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 | $0.00078 | $0.00523 |
| Opus 5 | $0.00039 | $0.00262 |
| Sonnet 5 | $0.00016 | $0.00105 |
| Haiku 4.5 | $0.00008 | $0.00052 |
Grade A, and why
sentiment-engine 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 4d 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.

Data Sources
| Source | Instruments | Update Freq | Data |
|---|---|---|---|
| Myfxbook | 54 forex pairs | Real-time | % long/short retail |
| CFTC COT | 11 (FX, metals, energy) | Weekly (Tue data, Fri release) | Institutional net positions |

Contrarian Signals
Retail sentiment is a contrarian indicator: when >70% of retail is long, consider shorting.
net < -20→ contrarian bullish (retail oversold)net > +20→ contrarian bearish (retail overbought)
COT: Watch for speculative net position extremes and reversals.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
