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 | $0.00035 | $0.00281 |
| Opus 5.5 | $0.00014 | $0.00112 |
| Sonnet 5.5 | $0.00007 | $0.00056 |
| Haiku 4.5 | $0.00003 | $0.00028 |
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 1mo 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.
This is a copy
100% identical to multiline-commit-messages — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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.
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.

multiline-commit-messages is a skill published in the GitHub repository prisma/prisma-next (414 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 35 tokens to every session and 281 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to multiline-commit-messages, differing in 0 lines, and is treated as a copy.
