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.
npx agentmods add rules/prisma/prisma-next/mermaid-compatgit clone --depth 1 https://github.com/prisma/prisma-nextWhat 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 | $0.00000 | $0.00124 |
| Opus 5 | $0.00000 | $0.00062 |
| Sonnet 5 | $0.00000 | $0.00025 |
| Haiku 4.5 | $0.00000 | $0.00012 |
Grade A, and why
mermaid-compat 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 3d 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 mermaid-compat — 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
Mermaid compatibility (docs)
Different Mermaid renderers (GitHub, VS Code previews, docs sites) can be stricter than Mermaid itself. To avoid parse/render failures in project docs:
- Prefer ASCII in node labels (avoid curly quotes, arrows like
→, ellipses like…, and emoji prefixes). - Avoid Markdown formatting inside labels (especially backticks).
- Prefer
direction TBinsidesubgraphblocks. - Keep labels short; move detail to surrounding Markdown.
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.

mermaid-compat is a cursor rule published in the GitHub repository prisma/prisma-next (420 stars, last pushed 8d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 124 tokens. A static security scan graded it A with 0 findings. It is 100% identical to mermaid-compat, differing in 0 lines, and is treated as a copy.
