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 | $0.00008 | $0.00404 |
| Opus 5 | $0.00004 | $0.00202 |
| Sonnet 5 | $0.00002 | $0.00081 |
| Haiku 4.5 | $0.00001 | $0.00040 |
Grade A, and why
check 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 yesterday.
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.

Version
- Check all [project_files] version numbers
- Use the version stated in the
VERSIONfile in the project root as a reference. - Make sure that all targets are consistent with it, including the version in the badges.
- Some files do not have badges, just the version in the text. Make sure those are consistent as well.
- If a file has no version, leave it as it is
Consistency Checking
- Check all target files for consistency and completeness
- Check the numbering of all items and the item count in AI4L.md
Reporting
- If there are any inconsistencies, report them and ask the user if you should fix them.
- Report what was fixed (if anything).
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.

check is a skill published in the GitHub repository forever-healthy/AI4L (38 stars, last pushed 10d ago), licensed MIT. It adds 8 tokens to every session and 404 once invoked, about $0.0000 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 2026-09-04.

health
Personal health knowledge graph — local-first ingest of Garmin (Apple Health, Whoop, Oura, CGM in v2+) traces into SQLite, projected to Obsidian daily-note frontmatter, synthesized into validated longevity-proxy metrics (HRV-CV, CTL/ATL/TSB, VO2max arc). Hex architecture so new sources drop in as adapters. NOT a…
Longevity Protocol
Assembles an evidence-tiered weekly longevity routine across the four pillars with the strongest healthspan data - sleep, zone 2 aerobic work, strength training, and dietary pattern - plus stress and connection, delivered as a filled weekly template with honest evidence labels. Use when someone asks "build me a…
Sleep Optimizer
Builds a personalized sleep protocol - a fixed wake time held within 30 minutes daily, a chronotype-aligned sleep window, a light-exposure plan, environment settings, evening input rules, and a scripted wind-down routine - from a baseline assessment. Use when someone says "I can't fall asleep", "I wake up at 3am every…
