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 | $0.00104 | $0.00549 |
| Opus 5 | $0.00052 | $0.00275 |
| Sonnet 5 | $0.00021 | $0.00110 |
| Haiku 4.5 | $0.00010 | $0.00055 |
Grade A, and why
minimal-implementation 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.
What it actually says
最小正确实现
核心规则
只做当前请求需要的最小正确修改。用户明确要求架构、长期扩展或全面重构时，才扩大设计范围；普通“优化”不自动等于全面重写。
决策阶梯
新增代码、规则、文件、辅助函数或抽象前，依次确认：
- 这件事是否真的需要存在？
- 项目中是否已有实现、模式、规则、脚本或工具？
- 能否复用现有结构？
- 标准库是否足够？
- 平台原生能力是否足够？
- 已安装依赖是否足够？
- 只有前面都不满足时，才添加最小实现。
在第一个满足请求的层级停止。
变更预算
编辑前写下最小影响面、验收检查和明确不改的相邻文件。若新增抽象不能消除真实重复、提高正确性或让验证确定化，就不要新增。
安全边界
- 不添加无必要的 fallback、依赖、抽象或无关重构。
- 不用吞异常、静默降级、旧产物或修改测试预期掩盖根因。
- 修复共享路径上的根因，不只修补可见症状。
- 保留现有命名、结构和风格，除非用户明确要求改变。
- 只读审计不修改文件；高风险写入必须确认精确目标和回滚方式。
输出契约
小任务简要报告改动和验证。中大型任务报告：
- 修改面和复用的现有实现；
- 验收证据；
- 有意未修改的范围；
- 残余风险或真正阻塞。
验证
不要把 exit code 或旧产物单独当作成功证据。优先使用新鲜的定向测试、validator、哈希、渲染结果或直接行为检查。
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.

minimal-implementation is a skill published in the GitHub repository ooooooooooooooooooop/agent-tools (2 stars, last pushed 3d ago), licensed MIT. It adds 104 tokens to every session and 549 once invoked, about $0.0005 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.
