Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

What 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 5.1 | $0.00183 | $0.06373 |
| Opus 5.5 | $0.00073 | $0.02549 |
| Sonnet 5.5 | $0.00037 | $0.01275 |
| Haiku 4.5 | $0.00018 | $0.00637 |
Grade A, and why
huawei-cloud-devbridge-tunnel scanned grade A 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 15d 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.

Huawei Cloud DevBridge Development Tunnel
Create and manage DevBridge development tunnels to securely expose local development services to remote devices via Huawei Cloud relay infrastructure.
Overview
DevBridge is a development tunnel service that allows developers to expose local services (web servers, APIs, debug endpoints) to remote devices without opening public inbound ports. The CLI tool (devbridge) manages tunnels, ports, host connections, and connect sessions. Host and Connect both initiate outbound connections to the relay service, so the hosting device does not need a public inbound port.

2026-09-20 域名升级通知：DevBridge 隧道域名已切换，原
*.cn-north-4-bridge.myhuaweicloud.com变更为新集群域名（如*.devbridge-s2.hwtunnel.com）。旧版端侧（v0.1.x）已无法连接，必须使用 v0.2.x 并重新创建隧道。以devbridge host实际输出的 Tunnel URL 为准。
Use Cases
- Remote debugging and integration testing with team members
- Sharing in-development web pages with stakeholders
- Receiving webhook callbacks during local development
- Accessing local services from mobile devices or other machines
- Temporarily exposing local APIs for demonstrations

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.

huawei-cloud-devbridge-tunnel is a skill published in the GitHub repository huaweicloud/huaweicloud-skills (59 stars, last pushed yesterday), licensed MIT. It adds 183 tokens to every session and 6,373 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
