argo-cd-knowledge-patch

A reference guide for Argo CD, a tool that deploys and keeps applications in sync with their desired setup. It covers configuration, upgrades, repositories, security, health checks, and operations.

In plain words
What is it for?
Use it when writing Applications or ApplicationSets, connecting repositories, using the CLI or API, or changing Argo CD security, health, or monitoring behavior.
Why use it?
It helps avoid relying on outdated or incomplete knowledge when changing an Argo CD setup.

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.

Security

Grade A, and why

argo-cd-knowledge-patch 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 3d 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.

Argo CD Knowledge Patch

Use this skill when upgrading or configuring Argo CD, writing Applications or ApplicationSets, integrating repositories and Source Hydrator, operating the CLI or API, or updating security, health, and observability behavior. Start with the behavior changes below, then open the reference for the task at hand.

Reference index

Reference Topics
Applications, projects, and sync Comparison, reconciliation, automated sync, sync windows, apply and replace behavior
ApplicationSets and generators Progressive Sync, generators, concurrency, namespaces, deletion, status and UI
Repositories, rendering, and hydration Helm, Git, OCI, Kustomize, plugins, webhooks, Source Hydrator and Source Integrity
CLI, API, and extensions Diff and resource commands, plugins, namespaces, core mode, typed events and UI extensions
Security, identity, and RBAC Authorization defaults, tokens, SSO, impersonation, Secret masking and static assets
Operations and observability Repo-server, Redis, transport, probes, metrics, tracing, logging and caching
Resource health and actions Built-in health coverage, corrected states, scaling, rollout and lifecycle actions

Upgrade-critical behavior changes

Revalidate authorization

  • Log access enforces RBAC by default. Give every role that reads pod logs an explicit permission and test both CLI and API access.
  • Fine-grained RBAC inheritance is disabled by default. Policies that granted an Application permission and expected it to flow to resources need review.
  • User-defined roles and policies undergo referential-integrity checks. Repair dangling references rather than relying on permissive loading.
  • Server operations can use impersonation, including logs and deletes. Treat any compatibility switch that relaxes strict enforcement as a temporary migration control.

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.

argo-cd-knowledge-patch is a skill published in the GitHub repository Nevaberry/nevaberry-plugins (24 stars, last pushed 6d ago), licensed MIT. It adds 11 tokens to every session and 1,870 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
