A skill for protecting SQLite databases by continuously copying their changes to cloud or remote storage. SQLite is a database stored in a single file, and Litestream is the tool used for this copying and recovery.

Use it to configure Litestream, replicate SQLite changes to S3, Google Cloud Storage, Azure, SFTP, NATS, or files, troubleshoot replication, and restore earlier database states.

It reduces the risk of losing database data and supports recovery when the original file is damaged or unavailable.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.01393
Opus 5	$0.00030	$0.00696
Sonnet 5	$0.00012	$0.00279
Haiku 4.5	$0.00006	$0.00139

Security

Grade B, and why

litestream scanned grade B with 2 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/check-replication.sh, scripts/diagnose-issues.sh, scripts/validate-config.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

A mod that escalates privileges can change anything on the machine, not only the project.

Litestream

Litestream is a disaster recovery tool for SQLite that runs as a background process, continuously replicating database changes to cloud storage. It monitors the SQLite Write-Ahead Log (WAL), converts changes to immutable LTX files, and uploads them to your chosen storage backend.

Key Concepts

WAL Monitoring: Watches SQLite Write-Ahead Log for changes at configurable intervals (default 1s)
LTX Files: Immutable files containing database page changes, never modified after creation
Level-Based Compaction: Multi-level system (L0-L9) that merges LTX files to reduce storage overhead
Point-in-Time Recovery: Restore to any transaction using TXID or timestamp
VFS Support: Read replicas directly from cloud storage without local database copy
MCP Server: AI tool integration for automated database management

Quick Start

Installation

# macOS
brew install litestream

# Linux (Debian/Ubuntu)
wget https://github.com/benbjohnson/litestream/releases/download/v0.5.5/litestream-v0.5.5-linux-amd64.deb
sudo dpkg -i litestream-v0.5.5-linux-amd64.deb

# Docker
docker pull litestream/litestream:0.5

Basic Replication

# Command line (single database)
litestream replicate /path/to/db.sqlite s3://bucket/db

# With config file
litestream replicate -config /etc/litestream.yml

Restore Database

# Restore latest backup
litestream restore -o /path/to/restored.db s3://bucket/db

# Point-in-time recovery
litestream restore -timestamp 2024-01-15T10:30:00Z -o /tmp/db s3://bucket/db

# Restore to specific transaction
litestream restore -txid 1000 -o /tmp/db s3://bucket/db

Check Status

# View all databases and their replication status
litestream status

# List available LTX files
litestream ltx /path/to/db.sqlite

Critical Rules

These rules are essential for correct Litestream operation:

Lock Page at 1GB: SQLite reserves the page at offset 0x40000000 (1GB). This page must always be skipped during replication and compaction. The page number varies by page size:
- 4KB pages: page 262145
- 8KB pages: page 131073
- 16KB pages: page 65537

Files

What ships with it

33 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.

Changes

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.

litestream is a skill published in the GitHub repository benbjohnson/litestream-skills (5 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 59 tokens to every session and 1,393 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
