Ctrlb-decompose: Strip the noise from logs before sending to LLMs
Summary
This article presents ctrlb-decompose, a CLI tool (also available as a WASM browser build and Rust library) that compresses log lines by stripping noise and extracting actionable patterns before sending data to LLMs. It describes a two-stage pipeline: CLP encoding to convert tokens into typed placeholders, and Drain3 clustering to group logtypes into patterns with wildcards. Outputs support human-readable, LLM-optimized markdown, or JSON, and the project includes a Claude Code plugin and an MIT license.
