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 | $0.00000 | $0.00102 |
| Opus 5 | $0.00000 | $0.00051 |
| Sonnet 5 | $0.00000 | $0.00020 |
| Haiku 4.5 | $0.00000 | $0.00010 |
Grade A, and why
server-patterns 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
Server Code Rules
- Follow the MVC pattern: routes define endpoints, controllers handle logic, services contain business logic.
- Use arrow functions. Never use the
classkeyword. - Middleware goes in
src/server/middleware/. - Configuration goes in
src/server/config/. - Use environment variables for secrets and configuration. Access them via
process.env. - Authentication uses Passport.js with LocalStrategy.
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.

server-patterns is a cursor rule published in the GitHub repository bishopZ/2026-Boilerplate (23 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 102 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
