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 5.1 | $0.00056 | $0.00155 |
| Opus 5 | $0.00028 | $0.00077 |
| Sonnet 5 | $0.00011 | $0.00031 |
| Haiku 4.5 | $0.00006 | $0.00015 |
Grade A, and why
lesson 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 5d 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.
What it actually says
Run the workflow in docs/playbooks/lesson.md.
Tracks live in docs/tracks/<slug>/. Tie every lesson to a real thing the user
is building, build new concepts from first principles (check their background in
PROJECT.md), and use escalating hints for exercises — full solutions only after
an attempt. Keep tracks lightweight; defer runaway depth to
docs/learning-debt.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.

lesson is a skill published in the GitHub repository ahamedzoha/atelier (2 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 155 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
