Summary by cubic

npx lazycodex-ai install now installs OmO for Codex, Claude Code, and Gemini by default. It keeps single-surface installs via --platform, adds --platform=all/--all-platforms aliases, and filters Codex-only flags on non-Codex targets.

• New Features

  • Default multi-install for Codex, Claude Code, and Gemini with one command.
  • New aliases: --platform=all and --all-platforms (also accepts all, multi, *); explicit --platform=<target> still installs a single surface.
  • Non-Codex installs drop Codex-only args (e.g., --codex-autonomous).
  • Dry-run shows one line per target; non-install commands still pass through to oh-my-openagent unchanged.

• Migration

  • To install a single surface: npx lazycodex-ai install --platform=codex|claude-code|gemini.
  • To force multi-install: --platform=all or --all-platforms.
  • No changes needed unless you passed Codex-only flags when targeting other platforms.

Thanks for the PR! Changes to LazyCodex land through oh-my-openagent — could you open this against omo-codex over there instead? PRs in this repository can't be merged.

This PR was closed because it changes source-code paths in this repository:

If you're working with a coding agent, prompt it like this:

I opened #75 ("Install all supported agent platforms by default") against code-yeongyu/lazycodex, but changes there land through code-yeongyu/oh-my-openagent, where the Codex implementation lives under packages/omo-codex. Read my original PR, then open an equivalent PR against code-yeongyu/oh-my-openagent. In the new PR body, link the original PR (#75), explain that it was first opened against lazycodex, and describe in detail what that PR changed and why.

[sisyphus-bot] Correction: LazyCodex is intentionally Codex-only. The multi-target default proposed here (Codex + Claude Code + Gemini) was ported to oh-my-openagent in #5766, but that was the wrong product boundary and is being reverted. LazyCodex install should stay scoped to Codex; other harness installers need their own explicit surfaces instead of riding on LazyCodex defaults.
