What codex-session-patcher does

The skill scans session files for refusal phrases and swaps them for a cooperative reply, after which the session can be resumed as usual. Formats differ: Claude CLI and Claude store JSONL, OpenCode uses SQLite.

Under the hood there is a Python library with a parser, a refusal detector and a patcher, plus the codex-patcher CLI and a web dashboard with diff preview and live logs. Run --dry-run first to see exactly what would change before anything is written. LLM rewriting is optional and needs a key for an Anthropic-compatible API, set through an environment variable rather than pasted into the config.

A second feature injects CTF context into tool profiles and workspaces to lower the chance of a refusal in the first place. For Claude CLI the profile activates only on an explicit codex -p ctf launch and leaves normal sessions alone. OpenCode has no profile mechanism, so you have to start it from the generated workspace. Editing session files rewrites your conversation history, so on a real project preview the diff before applying it.

What it helps with

  • clear a refusal from a session file and keep working
  • preview the diff before touching any file
  • rewrite a refusal with an LLM instead of a canned reply
  • add your own phrases to refusal detection
  • manage sessions from three tools in one dashboard

Example prompts for the agent

  • clean the latest Claude session and show me the diff
  • find refusals in my Claude session and replace them
  • install the CTF profile for Claude
