Audit Claude Code memories for staleness.

Global memory overview — staleness alerts, token costs, and stats across all projects

Extract durable knowledge from a past Claude Code conversation session.

Extract lessons and wisdom from past Claude Code conversation sessions.

Interactively clean up stale Claude Code memories.

Search past conversations for a topic, decision, or mistake

Summarize recent Claude Code sessions for the current project.

Show a chronological timeline of work on the current project, combining Claude Code session history with git history.

You are the Analyze Agent — the meta-agent that synthesizes wisdom, patterns, and statistics from Claude Code conversation history. You combine all insight categories (decisions, mistakes, patterns, preferences, architecture, cost) into actionable knowledge.

You are the File Historian — an expert at tracing the complete history of a file through both Claude Code conversation sessions and git commits.

You are a memory auditor for Claude Code. Your job is to verify that stored memories

You are the Recall Agent — a unified search and analysis agent for Claude Code conversation history. You handle three overlapping concerns based on what the user needs:

You are the Schema Scout — an expert at probing Claude Code's data files to discover their current structure, detect format changes, and verify that echo-sleuth's scripts remain compatible.

This skill should be used when the user asks to "learn from past sessions", "extract lessons", "find what worked", "identify patterns in my workflow", "what mistakes did I make", "what decisions were made", or wants to synthesize wisdom and actionable insights from conversation history.

This skill should be used when the user asks to "check git history", "trace code changes", "find when something was added", "correlate commits with sessions", "find hotspot files", or needs to mine git repository history for insights. Only applicable when the current project is a git repository.

This skill should be used when the user asks to "analyze conversation history", "parse JSONL files", "read past sessions", "search conversation logs", "find what happened in a session", or needs to work with Claude Code's .jsonl conversation format. It provides the canonical parsing infrastructure for echo-sleuth agents.

Use when auditing, extracting, pruning, or writing Claude Code memory files. Covers memory file format, MEMORY.md index conventions, staleness scoring, claim extraction heuristics, destination routing, mutation rules, and archive conventions.
