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 | $0.00144 |
| Opus 5 | $0.00000 | $0.00072 |
| Sonnet 5 | $0.00000 | $0.00029 |
| Haiku 4.5 | $0.00000 | $0.00014 |
Grade A, and why
go 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
The fundamental rules to implement Go code
Best Practices
- Always run
go buildafter making changes - Use
gofmtfor code formatting - Write unit tests for new features
- Use interfaces for better abstraction
- Keep functions small and focused
Reminders
- After change: Don't forget to run
go buildto verify your changes - Before commit: Run all tests and linters before committing
Code comment
- Always describe in English
Linting
- golint
- staticcheck
- errcheck
Formatting
- gofmt
- goimports
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.

go is a cursor rule published in the GitHub repository ubie-oss/mcp-proxy (11 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 144 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 2026-08-31.
