What it does

Ksail is an agent skill from devantler-tech/ksail. Use the ksail CLI to spin up and manage Kubernetes clusters (Kind/K3d/Talos/vCluster/KWOK — local via Docker; EKS — cloud via AWS) and GitOps workloads declaratively. Triggers on requests involving Kubernetes clusters, Flux/ArgoCD GitOps bootstrapping, Kind/K3d/Talos/vCluster/KWOK/EKS, multi-tenancy onboarding, OIDC authentication, or the ksail CLI/MCP server.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Container orchestration, GitOps and Containers. It works with Kubernetes, Model Context Protocol, Docker and Amazon Web Services. The repository describes itself as: All-in-one Kubernetes SDK: create, manage, and operate clusters across distributions (Kind, K3d, Talos, VCluster) with built-in GitOps, secrets, AI assistant, and MCP server…

When your agent uses it

  • Requests involving Kubernetes clusters
  • Flux/ArgoCD GitOps bootstrapping
  • Kind/K3d/Talos/vCluster/KWOK/EKS
  • Multi-tenancy onboarding

Example prompts

  • “/ksail”

Requirements

  • Docker
  • A credential in HCLOUD_TOKEN
  • A credential in OMNI_SERVICE_ACCOUNT_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 3115397. 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

    Shell commands in SKILL.md call:

    • aws

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • ksail.devantler.tech

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • HCLOUD_TOKEN
    • OMNI_SERVICE_ACCOUNT_KEY
    • AWS_ACCESS_KEY_ID
    • AWS_SECRET_ACCESS_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ksail loads about 1.1k tokens when it runs. Until then it costs about 92 tokens; SKILL.md has 448 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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); files beside SKILL.md 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 448 words (~1,104 tokens).

“KSail bundles common Kubernetes tooling (kubectl, helm, kind, k3d, vcluster, flux, argocd, …) into a single Go binary. Local clusters need only Docker; cloud providers also need that provider's credentials, and EKS additionally needs the eksctl CLI.”
