LazyTail

What it does

LazyTail provides a high-performance terminal-based log viewer that allows AI assistants to search and analyze log files in real-time. It connects your project-local and global log directories to the AI, enabling complex queries and pattern analysis without manual copying.

Tools

• list_sources: Discover available logs from local and global directories.
• search: Find patterns using plain text, regex, or structured queries with context and filtering.
• get_tail: Retrieve the last N lines of a log with incremental polling.
• get_lines: Read specific line ranges from a log file.
• get_context: Get surrounding lines for a specific line number.
• get_stats: Analyze index metadata, severity breakdown, and ingestion rates.
