Show HN: Ctrlb-decompose: Strip the noise from logs before sending to LLMs
ctrlb-decompose Compress raw log lines into structural patterns with statistics, anomalies, and correlations. Turn millions of noisy log lines into a handful of actionable patterns — with typed variables, quantile stats, anomaly flags, and severity scoring. Structurally │ Encoding │ identical lines now produce the same "logtype." └──────┬───────┘ │ ▼ ┌──────────────┐ Tree-based similarity clustering (Drain3) groups │ Drain3 │ logtypes into patterns.
