What it does

Mg Railway DB Backup is an agent skill from modelguide/modelguide. Backup a PostgreSQL database from a Railway environment. Use when the user asks to "backup db", "dump database", "save db from railway", "backup railway database", or "export db".

Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases, covering Backup and disaster recovery. It works with PostgreSQL. The repository describes itself as: Open-source voice agent orchestration framework - build production voice AI pipelines without vendor lock-in. The licence is MIT.

When your agent uses it

  • The user asks to backup db
  • Save db from railway
  • Backup railway database

Example prompts

  • “backup db”
  • “dump database”
  • “save db from railway”
  • “/mg-railway-db-backup”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Link to the correct project and environment using Railway MCP link-environment tool
  2. Ensure output directory exists
  3. Run pg_dump — credentials piped from Railway CLI (never write credential values in commands)
  4. Verify the backup file exists and report path + size to the user.

What it can do on your machine

Read from SKILL.md and the folder at commit 554caa0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • railway
    • pg_dump

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mg Railway DB Backup loads about 534 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 150 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~534

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Backup a PostgreSQL database from a Railway environment. Use when the user asks to "backup db", "dump database", "save db from railway", "backup railway database", or "export db".

Railway DB Backup

Backup a PostgreSQL database from a Railway environment to a local file.

Inputs

Ask the user if not provided:

  • project — Railway project name
  • environment — Railway environment name to backup from (e.g., demo, production)

Procedure

  1. Link to the correct project and environment using Railway MCP link-environment tool:

    • workspacePath: <project-root>
    • environmentName: <environment>

  2. Ensure output directory exists:

    bash
    mkdir -p <project-root>/.claude/local

  3. Run pg_dump — credentials piped from Railway CLI (never write credential values in commands):

    bash
    VARS=$(railway variables -s Postgres -e <environment> --kv 2>/dev/null) && \
export PGPASSWORD=$(echo "$VARS" | grep '^PGPASSWORD=' | cut -d= -f2-) && \
PGUSER=$(echo "$VARS" | grep '^PGUSER=' | cut -d= -f2-) && \
PGDATABASE=$(echo "$VARS" | grep '^PGDATABASE=' | cut -d= -f2-) && \
DB_URL=$(echo "$VARS" | grep '^DATABASE_PUBLIC_URL=' | cut -d= -f2-) && \
PGHOST=$(echo "$DB_URL" | sed 's|postgresql://[^@]*@||;s|:.*||') && \
PGPORT=$(echo "$DB_URL" | sed 's|.*:||;s|/.*||') && \
pg_dump -h "$PGHOST" -p "$PGPORT" -U "$PGUSER" -d "$PGDATABASE" \
  --no-owner --no-acl -F c \
  | gzip > <project-root>/.claude/local/<project>-<environment>-backup-$(date +%Y%m%d-%H%M%S).dump.gz

    This reads credentials from railway variables into shell vars at runtime — no secrets ever appear in the command text.

  4. Verify the backup file exists and report path + size to the user.

Notes

  • Railway runs PostgreSQL 17 — if local pg_dump version is too old, use the one from postgresql@17 homebrew package
  • Backup format is custom (-F c) for efficient restore with pg_restore
  • --no-owner --no-acl strips ownership/permissions for portable restores
  • Backups are stored in .claude/local/ which is git-ignored
