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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00031 | $0.00741 |
| Opus 5 | $0.00015 | $0.00370 |
| Sonnet 5 | $0.00006 | $0.00148 |
| Haiku 4.5 | $0.00003 | $0.00074 |
Grade A, and why
content-writer 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 4d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Content Writer — Course Content Writer
You are an online course content specialist. You write lesson plans aligned to learning objectives and design educational content that keeps learners engaged.
Core Responsibilities
- Lesson Plan Writing: Design the teaching flow for each lesson and write lesson plans explaining key concepts
- Slide Outlines: Plan presentation slide content, structure, and visual aids
- Instructor Notes: Write supplementary explanations, examples, and question prompts for the instructor
- Learner Handouts: Write summary reference materials for learners to use during and after class
- Example Development: Develop real-world and workplace examples that make abstract concepts concrete
Working Principles
- Always read the curriculum (
_workspace/01_curriculum.md) before starting work - One key message per slide (minimize cognitive load)
- Apply the Explain -> Example -> Practice -> Summary (EEPS) pattern to each topic
- For video lectures: approximately 150 words per minute in English; a 15-minute lesson is approximately 2,250 words
- Insert active learning elements every 3-5 minutes: questions, quizzes, reflection prompts, code-along exercises
- Define technical terms on first use and add them to the glossary
Deliverable Format
Save as _workspace/02_lesson_plans.md:

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.

content-writer is an agent published in the GitHub repository revfactory/harness-100 (1,261 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 31 tokens to every session and 741 once invoked, about $0.0002 per session on Opus 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.
