description

Validate UI evidence (a screenshot for simple cases, a video for complex flows) against the bug or plan being verified plus usage scenarios — the inverse of kitsoki-ui-demo. Picks the evidence form by complexity, extracts deterministic frames, has a read-only `claude` vision agent judge each scenario against cited frames AND whether the evidence is complete for the stated bug/plan, adversarially re-checks every pass, and emits a gated qa-report.md + verdict.json. Use when asked to QA / review / validate / sign off on a demo, walkthrough, screenshot, or bug-fix proof, or to gate one in CI.

Kitsoki UI demo QA

The inverse of [[kitsoki-ui-demo]]: that skill produces visual evidence; this one validates it. Given the bug or plan being verified, a list of usage scenarios, and the evidence (a screenshot for a simple case, a video for a complex flow — or pre-extracted frames), it decides — with cited evidence — whether the demo actually demonstrates each scenario, and exits non-zero if a required one doesn't, so it can gate a release.

Evidence is judged against the bug/plan — never in a vacuum

This skill requires the bug or plan as its --feature input (it is the spec, not just background prose). The vision review answers two questions, not one:

1. Does each scenario step appear, grounded in a cited frame? (the per-step verdict)
2. Is the evidence complete and relevant for this bug/plan? Evidence that is well-formed but doesn't actually exercise the changed behaviour — a video of an unrelated flow, a screenshot of the wrong state, a "before" that never shows the "after" the fix promises — is unsupported, even if every frame is crisp. A demo can be a perfectly good video and still be the wrong evidence.

So write the --feature file as the actual bug report or implementation plan (what changed, what the user should now see), not a generic feature blurb. The reviewer uses it to decide whether the screenshot/video proves the fix, not just whether the UI rendered.

Pick the evidence: screenshot vs video

Choose the cheapest evidence that actually proves the change, then QA that:

• Simple, single-state cases → a Playwright screenshot. If the bug/plan is fully verifiable from one (or a few) static frames — a badge label, a fixed layout, an element that should/shouldn't render, a color/spacing fix — capture a screenshot and QA it. No video needed; a screenshot is faster, smaller, and deterministic. Add a page.screenshot({ path }) to a Playwright spec driving the relevant scene (the demo helpers in tools/runstatus/tests/playwright/_helpers/demo.ts stage scenes deterministically), or reuse the NN-<scene>.png captures the recorder already emits. Drop the PNG(s) into a dir and pass --frames <dir>.
• Complex flows / multi-state transitions → a video. If proving the bug/plan needs motion — a state badge advancing turn-by-turn, a streaming bubble appearing then resolving, a modal opening on an async event, an ordering/timing behaviour — a screenshot can't show it. Record a video with [[kitsoki-ui-demo]] and QA the video (frames are extracted deterministically). When in doubt about whether one frame can carry the claim, use a video.

How to create the evidence (and keep it relevant): see [[kitsoki-ui-demo]] for the full recording pipeline (deterministic, no-LLM, MP4 + per-scene NN-<scene>.png). Whichever form you pick, it must exercise the feature being implemented or the bug being fixed — drive the specific room/intent/state the bug/plan names, not a generic onboarding tour. Evidence that doesn't touch the changed behaviour will be flagged unsupported by the review above.

This is an LLM-driven review tool by design (it needs vision). It is not a no-LLM flow test and must never be wired into the automated test suite (CLAUDE.md, [[feedback_no_llm_tests]]). It uses the local claude CLI, so — like the engine's oracle — there's no API key and no per-call cost ([[project_oracle_uses_claude_cli]]). The two deterministic stages (extract-frames.sh, report.sh) are testable on their own without any LLM.

Why it's reliable (read this first)

Video QA is unreliable when a model free-associates about UI it never saw. The pipeline removes that failure mode structurally, not by hoping the model behaves:

1. Deterministic evidence. extract-frames.sh is pure ffmpeg — scene-change detection (the meaningful moments in a UI demo are state transitions) plus a periodic floor so static dwells aren't missed. Same video + flags → same frames + same frames.json. The frames are the only admissible evidence.
2. Grounded verdicts. Every pass MUST cite a frame filename and quote what is literally visible. A claim with no citable frame is unsupported (never silently pass); a frame that contradicts it is fail.
3. Adversarial re-check (interpretive ÷ deterministic). A second claude pass plays skeptic: it re-reads each pass step's cited frame and emits only a small list of downgrades (which step, to fail/unsupported, and what the frame really shows). qa-review.sh then applies them deterministically — it can only lower a status, never raise one (the downgrade-only invariant is enforced in code, not by trusting the model), and recomputes every scenario/overall/summary itself. The tiny delta output (vs. re-emitting the whole multi-KB verdict) is what makes this pass robust. Model output is parsed with a brace-matching JSON extractor that tolerates stray prose / ``` fences. The result is recorded as adversary: {status, downgrades_applied} on the verdict. (--no-adversary to skip.)
4. Authoritative gate. report.sh recomputes pass/fail from the per-scenario status in verdict.json (it does not trust the model's own overall) and sets the exit code. Under --strict it additionally blocks if the adversarial pass was supposed to run but did not complete (adversary.status != "ok"), so a silent adversary flake can never pass a strict gate.
5. Visual-integrity check. A demo can render a feature's frame as a large blank/uniform box (an all-white screenshot pane, a broken-image glyph, an empty preview) and still "show the right region." The review prompt treats a blank where visual content is expected as fail (not pass), the adversary specifically re-checks visual pass steps against their frame, and any visual_issues[] the model reports (proactively, even when no scenario names the region) block the gate at every effort level — surfaced in a "Visual issues" table in qa-report.md. Backing this is a deterministic layer: blank-scan.sh (pure ffmpeg + python, no LLM) flags any frame with a large contiguous flat block of a single colour — any colour, not just white/black, excluding the page background — or a near-empty frame. It runs on every qa.sh invocation; flags are advisory (a flat block can be a legit empty panel) unless --blank-strict. Together they stop a silently-broken image from passing QA — the LLM catches context, the scan catches what a model might gloss over. For rrweb-backed Slidey decks, do not stop at producer metadata (rrweb markers, chapter events, style signatures). Add or run a replay-pixel gate that opens the actual captured rrweb logs, seeks to the relevant moments, and checks what the deck viewer will render. This is how color/source-surface bugs and label-only readable zooms get caught; helper-only screenshots are a unit test, not evidence sign-off for the deck.
6. Annotation-consistency check. A demo must narrate with ONE mechanism throughout — either tour popovers (a titled card with a "Step N of M" counter and Back/Next/Skip, anchored to a spotlight ring) or banner/caption overlays (a flat title+subtitle strip, no Next affordance). Both styles are legitimate on their own; the invariant is CONSISTENCY, not "must be tour". A single video that MIXES the two — a tour-popover intro that then hands off to banner captions for the feature payload — is the defect (it reads as two demos stitched together, and a scenario set written to bless the captions will never flag it). The review prompt (EVIDENCE RULE 6) classifies the narration style in every frame and, if BOTH styles appear across the video, emits a top-level annotation_issues[] ({frame, styles_seen, issue}); a single consistent style → empty array. Any annotation_issues block the gate at every effort level (same treatment as visual_issues) and are surfaced in an "Annotation issues" table in qa-report.md. A required annotation-consistent scenario in the scenario file pins the expectation in the per-step verdict as well.
7. Pacing check (deterministic, no LLM). A demo is only good if each narrated moment stays on screen long enough to read — and the vision pass is blind to this: every individual frame still looks correct, so a tour where every popover flashes by in 70ms passes clean (the classic footgun: recording with WEB_CHAT_PACE=0, the fast-validation posture, collapses every dwell(step.dwellMs) to ~0, yielding a 12-second blur instead of a readable ~80-second walk). pacing-scan.sh (pure jq) reads the recorder's chapter sidecar (<video>.chapters.json, emitted by ChapterRecorder/writeChapters — see [[kitsoki-ui-demo]]), where each tour step carries the [start_ms,end_ms] window it actually occupied in the final MP4, and flags any chapter whose duration is below the readable floor (--pacing-min, default 1500ms; also a total-span floor). Same video in → same flags out. qa.sh auto-detects the sidecar beside the MP4 and runs it on every invocation; flags are advisory (surfaced in a "Pacing warnings" table, never block) unless --pacing-strict, which promotes them to a blocking gate — the same advisory/strict shape as blank-scan. This is the deterministic catch for "the pacing is terrible" that no amount of frame-by-frame vision review can see. 7b. Embedded-rrweb pacing check (deterministic, no LLM). A tour can be embedded as a native rrweb clip (a slidey video scene replaying a .rrweb.json log) rather than an MP4 — and then BOTH prior pacing defenses are blind: there is no chapter sidecar for pacing-scan.sh to read, and the frame sampler sees each end-state frame looking correct. The defect this misses: a captured conversation plays fine for most of its length, then the last few messages / the final artifact all flush in under a second — "the last 3-5 messages are super-rushed." That is invisible to interpretation; it lives only in the rrweb event timeline. rrweb-pacing-scan.mjs (pure structural parse, no LLM, no ffmpeg) reads the clip directly: a content reveal is an incremental DOM mutation whose adds introduce a substantial block (clears --sig-min-adds / --sig-min-text); reveals within --coalesce ms are one logical render; each reveal must hold for --min-dwell ms (default 1200) before the next, and a burst inside the final --tail-window ms is reported as the rushed tail. Pass --rrweb <clip.rrweb.json | dir> to qa.sh; flags are advisory (a "rrweb-pacing warnings" table) unless --rrweb-strict promotes them to a blocking gate — same advisory/strict shape as blank-scan/pacing-scan. The fix when it fires: give the capture an end-of-conversation dwell, or re-pace the clip deterministically with slidey rrweb-repace <in> <out> (which mirrors this scan's significance definition, so a re-paced clip clears the gate). 7c. Embedded-rrweb scroll-followability check (deterministic, no LLM). The rrweb-pacing scan (7b) measures the TIME between content reveals and is structurally blind to SCROLL. A captured conversation can space its reveals a comfortable 2.8s apart and still be unwatchable: ChatTranscript.vue snaps the scroller to the BOTTOM on every new message, so a reply taller than the fold (or the user input that triggered it) renders already scrolled off-camera. The pacing scan green-lights it (the reveals ARE well-spaced); the viewer can read none of it — the #1 recurring "you can't see the user inputs / it's jumpy" defect. rrweb logs don't serialize node geometry, so the structural signal is the scroll-event stream: rrweb-scroll-scan.mjs (pure parse, no LLM) classifies each scroller node's runs into SNAP jumps (an instant scrollTop = scrollHeight reposition — a large downward entry jump that is not a dense easing burst) vs EASED reveal runs (a revealTurn-style requestAnimationFrame burst, ≥6 events over ≥600ms, the followable choreography). A clip is flagged unfollowable when a scroller is snap-dominated (snap_runs ≥ --min-snaps AND snap_runs > eased_runs). Calibration (this repo): the live dogfood captures show 3–13 snaps / 0–1 eased; the revealTurn-driven gears-bugfix capture shows 14 eased / 1 snap. Pass --rrweb <clip|dir> to qa.sh (same input as 7b); flags are advisory (a "Scroll-followability warnings" table) unless --scroll-strict promotes them to a blocking gate — same advisory/strict shape as the other scans. The fix when it fires: re-render the clip through the conversation reveal track (revealTurn at capture, or slidey rrweb-reveal), never a time-only re-pace — adding time to a snapped capture just holds the bottom of each message longer; the top still never shows.
8. Stuck-placeholder check. A panel can sit on a transient placeholder forever — a "Loading…" spinner whose loading flag is never lowered — and every single frame of it still looks "fine," so blank-scan (mostly themed bg) and a frame-at-a-time reviewer both miss it. The review prompt now reads the frames as a timeline and fails a panel whose placeholder persists across many frames (rule 7), and a deterministic placeholder-scan.sh (OCR) flags a placeholder that runs unbroken for --min-run frames or covers --min-fraction of the demo. This is what catches "the three panels just say Loading… for a long time."
9. Conversation-legibility + occlusion check. A demo of human usage must let a viewer FOLLOW the conversation. The review prompt (rules 7–8) reads the frames as a timeline and emits a blocking visual_issues[] entry when: an operator INPUT is never visible as legible text (it flashed by / was sent off-camera); an agent RESPONSE is clipped to nothing or never shown (long replies MAY truncate); a long RESPONSE is only ever shown scrolled to its bottom so its opening lines never appear (the transcript snapped to the end instead of scrolling THROUGH the message — the #1 "jumpy" cause); a raw internal intent name with double underscores (core__prd__start) is visible as a label (stale embed / un-humanised surface); the chat transcript is covered or pushed off-screen by another panel (a file/PRD/diff editor opening OVER the conversation); or a floating overlay (tour coachmark / popover / tooltip) overlaps and obscures the chat. This is what catches "the video is jumpy, you can't see the user inputs, and the editor hides the chat." Because visual_issues always block the gate, such a demo can never pass — author it so each message SCROLLS THROUGH (use the revealTurn helper, never fixed dwells over the native auto-scroll), the chat stays visible beside the editor, labels are humanised, and every input is readable (see kitsoki-ui-demo).
10. Right-surface + progress-legibility check. A demo of a feature used by a human must prove it on the product's conversation surface — and every conversation must provide meaningful feedback as it progresses, even when no operator input is required. An autonomous / self-driving run (one that advances with no human turn — e.g. a loop that cascades to terminal on entry) must still narrate each step as readable conversation messages, not advance silently. The footgun this catches: a demo that shows the run ONLY through the developer-facing trace/observer (the state diagram + an event timeline of host.run / world.update / machine.say rows) while the conversation pane stays empty. The auditor's trace is not the product experience; proving "the feature works" on the trace alone is the WRONG SURFACE. The review prompt (EVIDENCE RULE 9) reads the frames as a timeline and, when the feature/scenarios describe usage/a-loop/a-conversation but only the trace ever appears, emits a blocking visual_issues entry and fails every usage scenario. The one exception is a feature that genuinely is the trace/observer/diagram (the run viewer itself) — there the trace is the correct surface, decided from the feature file, not a default. (Runtime side: a self-driving kitsoki run surfaces its say: breadcrumbs as conversation bubbles so this feedback exists to film — see the demo-video-loop story.)
11. Interaction-affordance completeness. A multi-step UI flow is not proven by its final state alone. If the feature or scenarios require an intermediate user-visible affordance — a context menu, dropdown, popover, command palette, confirmation sheet, chooser, inline editor, placement marker, or similar surface — at least one cited frame must show that affordance before the final result. A direct jump from the trigger to the final modal/page/state is incomplete evidence and must be unsupported or fail depending on whether the frames merely omit or actively contradict the required intermediate UI.

Prerequisites

ffmpeg, jq, and the claude CLI on PATH (all already present in this repo's dev env). No make build needed — this consumes an existing video/frames.

The loop

1. Give it the bug/plan + what the evidence should show. Copy the templates and edit — --feature is the actual bug report or implementation plan, not a generic blurb (see "judged against the bug/plan" above):

   D=.agents/skills/kitsoki-ui-qa
   cp $D/templates/feature.example.md   .context/qa-feature.md   # ← the bug or plan
   cp $D/templates/scenarios.example.yaml .context/qa-scenarios.yaml
   

   Scenarios are observable claims ("the state badge advances", "three story cards are listed") — not internal behaviour the camera can't see. Mark a scenario required: false to keep it non-blocking.

   Then pick the evidence form (see "Pick the evidence" above): a screenshot for a simple, single-state case; a video for a complex/multi-state flow.

2. Run the QA gate (one shot: extract → contact sheet → review → report). For a screenshot (or any pre-captured PNG set), pass the frames dir directly — the positional path is only used to name the output dir:

   .agents/skills/kitsoki-ui-qa/scripts/qa.sh .artifacts/fix-badge/badge.png \
     --frames   .artifacts/fix-badge \
     --feature   .context/qa-feature.md \
     --scenarios .context/qa-scenarios.yaml --strict
   

   For a video:

   .agents/skills/kitsoki-ui-qa/scripts/qa.sh \
     .artifacts/multi-story/multi-story.mp4 \
     --feature   .context/qa-feature.md \
     --scenarios .context/qa-scenarios.yaml
   echo "gate exit: $?"          # 0 pass · 1 blocking failure · 2 pipeline error
   

   Artifacts land in .artifacts/ui-qa/<video-stem>/ ([[feedback_artifacts_dir]]): frames/, frames.json, contact-sheet.png, verdict.json, qa-report.md.

3. Prefer ground-truth frames when you have them. The recorder already emits labeled per-scene NN-<scene>.png. Point --frames at that dir to QA those exact captures instead of re-extracting (highest fidelity, skips ffmpeg):

   .agents/skills/kitsoki-ui-qa/scripts/qa.sh .artifacts/multi-story/multi-story.mp4 \
     --frames .artifacts/multi-story --feature .context/qa-feature.md \
     --scenarios .context/qa-scenarios.yaml --strict
   

4. Read qa-report.md. Per-scenario table with the cited evidence frame for each step. Open the cited PNGs (or contact-sheet.png) to confirm. If a scenario is unsupported, the demo didn't cover it — usually a gap in the demo, occasionally a vague scenario step to sharpen.

Full-editor (VS Code) evidence

QA'ing a full-editor video (the kitsoki UI embedded in a VS Code window — see [[kitsoki-ui-demo]] → "Full-editor (VS Code) mode") differs from a browser video: a larger 1400×900 frame, a big dark editor pane / empty welcome region, and VS Code chrome (Activity Bar, panels) with grey edge strips. Two deterministic stages need the right invocation so the gate stays trustworthy:

• Prefer the labeled ground-truth frames the recorder emits (.artifacts/vscode-tour/NN-<beat>.png, one per beat). Pass them via --frames — highest fidelity, no scene-extraction artifacts, and they pass blank-scan.sh at the default --min-coverage 0.10 (proven: 0 flags on the 7 vscode-tour beats). This is the recommended path.

  docs/skills/kitsoki-ui-qa/scripts/qa.sh \
    .artifacts/vscode-tour/vscode-tour.mp4 \
    --frames    .artifacts/vscode-tour \
    --feature   .context/qa-vscode-feature.md \
    --scenarios .context/qa-vscode-scenarios.yaml --strict
  # → overall: pass, 6/6 scenarios, 0 visual issues, 0 blank-scan flags
  

• If you must scene-extract (no labeled frames), extract-frames.sh at the default --scene 0.30 surfaces the editor's meaningful transitions fine (≈18 frames on the 72s vscode-tour). But the full-window frames carry a legitimate grey editor-chrome edge strip (~12.5% of the frame) that trips blank-scan.sh at the default --min-coverage 0.10 as a false "solid block". Raise the threshold for editor videos via the qa.sh passthrough:

  docs/skills/kitsoki-ui-qa/scripts/qa.sh \
    .artifacts/vscode-tour/vscode-tour.mp4 \
    --feature .context/qa-vscode-feature.md \
    --scenarios .context/qa-vscode-scenarios.yaml \
    --blank-min-coverage 0.15        # editor-chrome strips no longer false-flag
  # → blank-scan: 0 flags on the 18 extracted frames
  

  --scene TH is also a passthrough if you want denser/sparser extraction.

The legitimately dark editor pane / empty welcome region does not false-flag at any setting: blank-scan.sh's contrast gate treats the most-common dark bucket as the page background, so a large dark region is correctly ignored (only a high-contrast solid block flags). The grey edge strip was the only editor-specific false positive, and --blank-min-coverage 0.15 clears it while still catching a genuine blank pane.

A ready-to-edit feature/scenarios pair for a VS Code embed lives at templates/vscode-feature.md + templates/vscode-scenarios.yaml (the worked example behind the vscode-tour gate above).

rrweb-embedded slidey composite deck evidence

A new reusable deliverable shape: a slidey composite deck — section/title slides + chapters authored in slidey, with one or more embedded act windows that play a captured rrweb clip of a kitsoki surface (seek-rasterized into the deck during render). QA the rendered deck MP4 exactly like any other demo video — the gate is unchanged — but mind these composite-specific points:

• Sample at ≥2fps (qa.sh ... --scene denser, or hand extract-frames.sh --interval 0.5). The embedded act scenes are rrweb seek-rasterized, so the deck holds a frame and steps it; a ≤1fps sample can land between rasterized steps and miss the legible window of an act window (same rule the demo skill pins for replay videos). Title/section slides are static and forgiving, but the embedded windows need the higher floor.
• Each embedded act window must be non-blank. The #1 composite failure is an act window that renders as an empty/uniform pane (the rrweb clip failed to load or seek, leaving the embed slot blank) while the surrounding deck chrome looks perfect. Treat a blank where an act surface is expected as fail — author a scenario step per act window asserting its real content is visible, and lean on blank-scan.sh (advisory; promote with --blank-strict for a deck where the act windows are the whole point). A deck-frame background or letterbox bars around the embed are legit (background buckets are ignored by the scan); a flat block inside the act slot is the defect.
• Section/title slides + chapters must be present. Write scenarios asserting the deck's title slide, each section/divider slide, and that chapter boundaries exist (the deck MP4 should carry a <video>.chapters.json sidecar — pacing-scan.sh auto-runs over it; a composite missing its chapters or with a flashed-by act window will surface as a pacing flag).
• Capture mechanism is invisible to QA. An adapter-captured clip (an app driving slidey's tour engine through its own ADAPTER — e.g. tools/runstatus/src/tour/kitsoki-tour-adapter.cjs + act2-webviewer.tour.json, whose output is act2-webviewer.rrweb.json) is QA'd identically to a harness-captured one. Do not special-case it, do not assert on adapter/capture internals — QA judges the rendered pixels of the deck MP4 against the scenarios, full stop. The same blank/pacing/legibility gates apply regardless of how the clip was produced.

The LLM visual_issues and annotation_issues checks (context-aware) always block regardless.

Pointers

• The recorder this inverts: [[kitsoki-ui-demo]] (.agents/skills/kitsoki-ui-demo/) — its NN-<scene>.png output is the ideal --frames input here, and its contact-sheet.sh is reused for the storyboard.
• Oracle = local claude CLI: internal/host/oracle_runner.go.
