## What it does

The skill searches ChEBI by text, fetches a compound record by its identifier, and follows parent or child links in the ontology. It uses `es_search/` for text lookup and `compound/<CHEBI:id>/` for a targeted record. Structure metadata is also within scope. By default, the script’s JSON response is turned into a short Markdown summary.

Every ChEBI request goes through `scripts/rest_request.py`. The script reads a JSON object from stdin; `base_url` and `path` are required, and the service address is `https://www.ebi.ac.uk`. Ask for raw JSON when you need machine-readable output. The input format also supports saving a raw response with `save_raw` and `raw_output_path`.

The skill supports Codex and ChatGPT; the installation command below targets Codex. Requests run through the included script, so the skill relies on `scripts/rest_request.py` to contact ChEBI.

## Install

### Codex (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill chebi-skill -a codex

## When to use it
- find a chemical by a text query
- fetch a compound record by ChEBI identifier
- inspect child terms in the ontology
- trace parent terms for a compound
- retrieve chemical structure metadata

## Example prompts
- Look up caffeine in ChEBI and summarize the result.
- Fetch the ChEBI record for `CHEBI:27732` and give me its key details.
- Show the ontology children of `CHEBI:27732`.
