Write or improve an LLM agent skill. Use when user says "create skill", "write a skill", "improve this skill", "new skill", "skill for X", or wants to build a SKILL.md file.
Pick the right model for a task and the right git strategy for the work. Use when about to dispatch a subagent, start a new feature, or unsure whether to use opus/sonnet/haiku/codex, or whether to branch/worktree/work direct. NOT for actually running the work - this only routes.
Generate a README in alxx's personal style. Use when user says "write a README", "create README", "readme for this project", "update README", or needs a repo README.
Architecture patterns from Crush, charmbracelet's production agentic coding CLI built on bubbletea v2, lipgloss v2, bubbles v2, glamour v2, and ultraviolet. Use when building production bubbletea apps, composing charm TUI components at scale, designing agentic CLI tools, implementing streaming LLM UIs, or asking about crush internals. NOT for individual charm library basics.

VHS records terminal sessions from .tape scripts. Requires ttyd and ffmpeg on PATH.
brew install vhs # also installs deps on macOS
vhs demo.tape # run a tape file
vhs new demo.tape # scaffold a new tape
vhs record > out.tape # record interactively, then exit
vhs publish demo.gif # host on vhs.charm.sh
Order matters: Output and Set must come before action commands. Require goes at the very top.
Require <program> # fail early if missing from PATH
Output <path> # .gif / .mp4 / .webm / .ascii / frames/
Set <Setting> Value # terminal config (must precede actions)
<actions> # Type, Enter, Sleep, etc.
Output demo.gif
Output demo.mp4
Output demo.webm
Output frames/ # PNG sequence
Output golden.ascii # for CI golden file diffing
Multiple Output lines are fine - all render in one run.

TypingSpeed is the only setting that can change mid-tape. All others are ignored after the first action command.

Wait is better than Sleep for commands with unpredictable runtime (builds, network calls).

Use the vhs-action GitHub Action to regenerate GIFs on push.
For integration testing, output .ascii and commit as golden files - diff them in CI to catch terminal output regressions.
