Superpowers 5 is out, and it leans into a simple idea: if an agent is going to do more of the work, it should also shoulder more of the communication and process overhead that tends to slow down AI-assisted coding. The release centers on Visual Brainstorming, plus several workflow changes aimed at making plans more reliable, subagents more useful by default, and the overall pipeline a bit more disciplined.
Visual Brainstorming: getting out of ASCII art
The standout addition is Visual Brainstorming, a companion flow that lets an agent present interactive visuals in a browser—mockups, diagrams, comparisons, and other HTML-based artifacts—instead of trying to compress UI and UX discussions into terminal-friendly ASCII.
When the agent believes something should be shown visually, it prompts for permission and notes that the feature is still new and can be token-intensive. Under the hood, the system spins up a local web server that loads HTML written by the agent from disk, plus some client-side JavaScript to capture clicks and feedback as interaction happens in the browser.
The author describes using the feature with Claude running Superpowers 5 to clean up rendered webpages from Youtube2Webpage, with the agent directing attention back to the browser once it had a view worth reviewing. The same workflow also gets positioned as a better fit for brand and logo ideation—an example appears for Prime Radiant—where terminal diagrams tend to fall apart.
Visual Brainstorming is mostly tested in Claude Code and Codex, but is expected to work across most agents.
Spec Review: an adversarial loop for planning docs
Superpowers 5 also adds a spec review loop focused on a very practical failure mode: planning documents that quietly leave key decisions as “TBD” or “fill this in later.” After planning completes, Superpowers now launches a subagent to read the planning docs for sanity and completeness, acting as an adversarial reviewer.
It’s explicitly not presented as a substitute for a human glance at the spec, but the goal is to push planning docs toward being more execution-ready.
Subagent Driven Development becomes the default
Another major workflow shift: Subagent Driven Development is now the default when the host environment supports it. Previously, Superpowers offered a choice between that approach and a more manual workflow where execution happened chunk-by-chunk in a separate session.
In harnesses such as Claude Code that can pick different models for subagents, Superpowers 5 instructs the system to use the cheapest model capable of the task—with an example that Claude Haiku can often handle implementation when plans are sufficiently detailed. The tuning also includes better signaling when subagents are out of their depth and need help.
If a harness doesn’t support subagents, Superpowers warns that a subagent-capable harness performs better, then proceeds in a single session as best it can.
More explicit software engineering guidance through the pipeline
As projects scale, Superpowers 5 adds more structured guidance around unit decomposition and interface-driven design, wired through multiple stages:
- Brainstorming now emphasizes single-purpose units, clear interfaces, and independent testability, and treats large files as a design smell.
- Writing plans now includes a File Structure section before task decomposition.
- Implementation prompts instruct workers to follow the planned file structure and escalate if a file outgrows scope.
- Code review checks for single-responsibility violations and file size growth.
Brainstorming also starts identifying projects that look “too big” and works interactively to break them into manageable pieces.
Smaller but meaningful changes
A handful of operational updates round out the release:
- Documentation paths move from
docs/planstodocs/superpowers/specsanddocs/superpowers/plans. - Local instructions (from
CLAUDE.mdorAGENTS.md) are explicitly prioritized over Superpowers internal instructions to make customization simpler. - Codex subagent recursion mitigation addresses cases where subagents start delegating recursively after picking up the
using-superpowersskill. - Legacy /commands are deprecated in favor of native skills (with removal planned in a future release).
Superpowers 5 is available now on GitHub, and plugin-based harnesses like Claude Code or Cursor are expected to auto-update over the next day or two; direct installs may require a pull or reinstall.
