Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00097 | $0.00830 |
| Opus 5 | $0.00048 | $0.00415 |
| Sonnet 5 | $0.00019 | $0.00166 |
| Haiku 4.5 | $0.00010 | $0.00083 |
Grade A, and why
argocd-gitops-review 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Argo CD GitOps Review
Purpose
Review Argo CD Application, AppProject, ApplicationSet, sync windows, RBAC, and the central argocd-cm / argocd-rbac-cm configuration against blast radius, drift handling, and least-privilege sync identity. Argo CD's controller defaults to cluster-admin permissions on every destination cluster — the security posture lives in AppProject boundaries, sync impersonation, and explicit RBAC, not in the controller defaults.
Lean operating rules
- Prefer live cluster evidence (
kubectl get applications,appprojects,applicationsets -n argocd -o yamlplus theargocd-cmandargocd-rbac-cmConfigMaps) when the active client exposes it; otherwise fall back to official Argo CD documentation and sanitized YAML from the user. - Separate confirmed facts from inference. If sync history, current health, or RBAC binding state was not queried, say so.
- Treat
application.sync.impersonation.enabled: false(default) in production as a critical finding — every sync runs as the controller's cluster-admin ServiceAccount. - Treat
AppProjectwithsourceRepos: ['*']anddestinations: ['*']as a wide-blast-radius finding — any commit in any repo can deploy anywhere. - Treat
automated.prune: true+automated.selfHeal: trueon production Applications as critical without an explicit allowlist of authorized Git refs and a tested rollback runbook — Git divergence becomes irreversible deletion. - Challenge
ApplicationSetgenerators that include unbounded clusters (clusters: {}) or label selectors with no exclusion — one mis-labeled cluster joins the rollout. - Challenge
syncOptions: ['Replace=true']andsyncOptions: ['ServerSideApply=false']on stateful resources — Replace deletes-then-creates, breaking PVC bindings. - Keep the answer scoped, reversible, least-privilege, and explicit about blockers or unknowns.
References
Load these only when needed:
- Evidence path and tooling — use when choosing live cluster evidence, confirming Argo CD install state and version, or switching to documentation mode.
- Workflow and output contract — use when executing the full review, applying stress checks on Application / AppProject / ApplicationSet, or formatting the final answer.
- Official sources — use when you need the detailed Argo CD documentation list, RBAC syntax, and grounded insights from the project.
What ships with it
4 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.
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.

argocd-gitops-review is a skill published in the GitHub repository VincentChuWaiChow/vanguard-frontier-agentic (22 stars, last pushed today), licensed Apache-2.0. It adds 97 tokens to every session and 830 once invoked, about $0.0005 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 2026-09-04.
