postgres-adopt skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.
postgres-adopt is agent-read markdown (skill) from garrytan/gbrain: Detect which gbrain engine is in use (PGLite vs Postgres), prefer Postgres for agent-harness installs, install/provision Postgres (Supabase discovery via SUPABASE_ACCESS_TOKEN, local Postgres, opt-in Docker), and move an existing PGLite brain with the guarded engine migration. Detection is one engine-free command; the install ladder is one flag..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Postgres Adopt > The engine is the brain's foundation: PGLite is the zero-config floor, > Postgres is where concurrency, multi-machine access, and 1000+ pages live. > This skill answers "which one am I on?", prefers Postgres when the > operator wants it, and moves data safely — never by flipping config. ## Contract This skill guarantees: - Detection is engine-free and read-only: `gbrain engine status --json` answers with the database down (that is the point of the command). - Engine changes NEVER happen by editing config. Moving data uses `gbrain migrate --to <supabase|pglite>` — which brings its own guardrails (quiesce mutex, resume manifest, non-empty-target guard, and a config flip only on a fully clean run). This skill wraps it; it never reimplements it. - Provisioning consent is explicit: the docker rung needs `--allow-docker`, creating a database on a local server needs `--allow-create-db`. Headless mutation of infrastructure the operator didn't opt into never happens. ## Step 1 — Detect ```bash gbrain engine status --json ``` Branch on the output: - `effective_engine: "postgres"` and (optionally) `--probe` says ok → report healthy, done. …

How to install
mdr add garrytan/gbrain/postgres-adopt@git:20260827.534a27amdr add garrytan/gbrain/postgres-adopt@sha256:4c402527bd0d98aaPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
