StratosphereOS: a weightless 3-layer agentic OS. Ships lifecycle workflows, a first-party skill, on-demand external skills, and a one-command project installer.
Initializes session to avoid cold start by reviewing necessary project context from memory layer/protocol.
Concludes session by codifying progress, updating memory artifacts, and performing linting to ensure a seamless, state-aware resumption of work.
Compact the current conversation into a handoff document for another agent to pick up.
End-of-day maintenance routine to reconcile multi-session learnings and purge intermediate scratchpads.
Workflow to conduct market & competitive research for greenfield or domain-heavy features before concept framing. Routes by domain and depth.
Autonomous, token-optimized Test-Driven Development for minor fixes, isolated functions, and sub-tasks.
Generates interactive single-file HTML plans/matrices/micro-apps ONLY when human-facing and spatial layout/interaction structurally outperforms markdown. Defaults to markdown.

A weightless, 3-layer agentic operating system for building full-stack apps — packaged as an installable plugin for Claude Code and Google Antigravity. Install it once, run one command, and any project gets the StratosphereOS constitution, a durable memory layer, lifecycle workflows, and the right skill packs.
One source of truth → two plugins. Update the source, rebuild, and every project that updates the plugin gets your learnings.
Constitution (AGENT.md / CLAUDE.md / GEMINI.md) — the "Lean Architect" 3-layer rules: Workflows → Orchestration → Execution, with strict precedence and token-efficient, deterministic behavior.
🚀 The Agentic Workflow - slash commands for the whole dev lifecycle:
| Stage | Command | File | When to use | Reads | Produces |
|---|---|---|---|---|---|
| 0 | /0a_start-session | 0a_start-session.md | Begin any session | STATUS, relevant memory | synced context |
| 0 | /0b_stop-session | 0b_stop-session.md | End any session | session work | updated memory, lint, handoff |
| 0 | /0c_handoff | 0c_handoff.md | Hand to a fresh session | conversation | .tmp/handoff_* |
| 0 | /0d_nightly-consolidation | 0d_nightly-consolidation.md | End-of-day maintenance (AFK) | sessions, .memory/* | consolidation plan |
| 1 | /1a_research | 1a_research.md | Research domain (problem vs. competitive, quick vs. deep) | memory | docs/research/ |
| 1 | /1b_concept-framing | 1b_concept-framing.md | Frame a fuzzy idea | GLOSSARY, BACKLOG_MAP | discovery brief, [[G-xxx]] |
| 2 | /2a_write-prd | 2a_write-prd.md | Turn a brief into a PRD | brief, memory | PRD doc + parent issue |
| 2 | /2b_interface-design | 2b_interface-design.md | Design interface (UI or non-UI contract) | PRD | design blueprint / contract |
| 3 | /3a_create-issue | 3a_create-issue.md | Slice a PRD into work | PRD | vertical-slice issues |
| 3 | /3b_sprint-planning | 3b_sprint-planning.md | Sequence a sprint | BACKLOG_MAP | sprint plan |
| 3 | /3c_implement-issue | 3c_implement-issue.md | Build a slice (TDD) | issue, ARCHITECTURE, UX | code + tests |
| 4 | /4a_verify-and-ship | 4a_verify-and-ship.md | Verify a slice (AC↔test coverage), then open a traceable PR | issue, tests, design doc | gap report + PR |
| 4 | /4b_audit-architecture-drift | 4b_audit-architecture-drift.md | Find structural drift | target dir, .memory/* | .tmp/refactor-proposal.md |
Installer — /stratosphere-setup scaffolds the project: memory layer, workspace rules, constitution, and an interactive skill-pack setup. Safe to re-run (diff-aware) as an upgrade path.
First-party skills — micro-tdd (autonomous, token-efficient TDD) and plan-html (interactive HTML plans/matrices/micro-apps).
On-demand skills — database, React/web, React Native, and design packs are fetched only when a project needs them (see src/external-skills.json).
Design tooling: Google Stitch is the default design tool when enabled (
Stitch Status: yes); no-Stitch projects use reference-driven native design (Path B in2b_interface-design). Brand tokens live in.memory/DESIGN.md(Google LabsDESIGN.mdspec) and structural rules in.memory/DESIGN_RULES.md. The optionaldesignskill pack (impeccable) is polish on top, not a replacement.
StratosphereOS assumes a React + Tailwind + shadcn/ui UI stack by default. Non-UI features are handled by the Path C interface contract in 2b_interface-design. A project can adopt another stack by superseding DR-004/DR-005 (see memory-protocol.md §3) with explicit user confirmation.
New to agentic coding? The easiest way to install StratosphereOS is to let your AI agent do it. Open Claude Code or Google Antigravity and paste this one prompt into the chat:
Install StratosphereOS from this repository: https://github.com/PatN-git/Stratosphere-OS
The agent follows the instructions below and does the rest. You'll be asked a couple of quick questions (install scope, and whether to install any missing dependency). Prefer to do it by hand? See Manual install.
