Our review

Calculates Amazon Keyspaces pricing and analyzes compatibility of Cassandra, CQL, and SQL inputs.

Supports multiple modes: manual inputs, Cassandra diagnostics, SQL translation, compatibility checks
Automatically generates compatibility reports for Cassandra schemas
Translates SQL DDL into three Keyspaces data-model strategies with cost estimates

When to use it

Use this skill when estimating costs for migrating from Cassandra to Keyspaces or planning a new Keyspaces table.

When not to use it

Avoid if you need real-time pricing or lack any workload data.

Examples

Manual pricing input

Estimate the cost of a Keyspaces table in us-east-1 with 1000 reads/s, 500 writes/s, 4KB row size, 100GB storage, no TTL, and PITR enabled.

Compatibility check with pricing

I have a Cassandra schema file. Check compatibility with Keyspaces and then estimate the monthly cost based on the schema.

SQL to Keyspaces translation

Here is my SQL DDL for a table. Can you translate it to a Keyspaces data model and show pricing for all three strategies?

Amazon Keyspaces Pricing Calculator

Invoke the amazon-keyspaces-skill skill (.claude/skills/amazon-keyspaces-skill/SKILL.md) and follow its instructions.

The skill supports five modes:

Manual inputs — user provides region, reads/s, writes/s, row size, storage, TTL, and PITR.
Cassandra diagnostic files — user provides nodetool output, schema, or a directory to scan. When a schema is present, a compatibility report is included alongside the pricing.
Compatibility check — user provides a Cassandra CQL schema (file or pasted) and wants to know what features won't work on Amazon Keyspaces.
SQL → Keyspaces translation — user provides SQL DDL; the skill prices 3 data-model strategies.
Connection / driver configuration — user asks about or shares an Apache Cassandra driver config for connecting to Amazon Keyspaces; the skill reviews or advises (no scripts).

Arguments (optional, passed through to Mode 1): [region] [reads/s] [writes/s] [row-size-bytes] [storage-gb] [ttl/s] [pitr]

Example: /amazon-keyspaces-skill us-east-1 1000 500 4096 100 0 true

If the user provides arguments, use Mode 1 directly. Otherwise, let the skill's logic decide the correct mode based on the user's inputs.
