Orchestrate development work through sub-agents using td for state. Use when given a td task ID, text idea, markdown plan, or td epic to execute through plan-implement-review loops.
Set up and run autonomous overnight coding loops that process td epic tasks one at a time. Includes the loop runner, Rich TUI cockpit dashboard, and prompt template. Use when automating multi-day feature development across many tasks with td for state management.
Start a td review session and do a detailed review of open reviews. Fix obvious bugs immediately, create tasks for bigger issues, ensure test coverage, and use parallel subagents for independent reviews. Use when you want to review and triage pending td reviews.
Task management for AI agents across context windows. Use when agents need to track work, log progress, hand off state, and maintain context across sessions. Includes workflows for single-issue focus, multi-issue work sessions, and structured handoffs. Essential for AI-assisted development where context windows reset between sessions.
Create and maintain DESIGN.md files — a design system specification optimized for AI consumption. Use when creating a project's design system file, extracting tokens from existing CSS/code, auditing design consistency, or onboarding an agent to a project's visual language.
Write naturally and avoid AI-detectable patterns. Use when (1) generating any written content, (2) reviewing/editing text for AI-like patterns, (3) user asks to make writing sound more human/natural, or (4) improving text that sounds robotic or generic. Covers vocabulary, structure, tone, and formatting tells that signal AI authorship.

Use README.md for the authoritative syntax, options, and keys file format. Keep outputs reproducible and deterministic.
Launch any command in a tmux session with a hotkey bound to capture PNG screenshots on demand.
betamax capture <command> # capture with default settings
betamax capture nvim myfile.py # capture inside neovim
betamax capture --preset docs htop # use a named preset
betamax capture --theme dracula --shadow --window-bar colorful htop
Options:
--key KEY — capture hotkey in tmux format (default: C-g / Ctrl+G)--output-dir DIR — output directory (default: ./captures)--cols N / --rows N — terminal dimensions (default: current terminal)--preset NAME — load preset from ~/.config/betamax/presets/<name>.conf--save-text — also save raw ANSI text alongside PNG--window-bar STYLE — add window bar: colorful, colorful_right, rings--border-radius N, --margin N, --padding N — decoration geometry--shadow — enable drop shadow--theme NAME — color theme (dracula, nord, catppuccin-mocha, etc.)Config files (key=value, # comments):
.betamaxrc — project config (searched up to git root)~/.config/betamax/config — global config~/.config/betamax/presets/<name>.conf — named presets.keys file with @set:cols, @set:rows, and @set:output for consistent sizing.@require:termshot for PNG or @require:termshot + ffmpeg for GIFs.@wait/@sleep to reach the desired UI state before capture.betamax "<command>" -f path/to/file.keys.The same decoration flags from betamax capture work on the main command:
betamax myapp -f demo.keys --theme dracula --shadow --window-bar colorful
betamax myapp -f demo.keys --border-radius 10 --padding 10 --margin 20
CLI flags override @set: directives in the keys file, which override .betamaxrc config.
Precedence: CLI > @set: > .betamaxrc > global config > preset > defaults.
