Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00072 | $0.00670 |
| Opus 5 | $0.00036 | $0.00335 |
| Sonnet 5 | $0.00014 | $0.00134 |
| Haiku 4.5 | $0.00007 | $0.00067 |
Grade A, and why
tsq-database 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 5d 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 it actually says
Database Methodology
Resources
| Priority | Type | Resource | Description |
|---|---|---|---|
| HIGH | rule | supabase-patterns | JSONB, RLS, Edge Runtime, USE_MOCK, 커넥션 풀링 |
정규화 기준
| 정규형 | 적용 기준 | 예외 허용 조건 |
|---|---|---|
| 1NF | 필수 | 없음 |
| 2NF | 필수 | 없음 |
| 3NF | 기본 적용 | 읽기 성능 요구 시 |
| BCNF | 권장 | 복잡도 증가 시 |
비정규화 조건
비정규화 결정 시 반드시 ADR 작성:
## ADR-XXX: [테이블명] 비정규화 결정
### Context
- 읽기 빈도: X회/초, 쓰기 빈도: Y회/초, 조인 비용: Z ms
### Decision
[비정규화 결정 내용]
### Consequences
- 장점: 읽기 성능 N% 향상
- 단점: 데이터 중복, 갱신 이상 위험
- 대응: [트리거/애플리케이션 로직]

마이그레이션 규칙
파일 명명
{timestamp}_{description}.sql
예: 20260203100000_create_users_table.sql
안전한 마이그레이션
| 작업 | 안전 | 위험 | 대안 |
|---|---|---|---|
| 컬럼 추가 (NULL) | O | ||
| 컬럼 추가 (NOT NULL) | ! | DEFAULT 값 + NULL 허용 후 변경 | |
| 컬럼 삭제 | ! | 코드 먼저 수정 -> 삭제 | |
| 컬럼명 변경 | X | 새 컬럼 추가 -> 데이터 이동 -> 삭제 | |
| 인덱스 추가 | O | CONCURRENTLY 사용 | |
| 테이블 삭제 | X | 백업 확인 필수 |
롤백 전략
모든 마이그레이션에 롤백 스크립트 필수:
-- Up
ALTER TABLE users ADD COLUMN phone VARCHAR(20);
-- Down
ALTER TABLE users DROP COLUMN phone;

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

tsq-database is a skill published in the GitHub repository sonature-lab/timsquad (11 stars, last pushed 5d ago), licensed MIT. It adds 72 tokens to every session and 670 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
