What it does
Database Design is an agent skill from xenitV1/Antigravity-Workflows. Database design principles and decision-making. Schema design, indexing strategy, ORM selection, serverless databases.
Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts (for example `database-selection.md`, `indexing.md` and `migrations.md`).
It sits in Databases, covering Database schema design and ORMs and data access. It works with PostgreSQL. The licence is MIT.
When your agent uses it
- Tasks that involve Database schema design
- Tasks that involve ORMs and data access
Example prompts
- “/database-design”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep
What it can do on your machine
Read from SKILL.md and the folder at commit f0a1fa7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
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
Database Design loads about 378 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 146 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); the scripts in this folder are not scanned.

Database Design
Learn to THINK, not copy SQL patterns.
🎯 Selective Reading Rule
Read ONLY files relevant to the request! Check the content map, find what you need.
| File | Description | When to Read |
|---|---|---|
database-selection.md | PostgreSQL vs Neon vs Turso vs SQLite | Choosing database |
orm-selection.md | Drizzle vs Prisma vs Kysely | Choosing ORM |
schema-design.md | Normalization, PKs, relationships | Designing schema |
indexing.md | Index types, composite indexes | Performance tuning |
optimization.md | N+1, EXPLAIN ANALYZE | Query optimization |
migrations.md | Safe migrations, serverless DBs | Schema changes |
⚠️ Core Principle
- ASK user for database preferences when unclear
- Choose database/ORM based on CONTEXT
- Don't default to PostgreSQL for everything
Decision Checklist
Before designing schema:
- Asked user about database preference?
- Chosen database for THIS context?
- Considered deployment environment?
- Planned index strategy?
- Defined relationship types?
Anti-Patterns
❌ Default to PostgreSQL for simple apps (SQLite may suffice) ❌ Skip indexing ❌ Use SELECT * in production ❌ Store JSON when structured data is better ❌ Ignore N+1 queries

Can I use Database Design in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add xenitV1/Antigravity-Workflows --skill database-design -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/database-design, .gemini/skills/database-design, .github/skills/database-design and .opencode/skills/database-design in your project.
What does Database Design need to run?
Going by SKILL.md and its folder, Database Design needs Python for the scripts in its folder. Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Edit, Glob, Grep.
Does Database Design access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Database Design safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Database Design use?
Database Design is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Database Design use?
About 378 tokens (SKILL.md is roughly 1.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
