Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00103 | $0.01321 |
| Opus 5 | $0.00051 | $0.00660 |
| Sonnet 5 | $0.00021 | $0.00264 |
| Haiku 4.5 | $0.00010 | $0.00132 |
Grade A, and why
cassandra-docs 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apache Cassandra questions are easy to answer from stale memory or relational-database assumptions. Use this skill to ground answers in the official Apache Cassandra documentation and return the closest authoritative page instead of generic wide-column or NoSQL advice.
When to Use
Use this skill when the request is about:
- Cassandra concepts: keyspaces, tables, partitions, clustering keys, and replicas
- Getting started, installation, configuration, and production recommendations
- CQL syntax, DDL, DML, data types, functions, operators, and security
- Data modeling: query-first design, denormalization, and physical modeling
- Storage Attached Indexing (SAI) and secondary indexes (2i)
- Vector search, materialized views, and JSON support
- Replication, consistency levels, snitches, and topology changes
- Compaction, repair, hints, backups, and CDC
- Security, authentication, authorization, and audit logging
- Tools: cqlsh, nodetool, SSTable tools, and cassandra-stress
- Architecture, storage engine, and native protocol behavior
- Troubleshooting cluster health, performance, and misbehaving nodes
Do not use this skill for:
- ScyllaDB-specific features, Alternator, or shard-aware drivers. Use
scylladb-docsinstead. - Amazon DynamoDB tables, items, or GSIs. Use
aws-dynamodb-docsinstead. - MongoDB documents or aggregation pipelines. Use
mongodb-docsinstead. - DataStax Enterprise or Astra features unless the question maps to open-source Cassandra docs.
Workflow
1. Classify the request
Decide which bucket the question belongs to before searching:
- Getting started and installation
- Architecture and core concepts
- Data modeling and schema design
- CQL language and reference
- Indexing: SAI and secondary indexes
- Vector search
- Configuration and operating procedures
- Replication, repair, and compaction
- Security and auditing
- Tools and administration
- Troubleshooting and FAQ
- Reference and native protocol
If you need a quick starting point, load references/topic-map.md and jump to the closest section.
What ships with it
2 files 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.
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.

cassandra-docs is a skill published in the GitHub repository cookieMonsterDev/agents-skills (4 stars, last pushed 16d ago), licensed MIT. It adds 103 tokens to every session and 1,321 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 2026-08-31.
