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.
npx agentmods add instructions/fredericmn/coder-codex-gemini/claude-mdgit clone --depth 1 https://github.com/FredericMN/Coder-Codex-GeminiWhat it costs to keep this loaded
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 | $0.01438 | $0.01438 |
| Opus 5 | $0.00719 | $0.00719 |
| Sonnet 5 | $0.00288 | $0.00288 |
| Haiku 4.5 | $0.00144 | $0.00144 |
Grade A, and why
Coder-Codex-Gemini CLAUDE.md scanned grade A with 1 finding 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.

Expected in a hook, worth knowing in a rule or an instructions file.

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Coder-Codex-Gemini (CCG)
Claude + Coder + Codex + Gemini 多模型协作 MCP 服务器
项目定位
一个统一的 MCP 服务器,让 Claude (Opus) 作为架构师调度 Coder 执行代码任务、Codex 审核代码质量、Gemini 提供专家咨询,形成自动化的多方协作闭环。
核心价值
| 维度 | 价值 |
|---|---|
| 成本优化 | Opus 负责思考(贵但强),Coder 负责执行(量大管饱) |
| 能力互补 | Opus 补足 Coder 创造力短板,Codex 提供独立审核视角,Gemini 提供多元化专家意见 |
| 质量保障 | 双重审核机制(Claude 初审 + Codex 终审) |
| 全自动闭环 | 拆解 → 执行 → 审核 → 重试,无需人工干预 |
角色分工
Claude (Opus) → 架构师 + 初审官 + 终审官 + 协调者
Coder (可配置) → 代码执行者(生成、修改、批量任务)
Codex (OpenAI) → 独立代码审核者(质量把关)
Gemini (可选) → 多面手专家(架构设计、第二意见、前端/UI)

技术要点
MCP 工具
coder: 调用可配置后端模型执行代码生成/修改,默认workspace-writecodex: 调用 Codex 进行代码审核,默认read-onlygemini: 调用 Gemini CLI 进行专家咨询或代码执行,默认workspace-write
核心特性
结构化错误
失败时返回 error_kind 和 error_detail,便于上层决策是否重试:
{
"success": false,
"error": "错误摘要",
"error_kind": "timeout | upstream_error | ...",
"error_detail": {
"message": "错误简述",
"exit_code": 1,
"last_lines": ["最后20行输出..."],
"retries": 0
}
}
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.

Coder-Codex-Gemini CLAUDE.md is an instructions file published in the GitHub repository FredericMN/Coder-Codex-Gemini (181 stars, last pushed 7mo ago), licensed MIT. It adds 1,438 tokens to every session, about $0.0072 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
