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 | $0.00000 | $0.00302 |
| Opus 5 | $0.00000 | $0.00151 |
| Sonnet 5 | $0.00000 | $0.00060 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
wave 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 yesterday.
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
wave
The starter skill. One tool, ten lines of handler: it plays the built-in wave
gesture, then speaks a greeting. Referenced by
examples/coach-leo/manifest.json and walked
through in the skills guide.
| Tool | Use it for |
|---|---|
waveAndGreet |
Wave + spoken greeting in one call |
Why it exists
Every skill bundle has the same four files (manifest.json, tools.json,
handlers.js, SKILL.md). This one is intentionally minimal so you can copy
the directory, rename the tool, and have a working custom skill in minutes. The
handler shows the two context calls most skills need:
await ctx.call('wave', {}); // dispatch any built-in or skill tool
await ctx.speak('Hello!'); // TTS through the agent's configured voice
Config
manifest.config.greeting sets the default line. Callers can override it per
call with the greeting argument.
Try it
Load Coach Leo (examples/coach-leo/) and ask him to say hi, or install the
skill on any agent and call the tool directly:
const el = document.querySelector('agent-3d');
await el.installSkill('/examples/skills/wave/');
What ships with it
3 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.

wave is a skill published in the GitHub repository nirholas/three.ws (110 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 302 tokens. 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 2026-09-03.
