PPTX Generator

Contract

[KNOWN|USER] pptx-generator is the sole general PPT/PPTX workflow owner. OfficeCLI is an internal non-routable tool adapter, not another Skill or lifecycle owner. Source: accepted change pptx-workspace-officecli-integration, decision m0020.

[FRAME] This skill treats a presentation as a communication artifact first and a collection of decorated slides second. It is workspace-first: authored sources, generated artifacts, and verification evidence stay separated and hash-linked.

Use one of three branches:

Near misses:

• Return HTML/SVG design generation, PDF-only output, and document/spreadsheet artifacts to ROSE for the appropriate artifact owner.
• For outline coaching or slide critique with no PPTX artifact, provide bounded advice directly rather than manufacturing a file workflow.
• Do not silently convert a browser-rendered deck into a PPTX; editable-slide output is a distinct deliverable.

Capability Boundary

• Required: artifact.transform for PPTX/package generation or editing.
• Optional: repo.read for local source decks and supporting content; artifact.store for the final user-visible file.
• If a required capability is missing, return blocked with the missing operation and do not claim a usable PPTX.
• If visual rendering or inspection is unavailable, return Unverified for layout, clipping, font substitution, and image-crop claims; text extraction alone is not visual QA.
• Installing a runtime or dependency, reading an external directory, fetching network assets, or writing outside the owning repository retains its separate ROSE approval gate.

Common Workflow

1. Initialize the profile workspace

[FRAME] Choose from-scratch, template-edit, or inspect, then follow references/workspace.md. Capture audience, setting, purpose, language, duration/count, source/template, output path, editability, and material blockers in the profile-owned sources described by references/intake-and-blockers.md.

[FRAME] Completion criterion: the workspace profile and artifact contract are explicit; required sources exist or are typed blockers.

2. Establish the canonical plan

[KNOWN|USER] <deck-name>-per-slide-content-plan.md is the sole semantic source for slide count, order, title, Layout, and Content. Source: accepted change pptx-workspace-officecli-integration, decision m0020.

[FRAME] Follow references/content-planning.md. Every slide uses exact ## Slide NN:, one stable <!-- slide-id: lower-kebab -->, exactly one ### 1. Layout, and exactly one ### 2. Content. Keep page takeaways and source/status annotations inside Content.

[FRAME] Compile with scripts/compile_plan.py; outline.json is generated-only. Normal compilation never edits Markdown. Use --initialize-ids only for an explicit migration that inserts missing IDs without changing semantic text.

[FRAME] Completion criterion: the deterministic outline exactly matches current normalized Markdown and has continuous ordinals plus unique stable IDs.

3. Establish design and fonts

[FRAME] When a template exists, derive its grammar instead of imposing defaults. Otherwise use references/design-system.md, references/human-design-playbook.md, and references/design-contract.md. Record content area, hierarchy, palette roles, shape/image/chart language, and navigation in the design contract without duplicating slide copy.

[FRAME] For template-edit, first confirm every visual reference's role, allowed uses, fidelity mode, path, and hash. Before mapping content, run scripts/profile_template.py and require a current template-profile.json that preserves shape→paragraph→run raw/inherited/effective typography, palette usage, native layout IDs, capacity, alignment, spacing, and image-frame evidence. A role summary never overrides a run-level exception.

[FRAME] Follow references/font-policy.md. font-contract.json records intent; font-environment.json separately records registration, mounted files, and renderer-visible families. Required fonts must be verified separately in build and render environments; missing/unknown required fonts return need-user. Unknown target-player availability remains named Unverified.

[FRAME] For from-scratch work, render and actually review a representative Style Proof before full build. A style lock binds current design/proof/review hashes; any bound change invalidates it.

[FRAME] Use the style-proof build kind and stable-ID render selection before creating the lock; the default full from-scratch build fails closed when the lock is missing or stale. Generate the hash-bound font audit from the current contract evidence before relying on font readiness.

[FRAME] Completion criterion: current contracts define one implementable visual grammar, required fonts are evidenced, and applicable Style Proof evidence is current.

4. Compute workspace readiness

[FRAME] Run scripts/report_workspace_readiness.py. workspace.json records identity/configuration and never supplies manual completion truth. Resolve typed blocked or needs_attention results before building.

[FRAME] Only registered renderer kinds and contained workspace-relative entrypoints are allowed. Arbitrary command strings, absolute paths, .., and escaped symlinks are blocked. Readiness fingerprints renderer source and authored inputs.

[FRAME] Completion criterion: readiness is ready for the selected branch and all named Unverified limits remain explicit.

5. Implement with the selected branch

• Inspect: extract text and package metadata; render slides when making visual claims.
• Template-preserving edit: follow references/editing.md.
• From scratch: use the registered renderer and technical patterns in references/pptxgenjs.md.

[FRAME] Every supported editable text-bearing shape in a final from-scratch or template-edit PPTX uses shape-to-fit-text. Apply it after paragraph/run formatting, then reread the final geometry. Unsupported, locked, unreadable, or non-recalculated objects are blockers; AutoFit never waives overlap, boundary, single-line, font-size, spacing, alignment, or visual checks.

[FRAME] src/ reads current outline/design/font/assets and implements layouts; it never stores a second copy of page titles or content. Keep custom slide builders keyed by stable slide ID and include all renderer source in the build fingerprint.

[FRAME] OfficeCLI use stays behind references/officecli-adapter.md. The AILI installer owns installation and recovery; this Skill retains only PPTX-specific probe/build/render use. Use installed-version help as syntax authority; do not run npm or install/load OfficeCLI Skills, MCP, PATH integration, or another presentation owner.

[FRAME] Completion criterion: all canonical slides exist, content is mapped once from outline, no placeholder survives, and the build report binds current source/renderer/outline/final-PPTX hashes.

6. Verify content, visuals, and delivery

[FRAME] Follow references/pitfalls.md, references/visual-review.md, and references/delivery-readiness.md:

1. [FRAME] validate/repack the current final PPTX and bind validation to its hash;
2. [FRAME] render every slide and a contact sheet, then hash each artifact;
3. [FRAME] run scripts/report_layout_preflight.py against the current final PPTX, post-AutoFit geometry, font audit, image-fit evidence, and individually dispositioned OfficeCLI issues; any blocking or unknown item fails closed;
4. [FRAME] read the actual images and record reviewer, exact PPTX/render hashes, exact slide IDs, per-page checks, concrete observations, findings, finding dispositions, and overall disposition;
5. [FRAME] for template-edit, obtain user confirmation of the current baseline/current proof hash before a full build; confirmation never waives final per-page review;
6. [FRAME] repair at source and rebuild every invalidated downstream step;
7. [FRAME] run scripts/report_delivery_readiness.py; missing or stale evidence fails closed.

[FRAME] Completion criterion: the current plan→outline→build→PPTX→render→visual-review hash chain is ready; unsupported target-viewer, font, animation, or visual claims remain Unverified.

Reference Map

Hard Boundaries

• Preserve the original file unless replacement was explicitly requested; write an edited copy by default.
• Do not rebuild a supplied template from scratch merely because generation is easier.
• Do not invent data, citations, logos, customer names, or source claims to fill a slide.
• Do not begin slide production before a required per-slide content plan exists and its material omissions, claims, or structure decisions are resolved.
• Do not edit outline.json as a semantic source or copy slide meaning into renderer source.
• Do not accept unregistered renderer kinds, arbitrary command strings, or workspace-escaping paths.
• Do not hide PPTX corruption or layout defects by shipping only screenshots or a PDF.
• Do not treat a render, issue scan, file-existence check, or reviewer-free record as visual completion.
• Do not silently substitute a required build/render font or claim an unknown target font environment is verified.
• Do not force a page-number badge, palette, font, gradient, animation, or decorative motif when the brief or controlling template does not use it.
• Do not recurse, invoke another process skill, or delegate. Return any routing, research, capability, approval, or independent-work need to ROSE.

Terminal Outcomes

• complete: the requested PPTX work is produced and claim-matched verification is current.
• need-user: one material audience, content, template, output, style, required-font, or fidelity decision is unresolved.
• need-evidence: required source content or visual/package evidence is unavailable.
• material-delta: implementation reveals a new dependency, public artifact contract, permission, or verification-strategy change.
• blocked: required capability/approval is missing, workspace/delivery readiness fails closed, renderer/path policy is violated, or the PPTX remains corrupt.
• Unverified: the file exists but one or more claimed visual behaviors could not be freshly inspected.
