Codex Session Patcher
Repair Codex CLI, Claude Code, and OpenCode session files after refusal dead-ends so you can resume multi-step agent work with optional security-lab context injection.
Overview
Codex Session Patcher is an agent skill for the Build phase that cleans refusal entries from agent session files and optionally injects security-lab prompts into tool configs.

- Cleans refusal responses from JSONL (Codex CLI, Claude Code) and SQLite (OpenCode) sessions for resume
- CTF and pentest prompt injection into profiles or workspaces to reduce refusals at the source
- Unified web UI with diff preview, multi-platform dashboard, and real-time logs
- Platform matrix covers Codex CLI, Claude Code, and OpenCode with per-platform injection targets
- Python-based lightweight installer via git clone workflow documented in SKILL.md
- Supports 3 agent platforms: Codex CLI, Claude Code, and OpenCode
Adoption & trust: 695 installs on skills.sh; 31 GitHub stars; 0/3 security scanners passed (skills.sh audits).
What problem does it solve?
Your Codex, Claude Code, or OpenCode session hit a refusal and now resume fails or loops because the stored transcript still contains blocking assistant content.
Who is it for?
Advanced solo builders maintaining long agent sessions on local machines who hit refusal artifacts and need a supported patch-and-resume workflow.
Skip if: Beginners on shared machines or anyone seeking to bypass safety policies on systems they do not own or lack authorization to test.
When should I use this skill?
Clean codex session refusals, patch AI refusal responses, resume codex session after refusal, or inject CTF prompts per SKILL.md triggers.
What do I get? / Deliverables
Cleaned session files let you resume the thread, and optional workspace or profile injection reduces repeat refusals during authorized security exercises.
- Patched session files ready for resume
- Diff-previewed replacements for refusal turns
- Updated tool profiles or workspaces when using injection
Recommended Skills
Journey fit
Session repair and tool-profile patching are build-time agent ergonomics while you iterate on long-running coding sessions. It manipulates agent session artifacts and workspace configs—not application feature code—so agent-tooling is the canonical shelf.
How it compares
Local session-file surgery and config injection—not an MCP server or cloud-hosted agent orchestrator.
Common Questions / FAQ
Who is codex-session-patcher for?
Experienced indie builders using Codex CLI, Claude Code, or OpenCode who manage their own session stores and authorized security lab setups.
When should I use codex-session-patcher?
During build/agent-tooling when resume breaks after a refusal, when patching claude code refusal sessions, or when injecting CTF prompts into codex per documented triggers.
Is codex-session-patcher safe to install?
It modifies local session and workspace files and can change model behavior via injected prompts; review the Security Audits panel on this Prism page and only use on machines and scopes you control.

# Codex Session Patcher > Skill by [ara.so](https://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. --- ## What It Does 1. **Session Cleaning** — Scans session files for refusal responses and replaces them with cooperative content so you can `resume` the session. 2. **CTF Prompt Injection** — Injects security-testing context into tool configs/profiles to reduce refusal probability at the source. 3. **Web UI** — Unified dashboard for multi-platform session management, diff preview, and real-time logs. ### Platform Support | Platform | Session Format | Session Cleaning | CTF Injection | |----------|---------------|-----------------|---------------| | Codex CLI | JSONL | ✅ | ✅ Profile + Global | | Claude Code | JSONL | ✅ | ✅ Workspace | | OpenCode | SQLite | ✅ | ✅ Workspace | --- ## Installation ```bash git clone https://github.com/ryfineZ/codex-session-patcher.git cd codex-session-patcher # CLI only (zero extra dependencies) pip install -e . # CLI + Web UI pip install -e ".[web]" cd web/frontend && npm install && npm run build && cd ../.. ``` --- ## CLI Usage ```bash # Dry run — preview what would be changed, no file modification codex-patcher --dry-run --show-content # Clean the most recent session (auto-detects Codex format) codex-patcher --latest # Clean all sessions codex-patcher --all # Target a specific platform codex-patcher --latest --format claude codex-patcher --latest --format opencode # Install CTF prompt injection codex-patcher --install-ctf # Codex profile mode codex-patcher --install-claude-ctf # Claude Code workspace codex-patcher --install-opencode-ctf # OpenCode workspace ``` --- ## Web UI Usage ```bash # Production ./scripts/start-web.sh # or uvicorn web.backend.main:app --host 127.0.0.1 --port 8080 # Development (hot reload, frontend + backend) ./scripts/dev-web.sh ``` Open `http://localhost:8080` — supports Chinese/English UI toggle. --- ## Configuration Shared config file: `~/.codex-patcher/config.json` ```json { "mock_response": "Understood.
