PPT Master Skill

AI-driven multi-format SVG content generation system. Converts source documents into high-quality SVG pages through multi-role collaboration and exports to PPTX.

Core Pipeline: Source Document → Create Project → [Template] → Strategist → [Image_Generator] → Executor Live Preview → Quality Check → Post-processing → Export

[!CAUTION]

🚨 Global Execution Discipline (MANDATORY)

This workflow is a strict serial pipeline. The following rules have the highest priority — violating any one of them constitutes execution failure:

SERIAL EXECUTION — Steps MUST be executed in order; the output of each step is the input for the next. Non-BLOCKING adjacent steps may proceed continuously once prerequisites are met, without waiting for the user to say "continue"

BLOCKING = HARD STOP — Steps marked ⛔ BLOCKING require a full stop; the AI MUST wait for an explicit user response before proceeding and MUST NOT make any decisions on behalf of the user

NO CROSS-PHASE BUNDLING — Cross-phase bundling is FORBIDDEN. (Note: the Eight Confirmations in Step 4 are ⛔ BLOCKING — the AI MUST present recommendations and wait for explicit user confirmation before proceeding. Once the user confirms, all subsequent non-BLOCKING steps — design spec output, SVG generation, speaker notes, and post-processing — may proceed automatically without further user confirmation)

GATE BEFORE ENTRY — Each Step has prerequisites (🚧 GATE) listed at the top; these MUST be verified before starting that Step

NO SPECULATIVE EXECUTION — "Pre-preparing" content for subsequent Steps is FORBIDDEN (e.g., writing SVG code during the Strategist phase)

NO SUB-AGENT SVG GENERATION — Executor Step 6 SVG generation is context-dependent and MUST be completed by the current main agent end-to-end. Delegating page SVG generation to sub-agents is FORBIDDEN

SEQUENTIAL PAGE GENERATION ONLY — In Executor Step 6, after the global design context is confirmed, SVG pages MUST be generated sequentially page by page in one continuous pass. Grouped page batches (for example, 5 pages at a time) are FORBIDDEN

SPEC_LOCK RE-READ PER PAGE — Before generating each SVG page, Executor MUST read_file <project_path>/spec_lock.md. All colors / fonts / icons / images MUST come from this file — no values from memory or invented on the fly. Executor MUST also look up the current page's page_rhythm (anchor / dense / breathing), page_layouts (which template SVG to inherit, if any), and page_charts (which chart template to adapt, if any). Empty / absent entries are intentional Strategist signals — see executor-base.md §2.1. This rule exists to resist context-compression drift on long decks and to break the uniform "every page is a card grid" default

SVG MUST BE HAND-WRITTEN, NOT SCRIPT-GENERATED — Every SVG page is written by the main agent directly, one page at a time (see rules 6 and 7). Writing or running a Python / Node / shell script that produces the SVG files in batch — looping over pages, templating from data, or emitting them via a generator — is FORBIDDEN, including under "save tokens", "quick draft", or "user is in a hurry" pretexts. The script-generation path was tried on a feature branch and abandoned: cross-page visual consistency depends on per-page authoring with full upstream context, which a generator script cannot reproduce

FOLLOW DETERMINISTIC ROUTING RULES — Do not add blocking routing questions when this skill defines a route. If the user request violates a route precondition, state the required prerequisite and stop that route instead of asking the user to choose around the rule. Ordinary finite options, stylistic preferences, and recoverable details are surfaced with a recommended value plus alternatives at the next existing confirmation gate.

[!IMPORTANT]

🌐 Language & Communication Rule

Response language: match the user's input and source materials. Explicit user override (e.g., "请用英文回答") takes precedence.

User-facing option labels: when presenting confirmations, brief proposals, choices, or finite option sets, use the user's language for labels and explanations. English enum IDs / file fields may appear in parentheses for precision, but never rely on English-only labels such as deck, layout, mirror, or fidelity without a localized explanation.

Template format: design_spec.md MUST follow its original English template structure (section headings, field names) regardless of conversation language. Content values may be in the user's language.

[!IMPORTANT]

Standalone Workflows

Route authority: Use workflows/routing.md before entering the main pipeline or any standalone workflow.

Registry: Use workflows/index.md for the complete workflow list, triggers, preconditions, exclusions, outputs, and blocking points.

PPTX Route Boundary

User intent	Route
Raw PPTX template plus new material/topic, generate a PPTX	`template-fill-pptx`
Existing PPTX, preserve page count/order and slide wording 1:1, improve layout	`beautify-pptx`
Existing PPTX as source material, rethink outline or change page count/order	Main pipeline via `ppt_to_md.py` plus PPTX intake
Build a reusable template package from a PPTX/design reference	`create-template`, then return with the generated template directory path
Finished PPTX, keep content/layout stable and add notes/audio/timing/transitions	`native-enhance-pptx`

MUST: Raw .pptx template plus "generate PPTX" routes to template-fill-pptx by default. The SVG generation route consumes only an explicit template directory path that already contains a valid template design_spec.md.

MUST: Beautify is strictly 1:1. Any split, merge, drop, reorder, or page-count change routes to the main pipeline.

FALLBACK: Ambiguous requests such as "make this PPT more professional" require exactly one discriminator question: preserve original page count/order and slide wording, or treat the deck as source material and restructure it?

Workflow

Step 1: Source Content Processing

🚧 GATE: User has provided source material (PDF / DOCX / EPUB / URL / Markdown file / text description / conversation content — any form is acceptable).

No source content? When the user supplies only a topic name or requirements without any file or substantive description, run the topic-research workflow first, then return here with its products as input.

When the user provides non-Markdown content, convert immediately:

User Provides	Command
PDF file	`python3 ${SKILL_DIR}/scripts/source_to_md/pdf_to_md.py <file>`
DOCX / Word / Office document	`python3 ${SKILL_DIR}/scripts/source_to_md/doc_to_md.py <file>`
XLSX / XLSM / Excel workbook	`python3 ${SKILL_DIR}/scripts/source_to_md/excel_to_md.py <file>`
CSV / TSV	Read directly as plain-text table source
PPTX / PowerPoint deck	`python3 ${SKILL_DIR}/scripts/source_to_md/ppt_to_md.py <file>` for Markdown content; after Step 2 `import-sources`, standard PPTX intake is also written to `<project>/analysis/`
EPUB / HTML / LaTeX / RST / other	`python3 ${SKILL_DIR}/scripts/source_to_md/doc_to_md.py <file>`
Web link	`python3 ${SKILL_DIR}/scripts/source_to_md/web_to_md.py <URL>`
WeChat / high-security site	`python3 ${SKILL_DIR}/scripts/source_to_md/web_to_md.py <URL>` (requires `curl_cffi`, included in `requirements.txt`)
Markdown	Read directly

Office vector assets (EMF/WMF) from DOCX/PPTX sources: doc_to_md.py / ppt_to_md.py extract embedded Office vector images (.emf/.wmf) alongside bitmap images. After import-sources, these land in images/ together with image_manifest.json and are first-class assets in §VIII Image Resource List.

Do NOT convert EMF/WMF to PNG. The PPT Master pipeline preserves them as external references (finalize_svg.py skips them) and svg_to_pptx.py embeds them as PPTX-native media via image/x-emf / image/x-wmf MIME — PowerPoint renders them at full vector fidelity. Converting via LibreOffice/Inkscape introduces CJK font substitution drift and rasterization loss; the original EMF/WMF is always higher fidelity than the converted PNG.

Browser-based live preview cannot render EMF (will show blank) — this is expected; the PPTX output is the source of truth.

✅ Checkpoint — Confirm source content is ready, proceed to Step 2.

Step 2: Project Initialization

🚧 GATE: Step 1 complete; source content is ready (Markdown file, user-provided text, or requirements described in conversation are all valid).

python3 ${SKILL_DIR}/scripts/project_manager.py init <project_name> --format <format>

Format options must be named with concrete dimensions. Default: ppt169 = 1280x720, viewBox="0 0 1280 720". Other examples: ppt43 = 1024x768, story = 1080x1920, banner = 1920x1080. For the full format list, see references/canvas-formats.md.

Import source content (choose based on the situation):

Situation	Action
Has source files (PDF/MD/etc.)	`python3 ${SKILL_DIR}/scripts/project_manager.py import-sources <project_path> <source_files...> --move`
User provided text directly in conversation	No import needed — content is already in conversation context; subsequent steps can reference it directly

For PPTX sources, import-sources automatically runs the standard intake enrichment:

python3 ${SKILL_DIR}/scripts/pptx_intake.py <project_path>/sources/<source.pptx> -o <project_path>/analysis

For each PPTX it writes <stem>.identity.json (canvas, theme palette/fonts, observed usage) and <stem>.slide_library.json (text slots, geometry, native tables, native chart caches), and merges that deck's Strategist-facing digest into the single multi-deck index analysis/source_profile.json (decks[], one self-contained entry per source deck, with prefixed artifact pointers). In the main generation path these are source facts and recommendation candidates, not replica constraints; beautify and template-fill workflows decide separately which fields become locked constraints.

Multi-deck: several PPTX files may be imported into one main-pipeline project — each gets its own <stem>.* artifacts and a deck entry in source_profile.json. source_profile.json stays the single must-read index (one entry for a one-deck project, several for a combined-source project). Stems must be distinct; re-importing the same stem replaces that deck's entry. The beautify / template-fill workflows remain single-deck (1:1 to one chosen source deck) and read that deck's <stem>.* artifacts.

⚠️ MUST use --move (not copy): all source files — Step 1's generated Markdown, original PDFs / MDs / images — go into sources/ via import-sources --move. After execution they no longer exist at the original location. Intermediate artifacts (e.g., _files/) are handled automatically.

✅ Checkpoint — Confirm project structure created successfully, sources/ contains all source files, converted materials are ready. Proceed to Step 3.

Step 3: Template Option

🚧 GATE: Step 2 complete; project directory structure is ready.

Default — free design. Proceed directly to Step 4. Do NOT query any *_index.json unless triggered. Do NOT ask the user. Do NOT proactively suggest, hint at, or fuzzy-match any template based on content, slug-like words, or vague style descriptions.

Hard boundary — raw PPTX template references are not Step 3 templates. PPTX-as-source remains valid in Step 1 / Step 2, and raw PPTX template + generated PPTX routes to template-fill. But if the user wants the SVG/template-based generation route from that PPTX, stop before Step 3. The user must first run workflows/create-template.md, then return with the generated template directory path. Step 3 only consumes an explicit template directory that already contains design_spec.md with kind: brand / kind: layout / kind: deck.

Do not reinterpret this boundary as 1:1 redesign or free SVG generation. Use template-fill for raw PPTX template + generated PPTX requests; use beautify only when the source deck's page count, order, and wording are preserved.

Template flow triggers ONLY on explicit directory paths supplied by the user in their initial message. The trigger rule is mechanical, not interpretive:

User input contains	Step 3 action
One or more explicit template directory paths (each resolves to a directory containing `design_spec.md` with `kind: brand` / `kind: layout` / `kind: deck` in its YAML frontmatter)	Read each spec's `kind`, dispatch per the kind matrix below, fuse if multiple
Anything else — bare template names ("用 academic_defense"), style descriptions ("麦肯锡风格"), brand mentions ("招商银行风格"), vague intent ("想用个模板"), or silence	Skip Step 3, free design

There is no slug matching, no name lookup, no fuzzy resolution. A name without a path does not trigger — the user must give a path the AI can cd into.

Style descriptions ("麦肯锡风格" / "Keynote 风" / "极简风" / etc.) never trigger Step 3. They flow into Strategist's Eight Confirmations as a style brief (color / typography / tone in confirmations e–g).

Bare names ("academic_defense", "招商银行", "anthropic") do NOT trigger Step 3 even if a matching directory exists in the library. The user must give a path. AI must not "helpfully" resolve a name to a path.

"What templates exist?" is out-of-band Q&A — answer by listing entries from brands_index.json / layouts_index.json / decks_index.json together with their paths. Listing alone does not advance the pipeline; the user must send a path back to trigger Step 3.

To create a new layout or deck, read workflows/create-template.md. To create a new brand, read workflows/create-brand.md.

Three template kinds

The architecture has three independent reference bundles. Full schema in docs/zh/templates-architecture.md. Summary:

Kind	Physical dir	Contains	Frontmatter
brand	`templates/brands/<id>/`	identity-only segment: color / typography / logo / voice / icon style	`kind: brand`
layout	`templates/layouts/<id>/`	structure-only segment: canvas / page structure / page types / SVG roster	`kind: layout`
deck	`templates/decks/<id>/`	full replica: identity + structure + middle (template overview) segments	`kind: deck`

Segment ownership (governs fusion override priority):

Segment	Sections	Owner kind on fusion
Identity	Color Scheme / Typography / Logo / Voice & Tone / Icon Style	brand
Structure	Canvas / Page Structure / Page Types / SVG Roster	layout
Middle	Template Overview (use cases / design intent)	deck (no other kind writes this)

Single-path dispatch

User path's `kind`	Step 3 action
`kind: brand`	`design_spec.md` + non-image assets → `<project>/templates/`; logo / illustration / icon bitmaps → `<project>/images/`. Strategist locks identity segment as truth; structure stays free.
`kind: layout`	`design_spec.md` + SVG roster → `<project>/templates/`; any bitmap assets → `<project>/images/`. Strategist locks structure; identity decided in Eight Confirmations e–g.
`kind: deck`	`design_spec.md` + template SVGs → `<project>/templates/`; logos / backgrounds / other bitmaps → `<project>/images/`. Strategist locks all segments; Eight Confirmations narrows to deck-content fields (audience / page count / outline / tone tweaks).

TEMPLATE_DIR=<user-supplied path>
# Bitmaps join the project's single runtime image pool (images/, referenced as
# ../images/); the spec + template SVGs + other non-image assets stay in
# templates/ as design reference the Strategist/Executor read but never render.
cp -r ${TEMPLATE_DIR}/* <project_path>/templates/
find <project_path>/templates -type f \( -iname '*.png' -o -iname '*.jpg' -o -iname '*.jpeg' -o -iname '*.gif' -o -iname '*.webp' -o -iname '*.bmp' \) -exec mv {} <project_path>/images/ \;

The same split applies to all three kinds — bitmaps always land in images/, the rest in templates/. The spec's kind field tells Strategist how to read the templates/ side; downstream code doesn't distinguish. (Template SVGs in templates/ are reference material only — the rendered pages live in svg_output/ and reference images via ../images/.)

Multi-path fusion

When the user gives two or more paths of different kinds, Step 3 fuses them into a single <project>/templates/design_spec.md. Default granularity is segment-level integer replacement — entire identity / structure / middle segments are taken from the highest-priority source for that segment, no implicit field-level mixing.

Override priority by segment:

Combination	Identity from	Structure from	Middle from
brand only	brand	(free design)	(none)
layout only	(free design)	layout	(none)
deck only	deck	deck	deck
brand + layout	brand	layout	(none)
brand + deck	brand (overrides deck)	deck	deck
layout + deck	deck	layout (overrides deck)	deck
brand + layout + deck	brand	layout	deck

Field-level micro-adjustment (e.g. "use anthropic brand but primary changed to #FF0000") is not part of Step 3 fusion — it flows into Strategist Eight Confirmations e–g as a normal user request.

Same-kind multiple paths — conflict resolution

When the user gives two paths of the same kind (e.g. brands/anthropic + brands/google), Step 3 surfaces a conflict prompt before fusing — like resolving a git merge conflict:

AI: 你给了两个 brand，检测到段级冲突：
    - Color Scheme（Anthropic 橙红 vs Google 多色）
    - Typography（Styrene/AnthropicSans vs GoogleSans/Roboto）
    - Logo（Anthropic 标 vs Google 标）
    - Voice & Tone（restrained vs friendly）
    - Icon Style（stroke vs filled）

    要 (a) 全部按 Anthropic / (b) 全部按 Google / (c) 逐段挑？

Rules:

Default: no implicit ordering — every cross-source segment difference is reported as a conflict
Only when the user picks (c) does AI walk through each segment one by one
Field-level conflicts are out of scope — segment-level only
Three or more same-kind paths are not supported — ask the user to converge to at most two

Fused spec provenance

When fusion happens (any multi-path case), the resulting <project>/templates/design_spec.md carries a provenance block immediately under its H1:

> **Fused from:**
> - deck: `templates/decks/招商银行/` （base）
> - brand: `templates/brands/anthropic/` （identity override）
> - layout: `templates/layouts/academic_defense/` （structure override）
> - conflicts resolved: Color Scheme from anthropic（user picked a）

Single-path Step 3 does not add provenance (the source is self-evident from the copied files).

✅ Checkpoint — Default path proceeds to Step 4 without user interaction. If the user supplied one or more explicit template paths, those have been dispatched (or fused) into <project_path>/templates/ before advancing.

Step 4: Strategist Phase (MANDATORY — cannot be skipped)

🚧 GATE: Step 3 complete; default free-design path taken, or (if triggered) template files copied into the project.

First, read the role definition:

Read references/strategist.md

⚠️ Mandatory gate: before writing design_spec.md, Strategist MUST read_file templates/design_spec_reference.md and follow its full I–XI section structure. See strategist.md Section 1.

Artifact ownership: fact-channel and source/derived artifact boundaries are defined in references/artifact-ownership.md. This Step uses those ownership rules; it does not redefine them.

<project_path>/analysis/ is the project's intermediate-analysis folder: the canonical home for machine-extracted source/asset facts — the PPTX intake bundle (source_profile.json index + per-deck <stem>.identity.json / <stem>.slide_library.json) and image_analysis.csv. It holds facts, not design contracts — design_spec.md / spec_lock.md stay at the project root. The MUST-read contract covers only the compact structured data files (.json / .csv); other artifacts that may live under analysis/ (e.g. a beautify source_svg_import/ vector reference package) are NOT bulk-read — they are read selectively only when a specific workflow step calls for them. Before the Eight Confirmations, Strategist MUST read the auto-extracted fact files already in analysis/ — currently source_profile.json (PPTX intake), when present. This file is the multi-deck index: read it once for the decks[] digests (canvas / chart / table entries per source deck), then open a specific deck's <stem>.identity.json / <stem>.slide_library.json only if you need its full raw facts. Use these entries as factual source context (format default + content facts); when several decks are present, synthesize across all of them. The source's palette / typography / visual identity are a reference, not a constraint: the main pipeline may inherit them where they fit the content and the confirmed style, or design fresh where they don't — the Strategist's judgment, never an obligation to either keep or discard. (Template-fill preserves the native source design by editing cloned slides directly; beautify defaults to the source identity but still follows the confirmed values; the main pipeline treats source identity as reference only and defaults to fresh design.) (image_analysis.csv lands later, at the image-analysis step below, and is the authoritative regenerated image-fact view there — re-derived from the live images/ folder, not a durable store.)

Channel ownership — read each fact once from its owning channel. In the main pipeline the content contract is the Markdown (sources/<stem>.md): text, tables, and chart data values all come from there (ppt_to_md now transcribes native chart data into Markdown tables). The analysis/ chart / table entries are a structural digest for outline decisions (which slides carried charts, type, series names) — not a second copy of the values; do NOT also pull chart values from <stem>.slide_library.json in the main pipeline. The <stem>.slide_library.json full structured data is owned by the direct-PPTX workflows: template-fill uses it as the native fill contract; beautify uses it for native chart / table data while keeping slide text from the Markdown.

Eight Confirmations (full template: templates/design_spec_reference.md):

⛔ BLOCKING: present the Eight Confirmations and wait for explicit user confirmation or modification before outputting Design Specification & Content Outline. This is the single core confirmation gate — once the final confirmation lands, all subsequent steps proceed automatically. The default Confirm UI delivers the gate in two tiers (anchors → re-derive → realization; see below); the chat fallback mirrors the same two steps.

Canvas format
Page count range
Target audience
Style objective
Color scheme
Icon usage approach
Typography plan, including formula rendering policy
Image usage approach

Confirm UI Auto-Launch (Mandatory — default visual confirmation surface): by default the Eight Confirmations are presented through an interactive local page in two tiers within one browser session — Tier 1 confirms the anchors; the AI then re-derives the realization layer from the user's actual anchors; Tier 2 confirms that layer. Color swatches, live font previews, candidate picks; the chat path is the always-valid fallback. scripts/docs/confirm_ui.md owns the schema, server lifecycle, port strategy, and fallback details; this section keeps the orchestration contract. The split:

Tier	Confirms	Driven by
1 — anchors	canvas · audience + core message + `content_divergence` + `delivery_purpose` (PPT only — omitted on non-PPT canvases) (all §c key info) · `mode` + `visual_style`	the source + user intent
2 — realization (re-derived from Tier 1)	page count · color · typography (font + size) · icons · formula policy · image usage + generated-image style · generation mode · refine-spec toggle	the confirmed Tier 1

Why two tiers. Every realization field is anchored by the same few choices (visual_style anchors color / icon / typography / image; delivery_purpose sets the body size, page density, and the page-count recommendation). Confirming anchors first, then re-deriving, means Tier 2's candidates fit the user's real anchors instead of your originals — the coherence reconciliation below is done by construction on this path. Page count is a derived field (content volume × delivery_purpose), which is why it lives in Tier 2, not up front.

Steps:

⛔ Steps 2 → 3 → 4 are ONE uninterrupted run — do NOT yield to the user mid-flow. When the tier-1 --wait (step 2) returns, the AI immediately and autonomously continues to step 3 (re-derive + write Tier 2) and step 4 (--wait-only) in the same turn: do not summarize, ask a question, report progress, or end the turn in between. The browser is sitting on a "deriving…" spinner polling for the Tier 2 you must write next — stopping here strands the page and the user must prod you in chat to finish (a bug, not the intended flow). The tier-1 confirmation is an intermediate machine handoff, not a stopping point. The single ⛔ BLOCKING wait is the final confirmation at the end of step 4. (Chat-fallback path — only when the page never opened — is the exception: there you do present each tier in chat and wait for a reply.)

Write Tier 1 to <project_path>/confirm_ui/recommendations.json with "tier": 1 and only the anchor fields. Enumerable anchors (canvas / mode / visual_style / delivery_purpose) name a recommended canonical id in a recommend block (the page lists common options from confirm_ui/static/catalogs.json); visual_style also carries the ≥3-style visual_style_spectrum (safe / shifted / bold — same hard rule as h.5). audience and content_divergence are plain { "value": "<free text>" }. content_divergence is the free-text field shown under audience in §c — how closely to follow the source vs how freely to reshape it (blank = balanced; facts stay sourced at every level); it is consumed by Strategist when authoring §IX, recorded in design_spec.md §I, carries no page-count coupling, and is not written to spec_lock.md. Set lang to the page language; visible text matches lang, or provide bilingual name_zh / name_en + note_zh / note_en.
Launch + wait for Tier 1. Background launch; the parent returns when the page writes the tier-1 result.json. Long tool timeout — 600000 ms (the --wait ≈590 s budget):
```
python3 ${SKILL_DIR}/scripts/confirm_ui/server.py <project_path> --daemon --wait
```
Page opens at http://localhost:5050 — the same port as the Step 6 live preview (they never run at once: this page shuts down at the end of Step 4). If 5050 is held, the launcher auto-advances (5051, …) — read the actual URL from the launch log and report it. The page does not close after Tier 1: it shows a "deriving…" state and polls for Tier 2. Launch or wait failure is non-fatal: if it fails or times out (flask missing, port blocked, no GUI / remote / web host), do NOT troubleshoot — on any non-zero exit, re-check result.json once (a fresh status: tier1-confirmed) before dropping to the chat fallback. On success (exit 0 with a tier-1 result), do not pause or report — go straight to step 3 in the same turn.
Re-derive Tier 2 from the confirmed anchors, then write it — immediately, same turn (the page is polling for it). Read the tier-1 result.json (status: tier1-confirmed). Using the user's actual confirmed anchors (not your originals), author the realization candidates and overwrite recommendations.json with "tier": 2: page count (content volume × delivery_purpose); color, typography, and generated-image style as generative ≥3-candidate fields (creative recommendations always offer real choice — same rule as h.5; fewer than 3 only on the honest-shortfall exception, with a stated reason; color: core palette with background/secondary_bg/primary/accent/secondary_accent/body_text; typography: CJK + Latin for heading and body with css preview stacks + body_size as the body baseline in px (every canvas) — one fixed value per confirmed delivery_purpose (text 20 / balanced 24 / presentation 32), not a range; each typography candidate must include topic-matched sample_heading / sample_heading_latin / sample_body / sample_body_latin preview text, never a fixed unrelated industry sample; images: image_strategy.candidates rendering × palette from h.5); enumerable icons / formula_policy / generation_mode (recommended id); image_usage as one or more source ids (["ai"], ["ai","provided"], ["web","placeholder"], or ["none"]; none is exclusive). If the recommendation involves several sources, keep the source list structured in recommend.image_usage and write the usage rationale / page-role guidance into image_notes (for example, "封面和章节页用 AI 主视觉，产品页优先用户素材，行业背景页可用网络参考"). Write image_ai_path only when image_usage includes ai. Spot-illustration lean is not a candidate field here: it derives from the locked visual_style's illustration propensity and is expressed only in the recommendation rationale / image_notes, never as a new confirmation field. The still-open page polls, renders Tier 2, and preserves the user's Tier 1 picks. Closed fields (image_ai_path, formula_policy, generation_mode, refine_spec) stay finite; open fields (icons, typography custom text, image notes) expose free-text controls.
Wait for the final confirmation — attach to the already-running page, do not relaunch (same 600000 ms budget):
```
python3 ${SKILL_DIR}/scripts/confirm_ui/server.py <project_path> --wait-only
```
This is the ⛔ BLOCKING completion: returns when the page writes the final result.json (status: confirmed, stage: final, carrying all Tier 1 + Tier 2 fields). On a non-zero exit, re-check result.json once. Confirmed sizes are already px (the system is px-only — no pt anywhere, no conversion): write result.json typography.body_size / sizes into design_spec.md / spec_lock.md / SVG verbatim. generation_mode: "split" / refine_spec: true are explicit user choices.
Close the confirm page (Mandatory cleanup — every path). Shut the server down before leaving Step 4 so it cannot keep holding port 5050 (which Step 6 live preview reuses):
```
python3 ${SKILL_DIR}/scripts/confirm_ui/server.py <project_path> --shutdown
```
Idempotent and required regardless of whether Confirm was clicked: clicking the final Confirm already shuts the page down (then a no-op); the chat-fallback path leaves it running. Run it after reading the confirmation, before Step 5.

Always also print each tier's recommendations + URL in chat as the always-valid fallback. The chat fallback is two-step too: if the page never opens or a wait times out with no fresh result, present Tier 1 in chat → get confirmation → re-derive → present Tier 2 → get confirmation → take those values. Either path converges.

Honoring the confirmation (result.json is authoritative — Mandatory): the confirmed values override your own recommendations when you write design_spec.md / spec_lock.md. A user who changed any field changed it on purpose. In particular, map image_usage to §VIII Acquire Via (its value names differ from §h options — translate). image_usage may be either a legacy single string or a Confirm UI multi-select array; for arrays, apply every selected source. image_notes, when present, is a user-authored image intent note that Strategist must honor while assigning per-page §VIII rows:

`result.json.image_usage`	§VIII `Acquire Via`	h.5 + Step 5 generation
`ai`	`ai` rows	Run h.5 (lock rendering + palette); Step 5 generates
`web`	`web` rows	None
`provided`	`user` rows	None — never generate
`placeholder`	`placeholder` rows	None
`none`	no image rows (§h option A)	None
Legacy custom prose	Infer the intended rows from the prose	Run h.5 only if the prose includes AI

When the confirmed image_usage does not include ai (and no legacy custom prose includes AI), do NOT run h.5, do NOT write ai rows, and do NOT generate images in Step 5 — regardless of what you recommended. none is exclusive: if confirmed, write no §VIII image rows. The same "confirmed value wins" rule applies to every field (color → §III, typography → §IV, etc.).

Small spot illustrations are a Strategist judgment, not a confirmation field. The user chooses image source through image_usage; whether the deck leans into decorative illustrations is anchored by the locked visual_style's illustration propensity (core / supportive / sparse), expressed only in the image_notes rationale — never a new confirmation control. An explicit user request to use or skip illustrations overrides that default either way; image_usage: none still wins (write no illustration rows); and source still comes from image_usage — a core style does not silently generate AI spots when the user did not pick AI. They are ordinary §VIII image rows (Type: Illustration / Illustration Sheet) using normal Acquire Via values. If the plan needs ≥3 same-family AI spot illustrations, use the ai Illustration Sheet + slice workflow by default; do not generate one AI image per spot. Full rule + precedence: references/strategist.md §h. Use them on suitable pages and omit them where they would weaken clarity.

Upstream override → re-derive untouched downstream (Mandatory — chat-fallback / single-pass path). On the two-tier page path this is already handled (Step 3 re-derives Tier 2 from the user's actual anchors). It still applies whenever anchors and realization are confirmed together — the two-step chat fallback collapsed into one bundle, or a legacy single-pass result.json. "Confirmed value wins" governs each field's own value — never recompute a value the user set (a size, canvas, or palette they edited stays verbatim). But a single-p
