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.
