SkillOpt-Sleep — Codex integration

Give your Codex agent a nightly sleep cycle: it reviews past sessions offline, replays your recurring tasks on your own Codex budget, and consolidates what it learns into validated memory + skills behind a held-out gate. Same engine as the Claude Code plugin (skillopt_sleep), wrapped for Codex.

Verified on Codex: on the public gbrain-evals skillopt-v1 benchmark, a deliberately deficient skill goes 0.00 → 1.00 on a held-out set with the Codex backend (incl. the tool-use seed via a real tool loop). See ../../docs/sleep/FINAL_REPORT.md.

What Codex supports (and what we use)

Codex (@openai/codex) extends via AGENTS.md instructions, skills at ~/.agents/skills/<name>/SKILL.md, and custom prompts at ~/.codex/prompts/<name>.md (invoked as /<name>). This integration ships all three, plus a shared runner.

Install

git clone <repo-url> SkillOpt-Sleep
cd SkillOpt-Sleep
bash plugins/codex/install.sh          # installs the /sleep prompt + skill
export SKILLOPT_SLEEP_REPO="$(pwd)"    # so the runner is found from anywhere

Requires Python ≥ 3.10 and the codex CLI on PATH.

Use

/sleep status      # what's happened
/sleep dry-run     # safe preview, stages nothing
/sleep run         # full cycle, stages a reviewed proposal (no live edits)
/sleep adopt       # apply the staged proposal (with backup)

Or call the engine directly:

python -m skillopt_sleep run --project "$(pwd)" --backend codex

Default backend is mock (no API spend). --backend codex uses your Codex budget for real improvement. All the controllable knobs (--gate on|off, --rollouts-k, --budget-tokens, --preferences, optimizer/target split) work identically — see ../../docs/sleep/CONTROLLABLE_DREAMING.md.

Notes / status

• Codex's exec runs shell, so the real-tool-loop replay (e.g. the tool_called: search benchmark seed) works natively.
• Codex's standalone plugin-package manifest format is not yet a stable public spec; this integration uses the documented AGENTS.md + skills + prompts mechanisms, which are stable. If/when a codex plugin package format ships, we'll add a one-file manifest.
