superpowers VS gsd-2

Meanwhile, the ecosystem materialized. obra/superpowers shipped a complete software development methodology built on composable skills — 1,276+ stars and growing. The cobusgreyling/loop-engineering repo cataloged patterns from Osmani and Cherny into a practical reference.

Projects like Superpowers proved that agents can follow structured methodologies — brainstorm before coding, write tests before implementation, review against specs before declaring success. The skills are mandatory workflows, not suggestions. The agent checks for relevant skills before any task.

If you're looking for complementary skills and plugins then have a look at Addy Osmani's Agent Skills or Superpowers, both provide essential coding assistant skills like Test-Driven Development (TDD). OpenSpec provides consistency, and your workflow can evolve around it.

Before any implementation, I plan. I use the brainstorming skill from Superpowers to think through the approach, then Grill Me - a separate skill that probes for contradictions, gaps, and missing assumptions, question by question. Once I'm satisfied, I save the result as a PRD and move to writing-plans (also from Superpowers), which produces a detailed implementation plan: class names, properties, architecture, tests.

These don't replace the spec; they govern how the agent acts on it. Superpowers uses guided Q&A to clarify intent, then runs sub-agents behind a verification-before-completion gate. GSD manages context in waves for solo developers. HVE Core runs an RPI loop: Research, Plan, Implement, Review.

> It would be extremely cool to be able to write one or two lines of prompt in my harness, and have a light model iterate with me a few times writing/proposing requirements, guidelines and explanations, refining the prompt until it's ready to be sent to the actual LLM.

I feel like the vast majority of AI-using coders already do this via skills suites like Superpowers (see /superpowers:brainstorming), no? https://github.com/obra/superpowers

I sometimes use Superpowers skills such as writing-plan and writing-spec. The Superpowers brainstorming skill stores design specs under docs/superpowers/specs/YYYY-MM-DD--design.md, and the writing-plans skill stores implementation plans under docs/superpowers/plans/YYYY-MM-DD-.md.

It seems there is a new version [1] - I'll try it out and see if it is better.

GSD has beautiful structure. Milestones, slices, tasks. Discipline is the user's job. The framework doesn't enforce it at the worker level.

I have been using this a lot lately and ... it's good.

Sometimes annoying - you can't really fire and forget (I tend to regret skipping discussion on any complex tasks). It asks a lot of questions. But I think that's partly why the results are pretty good.

The new /gsd:list-phase-assumptions command added recently has been a big help there to avoid needing a Q&A discussion on every phase - you can review and clear up any misapprehensions in one go and then tell it to plan -> execute without intervention.

It burns quite a lot of tokens reading and re-reading its own planning files at various times, but it manages context effectively.

Been using the Claude version mostly. Tried it in OpenCode too but is a bit buggy.

They are working on a standalone version built on pi.dev https://github.com/gsd-build/gsd-2 ...the rationale is good I guess, but it's unfortunate that you can't then use your Claude Max credits with it as has to use API.
