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 | $0.00024 | $0.00451 |
| Opus 5 | $0.00012 | $0.00226 |
| Sonnet 5 | $0.00005 | $0.00090 |
| Haiku 4.5 | $0.00002 | $0.00045 |
Grade A, and why
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 yesterday.
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
Manage PostgreSQL, SQLite, and Redis databases: create, migrate, backup, restore, query, optimize.
When to Use
- Setting up new databases or tables
- Running schema migrations
- Creating and restoring backups
- Debugging query performance
- Managing database users and permissions
- Health checking database instances
Scripts
| Script | Purpose | Usage |
|---|---|---|
backup.sh |
Backup/restore PostgreSQL or SQLite databases | bash scripts/backup.sh backup|restore <type> <db> [file] |
migrate.sh |
Run SQL migration files in order | bash scripts/migrate.sh <db-url> <migrations-dir> |
health-check.sh |
Check database connectivity and basic stats | bash scripts/health-check.sh <type> <connection> |
user-manager.sh |
Manage PostgreSQL users and permissions | bash scripts/user-manager.sh create|grant|revoke|list <args> |

Examples
Backup a SQLite database

Run migrations
bash scripts/migrate.sh sqlite:///path/to/db.sqlite3 ./migrations/
Health check PostgreSQL
bash scripts/health-check.sh postgres "host=localhost dbname=myapp user=admin"
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.

database is a skill published in the GitHub repository JansenAnalytics/claudex (5 stars, last pushed 2mo ago), licensed MIT. It adds 24 tokens to every session and 451 once invoked, about $0.0001 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 2026-08-31.
