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 | $0.00042 | $0.00565 |
| Opus 5 | $0.00021 | $0.00282 |
| Sonnet 5 | $0.00008 | $0.00113 |
| Haiku 4.5 | $0.00004 | $0.00056 |
Grade A, and why
codexguide-development 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
CodexGuide 开发规则
本 Skill 是 CodexGuide 的项目规则集合。每条规则都应保持极简、可迁移、可扩展，并写明触发场景、执行步骤和可检查的完成标准。
规则 1：文档迁移原则
当文档被移动、重命名、重排编号，或放入新的章节分组时，使用本规则。目标是迁移完成后，仓库看起来像内容本来就位于最终位置一样自然。
-
确定最终位置。
- 如果用户指定目标位置，按用户指定的位置处理。
- 如果用户未指定，根据当前文档结构判断最合适的章节。 完成标准：最终目录、文件名、所在顺序都已明确。
-
真正移动文档。
- 如果所在章节使用编号文件名，同步重命名文件，保持编号连续。
- 按需顺延或回退受影响的相邻文档。
- 周围章节使用编号时，不保留无编号的过渡文件。 完成标准：文件系统顺序与预期阅读顺序一致。
-
更新所有相关引用。
- 在仓库中搜索旧路径、旧 slug、标题和旧编号文件名。
- 若 Markdown 链接、README、导航、侧边栏、SEO 元数据、致谢页或索引页指向被移动内容，都要同步更新。 完成标准：仓库搜索不到指向旧文档路径的过期引用。
-
修复阅读链路。
- 更新被移动文档和受影响相邻文档底部的
下一步链接。 - 保持索引列表编号与文件名编号一致。 完成标准：从前一篇读到迁移文档，再读到后一篇时，顺序符合新的文档结构。
- 更新被移动文档和受影响相邻文档底部的
-
验证迁移结果。
- 先运行最小有效检查：优先搜索旧链接；可行时运行站点构建。
- 如果跳过某项检查，说明原因。 完成标准：验证结果已记录，剩余风险已说明。
扩展方式
后续项目规范按独立编号规则追加。每条规则只放一个清晰约束，避免把不同职责混在同一条规则里。
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.
- 2d ago First seen · 43 lines · 42 tokens per session scan A 3ab7af963426
codexguide-development is a skill published in the GitHub repository freestylefly/CodexGuide (3,343 stars, last pushed 4d ago), licensed MIT. It adds 42 tokens to every session and 565 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 2026-08-30.
