Why These Plugins

Most plugins in the wild are vibe-coded in an afternoon and never touched again.

These are different.

Every command in this marketplace comes from real, daily usage. They've been refined over months of working with Claude Code — not as experiments, but as core tools in an actual development workflow.

• Curated — Only what survives daily use makes it here
• Updated — Continuously improved based on friction points
• Tested — Not "it worked once" — used hundreds of times across real projects
• Minimal — No bloat, no clever abstractions, just what works

Installation

1. Add the marketplace

/plugin marketplace add agentic-dev3o/devx-plugins

2. Install plugins

Use the interactive plugin browser:

/plugin

Or install directly:

/plugin install devx-git@devx-plugins
/plugin install devx-qa@devx-plugins

Plugins

devx-git

Git workflow automation for developers who commit often and want clean history.

/devx-git:ci

Conventional commits from staged changes. No more thinking about commit message format.

/devx-git:ci

What happens:

1. Analyzes your staged diff
2. Determines type (feat, fix, refactor, etc.), scope, and subject
3. Shows preview for your confirmation
4. Commits

Output:

feat(auth): add JWT token refresh endpoint
fix(api): resolve race condition in websocket handler
chore: update dependencies to latest versions

⚠️ GPG Signed Commits (macOS Sandbox)

If you use GPG commit signing with Claude Code's sandbox mode, GPG needs access to its Unix socket. Add this to your ~/.claude/settings.json:

{
  "sandbox": {
    "network": {
      "allowUnixSockets": [
        "~/.gnupg/S.gpg-agent"
      ]
    }
  }
}

This allows GPG to communicate with its agent while keeping git sandboxed. Only tested on macOS.

/devx-git:pr [base-branch]

Create GitHub pull requests with proper descriptions. Defaults to main.

/devx-git:pr
/devx-git:pr develop

What happens:

1. Verifies clean working tree
2. Analyzes all commits since base branch
3. Pushes branch if needed
4. Creates PR with summary (the why) and test plan
5. Returns the PR URL

devx-qa

Code quality tools for understanding and maintaining projects.

/devx-qa:explain [feature]

Architecture analysis with ASCII diagrams. No external dependencies.

/devx-qa:explain
/devx-qa:explain auth-flow

What happens:

1. Detects your stack (language, framework, tools)
2. Finds the entrypoint for the feature you specify
3. Generates ASCII state machine diagram
4. Generates ASCII sequence diagram
5. Lists key files with their roles

Output:

┌─────────────┐    success    ┌──────────────┐
│  PENDING    │──────────────►│  AUTHORIZED  │
└─────────────┘               └──────────────┘
       │                             │
       │ failure                     │ logout
       ▼                             ▼
┌─────────────┐               ┌──────────────┐
│   FAILED    │               │   EXPIRED    │
└─────────────┘               └──────────────┘

No mermaid. No external tools. Just ASCII that works everywhere.

/devx-qa:claudemd [full|quick]

Keep your CLAUDE.md in sync with codebase evolution.

/devx-qa:claudemd
/devx-qa:claudemd quick

What happens:

1. Finds your CLAUDE.md (or creates one)
2. Analyzes commits since last update
3. Detects new patterns, stack changes, architecture shifts
4. Proposes additions and removals in diff format
5. Asks for confirmation before applying

Your project memory stays current without manual maintenance.

Philosophy

Battle-tested — Every command exists because it solved a real problem, repeatedly. Nothing theoretical.

Opinionated — Conventional commits. Proper PR descriptions. ASCII diagrams. Decisions are made so you don't waste time configuring.

Honest — If something doesn't work well, it gets fixed or removed. No dead code, no abandoned features.

Minimal — No dependencies. No build steps. Just markdown that Claude understands.
