Developers create a skill extraction tool for Claude Code logs

The crune utility analyzes Claude Code session logs through a web panel or CLI. It processes history files stored locally in project folders.
The system applies TF-IDF and Tool-IDF algorithms to cluster data and construct a semantic knowledge graph. Based on this analysis, crune automatically generates ready-to-use SKILL.md files.
The extracted skills can be directly integrated into Claude Code, allowing for the reuse of successful scenarios. This automates routine actions without requiring manual instruction writing from scratch.

Claude’s Dynamic Workflows architecture
Claude’s workflows enter a new era of structured programming. Dynamic Workflows turn agents into a managed, deterministic pipeline with sub-agents debating code validity. The approach relies on cached checkpoints and disallows non-deterministic functions like random number generation for reliability.
