ib-find-short-roll

ib-find-short-roll is a skill for Claude Code from staskh/trading_skills. It costs 55 tokens per session (1,215 once invoked), scanned A, original, MIT.

An Interactive Brokers analysis tool for changing existing short option positions to later or different contracts, or for finding short options to open against owned stock. A covered call or put is an option position opened against another position to manage income or risk.

In plain words
What is it for?
Use it to explore rolls for short options, find covered calls or puts against long stock, and compare possible strikes, expirations, or option types.
Why use it?
It helps compare possible adjustments using current broker data instead of searching contracts manually. It supports both managing existing short positions and finding candidates for new covered positions.

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.

Security

Grade A, and why

ib-find-short-roll 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/roll.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IB Find Short Roll

Analyze roll options for short positions or find best short options to open against long stock using real-time data from Interactive Brokers.

IB Connection

TWS or IB Gateway must be running locally with API enabled:

  • Paper trading — port 7497
  • Live trading — port 7496
  • IB_PORT env var — default port when --port is omitted (e.g. IB_PORT=4001 for a Gateway container). Precedence: --port flag > IB_PORT > built-in default. Set it in the shell or a .env file.

Port fallback: If the configured port fails, automatically retry on the other port. If the retry succeeds, save to memory which account type worked (live/paper) and reuse it for all IB skill calls in this and future sessions — until the user explicitly asks for the other account. If both ports fail, ask the user to verify that TWS or IB Gateway is running with API access enabled.

Instructions

Step 1: Gather Data

Note: If uv is not installed or pyproject.toml is not found, replace uv run python with python in all commands below.

uv run python scripts/roll.py SYMBOL [--strike STRIKE] [--expiry YYYYMMDD] [--right C|P] [--port PORT] [--account ACCOUNT] [--iv-multiplier N]

The script returns JSON to stdout with all position and candidate data.

Step 2: Format Report

Read templates/markdown-template.md for formatting instructions. Generate a markdown report from the JSON data and save to sandbox/.

Step 3: Report Results

Present key findings to the user: recommended position, credit/debit, and the saved report path.

Behavior

  1. If short option position exists (mode: "roll"): Analyzes roll candidates to different expirations/strikes
  2. If long option position exists (mode: "spread"): Finds best short call/put to create a vertical spread
  3. If long stock exists (mode: "new_short"): Finds best covered call (or protective put) to open
  4. If none of the above: Returns error (use --strike/--expiry to specify manually)

What ships with it

2 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.

Changes

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.
