Filament v5 admin mockups — brief/spec → sign-off
Turn a product brief or spec into a set of high-fidelity, static, throwaway Filament-v5 admin mockups for stakeholder sign-off — before any Laravel/Filament code is scaffolded.
What this produces
A single self-contained HTML file that looks pixel-accurate to a real Filament v5 panel (it links the real captured theme CSS and reuses Filament's exact fi-* markup), is clickable enough to walk a stakeholder through every screen and flow, and is discarded at build time (the real Filament build regenerates all of it natively).
It IS
It is NOT
A sign-off artefact
Production code
Real Filament fi-* CSS + markup
A scaffolded Filament resource/panel
Vanilla-JS screen switching
Livewire / Alpine / a server
Data-driven by small JS arrays
Connected to a DB or API
Faithful to the brief's FRs
A place to invent new features
Why static, not a real scaffold: speed of iteration (edit one file vs re-migrate/re-seed), zero environment (opens by file://), it keeps the conversation on the spec rather than the framework, and it's throwaway by design.
When to use
Use when the user wants admin/back-end screens validated against a brief/spec before build — "Filament mockup", "admin backend mockup", "mock up the admin panel", "turn this brief into Filament screens". Prerequisite: a brief/spec with numbered functional requirements (FR-01, FR-02, …) — numbering is what makes traceability auditable. If the brief has no FR numbers, add them (or agree a numbering) first.
Do not use for production Filament code or for customer-facing/front-end mockups.
Relationship to the frontend-design skill
Do not invoke frontend-design for these mockups — for either styling or page/content planning. The two skills pull in opposite directions:
frontend-design optimises for a distinctive, memorable, non-generic aesthetic — bold typography, custom palettes, grid-breaking layouts. That is exactly what you do not want here: the value of a Filament admin mockup is maximum fidelity to Filament's existing design language (the captured fi-* theme, Albert Sans, standard resource layouts). A "creative" admin mockup misrepresents what will actually be built and undermines sign-off.
For which pages to create and the content of each page, the drivers are the FR → screen matrix (the brief) and Filament's resource archetypes (index / detail / edit / config / modal / dashboard / profile) — see Phase 2. frontend-design does not add information-architecture or admin-content-planning value.
The boundary: frontend-design is the right skill for the customer-facing / front-end mockups that sit alongside this one. This skill is for the admin back-end only. Use each on its own side of that line.
The mockup itself is thrown away at build time, but the routing table this skill writes (docs/mockups/surface-routing.md, Phase 7) is durable — it carries the substrate/producer/builder decision forward to mockup-to-filament, which reads it as its first act.
The mockup is the cheapest place to find a missing screen, a wrong field, or a flow that doesn't close. So the cardinal rule:
Every element traces to an FR. If something seems needed but isn't in the brief, flag it as a proposed requirement — don't silently add it. Invented UI that survives sign-off leaks into the spec as a phantom requirement.
Two non-negotiable conventions
The mk- namespace. Everything you add that isn't Filament (screen switcher, navigator, custom-component annotations, modal shims) is prefixed mk-. Everything fi-* is real Filament. The boundary must be visible in the source and trivial to strip.
Verify, don't eyeball. For anything subtle (spacing, whether a class is actually matching, computed styles), measure it with Playwright (scripts/verify.mjs), then delete the temp script. A clean run = no console errors + your assertions pass.
Setup (once per project)
Both bundled scripts (capture.mjs, verify.mjs) need Node and Playwright. From the project root:
npm i -D playwright # add `npm init -y` first if there's no package.json
npx playwright install chromium # downloads the browser binary (cached globally; a no-op if already present)
Notes:
Node resolves import { chromium } from 'playwright' by walking up to the nearest node_modules, so a project-local dev install works even though the scripts run from docs/mockups/reference/.
A Playwright installed into global npm also satisfies the import. A Homebrew playwright CLI does not — it's a separate binary that import 'playwright' can't resolve. If node verify.mjs throws Cannot find package 'playwright', do the project-local install above.
The browser binaries are cached per-machine (~/Library/Caches/ms-playwright on macOS), so playwright install only downloads once across all projects.
Workflow
Phase 0 — Capture the real Filament skin (once per project)
Fidelity comes from lifting the compiled theme CSS and design tokens from a real Filament v5 panel, not hand-rolling them.
Run scripts/capture.mjs against a real panel (the official demo at https://demo.filamentphp.com publishes guest credentials, or use any Filament app you control). It downloads the compiled theme stylesheet into reference/css/. Then copy into the mockup:
the theme <link> (note the Filament version in a comment — it's a dated snapshot);
the :root palette tokens (oklch variables for primary/danger/gray/info/success/warning);
the font (the demo uses Albert Sans via bunny.net).
Also screenshot the real components you'll reproduce (buttons, table, search, modals). These are your fidelity reference and your evidence when someone says "that doesn't look like Filament."
Phase 1 — Scaffold the file
Start from assets/mockup-shell.html — a working single-file scaffold containing the document shell, the mk- stylesheet, the sidebar/topbar, the bottom navigator, the "this is a mockup" banner with the indicator toggle, and the vanilla-JS controllers (mkShow, mkOpenModal, mkCloseModal, mkToggleCustom). Drop in the captured theme link + tokens from Phase 0.
Copy the body classes verbatim from a real panel (fi-body fi-panel-admin fi-body-has-navigation fi-body-has-topbar) and keep class="fi" on <html> — they activate the layout rules in the theme CSS.
Phase 2 — Inventory the screens from the FRs
Before writing markup, build an FR → screen matrix. Map each FR to the screen that satisfies it. Typical Filament archetypes: dashboard (stat + table/chart widgets), resource index (table + toolbar), resource detail/edit (form sections), config screens, action modals, empty state, profile/preferences. Anything in the brief with no home is a missing screen; any element with no FR is an oversight (flag it) or scope creep (cut it). This matrix is also your coverage checklist for Phase 6.
Phase 3 — Build screens with real fi-* grammar
Reuse Filament's exact class strings — never approximate with Tailwind. See references/fi-grammar.md for the full cheat-sheet (button taxonomy, the search-field content-ctn trap, textarea/select, table toolbar, badges, sections, sidebar+topbar alignment, dates). Each entry there is a thing that's wrong on the first try and right once you copy the real grammar.
Mark genuinely custom (Livewire-in-Filament) components — filter bars, timelines, schedule matrices, third-party-backed panels — with the dashed .mk-custom box + an FR-citing tag. Whether a piece is stock-Filament or custom-Livewire is one of the most useful things the mockup communicates, because it drives the build estimate.
Phase 4 — Wire data-driven rendering
Don't hand-write table rows. Put data in small JS arrays and render with template strings (see the example in assets/mockup-shell.html and references/fi-grammar.md). Two rules:
Reconcile the numbers. A dashboard total must equal the sum of its rows — compute it (arr.reduce(...)), don't type it. Mismatches destroy stakeholder trust.
Parameterise variant screens. If a detail screen has two states, write one entryHTML(mode) that branches, not two near-identical screens.
Phase 5 — Verify with Playwright
Use scripts/verify.mjs (copy it into the project's reference/ dir, point it at the mockup, add assertions for what you just built). Run it, confirm errors: [] and assertions pass, then delete the temp script to keep the tree clean. To diagnose why a style is off, use CDP CSS.getMatchedStylesForNode to see which theme rule is matching.
Shell cwd can reset to the repo root between calls — cd into reference/ each time and resolve the mockup with __dirname + join(__dirname,'..',…).
Phase 6 — Review loop & sign-off
Send the rendered file (single-file means the stakeholder can open it themselves). Take change requests one at a time; edit, re-verify, send back.
When told "that doesn't look like Filament," go back to the real demo, capture the exact markup/screenshot, match it — don't argue from memory.
Before declaring done, run a coverage audit: a table walking every FR and where it's represented (or why it's legitimately out of scope — e.g. customer-facing FRs in an admin mockup, or pure email/system behaviours with no static surface). This audit opens the spec and becomes the build checklist.
See references/pitfalls.md for the symptom→cause→fix table and the per-project / per-screen / pre-sign-off checklists.
Phase 7 — Write the routing handoff artifact
Emit the durable routing table so the downstream builder knows which lane owns each surface. This is the inter-skill contract introduced in spec 01 (AD3) and consumed by mockup-to-filament's Step-0 guard as its first act — so it must exist even when this skill runs alone.
Write docs/mockups/surface-routing.md with the fixed schema surface · FRs · substrate · producer · builder (a Markdown table). One row per admin surface, sourced from the Phase 2 FR→screen matrix and finalised against the Phase 6 coverage audit.
Every row this skill writes is substrate = filament, producer = filament-mockup, builder = mockup-to-filament — this skill only ever produces Filament surfaces, so the substrate/producer/builder triple is constant across its rows.
No brief-to-mockups prerequisite. On an all-Filament brief brief-to-mockups never runs, so filament-mockup is the sole producer and MUST write this artifact itself. The artifact's existence must never depend on brief-to-mockups having run first.
Merge, don't clobber. If docs/mockups/surface-routing.md already exists (a mixed brief where brief-to-mockups ran and handed off the Filament partition), add or confirm your filament rows and leave any existing bespoke rows untouched. If it doesn't exist, create it.
Why it matters. This closes the producer/consumer contract: mockup-to-filament's Step-0 guard reads the substrate column to confirm each surface is filament; naming filament-mockup as producer and mockup-to-filament as builder makes the handoff explicit and diffable, and it outlives the throwaway mockup.
