What is morgan

A Claude Code plugin that bolts a process layer onto your day-to-day work. It puts an engineer with a code at your shoulder — one who insists you understand the problem before solving it, decompose by what done actually means, and tell the truth about where the work stands.

You get a five-step cycle for normal work, five branches for when reality interrupts (research, debugging, incidents, pivots, UI verification), seven specialist agents with distinct roles, and thirteen reference docs of distilled engineering practice the skill loads as needed.

The lead persona is Arthur Morgan — disciplined, plainspoken, honest about what he sees, won't be pushed past his principles. Says "I don't know" before he'll guess.

Who's Arthur Morgan? The protagonist of Red Dead Redemption 2 (Rockstar Games, 2018). The voice we drew from is his journal: weary professional, plainspoken, principled, honest about mistakes. The persona is a writing device that gives the discipline a recognisable shape — you don't need to know the game to use the plugin.

Quick start

claude plugin marketplace add andreyblck/morgan
claude plugin install morgan@morgan

Verify:

claude plugin list
# Expect: morgan@morgan — Status: ✔ enabled

Restart any active Claude Code session for the new commands to appear in autocomplete. Then in any project:

/morgan:morgan

Loads the skill, prints the banner, glances at git state, surfaces relevant patterns from past /aftermath runs, proposes a next action.

Use the claude plugin CLI from your shell — not /plugin slash-commands inside a Claude session. The slash form is the in-session manager UI; arguments don't reach it cleanly.

How it works

The cycle

The default flow runs five commands in sequence. Each step seals the work so the next has something solid to build on.

┌──────────┐   ┌──────────┐   ┌──────────┐   ┌──────────┐   ┌──────────┐
│  /scope  │──▶│  /case   │──▶│  /pull   │──▶│  /clean  │──▶│  /camp   │
└──────────┘   └──────────┘   └──────────┘   └──────────┘   └──────────┘
   define        decompose       build         verify        hand off

/scope produces a sealed scope document. /case turns it into a work-item breakdown. /pull executes against the breakdown. /clean verifies against original intent. /camp writes the handoff.

The branches

When the cycle isn't enough — when something's missing, broken, or changing — reach for these:
