Reads, searches and exports local OpenAI Codex history without continuing work: session inventory, timelines, verbatim user input, indexed search, and rollout identity/fork lineage. Use when the user asks what they told Codex, wants a Session ID, or evidence of what a run did. Not for Claude Code (use read-claude-code-history); with no platform named, start at local-conversation-history.
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
# Read Codex History Read Codex evidence only. Do not continue the old task or change its project. If the user wants execution after the read is complete, pass the verified evidence to `daymade-claude-code:continue-codex-work`. ## Find a complete thread ID first For a pasted UUID prefix or an identity-only request, run this bounded lookup: ```text python3 <skill-dir>/scripts/find_codex_session.py <UUID-prefix> ``` Accept only exit 0 with `status: unique` and `identity_verified: true`. The command queries matching state-index rows, includes archived/subagent entries, and verifies the unique candidate with the exact rollout locator. It does not export unrelated inventory, read conversation bodies, or probe writer locks. On ambiguity, show the returned candidates and ask for a longer prefix; on unavailable evidence, retain unknown. Return the verified ID and title, then stop. Load the rest of this Skill only for an additional requested result. Read [lookup and JSON contracts](references/session-lookup.md) only for exit handling, programmatic consumption or inventory JSON parsing. ## Codex history surfaces | Surface | Authority | Use | |---|---|---| …

How to install
mdr add daymade/claude-code-skills/read-codex-history@sha256:4b32436779ad5fceThe line at the top of this page pins the label git:20261104.a9b16a5, 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.
