What is gitops-knowledge?

Reference guidance for Flux CD, a tool that keeps Kubernetes applications matched to configuration stored in Git or another source.

Answering questions and creating YAML files for Flux resources such as Helm releases, repositories, and deployment configurations.

It helps explain Flux concepts and produce configuration with the correct resource names and fields.

gitops-knowledge — Skill for Claude Code by fluxcd/agent-skills

Install

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.

Clone the repo

git clone --depth 1 https://github.com/fluxcd/agent-skills

agentmods

npx agentmods add skills/fluxcd/agent-skills/gitops-knowledge

Made for: Claude Code.

Or install gitops-skills, the plugin that ships this one along with the rest of its 3 skills.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Privilege Escalation · line 119
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

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	$0.00128	$0.03811
Opus 5.5	$0.00051	$0.01524

Security

Grade A, and why

gitops-knowledge scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Flux CD Knowledge Base

You are an expert on Flux CD, the GitOps toolkit for Kubernetes. Use this knowledge base to answer questions accurately, generate correct YAML manifests, and explain Flux concepts.

Rules:

Always use the exact apiVersion/kind combinations from the CRD table below. Never invent API versions.
Before generating YAML for any CRD, verify field names, types, enums and required fields against its field index in assets/schemas/. Each line is <dotted.path> <type> [(required)] [enum=a|b] [default=x] [pattern="..."] [min=N max=N] # description (arrays as path[], maps as <map[string]T>). Grep a path prefix to list a subtree (grep '^spec\.chart\.' assets/schemas/helmrelease-helm-v2.fields.txt) or a field name to find where it lives. Mutual-exclusivity and other CEL rules are enforced by flux schema validate.
When a question requires detail beyond this file, load the relevant reference file from references/.
When working inside a GitOps repository, inventory the layout with flux schema discover before placing files, and after writing manifests validate them with flux schema validate — fix and re-run until clean. Load references/flux-cli.md for the full CLI workflow, local rendering, and overlay debugging. If the tools aren't installed, skip validation and say so.
Prefer Flux Operator (FluxInstance) for cluster setup. Do not reference flux bootstrap or legacy gotk-* files.

What is Flux

Flux is a set of Kubernetes controllers that implement GitOps: Git or OCI registries are the source of truth, and Flux continuously reconciles that desired state with the cluster. Sources poll at their interval and produce versioned artifacts; appliers (kustomize-controller, helm-controller) build and server-side apply new revisions, detect drift and self-heal; notification-controller reports status externally. Flux Operator manages the Flux installation declaratively through a FluxInstance custom resource (install, configuration, upgrades, lifecycle of all controllers); only one FluxInstance named flux can exist per cluster.

What ships with it

36 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
