The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai).

Test report

Verdict: Works with setup
Score: 7.2/10
Tested: Jul 24, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · 0d4b0b5

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 24, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

The 39 bundled skills are genuinely detailed reference docs (the schema-design skill maps every column type to its Postgres type and the manage_schema DSL actions), but every skill's real payload is Butterbase's hosted MCP tools, which need a Butterbase account and per-client OAuth to api.butterbase.ai — so the actual value is unmeasurable behind that login wall. Note the plugin also auto-configures an MCP pointing at a third-party endpoint on install.

What Butterbase Skills does

Bundles guided skills for schema design, auth, serverless functions, RLS debugging, RAG, realtime, payments and deploy on the Butterbase platform, and auto-wires an MCP server at api.butterbase.ai. Triggers when you ask to build, design, deploy or debug a Butterbase-backed app.

How to install Butterbase Skills

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
