This skill should be used when setting up or managing Polar local development environment with Docker.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Local Environment Skill Helps manage the Polar local development environment through the `dev docker` CLI. Use it to start, stop, debug, or reason about the local stack. ## The two-part model `dev docker` deliberately splits the stack so many worktrees can share one set of heavy infra: - **Shared infra** — one copy per machine, Docker project `polar-shared`: postgres, redis, minio, tinybird, and optional prometheus/grafana. Postgres and redis publish no host ports; MinIO exposes 9000/9001 for browser uploads. Use `dev docker exec <service> ...` for services without host ports. - **Per-instance app stack** — one per worktree, project `polar-app-<N>`: api, worker, web. Only **api and web** publish host ports, offset per instance so worktrees don't collide. Knowing this prevents the most common confusion: there is no `localhost:5432` for the database (it lives in the shared stack and is reached through `dev docker exec db ...`). MinIO does expose ports 9000/9001 for browser uploads and console access. ## Instance auto-detection `dev docker` auto-detects the instance for the current worktree, so `-i` is rarely needed.

How to install
mdr add fcakyon/claude-codex-settings/polar-local-environment@sha256:6e40a7e5de35d54aThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
