## What it does

A Celigo lookup cache is an in-memory key-value store the integration reads without hitting an external system per record. The skill covers creating one, loading entries and referencing it from import and export mappings. The reference goes through `_lookupCacheId`, and the `extract` JSON path pulls a single field out of the cached object.

"Lookup" is an overloaded word in Celigo, and the skill separates three cases: a cache, an inline `map` on the step, and a live per-record query. Two more things share the name but live elsewhere — a mid-flow lookup step and transform lookups inside export rules. When a request just says "the lookup", the agent is told to confirm which one is meant first.

Each cache caps at 50 MB, with a 1 GB aggregate per environment. A write is an upsert with no insert-if-absent, so two runs that both read "not there" both proceed — for deduplication the skill points you at a separate ledger instead. A cache has no writable `_integrationId`; register it on the integration or a hook's `integrator-api` calls and `{{getLookupCacheData}}` will not reach it.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-lookup-caches -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/configuring-lookup-caches/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/configuring-lookup-caches/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-lookup-caches -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/configuring-lookup-caches/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-lookup-caches -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/configuring-lookup-caches/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install celigo/ai configuring-lookup-caches
```

2. **Manually: put the files in place**
- File: `.github/skills/configuring-lookup-caches/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-lookup-caches -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/celigo/ai --path skills/configuring-lookup-caches
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/configuring-lookup-caches/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-lookup-caches -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/celigo/ai/tree/HEAD/skills/configuring-lookup-caches/SKILL.md

## When to use it
- map Shopify product IDs to NetSuite internal IDs
- skip records a previous run already processed
- keep a last-sync timestamp between flow runs
- hold a category or zip code table without per-record API calls
- tell which of the three lookup kinds a task means

## Example prompts
- set up a lookup cache mapping Shopify product IDs to NetSuite internal IDs
- reference the cache in the import mapping with `_lookupCacheId` and pull `sku` via `extract`
- register this cache on the integration so `{{getLookupCacheData}}` can read it

# Configuring Lookup Caches

A lookup cache is an **in-memory key-value store** managed by Celigo for fast data retrieval during integration processing. Unlike export-based lookups that query external systems per-record, lookup caches provide sub-millisecond access to pre-loaded reference data without consuming API calls.

Lookup caches handle three concerns:

- **Cache metadata** -- name, description, and whether data is included in templates/cloning
- **Data management** -- loading, retrieving, updating, and purging key-value entries via dedicated data endpoints
- **Size governance** -- each cache has a 50 MB limit; the per-environment aggregate limit across all caches is 1 GB

Lookup caches are consumed by import and export mappings through a lookup entry. The entry references a cache by `_lookupCacheId` and optionally extracts a specific field from the cached object via the `extract` JSON path, and a mapping row uses it by name. On an HTTP import the entry goes in `http.lookups`; on an export, in its Transformation 2.0 rules. This is configured on the import/export resource, not on the cache itself. A request template can also read a cache directly with `{{getLookupCacheData}}` ([Reading a Cache from a Template](#reading-a-cache-from-a-template)).

Used across flows, APIs, and tools.

## "Lookup" -- Which One Is Meant?

"Lookup" is overloaded in Celigo, and a lookup cache is only one thing the word can mean. When a request just says "the lookup," confirm which one before acting -- they live in different places and are configured differently. A single entry in `lookups[]` resolves its value one of three ways:

- **Cached** -- the entry sets `_lookupCacheId` to read a lookup cache (this skill): pre-loaded reference data read in-memory, no per-record external call, as fresh as the last data load.
- **Static map** -- the entry carries an inline `map` object. No cache and no external call; the table travels with the import/export. Best for a handful of stable pairs that rarely change.
```
