Review your Kubernetes manifests from your own scripts
Send Kubernetes YAML — one document or a whole bundle separated by --- —
and get back one JSON object: a production-readiness posture, the inventory of every resource
with its role, prioritized findings across security, reliability, scaling, cost, GitOps,
observability and hygiene, each with a corrected YAML fragment, quick wins, and the focus
areas to work through first. Everything this app does goes through the SkillSafe App API
— plain JSON over HTTPS — so you can hang a review off a pull request that touches
k8s/, a Helm template render, a kustomize build, or a pre-promotion
gate. Every code step below is shown in cURL, Python, JavaScript, Go, Java, Ruby, PHP and C#;
pick a language once and the whole page follows.
Basics
Base URL: https://api.skillsafe.ai/v1/app-api, app slug
k8s-clinic. Every request sends
Authorization: Bearer <token> and JSON bodies with
Content-Type: application/json. Responses are wrapped in an envelope:
{"data": …} on success, {"error": {"code", "message"}} on failure.
The review is produced by whichever model /estimate reports in its model
and model_alias fields — read it from there rather than hardcoding a name, since
the alias repoints as new models ship. Estimates are free;
runs are metered against your credit balance. There is a single run task — one bundle of
manifests in, one review out, no follow-up calls and no session state to carry.
| Status | Meaning |
|---|---|
401 | Missing or expired token — create a new session. |
402 | Not enough credits — top up at skillsafe.ai/account/credits. |
403 | The token isn't allowed to do this (e.g. a guest reviewing a very large bundle). |
404 | Unknown job or record id. |
5xx | Transient platform error — retry with backoff. |
Browsers enforce CORS for this API, so run these examples from a server, script or terminal — not from another website's frontend.
Step 0 — A tiny client
Every task below is a single HTTP call, so start with a short helper that adds the auth
header, sends JSON and unwraps the data envelope. The later steps reuse it.
export API="https://api.skillsafe.ai/v1/app-api"
export TOKEN="YOUR_TOKEN" # see step 1
# every call looks like:
# curl -s "$API/..." -H "Authorization: Bearer $TOKEN" [-d '{json}']
# jq is used below to pull fields out of the {"data": ...} envelope

Step 1 — Get a token
A guest token lets you check balances and estimate costs for free. For metered review runs
billed to your own account, use your personal token: open the
token page, sign in with SkillSafe, and press
Copy shell export — it puts export SKILLSAFE_TOKEN="…" on your
clipboard, which every example below reads. Treat the token like a password: it can spend
your credits. For fully headless scripts, POST /guest mints a guest token with
no browser involved.
curl -s -X POST "$API/guest" \
-H "Content-Type: application/json" \
-d '{"slug":"k8s-clinic"}' | jq -r '.data.token'
token = api("POST", "/guest", {"slug": "k8s-clinic"})["token"]
const { token } = await api("POST", "/guest", { slug: "k8s-clinic" });
var guest struct{ Token string `json:"token"` }
err := call("POST", "/guest", map[string]string{"slug": "k8s-clinic"}, &guest)
String envelope = api("POST", "/guest", """
{"slug":"k8s-clinic"}""");
// token is at data.token in the returned JSON
token = api("POST", "/guest", { slug: "k8s-clinic" })["token"]
$token = api("POST", "/guest", ["slug" => "k8s-clinic"])["token"];
var guest = await SkillSafe.ApiAsync(HttpMethod.Post, "/guest",
new { slug = "k8s-clinic" });
var token = guest.GetProperty("token").GetString();
The app stores this browser's token under the localStorage key
skillsafe_app_token:k8s-clinic, on the app's own origin. The
token page reads and manages it for you — you never need
to open developer tools.
Step 2 — Check who you are and your balance
Returns subject_type ("user" or "guest"),
subject_id and your credits balance. Check this before reviewing a
large bundle.
curl -s "$API/me" -H "Authorization: Bearer $TOKEN" | jq '.data'
me = api("GET", "/me")
print(me["subject_type"], me["credits"])
const me = await api("GET", "/me");
console.log(me.subject_type, me.credits);
var me struct {
SubjectType string `json:"subject_type"`
Credits int64 `json:"credits"`
}
err := call("GET", "/me", nil, &me)
String envelope = api("GET", "/me", null);
// data.subject_type, data.credits
me = api("GET", "/me")
puts "#{me["subject_type"]}: #{me["credits"]} credits"
$me = api("GET", "/me");
echo "{$me['subject_type']}: {$me['credits']} credits\n";
var me = await SkillSafe.ApiAsync(HttpMethod.Get, "/me");
Console.WriteLine($"{me.GetProperty("subject_type")}: {me.GetProperty("credits")} credits");
Step 3 — Estimate the cost
Send exactly the input you would send to /run; the response's
hold_credits is the worst-case cost. Nothing is charged and no job is created,
so estimating is free — useful when you are piping a whole kustomize build
in and want a ceiling before spending credits.
| Input field | Type | Notes |
|---|---|---|
manifests | string, required | The Kubernetes YAML, exactly as you would apply it. One document or many, separated by a line containing only ---. This is the model's only evidence — nothing is read from a live cluster. Bundles longer than 100,000 characters are clipped middle-out, with a # [... clipped ...] comment showing where. At least 60 characters are needed for a review. |
environment | string | managed-cloud (EKS / AKS / GKE) | on-prem | openshift | unknown — changes what the reviewer may assume is available: a cloud LoadBalancer and a default CSI StorageClass on managed cloud, SecurityContextConstraints and Routes on OpenShift, neither on bare metal. |
concern | string | general | security | reliability | cost | gitops — the review emphasis. It weights the findings and the summary, but it is emphasis and not exclusivity: a high-severity finding from another category is never suppressed. |
context | string, optional | Extra context: cluster version, how these manifests are delivered (kubectl, Helm, Kustomize, ArgoCD, Flux), what an admission controller or service mesh already enforces, expected scale, and any gap you have already chosen to accept. Clipped at 20,000 characters. |
prescan_facts | object, optional | What a client-side scanner mechanically matched in the YAML: {"resources": [], "flags": []}. Each entry is {id, label}. Resource ids look like res:deployment/web; flag ids are <check>:<name> — img-latest:web, no-limits:web, no-probes:web, one-replica:web, privileged:web, run-as-root:web, host-network:worker, host-pid:worker, no-seccontext:web, exposed:web, plain-secret:web, no-namespace:web. Every flag id you send comes back in coverage_check. The web UI fills this from its own scan; API callers may omit the field or send the two empty arrays. |
retry_note | string, optional | Only set by the app's automatic reformat retry when a first reply was not valid JSON. Leave it out. |

prescan_facts.flags is how you make the review answer for things you already
know about. Send {"resources": [{"id": "res:deployment/web", "label": "Deployment/web"}],
"flags": [{"id": "img-latest:web", "label": "web uses :latest"}]} and every flag id
comes back in coverage_check — addressed by a finding, or set aside with
the reason. Nothing you flag is silently dropped, which makes it the field to assert on in a
CI check.
Step 4 — Run the review and wait for the result
/run takes the same input as /estimate, places a credit hold and
returns a job_id. Poll /jobs/{job_id} every 1–2 seconds
until status is succeeded or failed (a run typically
takes 30–90 s, since every finding carries a corrected YAML fragment). Always send
an Idempotency-Key header so a network retry can't start a second,
double-charged run — but generate a fresh key for every review you
actually want performed. The key is not a per-script constant: re-sending one the server has
already seen replays the stored result and never runs the model again, so a hardcoded literal
turns your second review of an edited manifest into a silent replay of the first. Where a
sample below sets the header inline it derives a fresh value per invocation; where it calls
the shared api()/call() helper from step 1, add the header
there so every /run and /run-stream it makes carries one. The
review is in output — usually nested as
output.output, and as a JSON string, so parse defensively. The samples
below print the posture, the inventory, the prioritized findings and the focus areas, then
save the whole object to review.json.

The model is asked for one JSON object and nothing else, but a stray code fence or preamble
is always possible. Strip a leading ```json fence, take the text between the
first { and the last }, and only then parse — that is what
the app does before it falls back to a retry_note reformat run.
The review object — output schema
One JSON object, always the same shape. Every array is present, and the review is grounded in
the pasted YAML alone: findings cite only resources that actually appear in
manifests, and a resource that is simply absent (no NetworkPolicy, no
PodDisruptionBudget, no HPA) is reported against the closest real resource or against
(missing from the set). Where the YAML is silent on something that changes the
verdict you get an entry in assumptions and, if it would change the ranking, in
open_questions. Expect five to fifteen findings on a typical bundle — a
well-built set may honestly yield two or three, and findings is never empty.
| Field | Type | Meaning |
|---|---|---|
review_name | string | A short title naming the workload, taken from the manifests' own naming — e.g. storefront bundle — manifest review. |
posture | string | production-ready | hardening-recommended | not-production-ready. See the table below. |
verdict | string | One sentence justifying the posture and naming the single most important change. |
exec_summary | string | Two or three paragraphs, separated by blank lines, on the dominant themes across the set. |
assumptions | string[] | Explicit assumptions filling gaps the YAML left open. Read these first — a wrong assumption invalidates the findings built on it. |
open_questions | string[] | Questions whose answers would change the ranking. |
inventory | array | {kind, name, namespace, role} — every resource the review parsed out of the bundle and the part it plays. namespace may be empty, which itself is usually a finding. |
findings | array | The prioritized findings table — ids KC-001, KC-002, … in sequence, at least one entry. Columns are listed below. |
coverage_check | array | {id, addressed, note} — one entry per prescan_facts.flags id you sent, each appearing exactly once. See the semantics below. |
quick_wins | string[] | One-line changes worth doing immediately, ahead of any planning. May be empty when nothing here is a one-liner. |
focus_areas | array | {area, why, finding_ids} — what to work through first, one sentence tied to the review, and the finding ids that motivate it. Every id in finding_ids exists in findings. |
summary | string | Closing paragraph: what to fix first, and what risk remains after that. |
The three posture values:
| posture | What it means |
|---|---|
production-ready | The manifests hold up as written: pinned images, a resource contract, probes, a security context, sane replica and rollout settings. Findings still exist, but they are additions and refinements, not blockers. A genuinely well-built bundle lands here rather than having severity manufactured for it. |
hardening-recommended | The shape is right, but named gaps should be closed before this carries real traffic — a missing probe, no PodDisruptionBudget, a permissive default securityContext, limits without requests. |
not-production-ready | At least one thing would cause an outage, an unreproducible rollout, or a real security exposure as written: a floating :latest tag, a literal secret, a privileged or host-network pod, a single replica behind live traffic. |
Each entry in findings:
| Column | Meaning |
|---|---|
id | Sequential KC-001, KC-002, … — the stable handle referenced from focus_areas[].finding_ids. |
category | security | reliability | scaling | cost | gitops | observability | hygiene. Weighted by the concern you sent, but never restricted to it. |
severity | low | medium | high — how bad it is when it bites. |
likelihood | low | medium | high — how likely it is to bite. |
priority | critical | high | medium | low — severity by likelihood. critical is reserved for something exploitable or outage-causing as written, so sort on this field and work top-down. This is also the field to gate a pipeline on. |
resource | The Kind/name this is about — always something that appears in manifests, or the literal (missing from the set) when the finding is about an absent resource. |
problem | What is wrong, in this YAML specifically. |
impact | What happens on a real cluster because of it. |
fix | The concrete change to make — not "add validation". |
snippet | A corrected YAML fragment you can paste: the fixed block, correctly indented, not the whole document. Empty string when a snippet would add nothing. Secret values are never echoed — a placeholder appears instead. |
coverage_check semantics:
| Case | What you get |
|---|---|
| Every flag id you sent | Each prescan_facts.flags id appears in coverage_check exactly once. Nothing you flagged is silently dropped, which makes this the field to assert on in a CI check. Ids in prescan_facts.resources are not reconciled here — they shape the inventory instead. |
addressed: true | The flag is covered by the review; note names the finding id that covers it. |
addressed: false | The flag was deliberately set aside; note gives the reason — a check that fired but is not a real problem for this workload (a single replica on a batch Job, a LoadBalancer that is the intended ingress). |
| Nothing sent | Omit prescan_facts, or send the two empty arrays, and coverage_check comes back empty. The rest of the review is unaffected. |

This is AI-generated review from YAML text, not a production sign-off: it sees only what you
sent, never the live cluster, the admission policies or the CNI. Check
assumptions and open_questions before you act on the rankings,
validate every snippet against your own schema (kubectl apply --dry-run=server),
and keep a human reviewer in the loop.
Step 5 — Stream the review as it is written
/run-stream takes exactly the same body as /run but answers with
server-sent events, so you can show progress instead of a spinner — useful here
because a full findings table with corrected YAML makes for a long reply. This app's own
progress panel is this endpoint. Events are separated by a blank line; each has an
event: line and a data: line carrying JSON.
| Event | Payload | Meaning |
|---|---|---|
job | {job_id, status} | Sent once, when the job is accepted — show "starting". |
delta | {text} | A chunk of the reply, in order. Append it; the accumulated length is your only progress signal (the total is not known in advance). The app advances its step list by watching for the "review_name", "inventory", "findings", "coverage_check" and "focus_areas" keys as they arrive. |
done | {job_id, status, charged_credits, output} | The final, authoritative result — read the review from output.output rather than trusting concatenated deltas, and the settled price from charged_credits. |
error | {code, message} | Replaces done when the run fails. |

In a browser, the native EventSource only speaks GET, and this endpoint is a
POST — read the fetch response body incrementally, as the JavaScript
sample above does. On an idempotent replay the server may answer with a plain JSON
envelope instead of an event stream; check the Content-Type before you start
parsing frames.
