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 | $0.00000 | $0.00462 |
| Opus 5 | $0.00000 | $0.00231 |
| Sonnet 5 | $0.00000 | $0.00092 |
| Haiku 4.5 | $0.00000 | $0.00046 |
Grade A, and why
platform-awareness 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.
This is a copy
100% identical to platform-awareness — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
PLATFORM AWARENESS SYSTEM
TL;DR: This system detects the operating system, path format, and shell environment, then adapts commands accordingly to ensure cross-platform compatibility.

📋 PLATFORM DETECTION IMPLEMENTATION
For reliable platform detection:
## Platform Detection Results
Operating System: [Windows/macOS/Linux]
Path Separator: [\ or /]
Shell Environment: [PowerShell/Bash/Zsh/Cmd]
Command Adaptation: [Required/Not Required]
Adapting commands for [detected platform]...
🔍 PATH FORMAT CONVERSION
When converting paths between formats:

participant Input as Path Input
participant Detector as Format Detector
participant Converter as Format Converter
participant Output as Adapted Path
Input->>Detector: Raw Path
Detector->>Detector: Detect Current Format

Converter->>Output: Platform-Specific Path
📝 PLATFORM VERIFICATION CHECKLIST
✓ PLATFORM VERIFICATION
- Operating system correctly identified? [YES/NO]
- Path separator format detected? [YES/NO]
- Shell environment identified? [YES/NO]
- Command set adapted appropriately? [YES/NO]
- Path format handling configured? [YES/NO]
→ If all YES: Platform adaptation complete
→ If any NO: Run additional detection steps
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.

platform-awareness is a cursor rule published in the GitHub repository Angry-Robot-Deals/ace-mcp (4 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 462 tokens. A static security scan graded it A with 0 findings. It is 100% identical to platform-awareness, differing in 0 lines, and is treated as a copy.
