It sits in Databases, covering Database migrations. The repository describes itself as: Connect your agents & product to 1,000 APIs.
When your agent uses it
- Editing Nango database migrations - covers migration directory selection
- Timestamped .cjs naming
- Matching recent migration style
- Down migration decisions
Example prompts
- “/creating-database-migrations”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify the right migration directory.
- Before writing a migration, read 2-3 recent migrations in the same directory and follow their style.
- Name new main database migrations with the timestamped CommonJS format
- Decide exports.down explicitly.
- Choose foreign key delete behavior from the relationship
What it can do on your machine
Read from SKILL.md and the folder at commit 8a86a48. 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.
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
Creating Database Migrations loads about 449 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 183 words of instructions outside code blocks.
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 183 words (~449 tokens).
