Motion Clinic — API

Paste the Dart, get a structured motion review.

API tokens Open the app

Review your Flutter animations from your own scripts

Send Flutter animation code — the widgets and State classes that own AnimationControllers, implicit Animated* widgets, Hero pairs, custom route transitions, gesture-driven physics, a pubspec.yaml excerpt, or several files concatenated — and get back one JSON object: a motion posture, the inventory of every widget, controller, animation, hero, route and package with its role, prioritized findings across lifecycle, strategy, performance, correctness, transitions, physics, accessibility and hygiene, each with a corrected Dart 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 your animation code, a motion-design refresh about to ship, or a pre-merge 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 motion-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 itself is produced by the gpt-terra model. Estimates are free; runs are metered against your credit balance. There is a single run task — one paste of Dart code in, one review out, no follow-up calls and no session state to carry.

StatusMeaning
401Missing or expired token — create a new session.
402Not enough credits — top up at skillsafe.ai/account/credits.
403The token isn't allowed to do this (e.g. a guest reviewing a very large paste).
404Unknown job or record id.
5xxTransient 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

POST /guest

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":"motion-clinic"}' | jq -r '.data.token'
token = api("POST", "/guest", {"slug": "motion-clinic"})["token"]
const { token } = await api("POST", "/guest", { slug: "motion-clinic" });
var guest struct{ Token string `json:"token"` }
err := call("POST", "/guest", map[string]string{"slug": "motion-clinic"}, &guest)
String envelope = api("POST", "/guest", """
    {"slug":"motion-clinic"}""");
// token is at data.token in the returned JSON
token = api("POST", "/guest", { slug: "motion-clinic" })["token"]
$token = api("POST", "/guest", ["slug" => "motion-clinic"])["token"];
var guest = await SkillSafe.ApiAsync(HttpMethod.Post, "/guest",
    new { slug = "motion-clinic" });
var token = guest.GetProperty("token").GetString();

The app stores this browser's token under the localStorage key skillsafe_app_token:motion-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

GET /me

Returns subject_type ("user" or "guest"), subject_id and your credits balance. Check this before reviewing a large paste.

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

POST /estimate

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 lib/data/ tree in and want a ceiling before spending credits.

Input fieldTypeNotes
codestring, requiredThe Dart/Flutter sources, exactly as they sit on disk: widgets and State classes that own controllers, implicit Animated* widgets, Hero pairs, route builders, gesture handlers, pubspec.yaml — one file or several concatenated, a // filename comment line between them helps the reviewer name things. This is the model's only evidence — nothing is read from your repository, a running app or a device. Pastes longer than 100,000 characters are clipped middle-out, with a // [... clipped ...] comment showing where. At least 60 characters are needed for a review.
surfacestringimplicit | explicit | hero | physics | staggered | mixed | unknown — the main animation approach in play, which sets the idioms the reviewer leans on. A physics rig is judged by simulation idioms (unbounded controller, velocity conversion), not tween rules. If the code itself clearly shows the approach (an AnimationController field, a Hero pair), the code wins.
concernstringgeneral | lifecycle-leaks | performance-jank | strategy-fit | transitions-routes | gestures-physics — 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.
contextstring, optionalExtra context: what the app is, what the motion is supposed to communicate, target devices and frame budget, whether dispose() or the rest of a State class lives outside the paste, and any gap you have already chosen to accept. Clipped at 20,000 characters.
prescan_factsobject, optionalWhat a client-side scanner mechanically matched in the code: {"units": [], "flags": []}. Each entry is {id, label}. Unit ids look like unit:state/promoscreenstate, unit:controller/_fadecontroller or unit:hero/tag-deal-card; flag ids are <check>:<name> across eleven families — no-dispose:promoscreenstate, missing-vsync:promoscreenstate-20, no-ticker-mixin:badgestate, single-ticker-multi:promoscreenstate, timer-frame-math:line-98, setstate-listener:promoscreenstate, builder-no-child:promoscreenstate-949, opacity-not-fade:promoscreenstate, forward-in-build:promoscreenstate, hero-literal-tag:deal-card, missing-duration:promoscreenstate. 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_notestring, optionalOnly 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 {"units": [{"id": "unit:state/_pulsebadgestate", "label": "state \"_PulseBadgeState\""}], "flags": [{"id": "no-dispose:_pulsebadgestate", "label": "_PulseBadgeState never disposes _c"}, {"id": "setstate-listener:_pulsebadgestate", "label": "rebuilds the whole tree per frame via addListener + setState"}]} 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

POST /run
GET /jobs/{job_id}

/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 Dart fragment). Always send an Idempotency-Key header so a network retry can't start a second, double-charged run. 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.

JOB_ID=$(curl -s -X POST "$API/run" \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -H "Idempotency-Key: mc-$(date +%s)" \
  -d @input.json | jq -r '.data.job_id')

while :; do
  JOB=$(curl -s "$API/jobs/$JOB_ID" -H "Authorization: Bearer $TOKEN")
  STATUS=$(echo "$JOB" | jq -r '.data.status')
  [ "$STATUS" = "succeeded" ] || [ "$STATUS" = "failed" ] && break
  sleep 2
done

# unwrap the review once, then read it
echo "$JOB" | jq -r '.data.output.output' > 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 code alone: findings cite only classes, controllers, widgets and packages that actually appear in code, and something that is simply absent (no dispose(), no vsync, no ticker mixin, no duration) is reported against the closest real unit or against (missing from the paste). Where the code 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 paste — well-built motion code may honestly yield two or three, and findings is never empty.

FieldTypeMeaning
review_namestringA short title naming the codebase, taken from the code's own naming — e.g. promo screen motion — Flutter review.
posturestringwell-built | tune-recommended | at-risk. See the table below.
verdictstringOne sentence justifying the posture and naming the single most important change.
exec_summarystringTwo or three paragraphs, separated by blank lines, on the dominant themes across the paste.
assumptionsstring[]Explicit assumptions filling gaps the code left open. Read these first — a wrong assumption invalidates the findings built on it.
open_questionsstring[]Questions whose answers would change the ranking.
inventoryarray{kind, name, group, role} — every unit the review parsed out of the paste and the part it plays. kind is the unit type (widget, state, controller, animation, hero, route, gesture, package, other); name is the class, field or package name; group is the // filename comment the unit sits under, or -. Every widget and State class that participates in motion, every controller and named Animation field, every Hero, custom route and animation-relevant package is inventoried; classes that never touch animation are skipped.
findingsarrayThe prioritized findings table — ids MC-001, MC-002, … in sequence, at least one entry. Columns are listed below.
coverage_checkarray{id, addressed, note} — one entry per prescan_facts.flags id you sent, each appearing exactly once. See the semantics below.
quick_winsstring[]One-line changes worth doing immediately, ahead of any planning. May be empty when nothing here is a one-liner.
focus_areasarray{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.
summarystringClosing paragraph: what to fix first, and what risk remains after that.

The three posture values:

postureWhat it means
well-builtThe motion system holds up as written: one disposed controller per ticker, correct mixins and vsync, rebuilds scoped by AnimatedBuilder/AnimatedWidget with the child parameter used, dedicated transition widgets, data-driven Hero tags, physics driven from gesture velocity. Findings still exist, but they are additions and refinements — reduced-motion support, test coverage with WidgetTester.pump, extracting a reusable transition — not blockers. Genuinely well-built motion code lands here rather than having severity manufactured for it.
tune-recommendedThe shape is right or recoverable, but named gaps should be closed before this grows more screens — a whole-tree setState listener where an AnimatedBuilder belongs, an AnimatedBuilder rebuilding its static subtree every frame, an explicit controller rig doing what an implicit widget does in one line, Opacity animated by rebuild, a literal Hero tag waiting to collide.
at-riskAt least one thing crashes, leaks or burns battery as written: a second controller on SingleTickerProviderStateMixin (a runtime throw), forward() on a duration-less controller, a controller that is never disposed on a screen users keep open, a Timer.periodic loop that keeps firing offscreen and is never cancelled, an animation restarted inside build() on every rebuild.

Each entry in findings:

ColumnMeaning
idSequential MC-001, MC-002, … — the stable handle referenced from focus_areas[].finding_ids.
categorylifecycle | strategy | performance | correctness | transitions | physics | accessibility | hygiene. Weighted by the concern you sent, but never restricted to it.
severitylow | medium | high — how bad it is when it bites.
likelihoodlow | medium | high — how likely it is to bite.
prioritycritical | high | medium | low — severity by likelihood. critical is reserved for something that crashes at runtime as written, leaks tickers on a screen users keep open, or rebuilds a heavy tree every frame on a core interaction path, so sort on this field and work top-down. This is also the field to gate a pipeline on.
resourceThe unit this is about — e.g. class _PulseBadgeState or controller _fadeController — always something that appears in code, or the literal (missing from the paste) when the finding is about an absent guard or mixin.
problemWhat is wrong, in this code specifically.
impactWhat happens in the shipped app because of it — the leaked ticker draining battery offscreen, the runtime crash from a second controller on a single ticker, the whole-tree rebuild at 60fps, the animation restarting on every rebuild, the broken hero pairing.
fixThe concrete change to make — not "clean up the data layer".
snippetA corrected Dart or pubspec.yaml fragment you can paste: the fixed method, State class skeleton or route builder, correctly indented, not the whole file. Empty string when a snippet would add nothing.

coverage_check semantics:

CaseWhat you get
Every flag id you sentEach 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.units are not reconciled here — they shape the inventory instead.
addressed: trueThe flag is covered by the review; note names the finding id that covers it.
addressed: falseThe flag was deliberately set aside; note gives the reason — a check that fired but is not a real problem for this code (a dispose() that lives outside the paste per context, a deliberately unbounded physics controller, a debug-only widget).
Nothing sentOmit prescan_facts, or send the two empty arrays, and coverage_check comes back empty. The rest of the review is unaffected.

A small, realistic result for the _PulseBadgeState snippet above, sent with the prescan flags from the note in step 3 as well, trimmed for length:

  "review_name": "pulse badge motion — Flutter review",
  "posture": "at-risk",
  "verdict": "The pulse controller repeats forever and is never disposed, and its listener is

                   Two themes carry the findings: the controller outlives the widget because
                   nothing disposes it, and the rebuild path is the most expensive one available -
                   a whole-subtree setState per frame, with a new listener stacked on every

This is AI-generated review from pasted text, not a production sign-off: it sees only the code you sent, never the running app, its frame timings or a profiler trace. Check assumptions and open_questions before you act on the rankings, validate every snippet with dart analyze and your tests, and keep a human reviewer in the loop.

Step 5 — Stream the review as it is written

POST /run-stream

/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 fragments 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.

EventPayloadMeaning
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.
