Codex Quick Install

codex plugin marketplace add waybarrios/opencode-power-pack --ref main
codex plugin add opencode-power-pack@opencode-power-pack

Start a new Codex session, open /plugins to confirm the installation, or invoke a workflow explicitly with $code-review, $feature-dev, $security-review, and the other bundled skills.

Pi Quick Install

pi install git:github.com/waybarrios/opencode-power-pack

Pi discovers the eleven skills declared by the package. Use pi list to verify the installation. For a project-local installation recorded in .pi/settings.json, add -l:

pi install git:github.com/waybarrios/opencode-power-pack -l

Why This Exists

Codex, OpenCode, and Pi read SKILL.md workflows, but many valuable Claude Code workflows originated as Claude-specific commands and agents. Copying those artifacts directly does not preserve their orchestration, permissions, or subagent behavior.

This package adapts the portable methodology into shared skills, registers feature-development specialist roles as read-only OpenCode subagents, lets Codex execute the same phase assignments with its native subagent workflow, and exposes all eleven skills as a Pi package. It ships immutable provenance for every upstream work.

It complements obra/superpowers, which provides process skills such as brainstorming, TDD, debugging, and plan execution.

What's Inside

Category	Skill	Purpose
Review	code-review	Multi-agent PR review with confidence filtering and reproduction scenarios
Review	security-review	Security-focused review with category coverage and exploit-path validation
Feature development	feature-dev	Seven-phase workflow from discovery through implementation and review
Feature development	code-explorer	Trace a feature across entry points, layers, state, and dependencies
Feature development	code-architect	Produce a file-level architecture and implementation blueprint
Feature development	code-reviewer	Adversarial review of a focused local change set
Design	frontend-design	Create distinctive interfaces with an accessibility and craft rubric
Authoring	mcp-builder	Design and build MCP servers in TypeScript or Python
Authoring	skill-creator	Create, test, and improve reusable SKILL.md workflows
Project memory	agents-md-improver	Audit project rules and propose targeted improvements
Project memory	agents-md-revise	Capture durable session learnings in project rules

code-explorer, code-architect, and code-reviewer are standalone skills and specialist roles used by feature-dev. OpenCode registers named least-privilege agents; Codex can carry out the same assignments with native subagents and can use matching custom agents when the user configures them.

Installation

Prerequisites

• Git
• One supported host:
  • OpenCode 1.18.7 or newer: https://opencode.ai
  • A current Codex CLI or Codex desktop environment with plugin support: https://developers.openai.com/codex/
  • A current Pi coding agent installation: https://pi.dev/

Codex CLI And Desktop

Add this repository as a marketplace, then install the plugin:

codex plugin marketplace add waybarrios/opencode-power-pack --ref main
codex plugin add opencode-power-pack@opencode-power-pack
codex plugin list --marketplace opencode-power-pack

Start a new Codex session after installation so the eleven bundled skills are loaded. Use /plugins to inspect the installed plugin or $ to select one of its skills explicitly. Codex plugin packaging follows the official plugin structure.

OpenCode From GitHub

opencode plugin --global "opencode-power-pack@git+https://github.com/waybarrios/opencode-power-pack.git"

Restart OpenCode after installation. OpenCode discovers each skill and creates its same-named slash command automatically.

To pin a published release, append its tag:

opencode plugin --global "opencode-power-pack@git+https://github.com/waybarrios/opencode-power-pack.git#<tag>"

OpenCode From A Local Clone

git clone https://github.com/waybarrios/opencode-power-pack.git ~/code/opencode-power-pack
opencode plugin --global "opencode-power-pack@git+file:///home/you/code/opencode-power-pack"

Use an absolute file:// URL adjusted for your operating system. The target directory must be a Git repository.

Pi From GitHub

pi install git:github.com/waybarrios/opencode-power-pack

Pi installs the Git package and loads the skills/ directory declared in package.json. Use -l to save it to project settings instead of user settings. See the Pi package documentation for source, update, filtering, and trust behavior.

Verify OpenCode

opencode debug skill
opencode debug agent code-explorer

The first command should include all eleven unprefixed skill names. The second should report a subagent with editing denied. In the TUI, ctrl+p should list /code-review, /feature-dev, /frontend-design, and the other skill-derived commands.

Verify Codex

codex plugin list --marketplace opencode-power-pack

The list should show opencode-power-pack as installed. Start a new session and explicitly select $code-review, $feature-dev, or another bundled skill for a first test.

Verify Pi

pi list

The package list should include the Git source for waybarrios/opencode-power-pack. Start a new Pi session after installation so its bundled skills are available.

Updating

For Codex:

codex plugin marketplace upgrade opencode-power-pack
codex plugin add opencode-power-pack@opencode-power-pack

Start a new session after the upgrade.

For Pi:

pi update git:github.com/waybarrios/opencode-power-pack

For an OpenCode GitHub installation:

opencode plugin --global --force "opencode-power-pack@git+https://github.com/waybarrios/opencode-power-pack.git"

Restart OpenCode after the command finishes. For a pinned installation, update the tag first. Local-clone users should run git pull in the clone and reinstall with the same git+file:// spec.

Uninstalling

For Codex:

codex plugin remove opencode-power-pack@opencode-power-pack

For Pi:

pi remove git:github.com/waybarrios/opencode-power-pack

For OpenCode, remove the opencode-power-pack@... entry from the plugin array in the config where it was installed, then restart OpenCode. There are no command symlinks or copied command files to remove.

Troubleshooting

Symptom	Cause	Fix
Codex cannot find the marketplace	Marketplace snapshot is missing or stale	Run codex plugin marketplace add waybarrios/opencode-power-pack --ref main, or upgrade the existing marketplace
Codex installed the plugin but skills do not appear	The current session predates installation	Start a new Codex session and inspect /plugins
Pi does not show the skills	Package is absent, disabled, or the session predates installation	Run pi list, inspect pi config, and start a new Pi session
Skills or commands do not appear	OpenCode is older than 1.18.7	Upgrade OpenCode, restart, and run opencode debug skill
Skills are missing from debug output	Plugin installation failed or its config entry is absent	Re-run opencode plugin --global --force <module-spec> and inspect the reported error
Specialist agents are missing	Stale plugin checkout	Force reinstall, restart, and run opencode debug agent code-explorer
Installation reports a Git error	Invalid URL, network failure, or inaccessible repository	Validate the source with git ls-remote <url>
A workflow is rushed or incomplete	The backing model skipped multi-stage instructions	Use a stronger model and inspect whether required subagent tools are available

Invocation

Codex exposes installed skills through $ mentions, OpenCode 1.18.7+ exposes each discovered skill as a same-named slash command, and Pi loads the workflows from the installed skills package:

/code-review
/security-review
/feature-dev
/code-explorer
/code-architect
/code-reviewer
/frontend-design
/mcp-builder
/skill-creator
/agents-md-improver
/agents-md-revise

Examples:

$code-review review the current branch against main
$feature-dev add a logout button to the topbar
/code-review --comment
/code-review review https://github.com/owner/repo/pull/449
/feature-dev add a logout button to the topbar
/security-review
/frontend-design pricing page, brutalist tone, single-screen

In OpenCode, an explicit command with the same name takes precedence over a skill-derived command.

How It Works

opencode-power-pack
|
+-- .codex-plugin/plugin.json
|   +-- packages all skills/ for Codex and compatible plugin surfaces
|
+-- .agents/plugins/marketplace.json
|   +-- exposes the repository as an installable Codex marketplace
|
+-- package.json
|   +-- declares skills/ as a Pi package for pi install
|
+-- .opencode/plugins/opencode-power-pack.js
|   +-- registers skills/ in config.skills.paths
|   +-- registers code-explorer as a read-only subagent
|   +-- registers code-architect as a read-only subagent
|   +-- registers code-reviewer with read-only Git commands
|
+-- skills/<name>/SKILL.md
|   +-- shared Codex/OpenCode workflow
|   +-- host-native invocation metadata
|   +-- immutable source and license metadata
|
+-- UPSTREAMS.json
    +-- repository, commit, path, blob, date, and adaptation type

Each SKILL.md is the single source for its workflow. The OpenCode plugin derives specialist-agent prompts from those files at startup. Codex loads the same skills from the plugin and follows feature-dev's specialist assignments with its native subagent workflow; installing a skill does not itself create a named custom agent.

The packaged agents deny edits, external network access, and nested tasks. code-reviewer additionally allows a narrow set of read-only Git commands.

Scope And Non-Goals

In scope	Out of scope
Portable Claude Code workflow methodology	Claude Code hook contracts
Codex, OpenCode, and Pi skills, invocation, and subagent orchestration	Proprietary or non-redistributable plugins
Licensed adaptations with immutable provenance	Automatic trust of third-party skill catalogs
Explicit permission boundaries and regression tests	Supporting OpenCode versions older than 1.18.7 or obsolete Codex plugin formats

Contributing

Contributions are welcome for:

• Improvements based on reproducible workflow failures
• Behavioral evaluations and adversarial fixtures
• Portable references and deterministic helper scripts
• New ports with a verified license and immutable upstream source

Before opening a PR:

npm test
npm run smoke:opencode
npm pack --dry-run

Live behavioral evaluation is opt-in, needs OPENCODE_EVAL_MODEL, and runs only from a source checkout:

OPENCODE_EVAL_MODEL=provider/model npm run eval:behavioral

See evals/behavioral/README.md for the replay, review, and acceptance workflow. Snapshots are content-addressed evidence from one reviewed model execution, not universal guarantees.

Every skill must use a lowercase hyphenated directory/name, provide a trigger-specific description, remain under 500 lines where practical, and record its exact upstream in UPSTREAMS.json.
