Produce an adversarially-verified, source-cited, full-stack, interactive HTML decision brief for informed go/no-go sign-off at a human decision boundary. MVP mode: pivot-review. Extends /ux-design; consumes /research and /design; feeds /design on GO.
Purpose: Render a proposed change as an adversarially-verified, source-cited, self-contained interactive HTML decision brief — a "wireframe on steroids" — so a human can understand and sign off on the direction before expensive, hard-to-reverse work begins. This is a communication + decision gate, not a production step. It extends/ux-design (frontend-only markdown Design Brief → full-stack interactive HTML), consumes/research and /design, and feeds/design on a GO.
MVP scope: only the pivot-review mode is implemented. The honesty spine — ≥3 diverse adversarial lenses, fetch-and-field-match source verification, a structural self-check, and disk-save durability — is non-negotiable.
Pre-flight Check
This skill is not standalone — it synthesizes upstream artifacts. Before proceeding:
Confirm a Findings Tracker exists: Glob docs/findings/*_FINDINGS_TRACKER.md. If none, STOP: "Run /finding first to create a Findings Tracker." (--force bypasses.)
Confirm at least one artifact describing the proposed change exists — a /design doc (docs/design/*.md), else a /research doc (docs/research/*.md), else the finding report itself. If none of these describe the change, STOP and ask the user to point at the change source.
In-flight major/irreversible change → as-is vs to-be → GO/NO-GO, before designing the pivot.

Step 1: Scope & Inputs (Phase 0)
Name the decision the brief must support, and the audience (dev / owner / stakeholder).
Gather inputs: the findings tracker, /research and /design docs, ARCHITECTURE.md, the codebase (for the verified as-is), and any prior briefs in docs/design-briefs/.
CST-005 trigger determination (this drives Step 8's Decision-Requested content): ask "Is the briefed decision irreversible AND public?" — a SemVer-permanent surface, relicensing, a trademark class, or public launch copy. Default yes when unsure. If yes, set the irreversible+public tag: the Decision-Requested section MUST carry the CST-005 human-spine clause (Step 8). If no, the CST-005 clause is N/A for this brief. The human owns this call — a model self-assessing the trigger shares the blind spot it hedges.
Change-type determination (this drives which mockup sections Step 5 renders): decide the change-type — decision-only (the default; a pure go/no-go brief like the shipped S119/S125 — renders neither mockup container), front-end, back-end, or full-stack. A front-end or full-stack change emits the §4 front-end mockup container (id="mockups"); a back-end or full-stack change emits the §5 back-end mockup container (id="backendmockup"). A decision-only brief emits neither and stays exactly as today.
Step 2: Ground — thinned (Phase 1)
Fan out the verification core as parallelAgent spawns. CRITICAL: launch all ground agents in a SINGLE message using the Agent tool (true parallel execution). For each: subagent_type: "general-purpose", a per-spawn model, and a prompt instructing structured returns. Thin the front/back split to the change-type (Step 1): a front-end change thins the back-end agent, a back-end change thins the front-end agent, full-stack ⇒ thin NEITHER, decision-only ⇒ thin BOTH mockup agents:
Agent G1 — evidence & citations (model: opus): consolidate every load-bearing claim; for each source, capture title/authors/date/venue/URL for the Step-6 fetch-and-field-match pass.
Agent G2 — as-is (model: opus): extract the verified current state from the codebase; cite file paths.
Agent G3 — to-be + change-map (model: opus): extract the proposed design and the EXACT change map from the design/research artifact. When the change-type touches back-end, also emit the back-end mockup specs — architecture nodes/edges, ERD entities/relations, API/contract endpoints, and sequence (control+data flow) steps — for the §5 id="backendmockup" container.
Agent G4 — front-end mockup specs (model: opus, only when the change-type touches front-end): emit UX-flow, screen-wireframe, and component-inventory specs, and consume /ux-design's design-system markdown (tokens/type/color/motion) for the §4 id="mockups" container. Fable stays holstered (CST-004).
Each spawn returns structured findings and returns ONLY those findings. Do NOT include any "read/update your MEMORY.md" instruction — these inline spawns have no agent-file memory scope (nothing to read or write).
Step 3: Adversarial — KEPT (Phase 2)
Barrier: this needs ALL of Step 2. Spawn exactly three diverse lenses as inline prompts (no agent files), one lens per spawn, in a SINGLE message. Heterogeneous per-spawn model pins give same-lab partial decorrelation:
honesty-hawk (model: opus) — hunt every overclaim; force the honest noun; reject hype.
cost-skeptic (model: opus) — attack the numbers, baselines, and cherry-picks; demand the risk case first.
mechanism-skeptic (model: opus) — attack every technical assertion stated as fact; flag the unverified.
Each inline lens prompt MUST embed this Discipline block verbatim:
Objections, never verdicts. Never write "approve", "reject", "PASS", "looks good", a score, or a recommendation. Return a list of things the author must confront.
Tier every objection: MUST-ADDRESS (a gap that could flip or badly damage the brief) · SHOULD-CONSIDER (a real omission worth a sentence) · NOTE (minor / for-the-record).
Ground each objection in a specific artifact reference.
No consensus, no aggregation. One independent lens per spawn; divergence is a feature.
Close every non-empty response with the fixed caveat line: Caveat: same-lab critic — catches skipped omissions only; does NOT decorrelate shared blind spots (that is the Layer-0 human + Layer-3 cross-lab hedge's job).
Fable stays holstered (CST-004) — never a grader/verifier/judge here; use only model: opus for the lenses (the F4 floor; Fable never). Collect the independent tiered objections — never a consensus vote, never a score.
Step 4: Synthesize (Phase 3)
Barrier: this needs ALL of Step 3. Merge the ground content and APPLY every valid adversarial correction into ONE master content brief: all sections + chart data series + diagram specs + walkthrough content + glossary + the Decision-Requested content. Every load-bearing claim must carry its evidence AND its honest ceiling.
Step 5: Render (Phase 4)
Load the artifact-design skill FIRST for design-craft guidance before writing any HTML.
Build the self-contained, CSP-safe interactive HTML from skills/design-brief/design_brief_template.md. Author it in Artifact-compatible form: inline <style> and <script>, embedded/hand-built SVG, no<!doctype>/<html>/<head>/<body> wrapper (the Artifact tool adds the skeleton; browsers render the wrapper-less file from disk).
Required interactive/robustness properties: both themes (:root light default + @media (prefers-color-scheme:dark) + :root[data-theme="light"]/["dark"] overrides); the as-is⇄to-be toggle (id="vAsis"/id="vTobe"/aria-pressed/data-view on the body); provenance chips; confidence-tiered references; the Decision-Requested block; the glossary; :focus-visible; @media (prefers-reduced-motion:reduce); no horizontal body scroll (wrap wide content in an overflow-x:auto container such as class="tablewrap").
Conditional accessibility upgrade: IF you emit a role="tablist" stepper, it MUST carry a keydown arrow-key roving-tabindex handler (ArrowUp/ArrowDown/ArrowLeft/ArrowRight). If no tablist is present, this is N/A.
Full-stack mockup render (only when the change-type is front-end / back-end / full-stack) — a two-medium contract inside this same CSP-safe envelope (no new render channel; a live-JS diagram lib such as Mermaid is a non-starter — CST-006):
Back-end structure (§5 container id="backendmockup"): hand-built static inline SVG with live var() theming — C4/architecture (id="architecture"), ERD data model (id="erd"), API/contract surface (id="apisurface"), and sequence / control+data flow (id="dataflow"). Each <svg> carries role="img" + aria-label, a viewBox, and width:100%;height:auto (fluid, no horizontal body scroll). Prefer static var()-SVG over JS-built SVG (theme-aware for free).
Front-end design (§4 container id="mockups"): render UX flows (id="uxflow"), screen wireframes (id="wireframe"), the design system (id="designsystem", consumed from /ux-design), and a component inventory (id="componentinv") as HTML/CSS on the proven .card/.grid system (text-dense UI reflows better than baked SVG text). Map the as-is⇄to-be toggle onto current-UI vs proposed-UI.
Anti-slop (mandatory for front-end mockups): after artifact-design, load the frontend-design skill and run its ASCII-plan → critique-against-generic-defaults → build loop, plus /ux-design's anti_patterns.md checklist, so the wireframes do not read as generic AI defaults.
Honesty (structure-only): the lint verifies these anchor ids are present, NOT that a mockup is accurate or complete. A dimension with no change may honestly state "no change" — never fabricate a diagram. Pitch mockups as ambiguity-reduction / shared-understanding at a decision boundary, not a discredited fix-early 100×/13× multiplier.
Step 6: Verify Sources — sharpened (Phase 5)
For every citation, run fetch-and-field-match (plausibility and id-resolves checks are insufficient — 2026 fabrications weaponize semantic plausibility and hijacked identifiers):
Extract the claimed fields (title, authors, year, venue, URL).
WebFetch the source.
Field-match the fetched content against the claimed fields.
Judge and assign a confidence tier: verified (real URL, fields match) · prior art · attributed post-hoc · official / vendor.
quarantine-on-no-fetch: if a source cannot be fetched, tag it explicitly as unverified/reported — never fabricate a citation to fill a gap, and name which sources cannot be named.
Step 7: Structural Self-Check
Grep the generated .html for the hard-invariant anchors. If any is absent, fix the render before publishing. (Anchors are the S119-verified literals.)
Provenance / confidence (the honesty spine):chip emp, chip est, chip rep; chip hi, chip med, chip low; the tier labels verified, prior art, attributed post-hoc.
Decision block:id="decision", class="riskgrid", Risk of YES, Risk of NO, class="verdict, Recommended:.
Conditional — tablist: IF the brief contains a role="tablist" stepper, it MUST also contain a keydown arrow-key handler; if no tablist, N/A (not a failure).
Conditional — front-end mockups: IF the brief communicates a front-end design (contains id="mockups"), it MUST also contain id="uxflow", id="wireframe", id="designsystem", and id="componentinv"; if no mockups container, N/A (not a failure).
Conditional — back-end mockups: IF the brief communicates a back-end design (contains id="backendmockup"), it MUST also contain id="architecture", id="erd", id="apisurface", and id="dataflow"; if no back-end mockup container, N/A (not a failure).
Soft anchors (warn only, vary per brief): specific numbered-section ids, exact reference counts.
Step 8: Publish & Save (Phase 6)
Disk-save is the durable, REQUIRED path; Artifact-publish is best-effort.
ALWAYS first save the HTML to docs/design-briefs/{YYYY-MM-DD_HHMM}_{decision}.html (this saved file is what Step 7 self-checks). Create docs/design-briefs/ if it does not exist.
The Decision-Requested block content depends on the Step-1 tag. If the irreversible+public tag is set, the block MUST surface the CST-005 human-spine obligations: a prompted cooling-off, a lawyer / TM-attorney review for relicensing / trademark-class triggers, and the explicit caveat that this brief is NOT the decorrelation hedge — a same-lab LLM pass does not decorrelate shared blind spots.
THEN attempt to publish the same saved file via the host Artifact tool (title, one-sentence description, favicon). The Artifact tool is a claude.ai-login capability and MAY be absent in a plain terminal session (it is not in allowed-tools). If available: publish and report the URL. If unavailable or it errors: DO NOT fail — report the saved path and tell the user to open the self-contained .html in a browser. The skill SUCCEEDS on the saved file alone.
Step 9: Findings Tracker Update & Handoff
Update the Findings Tracker if this was invoked as part of a tracked workflow. See tracker_update_checklist.md.
CRITICAL PIPELINE RULE: Suggest ONLY the next pipeline step below. Do NOT offer to implement. Do NOT offer to skip steps.
Next step: this brief is a GO/NO-GO gate. On GO, run /design to design the pivot.
On NO-GO, revisit the finding.
Awaiting your instructions.
STOP — do NOT proceed with implementation. Do NOT add commentary suggesting any pipeline step could be skipped or is unnecessary. Wait for the user to decide how to proceed.
