deckforge-export

A guide for adding or repairing exports in web-based slide applications, especially PowerPoint downloads and other portable formats.

In plain words
What is it for?
Use it to add or audit PPTX, PDF, PNG, SVG, or portable-package exports, including preflight checks, media, text, links, notes, and export tests.
Why use it?
It helps preserve slide content and visual fidelity while checking whether exported files are structurally valid and usable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deckforge-export scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Skill: deckforge-export

Add or repair export capabilities for a DeckForge-compatible or custom web slide application without redesigning the entire product.

When to use

  • User wants to add PowerPoint download to an existing deck
  • User wants to fix export issues
  • User wants to add multiple export formats
  • Agent is auditing export readiness
  • User needs PPTX export with preflight checks

Supported tasks

  • Add PPTX export (hybrid mode; fidelity-first by default)
  • Add the fidelity layer: per-block representation, content-parity gate, fidelity report
  • Add deterministic SVG diagram export and structured SVG snapshot fallback
  • Add real OOXML structural verification (slides, text survival, media rels, notes, links)
  • Add export preflight system
  • Add PDF/PNG/portable package export
  • Add block export registry
  • Audit PPTX editability
  • Add golden export fixtures
  • Repair font and asset portability

Required files

  • ../deckforge/starter-components/export/export-types.ts — core contracts
  • ../deckforge/starter-components/export/pptx/ — PptxGenJS adapter, block exporters, and structural verifier
  • ../deckforge/starter-components/export/fidelity/ — content-parity, representation planner, fidelity report, SVG generators
  • ../deckforge/starter-components/export/export-preflight.ts — preflight engine
  • ../deckforge/starter-components/export/export-dialog.tsx — Export Center UI

Workflow

  1. Inspect project for existing export code
  2. Detect DeckProject schema version
  3. Select export modes and capabilities
  4. Add export types and contracts
  5. Implement adapter and block exporters
  6. Add preflight system
  7. Add Export Center UI
  8. Run export validation
  9. Report coverage and limitations

Quality gates

  • Export creates valid .pptx archive
  • Text remains editable in hybrid mode
  • Preflight runs before export
  • Every visible block has a representation (native, SVG diagram, or snapshot); none are silently omitted
  • Diagrams are exported as complete visuals, never as node/edge count summaries
  • Content-parity gate passes (100% meaningful content recall) before the file can be downloaded
  • OOXML structural verification passes before the export is reported successful
  • Fidelity score is accurate

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

deckforge-export is a skill published in the GitHub repository tph-kds/deckforge (4 stars, last pushed 16d ago), licensed MIT. It adds 58 tokens to every session and 566 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
