db-transaction-handling

db-transaction-handling is a skill for Claude Code, Codex from blunotech-dev/agents. It costs 49 tokens per session (2,379 once invoked), scanned A, original, no licence file.

A guide for handling database transactions correctly. A transaction groups database changes so they can be completed together or rolled back if something fails.

In plain words
What is it for?
It is for choosing isolation levels, adding retries, rolling back failures, and using database locks such as SELECT FOR UPDATE.
Why use it?
It helps prevent conflicting updates, deadlocks, and inconsistent data when multiple operations run at the same time.

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

db-transaction-handling scanned grade A with 1 finding 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 4d 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.

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.
