What it does

DB Migration Scripts is an agent skill from golemcloud/golem. Writing database migration SQL scripts. Use when creating or modifying migration files under db/migration/ directories, adding tables, indexes, or columns.

Its SKILL.md is about 1.5k 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 Database migrations. It works with SQL, PostgreSQL and SQLite. The repository describes itself as: Golem Cloud is the agent-native platform for building AI agents and distributed applications that never lose state, never duplicate work, and never require you to build…

When your agent uses it

  • Modifying migration files under db/migration/ directories
  • Tasks that involve Database migrations

Example prompts

  • “/db-migration-scripts”

Workflow steps

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

  1. Confirm that the PostgreSQL and SQLite filenames and schema results match.
  2. Run an affected persistence/repository test against both database variants. The selected test
  3. Run the smallest affected crate check and tests with --report-time.

What it can do on your machine

Read from SKILL.md and the folder at commit 2dea6b9. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are sql).

    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

DB Migration Scripts loads about 1.5k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 675 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 675 words (~1,491 tokens).
