Terraphim Session Analyzer (tsa/cla)

A powerful Rust-based CLI tool for analyzing AI coding assistant session logs to identify agent usage patterns, tool chains, and development insights. Supports Claude Code, Cursor, Aider, Codex, and OpenCode.

Features

• Tool Usage Analysis: Track which tools are used most frequently across sessions
• Agent-Tool Correlation: Understand which AI agents use which tools
• Tool Chain Detection: Identify common sequences of tools used together
• Knowledge Graph Search: Semantic search across tool usage patterns
• Multiple Export Formats: JSON, CSV, Markdown, HTML, and terminal output
• Timeline Visualization: Interactive HTML timeline of tool usage
• Real-time Monitoring: Watch for new sessions as they're created
• Self-Analysis: Analyze how projects were built using Claude Code

cla timeline --output timeline.html                # Generate timeline

watch

Monitor for new sessions in real-time.

cla watch                                          # Watch default directory
cla watch --session-dir /custom/path              # Watch custom directory

tools

Analyze tool usage patterns (most powerful command).

# Basic analysis
cla tools                                          # All tools
cla tools --tool Bash                             # Filter by tool
cla tools --agent "code-editor"                   # Filter by agent

# Advanced analysis
cla tools --show-chains                           # Tool sequences
cla tools --show-correlation                      # Agent-tool matrix
cla tools --kg-search "deploy OR test"           # Knowledge graph search

# Sorting and filtering
cla tools --sort-by recent                        # Most recent first
cla tools --sort-by frequency                     # Most used first
cla tools --min-usage 10                         # Minimum usage count

# Export formats
cla tools --format json -o tools.json            # JSON
cla tools --format csv -o tools.csv              # CSV
cla tools --format markdown -o tools.md          # Markdown
cla tools --format html -o tools.html            # HTML

# Analyze specific session
cla tools ~/.claude/projects/YOUR-PROJECT-DIR/

Technical Details

Session Storage

Claude Code stores sessions in ~/.claude/projects/, with each project having:

• session.jsonl: Main session log
• artifacts/: Generated files
• Other metadata files

Analysis Approach

The tool uses:

1. Streaming JSON parsing for memory efficiency
2. Pattern matching for tool chain detection
3. Statistical analysis for correlation matrices
4. Knowledge graph for semantic search (with terraphim feature)

Features

• terraphim: Enable knowledge graph capabilities (optional)

Build without knowledge graph:

cargo build --release

Build with knowledge graph:

cargo build --release --features terraphim

Development

Running Tests

cargo test                                         # Run all tests
cargo test --features terraphim                   # With knowledge graph

Code Quality

cargo clippy                                      # Linting
cargo fmt                                         # Format code
