spacing-1..5 = 4/8/12/16/24 px — a 4-point base scale covering xs through xl.
All tokens use type="number" with plain scalar values. Palette total grows to 57.
type-display-letter-spacing (-0.5 px) for large display text, and
type-uppercase-label-letter-spacing (1.5 px) for uppercase / overline labels.
Palette total grows to 52.
size + weight + line-height for 6 roles: display / h1 / h2 / h3 / body / caption.
All 18 tokens use type="number" with a plain scalar value (no theme axis).
getSemanticPaletteHex() omits numeric tokens from its return map.
Palette grows from 32 color → 50 total variables.
8 light/dark alert pairs (info/success/warning/danger bg+text) and 6
single-value chart series colors added to PALETTE. PaletteEntry union
type introduced to support LightDarkEntry | SingleColorEntry | SingleNumberEntry.
getSemanticPalette(), getSemanticPaletteHex(), applySemanticPalette()
updated to handle all three entry shapes. Palette grows from 14 → 28 tokens.
Sweep follow-up to 113bd55a — same defensive pattern (reject
unknown enum strings at the entry boundary) applied to every other
builder that indexed a Record<EnumLiteral, T> with a value sourced
from raw JSON args.
Builders + enums covered:
- buildTag — TagTone (default | accent | success | warning | error)
- buildCallout — CalloutTone (info | success | warning | danger | note)
- buildActivityLog — tone (info | success | warning | danger | neutral)
- buildInviteRow — InviteStatus (pending | expired | accepted)
- buildMemberRow — trailing.tone for status_dot (online | busy | away
| offline). role_badge / menu variants skip the check (no tone field)
Same failure mode each one fixed: when a model invents an
out-of-enum string (gpt-5.4 did this with `level: "caption"` in
ab-v4), the lookup `TONES[bad]` / `STATUS_TONE[bad]` returned
undefined, the next property access crashed mid-batch with a
cryptic `undefined is not an object`, and the surrounding dispatch
loop dropped every remaining tag (until df33e937 + 07639f6d landed
the per-shape continuation + partial-doc scoring earlier today).
With validation in place, a bad enum becomes a clean per-shape
error message + the rest of the batch still applies.
13 new edge-case tests cover throw on bad input + valid path on
every enum value + omitted-default for each builder. 3785 vitest
pass, format clean, tsc silent.
Builders not touched: heading.ts (already done in 113bd55a).
Builders that don't fit this pattern (no enum→Record lookup of a
user-controlled string): everything else surveyed via grep on
`Record<.*Tone|Status|Level|Mode|Kind`.
ab-v4 partial sweep (2026-05-01) caught gpt-5.4 emitting
`add_heading_v0({"content":"Pending invitations","level":"caption"})`
as the 12th tag of a 13-tag composite multi-tool response. Even
though the MCP tool def has `enum: ['display','h1','h2','h3']`, the
ab-corpus harness and the in-process production dispatcher both call
buildHeading() with raw JSON args (no jsonschema gate), so the model's
invented "caption" reached the preset lookup. LATIN_PRESETS["caption"]
is undefined, and the next line `fontSize: preset.fontSize` crashed
the WHOLE batch with `undefined is not an object (evaluating
'preset.fontSize')` — the 11 valid tags ahead of it never landed.
Adds an entry-point validation in buildHeading: if `level` is set and
not in the {display, h1, h2, h3} set, throw with a clear message.
The dispatch loops in apps/web/element-tools-dispatcher and
scripts/ab-corpus/apply both catch per-shape and keep running the
remaining tags, so a single bad level on tag 12 no longer kills tags
1-11 + 13.
3 new edge-case tests in element-builders-edge-cases.test.ts
cover the throw + the four valid levels + the omitted-default case.
3772 vitest pass (+3), format clean, tsc silent.
Other element builders likely have the same pattern (preset lookup
on a string enum without runtime validation) — separate sweep, not
shotgunning here.
The previous schema description and JSDoc invited "Step 1" as a valid
value for `number`, but that prose has 6 chars and overflows the 36px
circle marker. Two changes:
- Builder: add clipContent: true on the marker frame so any caller
who ignores the docs at least gets a clipped (not bleeding) render.
- Schema + JSDoc: drop the misleading "Step 1" example, document the
1–3 character contract, and steer prose toward `title` instead.
Closes the obvious gaps remaining in the family:
- add_filter_group_v0 — sidebar facet (heading + checkbox-style options
with optional counts). Distinct from nav_chip_row (horizontal scrolling
chips), tag (single applied chip), segmented_control (mutex tabs).
- add_invite_row_v0 — pending invite row (avatar + email/role + status
pill + trailing action). Distinct from member_row (a JOINED member,
no status pill or action) and list_row (no avatar / status / action).
- add_activity_log_v0 — single-line audit feed entry (optional tinted
icon dot + actor in bold + action + right-aligned timestamp). Uses
StyledTextSegment[] content for the bold/regular split. Distinct from
timeline (multi-event vertical with connectors) and notification_row
(title + body, no actor focus).
- add_event_card_v0 — single calendar event tile (date column with
month band + day number, then title + time + location). Distinct from
calendar_grid (the full month grid) and card_row (no date column).
- add_step_card_v0 — onboarding step card (numbered circle / check +
title + description). Distinct from stepper (horizontal progress nav
with connectors) and faq_item (collapsible Q&A header).
9 touchpoints per tool: pen-core builder + index + barrel + types,
pen-mcp handler + dispatcher + ext-4 schema, apps/web shim +
SERVER_BUILDERS, parity test (+5 cases), elements.md decision tree
items 86-89 + 6 PREFER mappings with cross-links to existing tools,
elements-cookbook.md arg-shape examples (8 entries across 5 tools).
Leading icon + (title over optional subtitle) + trailing control with
4 variants: chevron / value text / switch / badge. Distinct from
add_list_row_v0 (trailing is always icon, no switch/value/badge) and
add_form_field_v0 (label-above-input for forms).
Wires all 9 touchpoints: pen-core builder + index + barrel re-export,
pen-mcp handler + dispatcher case + ext-4 schema, apps/web shim +
Nitro SERVER_BUILDERS, elements.md decision tree #83 + PREFER mapping,
elements-cookbook arg-shape examples, plus shim-server parity case.
Adds the desktop-leaning batch needed to round the family to 90:
- add_user_card_v0 — compact avatar+name+role row
- add_drawer_shell_v0 — full-height side panel header
- add_combobox_v0 — open-state autocomplete with dropdown
- add_toolbar_v0 — desktop icon button row + dividers
- add_callout_v0 — inline doc tip block, 5 tones
- add_share_row_v0 — circular social-share buttons
- add_inline_action_v0 — message + Undo-style action
- add_legend_item_v0 — chart legend marker+label+value
- add_inbox_message_v0 — email/inbox row with unread dot
- add_profile_header_v0 — large profile hero block
All ten go through the standard 9-touchpoint wiring and land in a
new ext-4 schema shard so existing shards stay under 800 lines.
Drift guards (contract / registry parity / shim-server parity) cover
each new name; per-tool handler tests are deferred — every tool's
structure is exercised through the parity build call already.
Long cell content rode `width=auto` and the cell itself had
`height=fit_content` with no clip, so a string longer than its
allotted column would push past the cell edge into the adjacent
column at render time. Switch each cell to `width/height=
fill_container + clipContent=true`, give the text child
`width=fill_container + textGrowth=fixed-width` so the layout
engine wraps inside the cell, and clip the row itself so a runaway
cell can't push siblings off-row either. Lock the contract in the
handler test.
Greps every builder source for paddingTop/Right/Bottom/Left as a
property key and fails if any reappear. The unified padding field is
the only form resolvePadding reads; the CSS-side siblings render with
zero inset, which slipped past type checks because ElementTree is
Record<string, unknown>. JSDoc / line-comment mentions stay allowed
so builders can still document the trap inline.
origin's v0.8.0 had cherry-picks of the v0.7.5 deepseek/image-search
fixes (a727632a, a5952bc8) overlapping local 2073cf5b / 04f4fbc1, plus
new commits (model-selector ark-coding deepseek-v4-pro/flash IDs that
ARK rejects, fetch error.cause unwrap, CI agent-native build, op
export docs cleanup, main merge). Resolved the ark-coding list in
favor of HEAD's deepseek-v3.2 entry (only model ARK Coding Plan
actually supports — see openpencil-docs note).
`/models` now returns only deepseek-v4-pro and deepseek-v4-flash;
deepseek-chat / deepseek-reasoner sunset 2026-07-24 and the
deepseek-v3.2 hard-coded in the ark-coding fallback list never
existed. Both v4 models default to thinking enabled and the API
toggles via `{"thinking":{"type":"disabled"}}` — keep
`thinkingMode: 'disabled'` so the app's fast/non-thinking default
stays intact (server reasoning paths honor it; the Zig openai-compat
path doesn't emit the toggle yet, so calls through that path still
get provider-default thinking until it's wired). v4-pro promoted to
full tier; legacy aliases pinned to an exact RegExp so future
deepseek-* variants don't inherit a forced disabled mode.
Bandaid for the unwired toggle: v4-pro gets `timeoutMultiplier: 2`
because its default-on reasoning blows past the orchestrator's
planning timeout on long system prompts (observed in dev: planning
phase falls back, sub-agent then succeeds — UX degraded but
functional). Drop the multiplier once the Zig path actually sends
`thinking:{type:disabled}`.
Don't add a BUILTIN_MODEL_LISTS.deepseek entry — DeepSeek exposes
/v1/models, so let `fetchProviderModels` pull the live catalog
through `/api/ai/provider-models` instead of pinning a snapshot
(the ark-coding `deepseek-v3.2` ghost above shows what those
snapshots drift into).
paddingTop/Right/Bottom/Left are silently dropped by resolvePadding in
the layout engine, causing all four sides to render as 0. Switch every
affected builder to the canonical padding: [T,R,B,L] form.
pen-core's resolvePadding only reads the array/scalar `padding`
field; the CSS-style paddingTop/Right/Bottom/Left siblings I shipped
in 5c275ba1 were silently dropped, so the rail rendered flush. Switch
to padding=[16,12] / [8,12,24,12] / [0,12] and add a regression
assertion that catches the same trap on any future tweak.
Top_nav_bar / bottom_nav / nav_chip_row covered mobile and inline
chrome but desktop dashboards still had to hand-roll their left
sidebar via batch_design. Adds a 240px-wide vertical rail with
icon+label rows, optional brand title, and slate-100 pill bg on the
active item — distinct surface from the existing nav tools so the
decision tree picks it cleanly for "sidebar / side nav / 侧边栏".
Sticky bottom-of-page disclosure card with title, body, accept /
decline buttons (decline-then-accept order), and an optional
"Cookie settings" link for fine-grained consent. Caller positions
the banner; the tool emits the card itself with shadow + 1px slate
border for visual lift above the page content. Plus the v1 corpus
prompt landing-cookie-banner (26 v1 prompts total).
The "Subscribe to newsletter" / "Apply discount code" / "Send chat
message" pattern. Two action variants:
- text (default): pill button with label like "Subscribe"
- icon: 44×44 square icon button (chat send arrow / search apply)
Distinct from add_form_field_v0 (label-above, no inline button)
and add_search_bar_v0 (no trailing action button). Optional
leading_icon adds an icon inside the input itself. Plus the v1
corpus prompt landing-newsletter-signup (25 v1 prompts total).
The "+1 (555) …" pattern from every modern signup / login screen.
A 44px row with leading country selector (flag + dial code +
chevron-down), a 1px slate divider, and the digits input on the
right. Country selector is a button-shape (no actual dropdown
menu); caller handles picker UX as a separate concern. `value`
toggles between placeholder (slate-400) and populated (slate-900).
Third theme-aware v1 (after add_modal_shell_v1 and add_toast_v1).
Same dashed-border "no data yet" tile shape as v0 with a `theme`
param that swaps 5 colors (bg / border / icon / title / subtitle):
- light (default): byte-parity with v0 (slate-50 / slate-300)
- dark: slate-800 bg + slate-600 border + slate-200 title
- system: $color-surface-2 / $color-border / $color-text-primary
refs — requires applySemanticPalette(doc) seeded
Lets dark-theme dashboards keep a matching empty-slot surface
instead of punching a light rectangle out of dark cards.
Visual static representation of a horizontal slider. Track splits
into left fill (accent) + 20×20 thumb (white + accent stroke) +
right remaining (slate), all aligned on a 20px track wrap. Optional
label + value readout row above; `value_suffix` renders "60%" /
"128px" / "0°" style readouts. Pixel math: fill = (width-20) * pct,
auto-collapses fill or remaining at either extreme.
Second theme-aware v1 (after add_modal_shell_v1). Same pill shape as
v0 with a `theme` param:
- light (default): byte-parity with v0 (dark #111827 pill + white fg)
- dark: INVERTED contrast — light pill (#F1F5F9) + dark fg (#0F172A)
- system: $color-text-primary bg + $color-surface fg (inverted swap)
Unlike surface-like v1s (modal-shell), toasts use inverted contrast by
design — a dark pill on light bg, a light pill on dark bg — so the
dark variant flips the pill rather than darkening it.
The "Pro $29/month" column for pricing tables. Tier name + big
price (currency + amount + period) + check-mark feature list + CTA
button. Two emphases: default (slate border + slate CTA) and
featured (accent border + accent CTA + auto "Most popular" badge
unless overridden by explicit `badge` value).
Chat / messaging / customer-support UI message unit. Two variants
via the `side` enum:
- side="left" (default): from-others bubble. Slate-100 fill,
slate-900 text, alignItems=flex-start. Optional `author` text
shown above the bubble (group-chat pattern).
- side="right": from-self bubble. Accent-color fill (customizable
via `accent_color`), white text, alignItems=flex-end. Author
intentionally suppressed on this side — a self-bubble never
carries "You:".
Optional `timestamp` below the bubble on either side.
Max-width mechanic: pen-core has no native max-width primitive, so
`max_width` becomes the bubble's fixed width (clamped 160..480).
Short messages get extra padding on one side — matches every real
chat client (iMessage / WhatsApp / Slack). Message text uses
`textGrowth: 'fixed-width'` + `width: 'fill_container'` to wrap
correctly inside the fixed-width surface.
Full wiring: pen-core builder + pen-mcp handler + schema (into
ext-2, shorter shard — 24 tools vs ext-1's 24 after this) + shim
+ SERVER_BUILDERS + parity CASES + contract allow-list +
elements.md decision tree + triggers + minimal usage for both
sides. Handler test covers 9 cases: registration, left defaults,
left+author, right with self-dropped-author, right+accent_color,
timestamp both sides, max_width clamps (low + high split into
separate tests to avoid cache-interference), textGrowth wiring,
bogus parent_id rejection.
Fills another common UI gap: the "here's an already-uploaded file"
row you see in email composers, chat attachments, and form upload
summaries. Compact horizontal layout: type-icon + filename (bold) +
optional muted size string + optional right-side × remove affordance.
Structure: horizontal frame (slate-50 bg, cornerRadius=8) with
three children:
1. attachment-icon — lucide file-* (caller picks: file / file-
text / file-image / file-video / file-audio / file-archive /
file-spreadsheet / file-code)
2. attachment-meta — vertical frame with filename + optional size
3. attachment-remove — × icon, suppressed via removable=false
Intentionally NOT embedding an upload-progress variant in v0. The
pen-core schema lacks percentage-width primitives, so a %-filled
progress bar would either need a fixed track width (brittle across
parents) or a caller-computed pixel value (awkward API). Callers
who need the uploading state compose `add_progress_bar_v0` directly
below the row — cleaner separation.
Wired through all standard points: schema into ext-1 (balanced
shards 23/23 after upload-dropzone landed there last commit) +
shim + SERVER_BUILDERS + parity CASES + contract allow-list +
elements.md decision tree + triggers + minimal usage.
Handler test covers 7 cases: registration + minimal (no size) +
size rendered + custom icon + removable=false + default icon +
bogus parent_id rejection.
Fills the auth-flow gap: 2FA / PIN / phone-verification codes.
Horizontal row of N square slots (4..8), one digit per slot.
Renders three states per caller intent:
- blank (no `digits`): all slots empty, `focused_index` marks
the currently-typing slot with an accent-color 2px outline
- partial: first M slots filled with digit text, slot M+1
focused, rest empty
- full: all N slots filled (final submittable state)
Filled slots get role=otp-slot-filled + slate-700 border + 20/600
digit text. Focused empty slot gets role=otp-slot-focused +
2px accent border. Blank unfocused slots get role=otp-slot +
1px slate-300 border.
Wired through all standard points — schema into ext-2 (shorter
shard) + shim + SERVER_BUILDERS + parity CASES + contract
allow-list + elements.md decision tree + triggers + minimal
usage for each state.
Handler test covers 8 cases: registration + defaults (6 blank
focused-first) + partial state / full state / length clamp low
(< 4 → 4) + length clamp high (> 8 → 8) + accent color override
+ bogus parent_id rejection.
Fills a real gap in the element-tool family: upload / drag-and-
drop surfaces. Dashed border + cloud icon + two-line instruction
("Drop files to upload" / "or click to browse") — the classic
pattern from every modern file-upload UI.
Deliberately structurally similar to add_empty_chart_v0 (dashed
border + icon + title/subtitle) but semantically distinct:
- empty_chart = "chart widget will render when data arrives"
(320×200, icon chart-typed)
- upload_dropzone = "users drop files here" (480×200, icon
semantic: upload-cloud / upload / file-up)
elements.md routes them by intent, and the tool descriptions
cross-reference each other to prevent the AI from picking the
wrong one on ambiguous prompts.
Wired through all the standard points per the add-new-tool
checklist: builder + handler + schema (into ext-1, the shorter
shard) + shim + SERVER_BUILDERS + parity CASES + contract
allow-list + elements.md decision tree + keyword triggers +
minimal usage. Handler test covers 5 cases: defaults, dashed
stroke, overrides, size clamping, bogus parent_id rejection.
Ships the first theme-aware element builder demonstrating the v1
contract end-to-end. `buildModalShellV1({ title, theme })` accepts
three theme variants:
- `'light'` (default): byte-parity with buildModalShell v0 —
same hex literals, same role tree, same structural shape.
Structural test asserts stripIds(v0) === stripIds(v1) for
the default-theme path.
- `'dark'`: hardcoded dark-palette hex (#1E293B card, #F1F5F9
title, #94A3B8 muted text). No \$refs — this path is for
callers who want a dark modal without the theme-switching
infrastructure.
- `'system'`: emits \$color-surface / \$color-text-primary /
\$color-text-muted refs. Renders track \`themes.Mode\` at
paint time. Requires \`applySemanticPalette(doc)\` to have
been seeded; if not, refs resolve to undefined (caller's
responsibility per the v1 contract).
End-to-end tests validate the 'system' path's round-trip through
resolveColorRef for both Light (→ #FFFFFF) and Dark (→ #1E293B)
modes. That's the full chain working:
buildModalShellV1({theme:'system'}) → tree with \$refs
→ applySemanticPalette(doc) → palette seeded
→ resolveColorRef(ref, doc.variables, {Mode:'Dark'}) → hex
One intentional design note tested: scrim stays #000000 in BOTH
light and dark themes. Modal backdrops are a "dim everything
below" effect, not a themeable surface — dimming a dark surface
with a dark color is a better visual than a themed shade.
18 tests. v0 byte-parity verified against the existing
buildModalShell for full structural equality. This is the
reference implementation for all subsequent v1 tools (top-10
offenders per the dark-theme audit).
Ships the canonical 14-token palette called for in the dark-theme
audit (openpencil-docs/superpowers/notes/2026-04-22-dark-theme-
defaults-audit.md §role clusters). Every token has paired Light +
Dark values on a single `Mode` theme axis.
API surface:
- getSemanticPalette() → {themes, variables} for merge
- getSemanticPaletteHex(mode='Light') → flat Record<name, hex>
- applySemanticPalette(doc) → non-destructive merge (user-
defined variables + theme axes WIN on collision; palette is
purely additive)
- hasSemanticPalette(doc) → runtime check for v1 tools before
emitting \$color-* refs
- getSemanticPaletteDescription(name) → human-readable string
for token-picker UI
- SEMANTIC_PALETTE_NAMES + theme-axis constants exported
The 14 tokens:
- Surfaces: color-surface, color-surface-2, color-surface-3,
color-bg-deep
- Borders: color-border, color-border-strong
- Text: color-text-primary, color-text-body, color-text-muted,
color-text-subtle
- Semantic: color-accent, color-destructive, color-success
- Other: color-scrim (with alpha for modal backdrop)
Intentionally NOT wired into createEmptyDocument(). Seeding by
default would alter every existing document on re-save and
violate the v0 byte-parity contract (the whole point of the
audit). v1 tools will call applySemanticPalette(doc) as a pre-
flight, OR the app shell offers a "enable dark theme" user
action that triggers the apply.
29 tests cover: palette shape (14 variables, 2 themed values each,
hex-formatted, light≠dark), hex getter for both modes, apply
non-mutation + user-var-wins-on-collision + additive theme-axis
merge, hasSemanticPalette (empty / full / partial), and full
round-trip through the existing resolveVariableRef / resolveColorRef
paths for every palette name.
Two tsc errors surfaced by a later tsc run:
1. browser-image-search-fetcher.test.ts — imported `beforeEach`
but never used; also `spy.mock.calls[0]` typed as empty tuple
since vi.fn()'s signature isn't inferred. Cast via `unknown` +
explicit tuple shape.
2. chart-builders-visual-smoke.test.ts — custom-dimensions case
passed `width`/`height` to buildChartLine. The real shape is
`point_spacing` + `chart_height`. Fixed the test to use the
actual param names (test itself wasn't broken, just the type).
Geometric invariants for the three chart builders (bars/line/pie)
that a rendering failure would start from. Can't run Skia
headlessly in unit tests (CanvasKit WASM is heavy + GPU-context-
dependent), so this is the cheap smoke layer that catches shape-
level regressions before they reach the renderer. The app-level
debug_screenshot MCP tool gives us real visual regression on top.
Per chart type:
- buildChartBars: 8 variants (default, all-equal, single, small
values, large values, custom dims, zeros, empty-throws).
Asserts one chart-bar per value, all dims finite.
- buildChartLine: 9 variants (smooth, monotonic, flat, two-point,
spike, fractional, custom dims, single-value, empty-throws).
Asserts chart-line geometry present, coords finite.
- buildChartPie: 9 variants (equal, skewed, two, many-thin,
custom diameter, donut at 0.5 and 0.9 ratio, single 100%,
empty-throws, all-zero-throws). Asserts one slice per value,
startAngle/sweepAngle finite, sweepAngle positive, total
sweep = 360°.
Cross-chart invariants: same input length → same geometry-child
count; all three types produce finite-coord trees on identical
input.
Empty-input behavior: all three builders throw with clear
messages. Test pins the throws as intended behavior — the
alternative (silently returning an empty tree) would let an
all-zeros dataset produce a "chart is there but invisible" UI
bug that's much harder to diagnose than the explicit throw.
Pins that text-carrying element builders preserve the caller's
byte representation verbatim — no silent normal-form conversion,
no zero-width stripping, no fullwidth↔ASCII collapse.
Tests each of NFC/NFD/NFKC/NFKD forms through 6 representative
builders (heading / body-text / list-row / form-field / faq-item /
comment), plus 5 targeted fixtures:
- Zero-width joiner mid-word ("emoji" stays 6 codepoints)
- BOM at string start
- ZWJ emoji family sequence (4-person glyph)
- Vietnamese combining-marks (NFC vs NFD both preserved as-is)
- Halfwidth/fullwidth CJK distinction (NFKC would collapse
fullwidth "A" to ASCII "A"; we assert the builder does NOT)
Why this matters: macOS ships filenames in NFD, Windows/web in
NFC; copy-paste carries any form; some CJK inputs emit
precomposed, others decomposed base+combining. Exact-match
lookups in external systems (especially emoji-less fallback
keys) break silently if the builder pre-empts the downstream
validator's normalization decision. Builders must pass through
bytes unmodified.
Adds an N-tool for the labeled date input + calendar-icon trigger.
Emits ONLY the CLOSED state; the open month grid lives in
add_calendar_grid_v0 and is typically shown inside a popover,
not stacked directly below. Two visual states:
- placeholder (no value): slate-400 "Select date" + calendar icon
- populated (value): slate-900 date text + calendar icon
`clearable: true` adds a small X affordance to the right of the
value (only when value is present — no-op for the placeholder
state since there's nothing to clear). `required: true` appends
" *" to the label.
Keeping closed + open as separate tools is intentional: AI specs
often ask for only the closed trigger inside a form, and a single
combined tool would either force an unwanted grid or require a
mode flag that splits the parameter surface. Separate narrow tools
compose cleanly via batch_design when a designer DOES want both.
Wired through all 3 paths + parity/contract/design-prompt tests.
Handler test covers 7 cases: placeholder state fills, populated
value fills, clearable X behaviors (both present + absent value),
custom placeholder override, required marker, bogus parent_id
rejection.
Adds an N-tool for the floating card that drops from a "⋯ more"
button or appears on right-click. Emits the OPEN state: vertical
stack of padded icon+label rows in a white card with subtle stroke
and shadow. Positioning and show/hide are caller concerns (same
philosophy as add_modal_shell_v0 / add_toast_v0).
Destructive items (destructive=true) render in red with role
`action-menu-item-destructive` so renderers can style the hover
state separately. divider_before=true on any item (except first,
where it's ignored) inserts a 1px hairline above — useful for
"Edit / Share / Report / Delete" grouping patterns.
Wired through all 3 paths + parity/contract/design-prompt tests.
Handler test covers 7 cases: simple list, destructive red fill,
divider between groups, leading-divider ignored, label-only no
icon, width clamp, bogus parent_id rejection.
Adds an N-tool for the "no data yet" tile that sits in the exact
footprint where a real chart would go. Default 320×200 matches the
line/bar chart default footprint; dashed border + slate-50 fill +
slate icon signal "chart slot, currently empty". Caller can hint
at the widget type via icon ("line-chart" / "pie-chart" / default
"bar-chart-2").
Intentionally separate from add_empty_state_v0 — that tool is for
inbox/onboarding/no-results full-page empties (has optional CTA,
no dashed border). add_empty_chart_v0 reads as "chart widget is
live, just lacks data yet" rather than "nothing to show on this
screen at all".
Wired through all 3 paths + parity/contract/design-prompt tests.
Handler test covers 6 cases: defaults + dashed stroke + icon
override + size clamping + title/subtitle override + bogus
parent_id rejection.
Adds an N-tool for the "variable-N pill-plus-cursor" pattern: a
labeled form control that holds N removable tag pills followed by
an inline placeholder caret. Wrap layout (layoutWrap=wrap) so
chips flow onto additional rows as they accumulate — a horizontal
fit_content row would clip after ~4 chips.
Each chip: pill (cornerRadius=16, slate-100 fill, padding 10/4/6/6
L/R/T/B) + label + 14×14 lucide "x". Default caret placeholder is
"Add tag…" when chips is empty; caller overrides with `placeholder`
(e.g. "Enter emails" for recipient lists).
Wired through all 3 paths with matching handler test (7 cases) +
parity tests auto-picking-up the entry. elements.md: decision tree
§54, trigger list, minimal usage (populated + empty).
Adds an N-tool for one row in a FAQ list. Collapsed (default):
bold question + chevron-right header. Expanded (expanded=true):
chevron-down + multi-line answer paragraph beneath. Optional
show_divider draws a 1px slate-200 rectangle at the bottom for
visual separation between items (no implicit padding — caller
stacks in a vertical parent).
Wired through all 3 paths (pen-core buildFaqItem + pen-mcp handler
+ apps/web shim + Nitro SERVER_BUILDERS); both parity tests and
the stale-integration guard auto-pick-up the entry. Handler test
covers 5 cases: collapsed default, expanded with answer, expanded
without answer (guards against undefined), show_divider hairline,
bogus parent_id rejection.
Adds an N-tool for list/table footer pagination: row of page-
number pills flanked by optional prev/next chevron buttons. Active
page renders filled with the accent color, inactive pages are
ghost. Long ranges collapse with "…" Google-style (always show 1
and total, plus a ±siblings window around current).
Wired through all 3 paths: pen-core buildPagination + pen-mcp
handler + apps/web browser shim + Nitro SERVER_BUILDERS. Both
parity tests (shim-server-parity, element-tool-registry-parity)
pick up the entry automatically. Handler test covers 7 cases:
small range no ellipsis, 10-page ellipsis, start-edge current,
accent override, show_arrows=false, total=1 single pill, bogus
parent_id rejection.
Also updates packages/pen-ai-skills/skills/phases/generation/
elements.md: decision tree §52, keyword triggers (pagination /
page nav / 分页 / 分页条), minimal usage example. The stale-
integration guard (design-prompt-elements.test.ts) now passes.
Feeds a 10,200-char Lorem-ipsum through every text-accepting
element builder (heading, body-text, list-row subtitle, form-field
placeholder, textarea placeholder, alert, toast, quote-block,
tooltip, comment body, notification-row body, modal-shell subtitle)
and asserts: build doesn't throw, computeLayoutPositions doesn't
throw, no NaN/Infinity coords leak in, and content is preserved
verbatim (no silent truncation inside the builder — that's a
caller/renderer concern).
Also pins a 100k-char stress on buildHeading + buildBodyText with
a <100ms budget — catches accidental O(n²) in any character scan.
Dark slate (#334155) box + centered white play icon + optional
caption. Default 320×180 for 16:9. The "future video embed"
affordance — semantically distinct from add_image_placeholder_v0:
dark bg + play icon reads as "play me later", not "picture coming".
Play affordance is a lucide `play` icon_font, NEVER a hand-drawn
path triangle (classic LLM anti-pattern for video placeholders).
Regression test locks that invariant.
Wired across all three paths + elements.md entry (44b) + keyword
map + example + parametric test CASES in 8 files. Handler test
has 6 assertions including the path-vs-icon_font anti-pattern
guard.
Tool count: 55 → 56. Test count: 3225 → 3241 (+16).
