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 | $0.00045 | $0.00351 |
| Opus 5.5 | $0.00018 | $0.00140 |
| Sonnet 5.5 | $0.00009 | $0.00070 |
| Haiku 4.5 | $0.00005 | $0.00035 |
Grade A, and why
disposable-prototype 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 2mo 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
一次性原型
用最小隔离实验换取事实，不把探索代码伪装成可交付实现。
边界
- 不得启动 subagent，不得改变任务分类、模型选择、角色或质量门。
- 不得自行提交、发布或合并原型；只有用户明确要求保留时，才把原型作为独立资产处理。
- 不使用任何真实账户，不进行任何外部写入或破坏性副作用；需要外部系统时只用本地替身或静态样本。
- 不读取、请求或传递任何凭据，包括认证文件、环境变量、钥匙串、token cache 或原始会话数据库。
- 原型放在临时目录、项目既有 scratch 目录或明确指定的原型目录，不混入生产路径。
方法
- 先写一句原型要回答的问题，以及能区分成功和失败的观察证据。
- 选择最小实验面，只实现回答该问题所需的状态、接口或视觉差异。
- 实际运行并记录观察结果、限制和未覆盖条件。
- 给出生产决策输入；如果要进入正式实现，回到
cost-aware-development重新按风险分类、测试和验证，不直接复制原型当成成品。
讨论已经足以消除未知时，不创建原型。
What ships with it
1 file 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.

disposable-prototype is a skill published in the GitHub repository BottleYo/model-economy (6 stars, last pushed 1mo ago), licensed MIT. It adds 45 tokens to every session and 351 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 2026-08-31.
