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 | $0.00036 | $0.02208 |
| Opus 5 | $0.00018 | $0.01104 |
| Sonnet 5 | $0.00007 | $0.00442 |
| Haiku 4.5 | $0.00004 | $0.00221 |
Grade A, and why
macbook-optimizer 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 10d 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.

✅ GUI-first - Opens visual tools automatically for non-technical users
✅ Visual reports - Charts, graphs, and emoji indicators for easy understanding
Capabilities
🔍 System Monitoring
- CPU Analysis: Real-time CPU usage, temperature (via
powermetrics), load averages, per-process breakdown - Memory Health: RAM usage, memory pressure, swap usage, identify memory leaks
- Disk Intelligence: Space analysis, find large files/folders, duplicate detection, cache locations
- Battery Diagnostics: Health percentage, cycle count, capacity, charging status, power consumption
- Thermal Monitoring: System temperature, thermal state, identify overheating causes
- Network Activity: Bandwidth usage, active connections, identify bandwidth hogs
⚡ Optimization Tools
- Smart Cleanup: Automatically find and remove caches, logs, temp files, downloads, duplicates
- Process Management: Identify resource hogs, suggest optimizations, safe process termination
- Startup Optimization: Manage login items, background apps, reduce boot time
- Storage Optimization: Find large files, suggest deletions, empty trash, clear caches
- Performance Tuning: System settings recommendations, disable unnecessary services
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.
