# UKBAnalytica Skill Pack (`UKBAnalytica_skills`)

Agent-runtime-agnostic skill bundle for the [`UKBAnalytica`](https://github.com/Hinna0818/UKBAnalytica)
R package. The pack works with any agent stack that supports a "skill" / "tool
description" loaded from YAML front-matter + Markdown (Claude Code skills,
OpenAI Assistants instructions / function-tool descriptions, custom RAG-driven
agents, etc.).

The pack lives at `inst/skills/UKBAnalytica_skills/` in the repository root.
Load it via `file.path(getwd(), "inst/skills/UKBAnalytica_skills")` or see
[INSTALL.md](INSTALL.md) for per-runtime loader snippets.

## Charter (read first)

All skills in this pack enforce the following non-negotiable rules:

1. **Script-generation boundary.** These skills help a local agent generate
   scripts, analysis plans, package-usage guidance, and manuscript text from
   aggregate outputs. They are not permission for an agent to read or process
   real UK Biobank RAP participant-level data.
2. **RAP-only execution.** Scripts that touch real UK Biobank data must be run
   by the user inside the approved UK Biobank Research Analysis Platform (RAP),
   typically `RAP JupyterLab → Terminal → R`.
3. **No real rows in agent context.** Do not give the agent participant-level
   files, R objects, screenshots, logs, tracebacks, row samples, `head(data)`,
   `eid`, exact dates, raw RAP fields, per-row predictions, or row-level SHAP
   matrices. This applies even when identifiers have been removed.
4. **Aggregate outputs only.** The user may share aggregate summaries with the
   agent, including participant-flow counts, baseline tables, regression
   summaries, model metrics, enrichment results, and rendered figures.
5. **Schema-only prompts.** The user may describe column names, variable roles,
   and intended analyses. The agent uses synthetic toy data for smoke tests and
   writes final scripts for RAP execution.
6. **Large extracts go async.** When the requested field count is large,
   skills route the user through `rap_submit_extract()` (DNAnexus
   `table-exporter`) rather than pulling everything into the R session.
7. **`UKBAnalytica` is the sole executor.** Skills wrap real exported
   functions only — every function name in a skill must be present in
   `NAMESPACE`.
8. **No journal-brand styling.** Plotting guidance uses neutral palette names
   (`ukbsci_clinical`, `ukbsci_diverging`, `ukbsci_sequential`) and avoids
   referencing specific top-tier journal brands.

## Provider compatibility

| Runtime | Loader pattern |
|---------|----------------|
| Claude Code skills | Drop `inst/skills/UKBAnalytica_skills/` into `~/.claude/skills/` (or workspace `.claude/skills/`); each `ukbsci-*/SKILL.md` is auto-discovered via its `name` + `description` front-matter. |
| OpenAI Assistants / Responses | Concatenate `SKILL.md` files into the assistant `instructions` (or attach as file-search documents); use the `description` field as the routing summary. |
| LangChain / LlamaIndex agents | Treat each `ukbsci-*/` directory as a Tool whose docstring = `description`, whose body = `SKILL.md` + `references/*.md`. |
| Generic JSON tool list | Read each `SKILL.md` YAML header → `{name, description}`; load body lazily when the agent decides to invoke. |

The front-matter is intentionally minimal (`name`, `description`) so it parses
identically across providers. No provider-specific keys are used. Regardless
of provider, these skills must not be used to send real participant-level RAP
data to the agent.

## Trigger-word routing table

Every `SKILL.md` description ends with the phrase **"UK Biobank RAP" or "UKBAnalytica"**
to keep the router from confusing these skills with generic R / statistics
skills. Triggers below are written into the `description` field verbatim.
