AuC is a Python framework for running a single AI agent with an asynchronous, pluggable reasoning loop, language-model adapters, permission levels, and observable events. It is used to build coding and conversational agents with tools, security checks, web interfaces, background jobs, evaluations, and isolated execution. The catalogue entries are skills for extending its agent workflow.
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 | $0.00064 | $0.00761 |
| Opus 5 | $0.00032 | $0.00380 |
| Sonnet 5 | $0.00013 | $0.00152 |
| Haiku 4.5 | $0.00006 | $0.00076 |
Grade A, and why
anthropic-theme-factory 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.
This is a copy
92% identical to theme-factory — 32 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Theme Factory Skill
This skill provides a curated collection of professional font and color themes themes, each with carefully selected color palettes and font pairings. Once a theme is chosen, it can be applied to any artifact.
Purpose
To apply consistent, professional styling to presentation slide decks, use this skill. Each theme includes:
- A cohesive color palette with hex codes
- Complementary font pairings for headers and body text
- A distinct visual identity suitable for different contexts and audiences
Usage Instructions
To apply styling to a slide deck or other artifact:
- Show the theme showcase: Display the
theme-showcase.pdffile to allow users to see all available themes visually. Do not make any modifications to it; simply show the file for viewing. - Ask for their choice: Ask which theme to apply to the deck
- Wait for selection: Get explicit confirmation about the chosen theme
- Apply the theme: Once a theme has been chosen, apply the selected theme's colors and fonts to the deck/artifact
Themes Available
The following 10 themes are available, each showcased in theme-showcase.pdf:
- Ocean Depths - Professional and calming maritime theme
- Sunset Boulevard - Warm and vibrant sunset colors
- Forest Canopy - Natural and grounded earth tones
- Modern Minimalist - Clean and contemporary grayscale
- Golden Hour - Rich and warm autumnal palette
- Arctic Frost - Cool and crisp winter-inspired theme
- Desert Rose - Soft and sophisticated dusty tones
- Tech Innovation - Bold and modern tech aesthetic
- Botanical Garden - Fresh and organic garden colors
- Midnight Galaxy - Dramatic and cosmic deep tones
Theme Details
Each theme is defined in the themes/ directory with complete specifications including:
- Cohesive color palette with hex codes
- Complementary font pairings for headers and body text
- Distinct visual identity suitable for different contexts and audiences
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.
