## What it does

The skill fires on `nosql.table`, `insertItems`, `fetchItem`, `updateItems`, `deleteItems`, `queryTable` and `NoSQLItem`. The agent gets the SDK operations plus the partition-key model — a record cannot be built without the partition key.

It also ships a decision table for Catalyst Data Store versus Catalyst NoSQL. Fixed schema, ZCQL and joins belong to Data Store, and the skill says to stop and load `catalyst-datastore` instead. Flexible per-item structure, JSON format and write throughput are the NoSQL side. If your project already runs relational queries, this skill is the wrong pick, and that is worth checking before you wire it in.

The agent then loads `references/nosql-basics.md` and answers with the SDK call, the table name, the partition-key attribute and the `NoSQLItem` construction. Install comes from the `catalystbyzoho/agent-skills` repository through `npx skills add`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-nosql -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-nosql -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-nosql -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install catalystbyzoho/agent-skills catalyst-nosql
```

2. **Manually: put the files in place**
- File: `.github/skills/catalyst-nosql/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-nosql -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/catalystbyzoho/agent-skills --path skills/catalyst-nosql
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-nosql -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/catalystbyzoho/agent-skills/tree/HEAD/skills/catalyst-nosql/SKILL.md

## When to use it
- build a NoSQL item with the `NoSQLItem` builder
- insert a batch of records via `insertItems`
- fetch a single record by partition key
- update and delete Catalyst documents
- pick between NoSQL and Data Store before writing code

## Example prompts
- insert a record into nosql.table using NoSQLItem
- show me the fetchItem call for this table
- we have a flexible schema — NoSQL or Data Store?

name: catalyst-nosql
description: "Catalyst NoSQL — key-value table store with typed items built via NoSQLItem builder. Partition key required. Trigger on 'NoSQL', 'nosql.table', 'insertItems', 'fetchItem', 'updateItems', 'deleteItems', 'queryTable', 'NoSQLItem', 'document storage', 'flexible schema', or 'Catalyst document database'. Do NOT use when you need SQL joins, ZCQL queries, or a fixed relational schema — use catalyst-datastore instead."

## How It Works

1. **NoSQL vs Data Store** — If the user is undecided, apply this matrix:

   | | Catalyst Data Store | Catalyst NoSQL |
   |---|---|---|
   | Schema | Fixed, defined upfront | Flexible, per-item (no uniform structure required) |
   | Query | ZCQL (SQL-like joins and filters) | Partition key + optional sort key |
   | Data type | Structured, relational rows | Unstructured/semi-structured, JSON-format |
   | Priority | ACID compliance, complex queries | High scalability, high write throughput |

   **Rule:** If the user says "ZCQL", "join", "relational", or "fixed schema" — stop and load `catalyst-datastore` instead.
2. **Load `references/nosql-basics.md`** — for SDK operations (`insertItems`, `fetchItem`, `updateItems`, `deleteItems`, `queryTable`) and the `NoSQLItem` builder.
3. **Answer** — Provide the SDK method call with the correct table name, partition-key attribute, and `NoSQLItem` construction.

## Triggers

Use this skill for: "NoSQL", "document storage", `nosql.table`, `insertItems`, `fetchItem`, `updateItems`, `deleteItems`, `queryTable`, `NoSQLItem`, "NoSQL vs Data Store", "flexible schema", "Catalyst document database", "schemaless data on Catalyst", or "nested objects in Catalyst".

## References

| Reference | Load when the query is about… |
|-----------|-------------------------------|
| `references/nosql-basics.md` | SDK operations (`insertItems`, `fetchItem`, `updateItems`, `deleteItems`, `queryTable`), `NoSQLItem` builder, partition-key model, NoSQL vs Data Store decision table |
```
