scenario-quality-gate — Claude Code skill: image quality checks
This skill scores a finished Scenario image and returns a pass, warn or fail verdict with a 0 to 100 score. Handy when a generation needs a check before it ships.
npx skills add scenario-labs/skills --skill scenario-quality-gate -a claude-codeWhat scenario-quality-gate does
Everything runs through one tool, asset_quality_gate_run. It scores AI quality, and when a team or project has a brand brief configured, it adds a brief-compliance check on top. The response carries verdict, overallScore, aiQualityScore, briefComplianceScore, plus reasons and suggestions lists per dimension. Image assets only.
You do not call it directly. Pull the schema with scenario_tools_search, then run it through scenario_tool_execute_write as {name: "asset_quality_gate_run", parameters: {...}}, with scope ids inside parameters. The read executor rejects it by lane and points at the right one. Reconnecting with ?toolsets=full is the other route.
Quality Gate is an Enterprise add-on. If it is not enabled for the team, the call fails cleanly and retrying never clears it. The skill tells you to fall back to an asset_analyze review from the scenario-asset-analysis skill and say so. On cost: a plain call is free only when a usable verdict is already stored, otherwise that same call quietly escalates to a billed analysis. Probe with dry_run: true first if spend needs approval.
What it helps with
- filter out broken generations before publishing
- check an image against a configured brand brief
- gate a whole batch of assets
- see the price of a new analysis before spending
- regenerate an image until it clears the gate
Example prompts for the agent
- check the quality of this Scenario image and tell me what is wrong
- run a dry_run of asset_quality_gate_run and show me the price
- gate this batch and keep only the assets that passed

# Scenario Quality Gate
## Overview
One tool, `asset_quality_gate_run`, scores a finished image asset and returns a `pass`/`warn`/`fail`
verdict with 0 to 100 scores and per-dimension lists of `reasons` and `suggestions`: an AI-quality
check always, plus brand-brief compliance when the team or project has a brief configured. Image
assets only. Quality Gate is an Enterprise add-on: when it is not enabled for the team the call
fails cleanly, so detect that, fall back to an `asset_analyze` review (see
`scenario-asset-analysis`), and say so. Retrying never clears it.
The tool is catalog-only and write-class: get the schema with `scenario_tools_search`, then run it
through `scenario_tool_execute_write` with `{name: "asset_quality_gate_run", parameters: {...}}`,
scope ids inside `parameters` (the read executor rejects it by lane and names the right one). Or
reconnect with `?toolsets=full`. Connection and scope: see the `scenario` skill. If a sibling skill
named here is missing from your available skills, ask the user to install it
(`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and
flag the gap.
## Quick reference: what a call costs
| Call | What happens | Cost |
| --------------------------------- | ------------------------------------------------------------------------ | -------------------------------------------------------------------------- |
| Plain call, usable verdict stored | Returns the stored verdict, `source: "stored"` | Free (the response carries no `creativeUnitsCost`) |
| Plain call, no usable verdict | Runs a new analysis and stores the verdict, `source: "new_analysis"` | Billed; the response carries `creativeUnitsCost` (1 CU as of this writing) |
| `rerun: true` | New analysis that replaces the stored verdict | Billed |
| `dry_run: true` | Nothing runs; returns the price of a new analysis as `creativeUnitsCost` | Free |
A plain call is a read only when a usable verdict already exists; otherwise the same call silently
escalates to the billed analysis. "No usable verdict" covers both never-scored and a stored `error`
result. When spend needs approval first, probe free: `dry_run: true`, or `asset_get`, whose
`qualityGate` field carries the verdict and scores when one is stored (summary only; the stored
`reasons` and `suggestions` come back through the tool, still free). `sensitivity` (`low`, `medium`,
`high`; default is the team or project setting) shapes new analyses only and is ignored on stored
reads. `rerun: true` is for after the brief or the sensitivity changed, nothing else: it re-bills
and overwrites.
## Reading the verdict
The response is `source` plus `quality_gate`: `verdict`, `overallScore`, `aiQualityScore`,
`briefComplianceScore`, `sensitivity`, `appliedBriefIds`, and `details`. With no brief configured
the compliance dimension is absent entirely (`appliedBriefIds: []`, `overallScore` equals
`aiQualityScore`); with one, `details.briefCompliance` sits beside `details.aiQuality`, each
carrying a `score` and lists of `reasons` and `suggestions`, usually several of each.
## Turning the verdict into a better image
A verdict alone only sorts assets. The gate earns its cost when the feedback drives the next
attempt:
- `reasons` name concrete flaws ("elongated finger anatomy on the left hand", "background gradient
off the brief's palette"). Use them to pick the fix path per flaw: a local defect on an otherwise
approved image is a masked inpainting pass (`scenario-image`); a global one is a regeneration.
- `suggestions` are written as edit instructions, often worded for manual retouching. Apply all that
fit, not just the first: translate them into the next `model_run` prompt or parameters, or into
the edit instruction.
- A regenerated image is a new asset, so a plain call scores it. `rerun` is never part of the loop.
It may even come back pre-scored for free: teams with auto-detect enabled
(`qualityGateAutoDetect: true` on their `teams_list` row) score new generations automatically.
- When a round repeats the same flaw classes at an unmoved score, rewording will not fix them:
switch models (`recommend` again) or repair the flaw with a masked edit before spending another
round.
- Fix the exit bar and a round cap up front: `verdict: "pass"` by default, or a score target the
user names (`overallScore` at or above 90, say; the named bar then outranks a bare `pass`), and
three rounds unless told otherwise, since every round bills a generation plus an analysis. At the
cap, or when a round stops moving the scores, stop: report the best asset with its remaining flaws
and ask before spending more rounds; unattended, deliver that best asset and flag the miss.
`scenario-refine-loop` carries the loop discipline beyond the gate: one variable per round,
regeneration from the approved baseline, and fix routing when the criteria go past the brief.
## What the verdict does not cover
The gate is an artifact detector. Measured on real assets, three limits to design around:
- **Artifacts, not plausibility.** A panel whose car carried two different wheels, a whitewall on
one only, and no wheel arch above the rear tire scored 92 and `pass` at `sensitivity: "high"`,
with `reasons` praising the chrome rims that were the defect. What is impossible rather than ugly
needs a structural check of your own: counts and attachment (hands, fingers per hand, limbs,
wheels, each attached to one body), part to whole (a wheel sits inside an arch, a guard sits on
its own blade, a reflection sits under what casts it), and what carries the weight.
- **It has never seen your reference.** `briefCompliance` needs a configured brief, and a brief is
text, so no call can tell you this is not the same car or costume as the plate it was generated
from. Compare the asset against its reference yourself, item by item.
- **A composite averages its parts.** A 12-panel storyboard scored 88 and `pass` while one of its
panels was physically impossible. Score the unit you are willing to reject: split a composite with
`model_scenario-image-slicer`, score each part, repair only the failures, and recompose with
`model_scenario-compose-image`.
The score is also a weak signal that a structural repair landed: a broken panel and its corrected
replacement both scored 92, and only the `reasons` changed. Re-read the flaw list, do not watch the
number.
## Worked example: iterate a hero prop to pass
1. Generate per `scenario-image`: `model_run`, `jobs_wait`, collect the asset id.
2. `scenario_tools_search` with `query="quality gate"` once for the schema, then `dry_run: true` on
the first asset to surface the per-analysis price.
3. Score: `scenario_tool_execute_write` with
`{name: "asset_quality_gate_run", parameters: {asset_id, team_id, project_id}}`. It returns
`source: "new_analysis"` and a `quality_gate` carrying `verdict: "warn"`,
`briefComplianceScore: 58`, and `details.briefCompliance.suggestions` asking for the logo at the
top left and a flatter background.
4. Fold both suggestions into the prompt, regenerate, and score the new asset with a plain call (no
`rerun`).
5. `verdict: "pass"`: deliver, and file it (collections and tags per `scenario-asset-analysis`).
Later reads of any scored asset are free stored reads.
6. The brief changes next sprint: only then `rerun: true` on the assets that must be re-judged.
## Common mistakes
- Treating a plain call as a free read: without a usable stored verdict it silently runs and bills
the analysis. Probe with `dry_run` or `asset_get` first when the spend matters.
- Passing `rerun: true` out of habit: it re-bills verdicts that were free to read. Its one job is
refreshing after the brief or sensitivity changed.
- Expecting `briefComplianceScore` with no brief configured: `quality_gate` carries it and
`details.briefCompliance` only when `appliedBriefIds` is non-empty.
- Applying one suggestion and rescoring each time: the lists usually carry several fixes, and one
regeneration can absorb them all.
- Running it through `scenario_tool_execute_read`: write-class, rejected by lane.
- Scoring a video, 3D, or audio asset: image assets only.
- Assuming a fresh upload has no verdict: uploads deduplicate by content, so identical bytes return
the same long-lived asset id whatever the filename, and a re-upload of a file the team scored
before carries its stored verdict.
- Setting `sensitivity` on a call that returns a stored verdict: it applies to new analyses only;
stricter scoring of an already-scored asset requires `rerun: true`.
- Retrying the entitlement failure: Quality Gate is an Enterprise add-on. Degrade to the
`asset_analyze` review in `scenario-asset-analysis` and tell the user why.
