Casbin Gateway is a local gateway that lets coding agents on a computer use different AI model providers through one endpoint. It runs on the user's machine and provides a local web interface for managing access to those agents and models.

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 | $0.00134 | $0.00134 |
| Opus 5.5 | $0.00054 | $0.00054 |
| Sonnet 5.5 | $0.00027 | $0.00027 |
| Haiku 4.5 | $0.00013 | $0.00013 |
Grade B, and why
casbin-gateway CLAUDE.md scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- Never put a space between Chinese and Latin letters, digits, or placeholders. Write `每个Agent`, `覆盖{count}个`, `写在~/.codex/config.toml里` — not `每个 Agent`. What it actually says
CLAUDE.md
Code style
- Don't add Go tests unless asked. Verify changes by building or running the code instead.
- Keep comments sparse and short. No paragraph-length doc blocks, no narration of what the code obviously does.
Chinese translations
- Never put a space between Chinese and Latin letters, digits, or placeholders. Write
每个Agent,覆盖{count}个,写在~/.codex/config.toml里— not每个 Agent. - "Agent" stays English in Chinese text. The product term is
Agent客户端; a spawned sub-agent is子Agent. Never智能体.
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.

casbin-gateway CLAUDE.md is an instructions file published in the GitHub repository apache/casbin-gateway (643 stars, last pushed 5d ago), licensed Apache-2.0. It adds 134 tokens to every session, about $0.0005 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
