Databasement is a self-hosted web application for scheduling, storing, and restoring backups of several kinds of databases. It is for managing database backups across local storage, S3-compatible storage, SFTP, Samba, and other configured destinations, including databases in private networks. The catalogue instruction and MCP integration connect coding agents to its backup-management workflows.
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 5.1 | $0.10841 | $0.10841 |
| Opus 5 | $0.05421 | $0.05421 |
| Sonnet 5 | $0.02168 | $0.02168 |
| Haiku 4.5 | $0.01084 | $0.01084 |
Grade A, and why
databasement CLAUDE.md 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 613 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
This is a Laravel application for managing database server backups. It uses Livewire for reactive components and Mary UI (robsontenorio/mary, built on daisyUI and Tailwind CSS). The application allows users to register database servers (MySQL, PostgreSQL, MariaDB, SQLite, Redis/Valkey), test connections, and manage backup configurations. See Boost's Foundational Context below for exact package versions.
Development Commands
IMPORTANT: All PHP commands MUST be run through Docker. Never run php, composer, or vendor/bin/* commands directly on the host. Use the Makefile targets or docker compose exec --user application -T app <command> instead. Always include --user application to ensure correct file permissions.
This overrides any bundled guideline or skill that shows a bare command — notably the pestphp/pest-plugin-agent rules at the end of this file, whose vendor/bin/pest --agent='…' examples must be run as docker compose exec --user application -T app vendor/bin/pest --agent='…'.
Setup and Installation
make setup # Full project setup: install deps, env setup, generate key, migrate, build assets
make install # Install composer and npm dependencies only
docker compose exec --user application -T app composer require <package> # Install a composer package
docker compose exec --user application -T app composer remove <package> # Remove a composer package
Running the Application
make start # Start all Docker services: php (FrankenPHP), queue worker, mysql, postgres, redis
docker compose up -d # Alternative: direct docker compose command
docker compose logs -f # View logs from all services
docker compose logs -f queue # View queue worker logs only
Testing
IMPORTANT: ALWAYS use make test commands for running tests. NEVER use docker compose exec ... php artisan test directly - it runs tests sequentially and is much slower.
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.

databasement CLAUDE.md is an instructions file published in the GitHub repository David-Crty/databasement (2,327 stars, last pushed today), licensed MIT. It adds 10,841 tokens to every session, about $0.0542 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.
