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 5.1 | $0.00055 | $0.00829 |
| Opus 5.5 | $0.00022 | $0.00332 |
| Sonnet 5.5 | $0.00011 | $0.00166 |
| Haiku 4.5 | $0.00006 | $0.00083 |
Grade A, and why
portrait-916 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 1mo 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
Portrait 9:16 — 人像生图画幅升格规则
生成人像（portrait）图片时，默认一律用 9:16 竖幅。这是实测结论，不是偏好。
核心规则
- 人像 → 9:16：
gpt-image-2用--size 1024x1792。不要用 3:4 直接出人像。 - 为什么：3:4 画幅下模型把人脸摊进更宽的画面，五官更扁、皮肤纹理更弱、"抓拍感"更差；9:16 对应手机竖屏自拍的真实取景，人脸占比和景深逻辑都更对。2026-09-12 kr-realism 任务实测：同风格下 3:4 出图（gen/probe 时期）人脸明显弱于 9:16 v4（见 rex-videos
.workspace/2026-09-12-kr-realism/对比记录）。 - 下游要 3:4 时：先 9:16 生成，再用 Python（Pillow）裁成 3:4，禁止直接 3:4 生成后凑合。
- 提示词里同步声明画幅：prompt 首句写
9:16 vertical ...，与--size 1024x1792保持一致。
尺寸对照（gpt-image-2 支持值）
| 画幅 | size | 用途 |
|---|---|---|
| 9:16 | 1024x1792 |
人像默认 |
| 1:1 | 1024x1024 |
头像/方形位、快速试 prompt |
| 16:9 | 1792x1024 |
横版场景/背景图 |
执行要点
- 执行器用
rexai-image-generation技能的 Python 版rexai-image.py（进度可见、超时 600s、熔断/内容策略自动重试）。 - 9:16 大尺寸出图常需 60-180s，属正常，勿中途 kill（job 在服务端继续跑，kill 会丢 job id 上下文）。
- 内容安全过滤是概率性的：同一 prompt 可能过可能拦；被拦时脚本自动重试，仍失败就替换高危措辞（实测 "one hand ... in foreground" 易拦，"leaning forward with hands on the bed edge" 稳定过）。
验证记录
- 2026-09-12：kr-realism 任务，ref-01 参考图拆解 → v4 prompt（9:16, 1024x1792）一次通过，8 项场景锚点全中，人脸立体度显著优于 3:4 对照图。

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.

portrait-916 is a skill published in the GitHub repository rexleimo/aios (61 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 829 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-14.
