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 | $0.00077 | $0.04255 |
| Opus 5 | $0.00039 | $0.02128 |
| Sonnet 5 | $0.00015 | $0.00851 |
| Haiku 4.5 | $0.00008 | $0.00426 |
Grade A, and why
audiobook-production 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 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.
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.

Audiobook Production
Master ACX-compliant audiobook production using Audible's technical standards and Richard Mayer's multimedia learning principles for engaging, professional audio.
When to Use This Skill
- Producing an audiobook for Audible/ACX distribution
- Creating audio versions of courses or written content
- Setting up narration workflow for long-form content
- Ensuring audio meets professional distribution standards
- Self-producing an audiobook as an author
- Managing audiobook production projects
Methodology Foundation
Source: ACX (Audiobook Creation Exchange) + Richard Mayer (Multimedia Learning)
Core Principle: Professional audiobook production balances technical excellence (meeting strict ACX standards) with engaging delivery (applying learning science principles). As Mayer's research shows: "People learn better from friendly human voice than machine voice" (Voice Principle).
Why This Matters: ACX/Audible rejects audiobooks that don't meet technical specifications, wasting production time and money. Beyond technical compliance, understanding how listeners process audio enables production choices that maximize engagement and retention.
What Claude Does vs What You Decide
| Claude Does | You Decide |
|---|---|
| Structures production workflow | Final creative direction |
| Suggests technical approaches | Equipment and tool choices |
| Creates templates and checklists | Quality standards |
| Identifies best practices | Brand/voice decisions |
| Generates script outlines | Final script approval |
What This Skill Does
- Ensures ACX technical compliance - Specs for bit rate, sample rate, RMS, peaks, and noise floor
- Structures audiobook projects - Chapter organization, credits, retail samples
- Applies learning principles - Pacing, tone, and delivery that aid comprehension
- Manages production workflow - From script to final master
- Handles proofing and QC - Catching errors before submission
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.
