Gstack is a production-grade AI agent skill framework and headless browser automation toolchain designed for Claude Code, Codex, Cursor, and other coding agents. It provides a structured skill system (50+ slash-command skills like `/ship`, `/review`, `/plan-ceo-review`) with a resolver pipeline that generates per-host `SKILL.md` templates from TypeScript sources. The repo also contains a fully functional headless browser daemon (`browse/`) with anti-bot stealth, multi-layer prompt injection defense (canary tokens, ML classifiers, URL blocklist, envelope sentinel), CDP escape hatch, SOCKS5 proxy bridge, and secure file I/O. Additional subsystems include markdown-to-PDF generation (`make-pdf/`), iOS QA automation (`ios-qa/`), design mockup generation (`design/`), a secret redaction engine, and a cross-session knowledge base (gbrain). The codebase is unusually well-tested with extensive unit, integration, and periodic paid E2E tests against real LLM APIs. While primarily an application, it includes data pipeline components like telemetry aggregation, eval result stores, and a brain cache specification with TTL-based entities and calibration weights, making it a hybrid with strong data engineering discipline.
This repository is a Python-based CLI tool for exporting, importing, and managing Claude Code sessions. It allows users to export sessions from ~/.claude/projects/ to portable formats (JSONL, markdown, XML), import them to resume work in different environments, and create backups for safe recovery. The tool features both legacy export to ~/claude_sessions/exports/ and enhanced in-repo export to .claude-sessions/, with intelligent session detection, UUID regeneration preserving message threading, and pre-import snapshots for rollback capability. It includes hook scripts for automatic exporting and slash command integration for seamless workflow integration.
