📝 Walkthrough

Walkthrough

This PR performs a comprehensive cleanup of the superpowers plugin ecosystem by removing Claude plugin configuration files, the superpowers CLI tool with its utilities, hook automation scripts, predefined brainstorming/planning commands, the code-reviewer agent, and Codex documentation. It simultaneously marks 14+ skill and test directories as orphaned via timestamp files.

Plugin & Configuration Removal .claude-plugin/marketplace.json, .claude-plugin/plugin.json, .github/FUNDING.yml	Deletes Claude plugin marketplace definition, plugin manifest with metadata (name, description, version, author, homepage, repository, license), and GitHub funding configuration.
Superpowers CLI Tool & Core Utilities .codex/superpowers-codex, lib/skills-core.js	Removes 267-line Node.js CLI script implementing find-skills, bootstrap, and use-skill commands; deletes 208-line skills-core module exporting extractFrontmatter, findSkillsInDir, resolveSkillPath, checkForUpdates, and stripFrontmatter utilities.
Superpowers Documentation .codex/INSTALL.md, .codex/superpowers-bootstrap.md	Removes installation instructions for Codex superpowers setup and comprehensive bootstrap/onboarding documentation covering tool usage, skill conventions, and workflows.

Orphaned Directory Markers .opencode/plugin/.orphaned_at, docs/plans/.orphaned_at, docs/windows/.orphaned_at, skills/*/.orphaned_at (12 subdirs), tests/*/.orphaned_at (5 subdirs)	Adds 19 timestamp marker files across skill directories (brainstorming, dispatching-parallel-agents, executing-plans, finishing-a-development-branch, receiving-code-review, requesting-code-review, subagent-driven-development, systematic-debugging, test-driven-development, using-git-worktrees, using-superpowers, verification-before-completion, writing-plans, writing-skills) and test directories (claude-code, explicit-skill-requests, opencode, skill-triggering, subagent-driven-dev) signaling deprecation/orphaning.

Old hooks and scripts we leave behind,
Timestamps mark the orphaned way,
A cleaner garden starts today! ✨

lib/skills-core.js:1

• This file is imported by .opencode/plugin/superpowers.js at line 13 (import * as skillsCore from '../../lib/skills-core.js'). Deleting this file will break the OpenCode plugin, causing it to fail at runtime when attempting to load. The plugin uses multiple functions from this module including resolveSkillPath, stripFrontmatter, findSkillsInDir, and extractFrontmatter. Either the OpenCode plugin needs to be updated to inline these functions or this file should not be deleted.
