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.

What it costs to keep this loaded
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 | $0.00020 | $0.00463 |
| Opus 5 | $0.00010 | $0.00231 |
| Sonnet 5 | $0.00004 | $0.00093 |
| Haiku 4.5 | $0.00002 | $0.00046 |
Grade A, and why
sleep-optimization 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 8d 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
Sleep Optimization
Optimize sleep quality and duration for health and performance.
Sleep Science Basics
Sleep Cycles (90 min each)
- NREM (75%): Deep restorative sleep — tissue repair, immune function
- REM (25%): Dream sleep — memory consolidation, emotional processing
Optimal Schedule
- 7-9 hours for adults
- Consistent bedtime + wake time (even weekends)
- Wake up at the end of a cycle (multiples of 90 min from bedtime)
Sleep Hygiene Protocol
2 Hours Before Bed
- Dim lights, use warm color temperature
- No screens (or blue light blockers)
- No intense exercise
- No heavy meals, caffeine, or alcohol
- Room temperature: 65-68°F (18-20°C)
- White noise or earplugs if needed
30 Minutes Before Bed
- Wind-down routine (same order every night)
- Read fiction (not work-related)
- Journal to offload racing thoughts
- Stretch or gentle yoga
- Avoid bright bathroom lights
Environment Design
- Complete darkness: Blackout curtains, tape LED lights
- Cool temperature: Cooler room = deeper sleep
- Quiet: Earplugs or white noise machine
- Comfortable bed: Mattress 7-10 years lifespan
- Clean air: Open window or air purifier
Tracking & Adjustment
Use wearable (Oura, Apple Watch, Fitbit) to track:
- Time in bed vs actual sleep
- Deep sleep percentage (>15% ideal)
- HRV trend (higher = better recovery)
- Consistency score
Adjust based on data: if deep sleep low → increase evening wind-down. If latency high → no caffeine after 2pm.
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.

sleep-optimization is a skill published in the GitHub repository cosmicstack-labs/mercury-agent-skills (471 stars, last pushed 17d ago), licensed MIT. It adds 20 tokens to every session and 463 once invoked, about $0.0001 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 2026-09-03.
