It checks application roles alongside `pg_strict` settings. The audit also covers Traffic Control rules and PITR backup policies. The agent operates strictly in an advisory mode. It does not alter credentials or run migrations on its own. The review inspects connection routing between direct port 5432 and PgBouncer port 6432. For session diagnostics, it references `pscale branch connections top`. It flags applications connecting via default database roles and highlights Terraform state security with `planetscale_postgres_redacted_branch_role`. Enforcing `pg_strict` carries immediate operational risk, because unindexed `UPDATE` or `DELETE` statements lacking a `WHERE` clause will get blocked after new connections establish. ## Requirements - Works with: PostgreSQL ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add planetscale/skills --skill planetscale-postgres-safety-review -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/planetscale-postgres-safety-review/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/planetscale-postgres-safety-review/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add planetscale/skills --skill planetscale-postgres-safety-review -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/planetscale-postgres-safety-review/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add planetscale/skills --skill planetscale-postgres-safety-review -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/planetscale-postgres-safety-review/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install planetscale/skills planetscale-postgres-safety-review ``` 2. **Manually: put the files in place** - File: `.github/skills/planetscale-postgres-safety-review/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add planetscale/skills --skill planetscale-postgres-safety-review -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/planetscale/skills --path planetscale-postgres-safety-review ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/planetscale-postgres-safety-review/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add planetscale/skills --skill planetscale-postgres-safety-review -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/planetscale/skills/tree/HEAD/planetscale-postgres-safety-review/SKILL.md ## When to use it - audit Postgres roles and least-privilege access rules - evaluate pg_strict rollout readiness to prevent accidental table wipes - standardize SQLCommenter query tags for Traffic Control and Insights - verify backup retention schedules and PITR recovery runbooks ## Example prompts - Run a safety review on our PlanetScale Postgres database - Check if our application is ready for pg_strict and Traffic Control - Audit database roles and backup retention policies in PlanetScale Postgres ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 94e82f6d19f735ad ```text --- name: planetscale-postgres-safety-review description: Review PlanetScale Postgres for Traffic Control, query tags, roles, pg_strict, backups/PITR, private connectivity, webhooks, branches, and safe agent operation. --- # Postgres safety review ## Purpose Recommend best practices for a PlanetScale Postgres database. Focus on availability protection, application isolation, recovery, safe automation, and observability. Do not apply changes. ## Branch and schema workflow PlanetScale Postgres branches do not use Vitess-style deploy requests. Schema changes are made directly to each branch, and production schema changes should be managed through the application’s normal migration workflow with a branch validation step. Check: - Whether a development or test branch exists. - Whether branches are empty or restored from backup. - Whether migrations are tested against a branch before production. - Whether application migrations are reversible or have a documented rollback strategy. - Whether production DDL is manually reviewed. Recommend: - Create or use a non-production branch for migration testing. - Run migration validation and application tests against that branch. - Treat production migration application as an explicit human-approved deployment step. - Use PITR/backup restore branches for incident recovery, not as an automatic rollback mechanism. Do not create branches, run migrations, or restore backups without approval. ## Roles and least privilege Check whether the application connects with the default role. Flag this as a safety gap. Recommend: - Use user-defined application roles, not the default role, for application servers. - Separate roles by service, environment, and access pattern. - Use read-only roles for analytics, dashboards, reporting, and agents that do not need writes. - Use short-lived or purpose-limited roles for automation. - When Terraform manages PlanetScale Postgres roles, prefer `planetscale_postgres_redacted_branch_role` for roles whose password should stay out of Terraform state; reset the password through the API or dashboard and store it in the team's secret manager. - Document credential rotation without application downtime. Do not create, reset, delete, or rotate roles without approval. ## pg_strict Check whether pg_strict is enabled for application roles. Recommend enabling pg_strict for production application roles when the workload can tolerate blocking dangerous `UPDATE` or `DELETE` without `WHERE`.
