What is gammarips-options-flow?

A workflow for analysing GammaRips, an options-flow data service that provides research data about potentially tradable US stock-option contracts.

Use it to review unusual options activity, compare opportunity and risk measures, study historical outcomes, and form your own contract and exit plan.

It provides a structured way to examine the service's daily pool, historical price-movement measures, and outcome labels without treating the data as a trading recommendation.

Token cost

What it costs to keep this loaded

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	$0.00091	$0.01026
Opus 5.5	$0.00036	$0.00410

Security

Grade A, and why

gammarips-options-flow 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 1mo 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.

GammaRips options-flow data

GammaRips gives your agent a ready, high-quality options universe every US trading night, plus the history to plan the exit. Each night the engine ranks about 3,500 optionable US stocks, keeps the 100 most liquid, keeps the bullish names, and selects one out-of-the-money call in each on contract liquidity. The pool holds roughly 40 to 50 contracts with deep books: median open interest 4,664 and median session volume 1,039, against 906 and 232 before the liquidity rule. In a 60-day study, no-fill at the 10:00 ET entry fell from 40.5% to 6.1%.

What to do

When the user asks for a trade, build a plan with them. Use the gammarips-trade-plan skill if it is available. If not, follow the plan steps in get_playbook(name="start-here"). Give 1 to 3 candidates with entry, target, stop, maximum loss, and size, or a reasoned no-trade.
When the user asks for a morning read, use the gammarips-morning-brief skill if it is available.
When the user asks where to exit, use the gammarips-exit-lab skill if it is available, or get_playbook(name="exit-lab").

Rules

GammaRips has no pick endpoint. Your agent builds the plan with the user. Label it as your analysis of GammaRips data. The user decides.
Do not state an expected return or a win rate, and do not claim the pool returns more than other contracts. Quality claims are about execution: liquidity, open interest, volume, and fills.
Do not answer a trade request with pool-wide averages. They describe every contract under one fixed rule, not the plan you build.
query_outcomes views positions and performance hold the history of a retired engine test. Do not use them to judge the pool.
Point-in-time discipline. Features are as of the overnight scan. Outcome labels and surfaces arrive after the trade window closes. Never treat a label or a surface as a live signal for the same day. If you are not sure when a field was knowable, call get_playbook(name="schema") or get_playbook(field="<name>").
GammaRips is read-only. It cannot place, change, or cancel an order.
End each plan or summary with: paper-traded research data, educational only, not investment advice.

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.
