polar-local-environment
This skill should be used when setting up or managing Polar local development environment with Docker.
npx skills add fcakyon/claude-codex-settings --skill polar-local-environment --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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. Priority: 1. `POLAR_DOCKER_INSTANCE` pinned in `dev/docker/.env.do

What does the polar-local-environment skill do?
This skill should be used when setting up or managing Polar local development environment with Docker.
How do I install it?
Run `npx skills add fcakyon/claude-codex-settings --skill polar-local-environment --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From fcakyon/claude-codex-settings, a repository with 967 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
