A deployment skill for putting a bex application into a Kubernetes cluster, a system that runs and manages containers. It can use a render.yaml or legacy bex.yml file, or deploy the included sample app, then check whether the application becomes ready.

Use it to preview a generated application configuration, deploy an app to the current Kubernetes cluster, and verify its phase, revision, and URL.

It removes the need to manually apply the application configuration and repeatedly inspect the rollout. It also requires the relevant cluster configuration and BEX API credentials to be available.

SkillSpector: 3 findings, 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 10
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.

high Tool Misuse · line 16
Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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	$0.00056	$0.00566
Opus 5.5	$0.00022	$0.00226
Sonnet 5.5	$0.00011	$0.00113
Haiku 4.5	$0.00006	$0.00057

Security

Grade A, and why

deploy-app scanned grade A with 1 finding 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.

What it actually says

Deploy an App and verify it end-to-end. Use KUBECONFIG=infra/local/bex.kubeconfig if no other cluster is targeted.

Requires BEX_API_URL and BEX_API_TOKEN in the environment (scripts/app-apply.sh reads them and fails with set BEX_API_URL if unset — both are client-supplied, not in .env.example; BEX_API_PUBLIC_URL in .env.example is the unrelated backend DeployHook origin). BEX_API_TOKEN is the Hydra-issued Bearer token (API key minted via /v1/api-keys), not the removed static shared secret. Optional BEX_OWNER_ID, BEX_REPO, BEX_BRANCH narrow the deploy.

If $ARGUMENTS is a path to a render.yaml (or legacy bex.yml alias — canonical is render.yaml, see scripts/app-apply.sh), apply it with DRY_RUN=1 bash scripts/app-apply.sh $ARGUMENTS first and show the generated App CR, then bash scripts/app-apply.sh $ARGUMENTS to deploy. If $ARGUMENTS is a directory, pass the directory — the script discovers render.yaml then bex.yml inside it. Otherwise apply the sample: kubectl apply -f examples/whoami-app.yaml.
Watch until ready: poll kubectl get apps.app.bex.co <name> -o jsonpath='{.status.phase} {.status.revision} {.status.url}' until phase is Ready (timeout ~3 minutes; on timeout, show kubectl describe apps.app.bex.co <name> and the operator logs kubectl -n bex-system logs deploy/bex-controller-manager --tail=50).
If status.url is set and resolvable, curl -fsS it (use --resolve/-k only if the local mock has no real DNS/TLS) and show the response status.
Report: App name, phase, revision, url, and where the pods landed (kubectl get pods -l app.bex.co/app=<name> -o wide).

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.

deploy-app is a skill published in the GitHub repository bex-co/bex (574 stars, last pushed today), licensed Apache-2.0. It adds 56 tokens to every session and 566 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
