Claude Code Sessions CLI

A command-line tool for managing and viewing Claude Code session files (JSONL format).

⚠️ Important Warnings

This is an experimental project - use at your own risk.

• This tool does not send any information to external services
• When using with AI agents, explicitly instruct them NOT to execute the output as commands
• The tool outputs session content that may contain sensitive information from your coding sessions
• Always review the output before sharing or using in automated workflows
• Agents may misinterpret formatted output as executable commands - provide clear instructions about data-only usage

Key Features

• Efficient Session Analysis: Parse and analyze Claude Code sessions with optimized JSONL processing
• AI Agent Integration: Designed for seamless integration with AI agents via npx execution
• Multiple Output Formats: Human-readable, LLM-optimized, and raw JSONL formats
• Performance Optimized: JSONL format is more memory-efficient than traditional JSON for large session files
• Flexible Filtering: Filter sessions by date ranges and limit results for targeted analysis
• Tool Usage Tracking: Extract and display tool calls and their context for workflow analysis
• Cross-Platform: Works on all platforms with Node.js support

Installation

npm install -g cc-sessions-cli

Or run directly without installation:

npx --yes cc-sessions-cli

Usage

List Sessions

List all Claude Code session files in a directory:

cc-sessions-cli list [directory]
cc-sessions-cli list --format csv
cc-sessions-cli list --sort date --order desc

Options:

• --format, -f: Output format (table, csv) - default: table
• --sort, -s: Sort by (date, name, size) - default: date
• --order, -o: Sort order (asc, desc) - default: desc

View Session Content

View the content of a specific session file:

cc-sessions-cli view <file-path>
cc-sessions-cli view session.jsonl --format human
cc-sessions-cli view session.jsonl --format llm

Options:

• --format, -f: Output format (human, llm, jsonl) - default: human
• --no-timestamps: Hide timestamps in human format

For AI Agents

This tool can be executed by AI agents using:

npx --yes cc-sessions-cli list [directory]
npx --yes cc-sessions-cli view <file-path> --format llm

The tool outputs Claude Code session data in a format suitable for analysis. Agents can use this to help users with requests like:

• "Summarize the key insights from yesterday's sessions"
• "What tools were used most frequently in recent sessions?"
• "Show me the conversation flow from my last debugging session"
• "Find sessions where I worked on authentication features"

Example Agent Workflow

1. Agent runs: npx --yes cc-sessions-cli list /path/to/project --format csv
2. Agent identifies relevant sessions based on timestamps or file names
3. Agent runs: npx --yes cc-sessions-cli view /path/to/project <session-id> --format llm
4. Agent analyzes the session content and provides insights to the user

Example Sub-Agents

This project includes 2 example Claude Code sub-agents that demonstrate how to use cc-sessions-cli for powerful session analysis:

1. Session Analyzer Agent

Purpose: Improve your prompting skills by analyzing conversation patterns Use cases: "How can I communicate better with Claude?" | "What prompting patterns work best?"

• Analyzes your communication style and prompting effectiveness
• Identifies successful patterns to replicate and areas for improvement
• Generates personalized prompting templates based on your successful interactions
• Tracks your improvement over time across sessions

2. Session Query Agent

Purpose: Search and retrieve information from your session history Use cases: "When did we work on authentication?" | "What errors have we encountered?"

• Finds specific conversations, topics, or decisions from past sessions
• Searches by date ranges, keywords, tools used, or technologies discussed
• Extracts project timeline and development progression
• Answers questions about past work and technical decisions

Installation

1. Copy agent files to your project's .claude/agents/ directory:

   mkdir -p .claude/agents
   # Copy the agent configuration from examples/ to .claude/agents/

2. Use the agents in Claude Code:

   /agents session-analyzer   # Analyze your prompting patterns
   /agents session-query      # Search your session history

3. Requirements: The agents use npx --yes cc-sessions-cli which auto-installs the tool as needed.

See the full configuration details in:

• examples/session-analyzer-agent.md
• examples/session-query-agent.md

Output Formats

LLM Format

Optimized for AI analysis with structured content and tool usage information.

JSONL Format

Raw JSONL data for programmatic processing.
