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 | $0.00152 | $0.02445 |
| Opus 5 | $0.00076 | $0.01222 |
| Sonnet 5 | $0.00030 | $0.00489 |
| Haiku 4.5 | $0.00015 | $0.00245 |
Grade A, and why
pptx 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 9d 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 — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PPTX Pro 2.0 — Fast Path
Core principle
Generate a polished, professional .pptx in 6–10 minutes by following a single five-step fast path:
- Gather material — collect the topic, audience, deck length, and any user-supplied source content.
- Ensure environment — verify Python +
python-pptx; install if missing. - Write generator — produce a single
generate.pyscript with inline overflow safeguards. - Execute & self-correct — run, fix any P0 issues in place, rerun.
- Deliver — output the
.pptxto the current working directory with a one-paragraph QA note.
This skill uses Python + python-pptx as the unified engine for all PPTX operations. Quality bars stay the same; the delivery path is faster and more predictable.
When to use
Use this skill for any task involving .pptx files:
- From scratch generation — follow the five-step fast path in this file.
- Editing an existing .pptx — follow the three-step path in
references/editing.md(read structure → write modify script → markitdown verify). Same python-pptx engine, no XML unpacking. - Read-only inspection / text extraction — run
python -m markitdown deck.pptxdirectly, or use the structured-read snippet at the top ofreferences/editing.md.
Step 1 — Gather material
Ask only what is genuinely missing. Do not run mandatory multi-round clarification. The minimum context needed is:
- Topic — what the deck is about.
- Audience and tone — executive, technical, sales, training, internal review.
- Length — slide count target, default 6–8.
- Source content — paste, file path, or "use public knowledge."
If the user already gave clear instructions, skip the question round and proceed.
Step 2 — Ensure environment
Run probes. If they succeed, skip install:
python -c "import pptx; print(pptx.__version__)"
python -m markitdown --help >NUL 2>&1
If they fail:
python -m pip install --quiet python-pptx "markitdown[pptx]"
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.
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.

pptx is a skill published in the GitHub repository XMZF-vAI/clerkbox (7 stars, last pushed 2d ago), licensed Apache-2.0. It adds 152 tokens to every session and 2,445 once invoked, about $0.0008 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.
