antigravity-project-starter: Skill for Claude Code

.agent/skills/architecture-database-design/SKILL.md

architecture-database-design is a skill for Claude Code, Codex from Sn4kyGit/antigravity-project-starter. It costs 42 tokens per session (659 once invoked), scanned A, original, no licence file.

A guide for designing PostgreSQL databases, improving query performance, and making safe database changes.

In plain words
What is it for?
It is for modifying database tables, IDs, indexes, JSONB fields, and migrations that change the database structure.
Why use it?
It helps prevent inconsistent schemas, slow data access, and risky changes to stored data.

Skill for Claude CodeCodex

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing.

This is Sn4kyGit/antigravity-project-starter's own configuration. It tells Claude Code and Codex how to work on antigravity-project-starter itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything antigravity-project-starter configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

architecture-database-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
