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 B, and why

paperbanana-slide-deck scanned grade B with 1 finding 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 286 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PaperBanana Slide Deck

End-to-end slide deck creation and modification. Two deck modes (image and editable, chosen explicitly in Phase M), and within image mode two workflows: creating new decks from scratch, and regenerating existing decks after prompt edits.

Image pipeline: Content → Style Selection → Outline → Prompts → Image Generation → PPTX Merge Editable pipeline: Content → slide-spec.json (native text/table/chart/shape/line/group) → validate → build PPTX → render previews → Critic review → revise spec → rebuild

Phase M: Deck mode selection

Record exactly one line in deck-mode.txt: image or editable.

  • Use editable when the user asks to edit text/tables/charts/connectors in PowerPoint or explicitly asks for editable PPTX.
  • Use image when the user asks for generated full-slide artwork or preserves the existing PaperBanana image workflow.
  • If both are plausible, ask before generation. Do not infer from file presence.
  • editable requires slide-spec.json; a missing or invalid spec is an error. Never fall back to image mode while claiming editability.

Mode Detection (image mode)

Within image mode, determine the workflow by checking the target directory:

Condition Mode Start Phase
Target dir missing OR no outline.md New Phase R (full RDIV)
Target dir has outline.md + prompts/ Modify Phase I (generate + merge)

In Modify mode, the user has already edited prompts or outline externally. Skip directly to Phase I.

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.
