Is the Jup Architect skill free?

Yes. The skill itself is free from andrader/jup. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Jup Architect SkillProof Score?

8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 3/5.

How do I install Jup Architect?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Jup Architect with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Jup Architect

A real, well-grounded architecture-review rubric for the jup CLI's own codebase — but it only means anything if you're literally working inside the jup repo.

Test report

Verdict: Works with setup
Score: 8.4/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 562191c

Used as intended, inside the real jup repo, its Data Persistence focus area guided a real find: get_skills_lock() in src/jup/config.py silently swallows any parse exception and returns an empty SkillsLock(), which skills_lock_session() then persists back to disk on exit — a traceable path to silently wiping a user's real lockfile on any transient corruption. But the skill's own Deliverables section points at docs/superpowers/specs/ and docs/superpowers/plans/, directories that don't exist and aren't part of jup's actual documented workflow (AGENTS.md specifies backlog/roadmap.md instead) — stale copy-paste from a template, and outside the jup repo itself this skill is functionally inert.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Jup Architect does

An architecture-review checklist scoped entirely to the `jup` skill-sync CLI's own codebase (src/jup/commands, config.py, models.py, the ~/.jup lockfile) — covering modularity, idiomatic Typer usage, Pydantic type safety, error handling, and testability, with a process flow and deliverable targets. Triggers on requests to audit jup's technical debt or propose architectural changes for jup specifically; not a general-purpose codebase-review skill.

How to install Jup Architect

git clone https://github.com/andrader/jup
cd jup
mkdir -p ~/.claude/skills
cp -r skills/jup-architect ~/.claude/skills/jup-architect

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Jup Architect

/jup-architect A real, well-grounded architecture-review rubric for the jup CLI's own codebase — but it only means anything if you're literally working inside the jup repo.

It also activates on plain-language prompts like these:

Review src/jup/config.py and models.py for architecture issues
Audit jup's lockfile persistence logic for silent data loss bugs
Propose architectural changes for jup's command modularity
