description	Efficiently read and analyze pi agent session JSONL files. Use when asked to "read a session", "review a session", "analyze a session", "what happened in this session", "load session", "parse session", "session history", "go through sessions", or given a .jsonl session file path.

Read Pi Sessions

Parse pi session JSONL files into readable output. Sessions live in ~/.pi/agent/sessions/<project>/ as .jsonl files.

Step 1: Find the Session

ls -t ~/.pi/agent/sessions/*<project>*/*.jsonl | head -10

Step 2: Start with Table of Contents

Always start with toc to get a numbered map of the session:

uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path> --mode toc

This prints a compact numbered list of every user exchange with timestamps and tools used.

Step 3: Read the Conversation

Default mode — shows only user messages and assistant text responses. Tool calls are hidden but hinted at with [used: tool1, tool2].

# Full conversation (default mode)
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path>

# Specific range
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path> --offset 5 --limit 3

# Search for specific topic
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path> --search "error"

Step 4: Drill Into a Turn

See everything about a specific exchange — thinking, tool calls, tool results, costs:
