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.

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 | $0.00043 | $0.00737 |
| Opus 5.5 | $0.00017 | $0.00295 |
| Sonnet 5.5 | $0.00009 | $0.00147 |
| Haiku 4.5 | $0.00004 | $0.00074 |
Grade A, and why
ppt-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 10d 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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PPT Skill
Trigger
Use when the task requires:
- one or more PPT template backgrounds
- a full presentation from idea, outline, or source documents
- slide-image-based presentation rendering
- export delivery as
pdforimage_ppt
First-Use Reminder
On the first use of this skill in a conversation, remind the user that image generation reads
config/image-provider.json in this skill folder, and that it must be filled in before any image can be produced.
If it does not exist, they copy config/image-provider.example.json to it; the filled file is git-ignored and
must not be committed.
Order
- Classify the task.
- Collect missing required fields for that task type.
- Read the required references.
- Produce the planning or generation prompt.
- Generate template backgrounds or slide images.
- Route into the requested export mode.
- Export or bundle artifacts when requested.
Task Types

Required References

Read only the references needed for the current task type.
Plan Contract
For full-presentation generation, every slide must include:
idtitlecontentdescriptionlayoutnote
description is for visual generation, not for audience-facing copy.
Template Contract
- Template generation creates text-free 16:9 background images.
- Templates are style references, not completed slides.
- Template output may include one or more variants when the user asks for options.
Export Contract
Supported delivery modes:
pdfimage_ppt
If the user does not specify an export mode, recommend pdf and image_ppt first.
Image Contract
- Image generation uses
config/image-provider.json. - Template generation and slide generation use the same image config unless the user explicitly defines a split configuration.
- Require
apiKeyandmodel. - Do not ask the user to paste API keys into chat.
- If image generation is requested and config is missing or incomplete, stop and tell the user to fill the config file.

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.

ppt-skill is a skill published in the GitHub repository CodingFeng101/CanvasAnvil (160 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 737 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
