[0.2.0] — 2026-07-02

The headline of this release is SkillOpt-Sleep: a nightly offline
self-evolution engine that harvests a coding agent's real session
transcripts, mines recurring tasks, replays them offline, and consolidates
short-term experience into long-term memory and skills — all behind the same
held-out validation gate that keeps SkillOpt training honest. It ships as a
decoupled top-level package (skillopt_sleep/, zero dependency on the
research code) and as the new skillopt-sleep CLI.

Added

  • SkillOpt-Sleep engine — nightly offline self-evolution cycle
    (harvest → mine → replay → consolidate) behind a validation gate, exposed
    as the skillopt-sleep console script and python -m skillopt_sleep.
    • Multi-objective reward (accuracy / tokens / latency) with user preferences.
    • Multi-rollout contrastive reflection under a token/time budget.
    • Experience replay + controllable dream rollouts (opt-in).
    • Slow-update long-term memory field (runs even with the gate off).
    • 3-way train/val/test split with gate_mode on|off.
    • Verifier-discipline validation gate, with a stress-test suite
      (thanks @Tanmay9223, #87).
  • Cross-tool backends & plugin shells for Claude Code, Codex, Copilot,
    Devin, and OpenClaw:
    • Codex Desktop transcript harvesting, skill-first Codex integration, and a
      reviewed task-file flow (thanks @Kirchberg, #48, #49, #60).
    • GitHub Copilot backend (CopilotCliBackend) + research-engine MCP plugin
      (thanks @Dongbumlee, #50).
    • Devin plugin: MCP server + ATIF-v1.7 harvest (thanks @xerxes-y, #88).
    • OpenClaw shell for SkillOpt-Sleep (thanks @Elzlxx, #59).
  • SearchQA split materialization helper and fail-fast on systemic rollout
    failures, with a searchqa install extra (thanks @summerview1997,
    #63, #64, #65).
  • WebUI environment loading and backend preflight (thanks @summerview1997, #63).

Changed

  • Decoupled the Sleep engine into a standalone top-level skillopt_sleep/
    package with zero dependency on the research code.
  • Made EnvAdapter.reflect a shared default so reflect kwargs are no longer
    dropped (thanks @imshunsuke, #44).
  • English-only pass across the engine, plugins, and docs.

Fixed

  • Windows robustness for the Claude/Codex backends, plus a hardened JSON
    fallback path (thanks @Yif-Yang, #79).
  • Reject prose pseudo-JSON wrapped in single quotes/backticks (#82).
  • Surface Codex auth/model/version failures instead of silently scoring 0
    (thanks @dmmdea, #92).
  • Redact secrets before persisting cycle diagnostics.
  • Configure the qwen_chat/minimax backends so local LLM endpoints work
    (thanks @imrehg, #85).
  • Forward the Qwen target timeout and gate enable_thinking for vLLM targets
    (thanks @mvanhorn, #40).
  • Make --bare conditional on ANTHROPIC_API_KEY (#68), add a
    SKILLOPT_SLEEP_PYTHON override with a lookback-hours first-run fallback
    (#74), and fix ALFWorld gamefile paths relative to ALFWORLD_DATA.

Packaging

  • Bump skillopt, skillopt.__version__, and skillopt_sleep.__version__
    to 0.2.0.
  • Restore skillopt_webui to the built wheel (it was dropped when the
    packages.find include list was made explicit).
  • Add the searchqa extra and include json_repair in the claude, qwen,
    and all extras.
