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 | $0.00048 | $0.00399 |
| Opus 5 | $0.00024 | $0.00199 |
| Sonnet 5 | $0.00010 | $0.00080 |
| Haiku 4.5 | $0.00005 | $0.00040 |
Grade A, and why
lab scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Cannonball 3D Lab
Use o launcher que acompanha esta skill. Resolva SKILL_DIR como o caminho absoluto
da pasta que contém este SKILL.md; não presuma onde o plugin foi instalado.
/lab
Quando a solicitação for somente /lab, execute imediatamente:
python3 "${SKILL_DIR}/scripts/lab.py"
Esse comando é idempotente: na primeira execução copia o aplicativo para
~/.cannonball/3d-lab, instala as dependências e inicia os serviços; nas seguintes,
reutiliza a instalação e abre http://localhost:5555. A invocação explícita /lab
é autorização para criar essa pasta e instalar as dependências npm dentro dela.
Não peça caminho, porta ou confirmação adicional. Não altere a porta: 5555 faz
parte do contrato do Lab. Informe o endereço ou o erro concreto devolvido pelo
launcher. Nunca exponha o servidor além de 127.0.0.1.
Operações adicionais
Use somente quando o usuário pedir expressamente:
python3 "${SKILL_DIR}/scripts/lab.py" status
python3 "${SKILL_DIR}/scripts/lab.py" stop
python3 "${SKILL_DIR}/scripts/lab.py" install
python3 "${SKILL_DIR}/scripts/lab.py" start --reinstalar
Uma reinstalação preserva a pasta anterior como backup. O pacote não inclui corpus, pesos do SF3D, outputs, caches ou credenciais; esses dados permanecem locais e fora da skill.
What ships with it
31 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.
- 5d ago First seen · 43 lines · 48 tokens per session scan A fd5ab87cee61
lab is a skill published in the GitHub repository harebeats/cannonball (11 stars, last pushed 6d ago), licensed MIT. It adds 48 tokens to every session and 399 once invoked, about $0.0002 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 2026-09-05.
