They are not three interchangeable products: they operate at different layers and prescribe different amounts of process.
What each option is—and what it is not
| Option | What it is | What it leaves open |
|---|---|---|
| Superpowers | A complete software development methodology built from composable skills and instructions intended to make coding agents use them. Its documented workflow runs from design through implementation, review, and branch completion. | It is not merely a packaging format; it prescribes a default sequence of work. |
| Agent Skills in Codex | A format for reusable workflows, packaged as instructions, resources, and optional scripts. In Codex, plugins are the installable distribution unit for reusable skills and apps. | The format does not dictate a full software lifecycle. A skill may cover one task or encode part of a larger process. |
| Matt Pocock’s skills | A curated library of workflows, including engineering and general productivity skills. Its engineering examples cover issue triage, specifications, tickets, implementation, architecture improvement, and code review. | It is a collection of focused workflows rather than a single mandatory development methodology or a general-purpose skills format. |
That distinction is the quickest way to make sense of the comparison: Superpowers answers, “What process should the agent follow?” Agent Skills answers, “How can a reusable capability be packaged and loaded in Codex?” Pocock’s collection answers, “Which engineering workflows should be available, and how should they be invoked?”

How much of the development process do they prescribe?
Superpowers defines an end-to-end sequence
Superpowers documents a deliberately ordered path: brainstorm and validate a design, create a worktree after approval, write a detailed plan, implement through test-driven development, review against the plan, then verify and finish the branch. Implementation may use subagents or run inline. The project describes these workflows as mandatory, not optional suggestions. Superpowers project documentation
The project’s stated principles include test-driven development, systematic methods instead of ad hoc guesses, reducing complexity, and requiring evidence before making claims. Those are design commitments, not independent proof that the methodology improves outcomes.
#1 Best Overall
Agent Skills lets the author choose the scope
A Codex skill can be narrow, such as a repeatable task, or form one component of a broader workflow. The format does not require brainstorming, a worktree, TDD, or any other particular lifecycle step; those instructions would have to come from the skill’s author or another layer of the setup. OpenAI Codex: Build skills
Pocock’s workflows can be combined
Pocock’s repository offers separate workflows for stages such as triage, specification, ticket breakdown, implementation, architecture improvement, and review. A team can adopt selected practices rather than treating the collection as one fixed sequence. Some engineering flows depend on repository-specific configuration, so the available workflow menu does not mean every process is ready to run unchanged in every project. Matt Pocock’s skills repository
How does each approach get invoked?
Invocation affects how much control a developer has over when a workflow begins. Superpowers is designed to activate relevant mandatory workflows through its installed system, within its documented sequence. Codex Skills uses progressive disclosure: the agent initially sees each skill’s name, description, and path, then loads the full instructions when it decides a skill is relevant.

- User-invoked skills: the developer explicitly types a command; these are intended as orchestration and entry points.
- Model-invoked skills: the agent may select a practice when the task description fits, making them suitable for reusable disciplines that apply across tasks.
The trade-off is practical: explicit invocation makes the starting point clearer to the developer, while automatic selection can make a practice available without remembering a command. Automatic selection depends on the agent recognizing that the task matches the skill.
Rank #3
Portability and setup: what should teams expect?
Superpowers requires harness-specific installation
Superpowers documents installation for several coding-agent harnesses, including Codex, Claude Code, Cursor, and Gemini CLI. Its setup is separate for each harness, so supporting multiple environments means following the relevant installation route for each one. Superpowers project documentation
Codex Skills are documented for the Codex ecosystem
The Codex guide explains how skills and plugins work within Codex. That documentation establishes the Codex authoring and loading model; it should not be read as a promise that a Codex skill package works unchanged in every other agent harness. OpenAI Codex: Build skills
Pocock’s repository expects workflow configuration
Pocock’s README describes use across agent products and a configuration approach, but actual compatibility depends on both the skill metadata and the harness. Some engineering workflows ask a team to configure its tracker and domain documentation. The setup guide offers templates for GitHub, GitLab, and local Markdown, and a way to describe another tracker; that is configuration guidance, not evidence that every integration is turnkey. Pocock skills setup guide
If your practical question is whether the workflow is “hard locked to github,” whether you can use “GitLab / Jira,” or “what about Azure DevOps,” the documented answer is to choose and describe the tracker during setup. The guide names templates for GitHub, GitLab, and local Markdown, and permits teams to describe another tracker. It does not establish that every tracker has a ready-made template.
Best Value
Which approach fits your team?
| If your priority is… | Best fit to investigate | Why |
|---|---|---|
| Giving agents a default, end-to-end development process | Superpowers | Its documented path connects design, planning, implementation, review, and branch completion, with mandatory workflows. |
| Authoring and packaging reusable capabilities in Codex | Agent Skills | It provides the format and loading model; your team defines what each skill does. |
| Adopting selected engineering practices with explicit and automatic invocation options | Matt Pocock’s skills | The repository provides focused workflows and distinguishes user-invoked orchestration from model-invoked practices. |
Before choosing, decide how standardized you want the lifecycle to be and who should trigger each practice. A team that wants a single expected sequence may value Superpowers’ prescriptive structure. A team building its own agent capabilities may need the Codex skill format rather than a preselected process. A team looking for a menu of engineering workflows can assess Pocock’s skills, while accounting for its local setup requirements.
What the documentation can—and cannot—show
The project and product documentation describe intended workflows and mechanisms; they do not establish that one option produces better code, fewer defects, or faster delivery than another. There is no supported comparative outcome figure here. Treat the choice as a fit between process, invocation, portability, setup effort, and team preference—not as a proven performance ranking.
The older OpenAI skills catalog repository is marked deprecated and directs readers toward the Plugins repository for current examples. For Codex’s current skills model, use the current Codex skills guide rather than treating the old catalog as the current distribution authority. Deprecated OpenAI skills catalog README
