Use the IOBRcausal Skill

The Skill lets an AI host turn your task into the package’s public request. Install it using the installation guide, then start a new Codex or Claude Code session.

Give the task and the files

In Codex, use $iobrcausal; in Claude Code, use /iobrcausal. For example:

$iobrcausal Inspect the expression matrix and clinical table in /path/to/project.
Check sample IDs and gene coverage, then plan a pathway-first Response analysis.
Use the baseline covariates in the supplied codebook.

For an already agreed execution task:

$iobrcausal Run the agreed pathway-first analysis in /path/to/project.
Keep the approved endpoint, covariates, seed and testing family.
Deliver the complete endpoint tables, reading guide and figures.

For saved results:

$iobrcausal Read /path/to/results and explain the requested feature's estimates.
Draw a forest plot from the saved numbers and include the source table.

Supply endpoint coding and units, sample IDs, matrix orientation and the actual adjustment rationale. The host should inspect material gaps rather than infer clinical definitions from column names.

One execution entry

The Skill uses iobrcausal(request = ..., inputs = ...) with an explicit complete-workflow request. Structured R requests do not need an LLM API. Direct estimator chapters are advanced R instruction; they are separate ways to ask a statistical question, not extra steps to run after a completed workflow.

The host integration uses the model access already supplied by that host. Standalone natural-language calls from an independent R session need a configured provider. Keep credentials outside scripts and reports.

Optional package-managed integration

If the package CLI is available:

iobrcausal agent install
iobrcausal agent status
iobrcausal start

This is an alternative integration route with package-managed client assets. Check actual host loading as well as installation status. The standard npx command can install only the Skill documents before R is available. Use troubleshooting if the launcher is not on PATH.
