Safely scan, triage, quarantine, restore, and purge Codex session/history/state/memory artifacts for current repo, explicit roots, subrepos, Codex-home, or all sessions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codex Session Cleanup Use this explicit-only skill for Codex artifact hygiene from any directory. Default to a read-only scan that produces a JSON manifest and Markdown report. Quarantine is reversible cleanup; purge is irreversible cleanup. ## Safety Contract - Never delete directly. Quarantine first, purge later. - Never mutate during `scan`. - Never clean all sessions unless the user explicitly asks for all sessions. - Never move, ignore, rewrite, or delete active memory by default. Copy memory summaries and the memory registry into quarantine when cleanup runs. - Never inspect or mutate `auth.json`, `internal_storage/**`, or secret-like env files unless the user explicitly requests a separate security-reviewed workflow. - Stop on SQLite integrity failures, JSONL parse errors, checksum mismatch, ambiguous thread IDs, active/recent session risk, active jobs/goals, child spawn risk, stale manifests, or missing backups. ## First-Pass Workflow 1. Load only the references needed: - `references/artifact-model.md` for Codex file and DB layout. - `references/classifier-rules.md` for confidence, scope, and memory triage. …

How to install
mdr add bjornmelin/dev-skills/codex-session-cleanup@sha256:288ff10da9b9ff0eThe line at the top of this page pins the label git:20260728.3aaa44b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
