Using Cursor with the Ankra CLI as an Infrastructure Subagent

Cursor is good at application code. It is much weaker once a change crosses the infrastructure boundary into Kubernetes manifests, Helm charts, and CI pipelines. The model has no live view of the cluster, so it falls back to generic snippets and guesses at namespaces, dependencies, and image tags.

Pointing Cursor at the Ankra CLI fixes that. The CLI gives Cursor a cluster-aware subagent that reads real state from your Ankra-managed clusters and proposes changes against the actual platform instead of free-floating YAML.

What the daily friction looks like today

How the Cursor + Ankra setup works

Cursor's LLM is strong on syntax and local application logic but has no live infrastructure data. The Ankra CLI fills that gap. It talks to Ankra's API, knows your clusters, stacks, addons, and manifests, and produces changes in the same shape Ankra-managed GitOps already uses.

Ankra also publishes an LLM-friendly documentation index at https://docs.ankra.ai/llms.txt. Adding it as a doc source in Cursor grounds prompts in the real CLI surface instead of hallucinated kubectl snippets.

Wire it up once:

1. In Cursor, open Settings, Features, Docs, Add new doc.
2. Paste https://docs.ankra.ai/llms.txt and name it Ankra.
3. Prompt with @Docs Ankra (or just @Ankra) when you want infrastructure context.

From that point on, infrastructure prompts produce Ankra CLI invocations and Ankra-managed Stack edits instead of one-off manifests.

Use cases

1. Self-service onboarding

Onboarding a new engineer often means a stale README, environment variables to chase down, cryptic shell scripts, and a hope that the local Kubernetes setup matches staging.

Instead, a new developer clones the repo in Cursor, opens the integrated terminal, and runs:

1ankra login
2ankra cluster select development-sandbox
3ankra chat "Spin up the microservice dependency mesh for the payment gateway"

The subagent reads the cluster state, checks namespace capacity, configures local connections, and gets the developer to a working environment in hours instead of weeks.

2. Draft-first GitOps

Platform teams hesitate to give developers (or their AI tools) write access to clusters, because automated execution can wipe databases or break ingress.

Ankra runs a draft-first, GitOps-backed model. When the subagent modifies infrastructure from the Cursor terminal, it does not touch live clusters directly. It produces an isolated Draft inside Ankra. Once approved, Ankra's engine syncs the draft back to your GitHub or GitLab repository. Git stays the source of truth, and platform teams review the AI-generated change like any other pull request.

3. Incident triage in the IDE

A local or staging deployment crashes. The usual loop is the developer wading through Kube-API streams while operations is dragged into a call to run root cause analysis.

Ankra is wired to both Prometheus metrics and live Kube-API state, so the developer can diagnose the failure from Cursor without context switching:

1ankra chat "Why are my payment-service pods crashing in the dev-sandbox cluster?"

The subagent cross-references container logs, resource limits, and cluster events and returns something like "The pod is OOMKilled because the memory limit is set to 256Mi while Redis initialization requires 512Mi. Here is a draft Stack edit to raise the limit." The fix arrives as a draft for review, not as a kubectl edit that mutates the cluster behind your back.

4. Environment cloning for QA and demos

Replicating a production issue usually means replicating production-grade infrastructure, which is too expensive, complex, or insecure to do on demand.

Ankra clones existing Stacks, with their dependency graph and Helm values intact, into any target cluster (local OrbStack, a sandbox, or a QA cluster). The CLI operates on the ImportCluster definitions you already version in Git:

1# Clone the analytics-engine stack from prod into a local cluster file
2ankra cluster clone prod.cluster.yaml local.cluster.yaml \
3  --stack "analytics-engine"
4
5# Apply the resulting cluster definition to the active local cluster
6ankra apply local.cluster.yaml

Variables resolve per environment, dependencies are re-mapped, and production secrets are not propagated. The developer gets a ring-fenced replica on their laptop or sandbox to exercise edge cases before they reach staging.

What changes for the rest of the org

Adopting this setup is not only about typing less YAML.

• Product managers see features move from ideation to deployment faster because the infrastructure bottleneck shrinks.
• Platform engineers spend less time as ticket handlers and more time optimizing base stacks and defining the policies that every Ankra-managed change must satisfy.
• Security and compliance teams get a consistent audit trail. Every infrastructure change, including AI-generated ones, goes through GitOps review, version control, and SOPS-encrypted secrets. No raw cloud credentials in the agent, no out-of-band kubectl edits.

Cursor handles the application code. The Ankra CLI subagent handles the infrastructure, with drafts and GitOps reviews in between. Developers move quickly and operations keeps the guarantees they need.
