Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00066 | $0.03273 |
| Opus 5.5 | $0.00026 | $0.01309 |
| Sonnet 5.5 | $0.00013 | $0.00655 |
| Haiku 4.5 | $0.00007 | $0.00327 |
Grade A, and why
build-cfa-deck 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 1mo 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.

Build CFA Deck
Generate a complete, on-brand Chick-fil-A PowerPoint presentation from a topic prompt. Uses the CFA "Support Now" PPTX template (64 layouts, 194 SVG icons, embedded Apercu fonts), extracted brand assets, and comprehensive brand guidelines.

Prerequisites
python-pptxinstalled (pip install python-pptx --break-system-packages)- python-pptx 1.0.2 is the verified version. Slide removal (
references/cfa-deck-helpers.md) relies onPresentation.slides._sldIdLstandPresentationPart.drop_rel()._sldIdLstis a private (leading-underscore) attribute with no documented public equivalent — if a different python-pptx version is installed, re-verify both calls against a scratch copy of the template before trusting the build script (see the "Removing Sample Slides" section of the helpers reference for what to check). - CFA PPTX template at
${CFA_ASSETS_DIR:-~/dev/stratfield/slide-generator/examples}/CFA PPT Template2.pptx - Brand guidelines at
${CFA_ASSETS_DIR:-~/dev/stratfield/slide-generator/examples}/cfa-brand-guidelines-for-ppt.md - Brand assets extracted to
${CFA_ASSETS_DIR:-~/dev/stratfield/slide-generator/examples}/cfa-brand-assets/ - All assets must exist before proceeding. If the Pre-loaded Context preflights above report MISSING for any asset, stop immediately and ask the user to either set
CFA_ASSETS_DIRto the correct path or run the asset extraction first.
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.

build-cfa-deck is a skill published in the GitHub repository davistroy/claude-marketplace (5 stars, last pushed 19d ago), licensed MIT. It adds 66 tokens to every session and 3,273 once invoked, about $0.0003 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 2026-09-04.
