Session Analyzer

Extracts and analyzes your pi session transcripts to find recurring patterns that could be automated.

Usage

# Extract transcripts for current directory
{baseDir}/analyze.js

# Extract transcripts for specific directory
{baseDir}/analyze.js /path/to/project

# Match multiple dirs by pattern (worktrees, variants, etc.)
{baseDir}/analyze.js --pattern orders-app

# Extract + analyze with subagents
{baseDir}/analyze.js --analyze

# Pattern + analyze (finds all matching session dirs)
{baseDir}/analyze.js --pattern orders-app --analyze

# Custom output directory
{baseDir}/analyze.js --output ./my-analysis --analyze

What It Does

1. Extract: Reads all session files for the given working directory from ~/.pi/agent/sessions/
   • Use --pattern to match multiple directories (e.g., worktrees, feature branches)
2. Split: Chunks transcripts into ~100k char files (fits in context window)
3. Analyze (optional): Spawns pi subagents to identify:
   • AGENTS.md patterns: Coding style rules, conventions you repeat
   • Skill patterns: Multi-step workflows you do often
   • Prompt templates: Reusable prompts for common tasks

Output

Without --analyze:

session-transcripts/
├── session-transcripts-000.txt
├── session-transcripts-001.txt
└── ...

With --analyze:

session-transcripts/
├── session-transcripts-000.txt
├── session-transcripts-000.summary.txt  # Pattern analysis
├── session-transcripts-001.txt
├── session-transcripts-001.summary.txt
└── FINAL-SUMMARY.txt                    # Aggregated findings

Setup

Install dependencies (run once):

cd {baseDir}
npm install

When to Use

• After working on a project for a while, to discover what rules/skills would help
• Periodically to find new automation opportunities
• When you notice you keep giving similar instructions
