🚀 How It Works

Mode 1: @[/leader] — Smart Delegation

You → Leader → Agents → Report per phase → You approve → Next phase

Phase	Agent	Mode
📋 Planning	@[/planner]	Sequential
🏗️ Architecture + 🎨 Design	@[/architect] + @[/designer]	⚡ PARALLEL
💻 Development	@[/frontend-dev] + @[/backend-dev]	⚡ PARALLEL
🧪 QA & Fix	@[/qa-engineer]	Sequential
🚀 Launch	@[/devops] + @[/security] + @[/seo] + @[/docs]	⚡ PARALLEL

Mode 2: @[/quickstart] — Full Autopilot

One command, complete project. No approvals needed. Best for MVPs and prototypes.

🧠 Brain System

Every installation includes the Brain — a structured knowledge base that agents read at session start:

Brain File	Purpose
default_skills.md	Documents 13 default skills, usage guide, workflow wiring
skills_manifest.json	Lightweight index of ALL 893+ skills for lazy-loading
lifecycle.md	Session lifecycle: init, plan, work, checkpoint, handoff
platform_notes.md	Cross-platform guide: paths, shells, encoding, permissions
project_context.json	Project metadata template (tech stack, conventions, sprint)
agent_index.json	Agent role definitions and handoff protocol

The brain files reference the 13 default skills, allowing agents to automatically:

• Load context from previous sessions (brain-manager)
• Break tasks into atomic checklists (concise-planning)
• Apply platform-specific commands (powershell-windows / bash-linux)
• Debug proactively (debugger)
• Handle errors consistently (error-handling-patterns)
• Maintain clean code and semantic commits (clean-code, git-manager, commit)
• Lazy-load additional skills via skills_manifest.json (saves 40-60% tokens)

13 Default Skills (Always Installed)

Category	Skills
Memory & Context	brain-manager, journal-manager, context-manager, codebase-navigator
Planning & Quality	concise-planning, writing-plans, clean-code, debugger, error-handling-patterns
Version Control	git-manager, commit
Cross-Platform	powershell-windows, bash-linux

🧰 Token Optimization

Tool	What it does	Savings
Skills Manifest	Lightweight index — load full SKILL.md on demand	~50% tokens
Context Manager	Minifies code before AI sees it	~50% tokens
Context Router	Queries only relevant data from 34+ sources	~70% tokens
Diff Applier	Applies surgical patches instead of rewriting	~90% tokens

🚢 Publishing to PyPI

This package is published as gkt on PyPI. Publishing is automated via GitHub Actions.

Auto-Publish on Tag Push

1. Update the version in GravityKit/VERSION
2. Commit and push changes
3. Create and push a version tag:

git tag v3.2.1
git push origin v3.2.1
