What it is

8 Cursor project rules (.mdc) for Supabase, scoped so each loads only when relevant, with an installer that detects your stack, an AGENTS.md exporter (Claude Code, Codex) and a rules linter. Written against current docs (checked Nov 2026; Supabase publishable/secret keys, @supabase/ssr).

What you get

The screenshot is real output from the kit’s own commands. Tested from a fresh download of this exact zip: ./run_tests.sh ran 8 tests OK on Python 3.13 and 3.10.

Install in 30 seconds

python3 tools/install_rules.py --detect /path/to/app          # what it finds
python3 tools/install_rules.py /path/to/app --auto            # install rules for detected stacks into .cursor/rules/
python3 tools/install_rules.py /path/to/app --all --agents-md # everything, plus AGENTS.md
python3 tools/lint_rules.py /path/to/app/.cursor/rules --project /path/to/app

Existing files are never overwritten unless you pass --force; --dry-run previews. ./tools/demo.sh runs it on examples/sample-app; ./run_tests.sh runs the tests. As a Cursor plugin, the manifest is .cursor-plugin/plugin.json.

Honest limits

Rules guide the model; they don't enforce anything. Check version-specific advice against the versions in your lockfile (each overview rule tells the agent to do this).
Detection is file-based (package.json, manage.py/requirements, Gemfile, supabase/); in monorepos run it per package or use --stack.
