telagod/code-abyss

Injects custom system prompts and 56+ security engineering knowledge bases into Claude Code and Codex CLI through a single command, with 4 switchable output styles (cultivator, concise, command, ritual) that control persona intensity and formatting. The installer detects existing auth (API keys, official login, custom providers), auto-merges settings.json while preserving user configs, and optionally installs the ccline status bar; uninstallation auto-restores backups. Skills are sourced from a unified registry where SKILL.md frontmatter generates both slash commands for Claude and custom prompts for Codex, eliminating manual maintenance across platforms.
