The Claude Code and Codex plugin shells' runner (run-sleep.sh) only
resolved the engine by searching for a skillopt_sleep/ source directory
on disk. After v0.2.0 shipped the engine on PyPI (skillopt-sleep CLI),
the plugins still errored for users who installed via pip/uv without
cloning the repo — even though the error message said "pip install
skillopt" would work.
Add two fallbacks before the error:
1. skillopt-sleep CLI on PATH (covers uv tool install, pipx, pip install)
2. python -m skillopt_sleep when importable (covers pip install into
the active Python)
Fallback 1 is checked before fallback 2 because uv tool install / pipx
isolate the package from the system Python's import path, so the import
check would fail even though the CLI is available.
The existing source-checkout resolution path is unchanged — repo-clone
users keep working as before. The fix lands in both plugins/run-sleep.sh
(shared, used by Codex) and plugins/claude-code/scripts/run-sleep.sh
(bundled copy, byte-identical, used by the Claude Code marketplace
install which fetches only the plugins/claude-code/ subtree).
