Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00086 | $0.01897 |
| Opus 5 | $0.00043 | $0.00949 |
| Sonnet 5 | $0.00017 | $0.00379 |
| Haiku 4.5 | $0.00009 | $0.00190 |
Grade A, and why
vhs-terminal-recorder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VHS Terminal Recorder
When to use
Use this skill only when vhs or Charmbracelet VHS is actually the right surface:
- user says
vhs, Charmbracelet VHS,.tape, terminal GIF, terminal recording, command-line screencast, or scripted terminal demo - docs need a reproducible recording of CLI behavior
- an existing VHS tape needs authoring, validation, rendering, or debugging
Do not use it for arbitrary desktop capture, browser product tours, video editing, or one-off interactive work that cannot be made deterministic. Use a video/screen-capture workflow instead when the subject is not a terminal.
Mental model
VHS runs a tape file in a pseudo-terminal and renders the terminal session to GIF, MP4, or WebM. Treat a tape like a small executable test:
- the tape must create or point at deterministic state
- commands shown to viewers should be short and intentional
- setup belongs behind
Hide/Show vhs validatechecks tape syntax but does not prove the commands workvhs <file>executes the tape and can mutate files, hit the network, or run project commands
This skill is not the VHS language reference. For exact syntax, generate or inspect live docs:
vhs --help
vhs manual
vhs new /tmp/example.tape
vhs validate /tmp/example.tape
Setup and verification
VHS is the Charmbracelet CLI from https://github.com/charmbracelet/vhs. Before depending on it, verify the local binary and help:
vhs --version
vhs --help
Use command-specific help for current flags:
vhs record --help
vhs validate --help
vhs publish --help
Rendering also depends on the local VHS render stack, especially ttyd and ffmpeg. If vhs validate passes but rendering fails before running the tape, check those binaries before changing tape logic.
If vhs is missing and the user wants it installed, prefer the upstream-supported package manager for the current machine. The common macOS/Linux path is:
brew install vhs
For Windows, Arch, Nix, Docker, Debian/RPM packages, or Go source installs, use the upstream installation section instead of copying commands from memory: https://github.com/charmbracelet/vhs#installation
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vhs-terminal-recorder is a skill published in the GitHub repository tmchow/agent-skills (64 stars, last pushed 25d ago), licensed MIT. It adds 86 tokens to every session and 1,897 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
