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.

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 | $0.00056 | $0.00374 |
| Opus 5 | $0.00028 | $0.00187 |
| Sonnet 5 | $0.00011 | $0.00075 |
| Haiku 4.5 | $0.00006 | $0.00037 |
Grade A, and why
skin 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 4d 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.
What it actually says
Skin — Claude Code Visual Themes
Switch between visual skins that change terminal colors, ASCII banners, status line theme, Claude's personality/voice, and tool feedback sounds.
Usage
The user invokes this skill with /skin followed by an optional argument.
Behavior
/skin (no arguments) — List available skins
Run the following to list skins and show which is active:
~/.claude/skins/engine/skin-command-hook.sh <<< '{"prompt": "/skin"}'
Display the output to the user.
/skin <name> — Activate a skin
Run activate.sh with the skin name:
~/.claude/skins/engine/activate.sh <name>
After activation, tell the user the skin is active and mention they can set it as default with /skin default.
If the personality file exists at ~/.claude/skins/personalities/<name>.md, read it and adopt that voice for the rest of the session.
/skin reset — Deactivate and restore
Run deactivate.sh:
~/.claude/skins/engine/deactivate.sh
Tell the user the terminal has been restored.
/skin default — Set current as permanent default
Read the current skin from ~/.claude/skins/engine/current, then update ~/.claude/skins/engine/config.yaml to set default_skin to that value.
Tell the user which skin was set as default.
What ships with it
7 files 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.

skin is a skill published in the GitHub repository basicScandal/claude-skins (12 stars, last pushed 3mo ago), licensed MIT. It adds 56 tokens to every session and 374 once invoked, about $0.0003 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 2026-08-31.

echorune-radar
Reads live weather for any place on earth, including radar rendered as text characters instead of an image: current conditions, a short forecast, a 2-hour rain sparkline, and a character radar map with the measured motion of the echo. Use when the user asks about weather, temperature or a forecast somewhere, whether…
linear-tickets
Use Orca's Linear CLI through orca linear ... commands to read linked ticket context with orca linear issue --current --full --json, post completion updates, move work forward through Linear workflow states, attach PR/MR links with orca linear attach --current --url --title "PR/MR link" --json, and triage Linear tasks…
computer-use
Use Orca's computer-use CLI for OS/window-level inspection and input in visible local app windows. Use when a task must read or operate a native app or an external browser window (for example, Chrome, Edge, or Safari) or an app webview. Do not use for Orca's embedded browser or page-only browser automation. Use…
orca-emulator-android
Control an Android emulator / device from inside Orca using the orca CLI. Use for listing/booting AVDs, taps, swipes, typing, hardware buttons (incl. Back and Recents), rotation, app install/launch, runtime permissions, the accessibility tree, and logcat — driving a real adb-connected device or emulator.…
harbor
Run Terminal-Bench or any Harbor dataset with Ante as the agent, using the Harbor adapter in the ante repo's ante-harbor/ directory. Use when the user wants to benchmark Ante on Harbor or reproduce Ante's published eval results.
create-skill
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
