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 | $0.00163 | $0.01038 |
| Opus 5 | $0.00081 | $0.00519 |
| Sonnet 5 | $0.00033 | $0.00208 |
| Haiku 4.5 | $0.00016 | $0.00104 |
Grade A, and why
options 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Options — strategy framework
A framework for thinking about and constructing option positions. Based on McMillan's Options as a Strategic Investment (5e), Natenberg's Option Volatility & Pricing, and a handful of practitioner sources cited in the reference files.
Scope
This skill is the strategy layer:
- Which structure fits which view (direction × magnitude × volatility × time)
- How to size and stop
- How to read Greeks
- When to roll / close / let expire
- Common spread mechanics and break-evens
- Predictive indicators (put-call ratio, VIX, skew)
For live option data (chains, strikes, Greeks via IB) — use the
ib-connector skill. Don't duplicate that logic here.
Workflow
When the user brings an options question:
- Identify what they're actually asking. Strategy selection? Risk/sizing? Greek interpretation? Roll decision? Assignment handling? Each goes to a different reference.
- Check regime — implied vol level (vs realized, vs history), skew direction, term structure. A sell-premium thesis only works in one regime; a buy-vol thesis only in another. (Pull realized vol from the underlying's price history; compare to current IV before committing.)
- Pick structure with explicit reasoning about max gain / max loss / break-even / margin requirement / commission drag.
- Size by Kelly fraction × your conviction tier, not by max-loss
tolerance. See
references/formulas-and-spreads.md(Kelly section). - Pre-mortem: what does the position look like at -50% of remaining credit? At +50%? At 21 DTE? What's the assignment risk if assigned tonight? Don't enter without answers.
When to consult which reference
| User is asking about | Open this reference |
|---|---|
| Margin, assignment, roll mechanics, McMillan's 10 rules | references/execution-and-philosophy.md |
| Intrinsic/extrinsic, break-even formulas, Kelly sizing, intermarket spreads, collar tables | references/formulas-and-spreads.md |
| Put-call ratio, VIX interpretation, seasonal patterns, term-structure reading | references/predictive-indicators.md |
| Breadth oscillator, TICKI, post-expiration reversal, systematic entry signals | references/trading-systems.md |
What ships with it
4 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.

options is a skill published in the GitHub repository oh-rid/claude-code-plugin-ib (5 stars, last pushed 3mo ago), licensed MIT. It adds 163 tokens to every session and 1,038 once invoked, about $0.0008 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 2026-08-31.
