Decipher the traces etched in past sessions and resurrect them as reusable skills. crune is a static web dashboard and CLI tool that analyzes Claude Code session logs, providing session playback, analytics, a semantic knowledge graph, and skill synthesis.

Features

• Session Playback --- Turn-by-turn conversation replay with minimap navigation, tool call inspection, and subagent branch expansion
• Overview Dashboard --- Activity heatmap, project distribution, tool usage trends, duration distribution, model usage, and top edited files
• Semantic Knowledge Graph --- TF-IDF + Tool-IDF + structural features, Truncated SVD, agglomerative clustering, Louvain community detection, Brandes centrality (algorithm details)
• Tacit Knowledge --- Extracted workflow patterns, tool sequences, and pain points (long sessions, hot files)
• Session Summarization --- Automatic session summary and classification (no LLM required), enriched with /insights facets data when available
• Skill Synthesis --- Synthesize reusable skill definitions from the knowledge graph (algorithm details)
