ranking, no structure	`claudemem --nologo map --raw`
Read all files	Token waste	Focus on high-PageRank symbols
Skip `map` command	Miss architecture	ALWAYS start with `map`
Ignore PageRank	Miss core abstractions	High PageRank = important

Notes

•map is your primary tool - It shows architecture through PageRank
•High-PageRank symbols ARE the architecture - they're what everything depends on
•Use callers to see what depends on a component (impact of changes)
•Use callees to see what a component depends on (its requirements)
•Works best with TypeScript, Go, Python, Rust codebases
