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 | $0.00237 | $0.02687 |
| Opus 5 | $0.00118 | $0.01344 |
| Sonnet 5 | $0.00047 | $0.00537 |
| Haiku 4.5 | $0.00024 | $0.00269 |
Grade A, and why
transform 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 2d 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.

Image Transform
Ferramentas para transformar e ajustar imagens: redimensionar, rotacionar, espelhar, recortar, trim, padding, ajustes visuais, filtros e conversão de formatos.
Usa Pillow + numpy em virtualenv isolado em ~/venvs/image-transform/.
Setup
Verificar se já está instalado
test -f ~/venvs/image-transform/bin/python && ~/venvs/image-transform/bin/python -c "import PIL; import numpy; print('OK')" || echo "PRECISA_INSTALAR"
Instalar (se necessário)
bash ${CLAUDE_PLUGIN_ROOT}/skills/transform/scripts/setup.sh
Uso
~/venvs/image-transform/bin/python ${CLAUDE_PLUGIN_ROOT}/skills/transform/scripts/transform.py INPUT [OPÇÕES]
Transformações podem ser combinadas numa única execução. A ordem de aplicação é: trim → resize → crop → pad → rotate → flip → ajustes → filtros.

What ships with it
2 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.

transform is a skill published in the GitHub repository hmaurus/masterclaude (2 stars, last pushed 1mo ago), licensed MIT. It adds 237 tokens to every session and 2,687 once invoked, about $0.0012 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.
