## What it does

The skill equips coding agents with knowledge of Amazon Keyspaces compatibility, pricing, and infrastructure operations. It handles CLI commands for creating multi-region keyspaces, configuring UDTs, updating TTL, and setting up point-in-time recovery. Every creation command automatically appends required metadata tags: `created_by=keyspaces-skill` and `generation_model`.

Safety rules prevent unconfirmed changes: the assistant must request approval before applying modifications. Configuring auto-scaling will fail unless the IAM service-linked role `AWSServiceRoleForApplicationAutoScaling_CassandraTable` already exists in your AWS account.

The skill also calculates pre-warming throughput to avoid throttling during batch loads and sets up CDC streams with views like `NEW_IMAGE` or `KEYS_ONLY`. When switching capacity modes between on-demand and provisioned, the agent explicitly warns about brief throttling risks.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-keyspaces -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-keyspaces -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-keyspaces -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws amazon-keyspaces
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-keyspaces -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path skills/specialized-skills/database-skills/amazon-keyspaces
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-keyspaces -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/aws/agent-toolkit-for-aws/tree/HEAD/skills/specialized-skills/database-skills/amazon-keyspaces/SKILL.md

## When to use it
- calculate pre-warming throughput before scheduled traffic spikes
- enable CDC streams with specific row-image views
- configure application auto-scaling for read and write capacity
- validate Apache Cassandra schema compatibility for Keyspaces migration

## Example prompts
- Check if my Cassandra table schema is compatible with Amazon Keyspaces
- Configure CDC on the payments table with NEW_AND_OLD_IMAGES
- Set up auto-scaling targets for our Keyspaces user table

  Provides authoritative compatibility checks, pricing estimates, connection troubleshooting,

  diagnostics parsing, SQL-to-Cassandra migration, and Cassandra-to-Keyspaces migration
  scenarios. Agents frequently produce incomplete or incorrect answers about Keyspaces

# Amazon Keyspaces

## Safety guidance

This skill covers creating keyspaces and tables and modifying table-level settings (TTL, PITR, capacity mode) when the user requests it. The agent MUST confirm the action with the user before executing. Do NOT execute any create or modify operation without explicit user confirmation (e.g., "yes", "proceed", "confirmed", "go ahead"). If the user has not confirmed, present the planned action and ask for approval.

### Execute these operations (after user confirmation)

- Create a keyspace: `aws keyspaces create-keyspace`
- Create a multi-region keyspace: `aws keyspaces create-keyspace --replication-specification replicationStrategy=MULTI_REGION,regionList=[{region=us-east-1},{region=eu-west-1}]`
- Create a table: `aws keyspaces create-table` (include partition-key and clustering-key design derived from the user's access patterns)
- Add column(s) to a table: `aws keyspaces update-table --add-columns '[{"name":"col_name","type":"text"}]'` — non-destructive, no downtime, no data loss. Existing rows get null for the new column.
- Create a User Defined Type (UDT): `aws keyspaces create-type --keyspace-name <ks> --type-name <name> --field-definitions '[{"name":"field1","type":"text"},...]'`
- Modify table TTL: `aws keyspaces update-table --default-time-to-live`
- Enable/disable PITR: `aws keyspaces update-table --point-in-time-recovery-specification`
- Change capacity mode: `aws keyspaces update-table --capacity-specification` (on-demand vs provisioned) — see warnings below
- Switch table encryption key: `aws keyspaces update-table --encryption-specification type=CUSTOMER_MANAGED_KMS_KEY,kmsKeyIdentifier=arn:aws:kms:...` — no downtime or availability loss. Can also switch back to AWS owned key with `type=AWS_OWNED_KMS_KEY`.
