catalyst-nosql

catalyst-nosql is a skill for Claude Code from catalystbyzoho/claude-plugin. It costs 108 tokens per session (464 once invoked), scanned A, original, Apache-2.0.

Guidance for using Catalyst NoSQL, a document-style database that stores flexible records as key-value items. It covers records with changing fields, nested objects, and arrays.

In plain words
What is it for?
Adding, reading, changing, deleting, and querying items in Catalyst NoSQL tables with the NoSQLItem builder.
Why use it?
It helps choose this store when data does not fit a fixed table structure, while avoiding it for relational data that needs joins or a fixed schema.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

catalyst-nosql scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

How It Works

  1. NoSQL vs Data Store — Choose NoSQL for flexible/evolving per-item attributes, nested maps/arrays, and high-write-throughput key-value access; choose Data Store for a fixed relational schema, joins, or ACID/ZCQL access. Full comparison table in references/nosql-basics.md. 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…

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

catalyst-nosql is a skill published in the GitHub repository catalystbyzoho/claude-plugin (1 stars, last pushed 26d ago), licensed Apache-2.0. It adds 108 tokens to every session and 464 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
