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 | $0.00038 | $0.03693 |
| Opus 5 | $0.00019 | $0.01847 |
| Sonnet 5 | $0.00008 | $0.00739 |
| Haiku 4.5 | $0.00004 | $0.00369 |
Grade A, and why
options-trading 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 11d 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.

Offset System
OpenAlgo uses an intuitive offset system to select strikes relative to ATM:
| Offset | Meaning | Example (NIFTY ATM=26000) |
|---|---|---|
ATM |
At The Money | 26000 |
ITM1 |
1 strike In The Money | CE: 25950, PE: 26050 |
ITM2 |
2 strikes In The Money | CE: 25900, PE: 26100 |
OTM1 |
1 strike Out of The Money | CE: 26050, PE: 25950 |
OTM2 |
2 strikes Out of The Money | CE: 26100, PE: 25900 |
OTM5 |
5 strikes Out of The Money | CE: 26250, PE: 25750 |

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.
