Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.03499 |
| Opus 5 | $0.00028 | $0.01750 |
| Sonnet 5 | $0.00011 | $0.00700 |
| Haiku 4.5 | $0.00006 | $0.00350 |
Grade A, and why
pptx-generate-template-skill 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 4d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 236 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What I do
I am the pptx-generate-template-skill (US-3.1). I take any .pptx, run the full extraction pipeline, and return a templated PPTX — the original file plus an embedded ppt/template_schema.json that describes every layout, component, font, and theme color. The embedded JSON "travels with the file" so it can be queried or reused later.
I orchestrate the existing schema_extractor engine end-to-end:
extract → validate → (title confirm) → (confirmation table) → embed → return templated PPTX + summary
I do not fill templates, generate slides, or build decks. Those are pptx-generate-slide-skill and pptx-subagent. I only extract and package a template definition.
When to use me
Use this skill when the user wants to:
- "extract the template from this PPTX"
- "generate a template" / "make a templated PPTX"
- "what layouts / components / fonts does this template have?"
- "fingerprint this deck" / "describe this template's structure"
- produce a reusable, self-describing
.pptxfor later slide generation
Do NOT use me for:
- Filling a template with content →
pptx-generate-slide-skill - Extending a template's layouts (cloning) →
pptx-template-modifier-skill - Generating a presentation / slides →
pptx-subagent
Engine
The engine lives in the shared _common/scripts package (PLAN-GIT-72). I call its functions directly (so I can inspect the extracted schema mid-pipeline for the title-confirmation and confirmation-table steps):
| Function | Purpose |
|---|---|
extract_schema(path) -> dict |
Read the PPTX, emit the proposed-schema JSON (US-1.1–1.5, US-2.1 header/footer detection, US-3.5 master text defaults). |
validate_template_schema(dict) -> ValidationResult |
Structural validation (incl. title_source enum, MAJOR-2). |
needs_header_footer_prompt(schema) -> bool |
True when the template has neither header nor footer (US-2.1 AC2). |
inject_default_header_zone(schema) |
Inject a default header zone into the schema metadata (US-2.1 AC3, schema-only). |
embed_schema(pptx, schema, out) -> EmbeddedSchemaResult |
Write ppt/template_schema.json into a PPTX copy (US-1.5). |
build_extraction_summary(dict) -> str |
Human-readable summary, incl. master text defaults (US-3.3 AC2). |
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.
