Manages the Traefik-based Kubernetes Gateway API extension in KubeSphere: install, uninstall, status checks, GatewayProxy inspection and troubleshooting.
- Works in 3 steps: Detect and Select Version → Detect and Select Clusters → Generate and Apply InstallPlan
- Installing the Traefik-based Gateway API extension in KubeSphere
- SKILL.md covers Overview, Before You Start, Installation and Status Checking, plus 3 more sections
- Runs Shell scripts from its folder; calls kubectl and helm
What it does
This skill manages external access in KubeSphere through the Kubernetes Gateway API, with Traefik as the proxy. It is the newer of two gateway skills; the older ingress-nginx based one, with its own Gateway CRD, belongs to the separate `kubesphere-gateway` skill, and the text includes a side-by-side table of proxy, API standard, core resources and lifecycle management.
GatewayProxy resources come in three tiers, cluster, workspace and project, each with its own name pattern in the `kubesphere-controls-system` namespace. Each GatewayProxy deploys a Traefik instance and creates a GatewayClass automatically, and users then create standard Gateway resources that point at that class. The extension has three components: a backend extension API server on the host cluster, a backend agent on every cluster and a React front end served through Nginx.
Covered tasks are installation, uninstallation, status checks, GatewayProxy status inspection and troubleshooting, supported by three shell scripts: `check-status.sh`, `generate-installplan.sh` and `verify-uninstall.sh`.
When your agent uses it
- Installing the Traefik-based Gateway API extension in KubeSphere
- Inspecting the status of a GatewayProxy at cluster, workspace or project level
- Choosing between the Gateway API extension and the older ingress-nginx gateway
- Verifying that an uninstall removed all gateway resources
Example prompts
- “Install the KubeSphere Gateway API extension and check its status when it finishes.”
- “Show me the status of the workspace-level GatewayProxy for team-a.”
- “Should I use kubesphere-gateway or kubesphere-gateway-api on a new cluster?”
- “Confirm that the Gateway API extension was fully uninstalled.”
Requirements
- A running KubeSphere cluster
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Detect and Select Version
- Detect and Select Clusters
- Generate and Apply InstallPlan
What it can do on your machine
Read from SKILL.md and the folder at commit 04a29b5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
kubectlhelm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use kubectl and helm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
KubeSphere Gateway API Extension loads about 3.7k tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 764 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 764 words (~3,740 tokens).
“Provides external access management using Kubernetes Gateway API with Traefik as the underlying proxy implementation. Supports three-tier gatewayproxy management:”
