Process,
not just prompts.
From shower thought to shipped feature.
Mull is an opinionated engineering workflow layer on top of Claude Code. Ideas go in, pull requests come out.
Engineering discipline, automated.
Persistent memory
Context carries across sessions. No more re-explaining your codebase.
Plans before code
Every feature starts with a plan, not a prompt.
Automatic critique
Plans and code reviewed before anything ships.
PRs, not chat logs
Output is pull requests with tests, not conversation history.

One person, one license.
Two tiers. Both BYOK.
The Unix tool
- Persistent memory across sessions
- Task and idea tracking
- Plan → critique → review pipeline
- Worktree isolation per feature
The always-on system
- Everything in CLI
- Autopilot pipeline (hands-off planning)
- Always-on daemon
- Web dashboard
You bring the AI. Mull brings the engineering discipline.
From idea to merged PR
AI tools generate code. Mull enforces engineering.
"Add GitHub login to the app"
OAuth flow, user table migration, session handling, auth extractors, middleware
"Flash system is over-engineered. Org table is premature. CLI auth is out of scope."
Simplified. Scoped down. Focused.
Implementation opens — 1,968 lines across 14 files, 51 tests passing
"Missing cookie security flags. Session expiry on logout needs tightening."
Merged.
Two quality gates. Critique catches thinking problems — scope, architecture, over-engineering.
Review catches code problems — security, correctness, edge cases.
Both before anything ships.
Six steps. Every feature.
An opinionated workflow. Every feature goes through the same loop.
