What's new

**2026-09-29: Current models and the development process.** Agents and configs now pin the current lineup: `claude-opus-5-5` (default), `claude-sonnet-5-5` and `claude-haiku-4-5`, with `claude-fable-5-1` named for the hardest work. The Opus 4.7 docs stay as history. A new [Development process](#development-process) section points to the development-protocol repo, and `toolkit/install.sh` can install it as an optional step. Full list in [CHANGELOG.md](CHANGELOG.md).

**2026-04-16 — Opus 4.7 alignment.** The env is now aligned to Claude Opus 4.7 (released 2026-04-16). CARL ships a new always-on `opus-4-7` domain encoding the 7 behavior rules; agents are pinned to explicit model IDs (`claude-opus-4-7` / `claude-sonnet-4-6` / `claude-haiku-4-5`); a single `opus-4-7-operating-notes.md` file is the source of truth, referenced from global + per-project CLAUDE.md. The focused migration kit — docs, templates, runnable examples, Instagram carousel source — lives in a companion repo for shareability: **[opus-4-7-playbook](https://github.com/7alexhale5-rgb/opus-4-7-playbook)**.

What is this?

Gravity Stack documents a production AI-native development environment built on Claude Code. The current snapshot:

35+ plugins across official and custom marketplaces (installed, pinned, categorized)
10+ MCP servers — browser automation, web scraping, search, memory, knowledge bases
20 lifecycle hooks — CARL injection, 4D senses, commit gates, closeout guards, media auto-vision, design-decision capture
78 first-class skills + ~100 plugin-provided skills across 14 categories. Full catalog: `toolkit/env/skills-catalog.md`
CARL engine — a ~1,700-line Python governance engine with context brackets, 6 domain rules, and the planning router
9 specialized agents ac
