Codex Session Patcher

Skill by ara.so — Codex Skills collection.

A Python tool for cleaning AI refusal responses from session files and injecting CTF/security testing prompts into AI coding assistants (Codex CLI, Claude Code, OpenCode).

Skill by ara.so — Codex Skills collection.

一款Python工具，用于清理会话文件中的AI拒绝响应，并向AI编码助手（Codex CLI、Claude Code、OpenCode）注入CTF/安全测试提示词。

What It Does

功能介绍

Session Cleaning: Scans session files for AI refusal responses and replaces them with cooperative content, allowing you to resume interrupted conversations.

CTF Prompt Injection: Injects security testing context at the configuration level to reduce refusal probability when doing CTF challenges, penetration testing, or reverse engineering.

Multi-Platform Support:

Codex CLI (JSONL format)
Claude Code (JSONL format)
OpenCode (SQLite format)

会话清理：扫描会话文件中的AI拒绝响应，将其替换为协作内容，让你可以恢复中断的对话。

CTF提示词注入：在配置层面注入安全测试上下文，降低在进行CTF挑战、渗透测试或逆向工程时AI拒绝响应的概率。

多平台支持:

Codex CLI (JSONL format)
Claude Code (JSONL format)
OpenCode (SQLite format)

config = Config()
print(config.get_config())  # Verify ai_enabled, ai_endpoint, ai_key

Test API manually:

bash

curl -H "Authorization: Bearer $OPENAI_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{"model":"gpt-4o-mini","messages":[{"role":"user","content":"test"}]}' \

Session format auto-detection fails

会话格式自动检测失败

Explicitly specify format:

bash

codex-patcher --latest --format codex
codex-patcher --latest --format claude-code
codex-patcher --latest --format opencode

显式指定格式:

bash

codex-patcher --latest --format codex
codex-patcher --latest --format claude-code

Or programmatically:

```python
from codex_session_patcher.core.backup import BackupManager

manager = BackupManager()
backups = manager.list_backups("~/.codex/sessions/session.jsonl")
manager.restore_backup("~/.codex/sessions/session.jsonl", backups[0]['path'])

cp ~/.codex/sessions/session.jsonl.backup.20240115_103000

Key Concepts

核心概念

Refusal Detection: Two-tier system (strong phrases + weak prefixes) to minimize false positives while catching common refusal patterns.

Format Strategies: Adapter pattern for different session formats (JSONL vs SQLite), allowing unified API across platforms.

CTF Prompt Injection: Platform-specific injection points:

Codex: Profile config (
```
~/.codex/profiles/ctf.json
```
)
Claude: Project workspace (
```
CLAUDE.md
```
)
OpenCode: Agent workspace (
```
AGENTS.md
```
)

AI Context Awareness: When AI cleaning is enabled, the patcher passes conversation context to generate relevant, in-character replacements rather than generic responses.

拒绝响应检测: 双层检测系统（强关键词短语+弱前缀），在捕获常见拒绝模式的同时尽量减少误判。

格式策略: 针对不同会话格式（JSONL与SQLite）的适配器模式，实现跨平台的统一API。

CTF提示词注入: 平台专属注入点:

Codex: 配置文件（
```
~/.codex/profiles/ctf.json
```
）
Claude: 项目工作区（
```
CLAUDE.md
```
）
OpenCode: Agent工作区（
```
AGENTS.md
```
）

AI上下文感知: 启用AI清理功能后，修复工具会传递对话上下文，生成相关且符合角色的替代响应，而非通用回复。
