Codex Session Patcher

Skill by ara.so — Daily 2026 Skills collection.

A lightweight Python tool to detect and clean AI refusal responses from Codex CLI, Claude Code, and OpenCode session files, plus CTF/pentest prompt injection to reduce future refusals.

Skill by ara.so — 2026年度日常技能合集。

这是一个轻量级Python工具，可检测并清理Codex CLI、Claude Code和OpenCode会话文件中的AI拒绝响应，还支持注入CTF/渗透测试提示词以减少后续的拒绝情况。

What It Does

功能

Session Cleaning — Scans session files for refusal responses and replaces them with cooperative content so you can
```
resume
```
the session.
CTF Prompt Injection — Injects security-testing context into tool configs/profiles to reduce refusal probability at the source.
Web UI — Unified dashboard for multi-platform session management, diff preview, and real-time logs.

会话清理 — 扫描会话文件中的拒绝响应，替换为协作内容，方便你
```
resume
```
恢复会话。
CTF提示注入 — 将安全测试上下文注入到工具配置/配置文件中，从源头上降低拒绝概率。
Web UI — 统一仪表盘，支持多平台会话管理、差异预览和实时日志。

from codex_session_patcher.core.detector import RefusalDetector
from codex_session_patcher.core.patcher import SessionPatcher
from codex_session_patcher.core.formats import FormatStrategy

Auto-detect platform format

自动识别平台格式

strategy = FormatStrategy.detect() # or FormatStrategy("claude") / FormatStrategy("opencode")

Patch the session

修补会话

patcher = SessionPatcher(strategy, ai_enabled=False) result = patcher.patch_session(session, dry_run=True) # preview print(result.diff)

patcher = SessionPatcher(strategy, ai_enabled=False) result = patcher.patch_session(session, dry_run=True) # 预览 print(result.diff)

detector = RefusalDetector(
    custom_strong=["I cannot assist with hacking"],
    custom_weak=["this falls outside my guidelines"]

两级检测机制：

Strong phrases — full-text match (low false-positive)

强关键词 — 全文匹配（低误判率）

Weak phrases — match at start of response (avoids over-triggering)

弱关键词 — 仅匹配响应开头（避免误触发）

is_refusal, tier = detector.check_message("I cannot assist with this request.") print(is_refusal, tier) # True, "strong"

Common Patterns

常见使用场景

Batch Clean All Sessions with AI Rewrite

使用AI重写批量清理所有会话

Set API key, enable AI, clean everything

设置API密钥，启用AI，清理所有内容

export OPENAI_API_KEY="sk-..."

Edit config to enable AI

编辑配置启用AI

python -c " import json, pathlib cfg = pathlib.Path('~/.codex-patcher/config.json').expanduser() data = json.loads(cfg.read_text()) if cfg.exists() else {} data.update({'ai_enabled': True, 'ai_key': '${OPENAI_API_KEY}', 'ai_model': 'gpt-4o'}) cfg.parent.mkdir(exist_ok=True) cfg.write_text(json.dumps(data, indent=2)) print('Config updated') "

codex-patcher --all

undefined

codex-patcher --all

Use OpenRouter Instead of OpenAI

使用OpenRouter替代OpenAI

json

{
  "ai_enabled": true,
  "ai_endpoint": "https://openrouter.ai/api/v1",
  "ai_key": "${OPENROUTER_API_KEY}",
  "ai_model": "anthropic/claude-3.5-sonnet"
}

json

{
  "ai_enabled": true,
  "ai_endpoint": "https://openrouter.ai/api/v1",
  "ai_key": "${OPENROUTER_API_KEY}",
  "ai_model": "anthropic/claude-3.5-sonnet"
}

Use Local Ollama

使用本地Ollama

json

{
  "ai_enabled": true,
  "ai_endpoint": "http://localhost:11434/v1",
  "ai_key": "ollama",
  "ai_model": "llama3.1:8b"
}

json

{
  "ai_enabled": true,
  "ai_endpoint": "http://localhost:11434/v1",
  "ai_key": "ollama",
  "ai_model": "llama3.1:8b"
}

Preview Before Applying (Safe Workflow)

应用前预览（安全工作流）

bash

undefined

bash

undefined

Always preview first

始终先预览修改内容

codex-patcher --latest --dry-run --show-content

If happy with preview, apply

确认预览无误后再应用

codex-patcher --latest

Resume in Codex

在Codex中恢复会话

Troubleshooting

问题排查

Session not found

bash

undefined

找不到会话

bash

undefined

Check where sessions are stored per platform

检查各平台的会话存储路径

Codex: ~/.codex/sessions/

Claude Code: ~/.claude/projects/

OpenCode: SQLite DB in app data dir

OpenCode: 应用数据目录下的SQLite数据库

codex-patcher --dry-run # will report detected session paths


**OpenCode sessions not detected**
```bash

codex-patcher --dry-run # 会输出检测到的会话路径


**检测不到OpenCode会话**
```bash

OpenCode uses SQLite — ensure you launch from workspace

OpenCode使用SQLite存储 — 确保你从工作区启动

cd ~/.opencode-ctf-workspace && opencode codex-patcher --latest --format opencode


**AI rewrite not triggering**
```bash

cd ~/.opencode-ctf-workspace && opencode codex-patcher --latest --format opencode


**AI重写未触发**
```bash

Verify config has ai_enabled: true and valid endpoint/key

确认配置中ai_enabled为true，且endpoint/key有效

cat ~/.codex-patcher/config.json | python -m json.tool

Test API connectivity

测试API连通性

curl $AI_ENDPOINT/models -H "Authorization: Bearer $AI_KEY"


**CTF profile not taking effect in Codex**
```bash

curl $AI_ENDPOINT/models -H "Authorization: Bearer $AI_KEY"


**Codex中CTF配置文件未生效**
```bash

Must use -p flag explicitly

必须显式使用-p参数指定配置文件

codex -p ctf # CTF profile active codex # normal profile, no injection


**Restore accidentally patched session**
```bash

codex -p ctf # CTF配置生效 codex # 普通配置，无注入


**恢复意外修补的会话**
```bash

List backups

列出备份

python -c " from codex_session_patcher.core.patcher import SessionPatcher from codex_session_patcher.core.formats import FormatStrategy p = SessionPatcher(FormatStrategy.detect()) for b in p.list_backups('path/to/session.jsonl'): print(b.timestamp, b.path) "

Restore via CLI backup index

通过CLI备份索引恢复

codex-patcher --restore --backup-index 0


**Web UI frontend not loading**
```bash

codex-patcher --restore --backup-index 0


**Web UI前端无法加载**
```bash

Rebuild frontend

重新构建前端

cd web/frontend && npm install && npm run build && cd ../.. uvicorn web.backend.main:app --host 127.0.0.1 --port 8080

---

cd web/frontend && npm install && npm run build && cd ../.. uvicorn web.backend.main:app --host 127.0.0.1 --port 8080

---

Limitations

局限性

Cannot bypass platform-level hard safety policies — explicit policy violations may still be refused after patching.
Effectiveness varies with model version updates.
OpenCode CTF injection requires launching from the workspace directory (no profile mechanism).
After cleaning, always manually
```
resume
```
to restore conversation context.

无法绕过平台级的硬安全策略 — 明确违反政策的请求修补后仍可能被拒绝。
效果随模型版本更新会有差异。
OpenCode CTF注入需要从工作区目录启动（无配置文件机制）。
清理完成后，始终需要手动执行
```
resume
```
来恢复对话上下文。
