multiline-commit-messages

multiline-commit-messages is a skill for Claude Code, Codex from prisma/orm. It costs 35 tokens per session (281 once invoked), scanned A, original, Apache-2.0.

A shell-use rule for writing Git commit messages that contain multiple lines. It recommends single-quoted strings with literal newlines instead of fragile heredoc commands.

In plain words
What is it for?
It helps developers create readable multi-line Git commit messages safely from the command line.
Why use it?
It prevents shell quoting problems that can turn a carefully written commit message into broken or literal command text.

About the project

Prisma ORM is a Node.js and TypeScript database toolkit that lets applications work with databases through a programming interface instead of writing every query directly in SQL. Developers use it with databases including PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB, and CockroachDB. The catalogue add-ons provide agent rules, skills, hooks, agents, and other workflows for using Prisma.

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

multiline-commit-messages 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 2d 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

Multiline commit messages

The Shell tool sends commands as a single string. Heredoc syntax (<<'EOF') inside $(cat ...) is fragile and fails silently — the literal $(cat <<'EOF' ... ends up as the commit message instead of the intended text.

Rule

Never use $(cat <<'EOF' ...) or $(cat <<EOF ...) for commit messages.

Use single-quoted strings with embedded newlines:

git commit -m 'short summary line

Longer body paragraph explaining why the change exists.
Additional context if needed.'

Why heredocs fail

The Shell tool passes the command as a single string argument. When you write:

git commit -m "$(cat <<'EOF'
message
EOF
)"

The shell may not parse the heredoc correctly in this context — the EOF delimiter, newlines, and nested quoting interact unpredictably. The result is the raw $(cat <<'EOF' ... text appearing as the commit message.

Single-quoted strings with literal newlines are simple, portable, and always work.

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.
