Terraphim Codex Skills Session Search

Session Search

Use this skill when searching through AI coding assistant history to find relevant past work, patterns, or context from previous sessions.

Overview

Terraphim provides unified session search across multiple AI coding assistants:

• Claude Code - Native session parsing from ~/.claude/projects/
• Cursor - IDE session history
• Aider - Git-based conversation logs
• OpenCode - Session history

Key Capabilities:

• Full-text search across messages
• Knowledge graph-enriched concept search
• Related session discovery
• Timeline visualization
• Export to JSON/Markdown

For Humans

Quick Start with REPL

# Build with session features
cargo build -p terraphim_agent --features repl-full --release

# Launch REPL
./target/release/terraphim-agent

# In REPL:
/sessions sources          # Detect available sources
/sessions import           # Import from all sources
/sessions search "rust"    # Search for "rust" in sessions
/sessions stats            # Show statistics

Session Commands Reference

Example Workflows

Find previous work on a topic:

/sessions search "authentication"
/sessions show abc123-def456

Discover patterns across projects:

/sessions import
/sessions stats
/sessions timeline --group week --limit 10

Find related solutions:

/sessions concepts "error handling"
/sessions related abc123 --min 3

CLI Usage

# Direct CLI search (without REPL)
terraphim-agent sessions search "database migration"

# Import and search in one pipeline
terraphim-agent sessions import && terraphim-agent sessions search "API design"

# Export specific session
terraphim-agent sessions export --session abc123 --format markdown --output session.md

For AI Agents

Detecting Session Capabilities

Check if sessions feature is available:

# Check if terraphim-agent has session support
if terraphim-agent sessions sources 2>/dev/null | grep -q "claude-code"; then
    echo "Session search available"
fi

Programmatic Usage (Rust)

use terraphim_sessions::{SessionService, ImportOptions};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Create service
    let service = SessionService::new();

    // Detect sources
    let sources = service.detect_sources();
    for source in sources {
        println!("{}: {:?}", source.id, source.status);
    }

    // Import sessions
    let options = ImportOptions::default().with_limit(100);
    let sessions = service.import_all(&options).await?;

    // Search
    let results = service.search("async rust").await;
    for session in results {
        println!("{}: {} messages",
            session.id,
            session.message_count()
        );
    }

    Ok(())
}

Knowledge Graph Enrichment

use terraphim_sessions::{SessionEnricher, EnrichmentConfig};

// Create enricher with automata
let config = EnrichmentConfig {
    thesaurus_path: "docs/src/kg/".into(),
    min_confidence: 0.8,
};
let enricher = SessionEnricher::new(config)?;

// Enrich session with concepts
let enriched = enricher.enrich(&session)?;

// Get matched concepts
for concept in enriched.concepts {
    println!("{}: {} occurrences",
        concept.term,
        concept.occurrences.len()
    );
}

// Find related sessions by shared concepts
let related = find_related_sessions(&sessions, &enriched, 3)?;

MCP Integration

Session search can be exposed via MCP tools:

{
  "tool": "session_search",
  "arguments": {
    "query": "error handling patterns",
    "limit": 10
  }
}

claude-log-analyzer Usage

For detailed session analysis:

use claude_log_analyzer::{Analyzer, Reporter};

// Analyze from default location
let analyzer = Analyzer::from_default_location()?;
let analyses = analyzer.analyze(None)?;

// Get agent usage statistics
for analysis in &analyses {
    for agent in &analysis.agents {
        println!("{}: {} invocations",
            agent.agent_type,
            agent.invocation_count
        );
    }
}

// Generate report
let reporter = Reporter::new();
reporter.print_terminal(&analyses);
